Sodium-glucose cotransporter 2 inhibitors and renin-angiotensin-aldosterone system, possible cellular interactions and benefits. Cell Signal 2024; 122:111335. [PMID: 39117253 DOI: 10.1016/j.cellsig.2024.111335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2024] [Revised: 07/30/2024] [Accepted: 08/04/2024] [Indexed: 08/10/2024]
Abstract
Sodium glucose cotransporter 2 inhibitors (SGLT2is) are a newly developed class of anti-diabetics which exert potent hypoglycemic effects in the diabetic milieu. However, the evidence suggests that they also have extra-glycemic effects. The renin-angiotensin-aldosterone system (RAAS) is a hormonal system widely distributed in the body that is important for water and electrolyte homeostasis as well as renal and cardiovascular function. Therefore, modulating RAAS activity is a main goal in patients, notably diabetic patients, which are at higher risk of complications involving these organ systems. Some studies have suggested that SGLT2is have modulatory effects on RAAS activity in addition to their hypoglycemic effects and, thus, these drugs can be considered as promising therapeutic agents for renal and cardiovascular disorders. However, the exact molecular interactions between SGLT2 inhibition and RAAS activity are not clearly understood. Therefore, in the current study we surveyed the literature for possible molecular mechanisms by which SGLT2is modulate RAAS activity.

Eur J Pharmacol 2024; 977:176742. [PMID: 38880216 DOI: 10.1016/j.ejphar.2024.176742] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Revised: 06/04/2024] [Accepted: 06/13/2024] [Indexed: 06/18/2024]
Abstract
Polycystic ovary syndrome (PCOS), a common endocrine disorder affecting premenopausal women, is associated with various metabolic consequences such as insulin resistance, hyperlipidemia, obesity, and type 2 diabetes mellitus (T2DM). Insulin sensitizers, such as metformin and pioglitazone, though effective, often leads to significant gastrointestinal adverse effects or weight gain, limiting its suitability for women with PCOS. There is an urgent need for safe, effective and affordable agents. Dapagliflozin, a sodium-glucose co-transporter 2 (SGLT2) inhibitor, enhances glucose elimination through urine, thereby reducing body weight and improving glucose and lipid metabolism. Nevertheless, it is not currently recommended as a therapeutic option for PCOS in clinical guidelines. In this study, we systematically examined the impact of dapagliflozin on an obese PCOS mouse model, focusing on alterations in glucose metabolism, adipose tissue morphology, and plasma lipid profile. Obese PCOS was induced in mice by continuous dihydrotestosterone (DHEA) injections over 21 days and high-fat diet (HFD) feeding. PCOS mice were then orally gavaged with dapagliflozin (1 mg/kg), metformin (50 mg/kg), or vehicle daily for 8 weeks, respectively. Our results demonstrated that dapagliflozin significantly prevented body weight gain and reduced fat mass in obese PCOS mice. Meanwhile, dapagliflozin treatment improved glucose tolerance and increased insulin sensitivity compared to the control PCOS mice. Furthermore, dapagliflozin significantly improved adipocyte accumulation and morphology in white adipose tissue, resulting in a normalized plasma lipid profile in PCOS mice. In conclusion, our results suggest that dapagliflozin is an effective agent in managing glucose and lipid metabolism disorders in obese PCOS mice.

Biomed Pharmacother 2024; 177:116994.

Abstract
BACKGROUND Myocardial infarction (MI) has emerged as the primary cause of global mortality. Managing blood sugar levels could play a vital role in the treatment of MI. Dapagliflozin (DPG), a commonly used hypoglycemic drug, has demonstrated efficacy in treating heart failure. However, the impact of DPG on MI remains unclear. We aimed to investigate the effects and mechanisms of DPG in relation to MI. METHODS AND RESULTS DPG administration alleviated MI-induced cardiac dysfunction and myocardial fibrosis. We also found that DPG administration mitigated cardiomyocyte apoptosis through TUNEL staining. CD31 and α-Sma staining revealed that DPG promotes post-MI angiogenesis in mice. In vitro, using scratch assays, transwell assays, and tube formation assays, we discovered that DPG enhanced HUVEC proliferation capacity. Mechanistically, DPG promoted the expression of extracellular matrix genes and mitochondrial function-related genes. Additionally, molecular docking identified the interaction between DPG and PXR, which activated PXR and recruited it to the promoters of Pgam2 and Tcap, promoting their expressions, thus facilitating angiogenesis and post-MI heart repair. CONCLUSIONS DPG promotes angiogenesis by activating PXR, thereby alleviating cardiac dysfunction and fibrosis after myocardial infarction. This study provides new strategies and targets for the treatment of ischemic disease.

Abstract
BACKGROUND Sodium-glucose-cotransporter 2 inhibitors (SGLT2is) have revolutionized the treatment of type 2 diabetes mellitus (DM2) and chronic kidney disease (CKD), reducing the risk of cardiovascular and renal end points by up to 40%. The underlying mechanisms are not fully understood. OBJECTIVE The study aims to examine the effects of empagliflozin versus placebo on renal hemodynamics, sodium balance, vascular function, and markers of the innate immune system in patients with DM2, DM2 and CKD, and nondiabetic CKD. METHODS We conducted 3 double-blind, crossover, randomized controlled trials, each with identical study protocols but different study populations. We included patients with DM2 and preserved kidney function (estimated glomerular filtration rate >60 mL/min/1.73 m2), DM2 and CKD, and nondiabetic CKD (both with estimated glomerular filtration rate 20-60 mL/min/1.73 m2). Each participant was randomly assigned to 4 weeks of treatment with either 10 mg of empagliflozin once daily or a matching placebo. After a wash-out period of at least 2 weeks, participants were crossed over to the opposite treatment. End points were measured at the end of each treatment period. The primary end point was renal blood flow measured with 82Rubidium positron emission tomography-computed tomography (82Rb-PET/CT). Secondary end points include glomerular filtration rate measured with 99mTechnetium-diethylene-triamine-pentaacetate (99mTc-DTPA) clearance, vascular function assessed by forearm venous occlusion strain gauge plethysmography, measurements of the nitric oxide (NO) system, water and sodium excretion, body composition measurements, and markers of the complement immune system. RESULTS Recruitment began in April 2021 and was completed in September 2022. Examinations were completed by December 2022. In total, 49 participants completed the project: 16 participants in the DM2 and preserved kidney function study, 17 participants in the DM2 and CKD study, and 16 participants in the nondiabetic CKD study. Data analysis is ongoing. Results are yet to be published. CONCLUSIONS This paper describes the rationale, design, and methods used in a project consisting of 3 double-blind, crossover, randomized controlled trials examining the effects of empagliflozin versus placebo in patients with DM2 with and without CKD and patients with nondiabetic CKD, respectively.

Abstract
A new class of antidiabetic drugs - gliflozins (inhibitors of sodium glucose cotransporter-2; SGLT-2i) stimulate glucose and sodium excretion, thereby contributing to improved glycemic control, weight loss and blood pressure reduction in diabetic patients. Large clinical trials in patients with type 2 diabetes treated with empagliflozin, canagliflozin or dapagliflozin have demonstrated their excellent efficacy in improving many cardiovascular outcomes, including the reduction of death from cardiovascular diseases, non-fatal myocardial infarction or stroke, and hospitalization for heart failure. Moreover, the beneficial effects of SGLT-2i were also demonstrated in the decrease in proteinuria, which leads to a lower risk of progression to end-stage renal disease and thus a delay in initiation of the renal replacement therapy. Unexpectedly, their cardioprotective and renoprotective effects have been demonstrated not only in patients with diabetes but also in those without diabetes. Recently, much effort has been focused on patients with heart failure (either with reduced or preserved ejection fraction) or liver disease. Experimental studies have highlighted pleiotropic effects of SGLT-2 inhibitors beyond their natriuretic and glycosuric effects, including reduction of fibrosis, inflammation, reactive oxygen species, and others. Our results in experimental non-diabetic models of hypertension, chronic kidney disease and heart failure are partially consistent with these findings. This raises the question of whether the same mechanisms are at work in diabetic and non-diabetic conditions, and which mechanisms are responsible for the beneficial effects of gliflozins under non-diabetic conditions. Are these effects cardio-renal, metabolic, or others? This review will focus on the effects of gliflozins under different pathophysiological conditions, namely in hypertension, chronic kidney disease, and heart failure, which have been evaluated in non-diabetic rat models of these diseases. Key words: SGLT-2 inhibitor, hypertension, chronic kidney disease, heart failure, liver disease, rat.

Abstract
BACKGROUND Real-world Indian studies evaluating effectiveness of dapagliflozin as an add-on to other oral antidiabetic drugs (OAD) in patients with type 2 diabetes mellitus (DM) are scarce. METHODS An electronic medical record (EMR)-based, retrospective, multicentre study was conducted to evaluate the effectiveness of dapagliflozin as add-on therapy in adult patients with inadequately controlled DM on metformin with or without other OAD. Baseline characteristics (visit 1: metformin or metformin plus OAD treatment for at least 30 days) and treatment-related outcomes (visit 2: follow-up) considered between 60 and 140 days after adding/switching dapagliflozin [glycated haemoglobin (HbA1c), body mass index (BMI), systolic blood pressure (SBP) and diastolic blood pressure (DBP)] were analysed. RESULTS A total of 3616 patients were screened from 478 centres. Most patients had received dapagliflozin (D) + metformin (M) + at least one other OAD [D + M + OAD, n = 2907 (80.4%), 408 followed-up with HbA1c reported], while 709 patients (19.6%, 138 followed-up with HbA1c reported) received dapagliflozin + metformin (D + M). Treatment with dapagliflozin as an add-on therapy resulted in significant change in HbA1c (-1.1 ± 1.44%; p < 0.05 for HbA1c subgroup ≥ 7.5%; -1.6 ± 1.41%; p < 0.05 for HbA1c subgroup ≥ 8%) at visit 2 compared with visit 1. Significant change in body weight (-1.4 ± 3.31 kg; p < 0.05 for HbA1c subgroup ≥ 7.5%; - 1.5 ± 3.22 kg; p < 0.05 for HbA1c subgroup ≥ 8%) was observed at visit 2. Similarly, a significant change in BMI was noted for the HbA1c subgroup ≥ 7.5% (-1.0 ± 8.38 kg/m2). However, the change in BMI in the HbA1c subgroup ≥ 8% was noted to be -1.4 ± 10.4 kg/m2, which was not statistically significant (p = 0.08). In the overall study population, significant change in the SBP (-4.5 ± 14.9 mmHg; p < 0.05 for HbA1c subgroup ≥ 7.5%; -4.5 ± 15.1 mmHg; p < 0.0001 for HbA1c subgroup ≥ 8%) was observed at visit 2 compared with visit 1. On identical lines, significant change in DBP (-1.5 ± 8.94 mmHg; p < 0.05 for HbA1c subgroup ≥ 7.5%; -1.4 ± 8.91 mmHg; p < 0.05 for HbA1c subgroup ≥ 8%) was noted. CONCLUSIONS Dapagliflozin showed significant improvement in glycemic parameter, BMI and BP when added to metformin, with or without other OADs in a real-world scenario.

Abstract
BACKGROUND Sodium-glucose co-transporter 2 inhibitors (SGLT2is) are part of the standard of care for patients with chronic kidney disease (CKD), both with and without type 2 diabetes. Endothelin A (ETA) receptor antagonists have also been shown to slow progression of CKD. Differing mechanisms of action of SGLT2 and ETA receptor antagonists may enhance efficacy. We outline a study to evaluate the effect of combination zibotentan/dapagliflozin versus dapagliflozin alone on albuminuria and estimated glomerular filtration rate (eGFR). METHODS We are conducting a double-blind, active-controlled, Phase 2b study to evaluate the efficacy and safety of ETA receptor antagonist zibotentan and SGLT2i dapagliflozin in a planned 415 adults with CKD (Zibotentan and Dapagliflozin for the Treatment of CKD; ZENITH-CKD). Participants are being randomized (1:2:2) to zibotentan 0.25 mg/dapagliflozin 10 mg once daily (QD), zibotentan 1.5 mg/dapagliflozin 10 mg QD and dapagliflozin 10 mg QD alone, for 12 weeks followed by a 2-week off-treatment wash-out period. The primary endpoint is the change in log-transformed urinary albumin-to-creatinine ratio (UACR) from baseline to Week 12. Other outcomes include change in blood pressure from baseline to Week 12 and change in eGFR the study. The incidence of adverse events will be monitored. Study protocol-defined events of special interest include changes in fluid-related measures (weight gain or B-type natriuretic peptide). RESULTS A total of 447 patients were randomized and received treatment in placebo/dapagliflozin (n = 177), zibotentan 0.25 mg/dapagliflozin (n = 91) and zibotentan 1.5 mg/dapagliflozin (n = 179). The mean age was 62.8 years, 30.9% were female and 68.2% were white. At baseline, the mean eGFR of the enrolled population was 46.7 mL/min/1.73 m2 and the geometric mean UACR was 538.3 mg/g. CONCLUSION This study evaluates the UACR-lowering efficacy and safety of zibotentan with dapagliflozin as a potential new treatment for CKD. The study will provide information about an effective and safe zibotentan dose to be further investigated in a Phase 3 clinical outcome trial. CLINICAL TRIAL REGISTRATION NUMBER NCT04724837.

Eur J Pharm Sci 2024; 192:106644. [PMID: 37981049 DOI: 10.1016/j.ejps.2023.106644] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 10/18/2023] [Accepted: 11/16/2023] [Indexed: 11/21/2023]
Abstract
INTRODUCTION SY-009 produces a hypoglycemic effect via inhibiting sodium/glucose cotransporter 1 (SGLT1) in type 2 diabetes mellitus (T2DM) patients. This randomized, double-blind, placebo-controlled, and multiple-dose escalation clinical trial aimed to evaluate the pharmacokinetic and pharmacodynamical characteristics as well as the safety and tolerability of SY-009 in T2DM patients. METHOD Fifty T2DM patients were randomized into experimental and placebo groups, and hospitalized for 9 days managed with a unified diet and rest management. Subjects were given SY-009 or placebo from day 1 to day 7 at different frequencies and dosages. Single dose cohort was defined as the first dose on day 1 and multiple dose cohort included all the dose from day 1 to 7. Blood samples were collected for pharmacokinetic analysis. Mixed meal tolerance tests were performed. Blood samples were collected to determine glucose, C-peptide, insulin, glucagon-like peptide-1 (GLP-1), and gastric inhibitory polypeptide (GIP). RESULTS PK parameters were not obtained because blood SY-009 concentrations were below the limit of quantitation in all subjects. SY-009 decreased the postprandial glucose. Blood glucose was controlled within 4 hours after taking the drug. Short-term administration of SY-009 (7 days) had no significant effects on fasting glucose but reduced the secretion of C-peptide, insulin, and GIP and increased GLP-1 secretion. The most common adverse event was gastrointestinal disorder manifesting abdominal pain, diarrhea, and bloating. CONCLUSION Plasma exposure of SY-009 and its metabolites was fairly low in T2DM patients at doses of 1.0-4.0 mg. SY-009 reduced postprandial glucose, C-peptide, and insulin levels, showing relative safety and tolerability in the dose range of 1.0-4.0 mg.

Abstract
BACKGROUND Decreasing hyperinsulinemia is crucial in preventing laminitis in insulin dysregulated (ID) horses. Complementary pharmacological treatments that efficiently decrease postprandial hyperinsulinemia in ID horses are needed. OBJECTIVES Compare short-term effects of canagliflozin vs placebo on glucose and insulin responses to an oral sugar test (OST) as well as the effects on body weight and triglyceride concentrations in horses with ID. ANIMALS Sixteen privately-owned ID horses. METHODS A single-center, randomized, double-blind, placebo-controlled, parallel design study. The horses were randomized (ratio 1:1) to either once daily PO treatment with 0.6 mg/kg canagliflozin or placebo. The study consisted of an initial 3-day period for obtaining baseline data, a 3-week double-blind treatment period at home, and a 3-day follow-up period similar to the initial baseline period but with continued double-blind treatment. Horses were subjected to an 8-sample OST in the morning of the third day on both visits. RESULTS Maximal geometric least square (LS) mean insulin concentration (95% confidence interval [CI]) during the OST decreased after 3 weeks of canagliflozin treatment compared with placebo (83.2; 55.4-125.0 vs 215.2; 143.2-323.2 μIU/mL). The geometric LS mean insulin response (insulin AUC0-180 ) for canagliflozin-treated horses was >66% lower compared with placebo. Least square mean body weight decreased by 11.1 (4-18.1) kg and LS mean triglyceride concentrations increased by 0.99 (0.47-1.5) mmol/L with canagliflozin treatment. CONCLUSIONS AND CLINICAL IMPORTANCE Canagliflozin is a promising drug for treatment of ID horses that requires future studies.

Dapagliflozin attenuates high glucose-and hypoxia/reoxygenation-induced injury via activating AMPK/mTOR-OPA1-mediated mitochondrial autophagy in H9c2 cardiomyocytes. Arch Physiol Biochem 2023:1-11. [PMID: 37655809 DOI: 10.1080/13813455.2023.2252200] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 08/07/2023] [Accepted: 08/21/2023] [Indexed: 09/02/2023]
Abstract
This study investigated the protective effect of dapagliflozin on H9c2 cardiomyocyte function under high glucose and hypoxia/reoxygenation (HG-H/R) conditions and identified the underlying molecular mechanisms. Dapagliflozin reduced the level of lactate dehydrogenase and reactive oxygen species in cardiomyocytes under HG-H/R conditions and was accompanied by a decrease in caspase-3/9 activity. In addition, Dapagliflozin significantly reduced mitochondrial permeability transition pore opening and increased ATP content, accompanied by upregulation of OPA1 with autophagy-related protein molecules and activation of the AMPK/mTOR signalling pathway in HG-H/R treated cardiomyocytes. OPA1 knockdown or compound C treatment attenuated the protective effects of dapagliflozin on the cardiomyocytes under HG-H/R conditions. Downregulation of OPA1 expression increased mitochondrial intolerance in cardiomyocytes during HG-H/R injury and the AMPK-mTOR-autophagy signalling is a key mechanism for protecting mitochondrial function and reducing cardiomyocyte apoptosis. Collectively, dapagliflozin exerted protective effects on the cardiomyocytes under HG-H/R conditions. Dapagliflozin attenuated myocardial HG-H/R injury by activating AMPK/mTOR-OPA1-mediated mitochondrial autophagy.

Abstract
Heart failure (HF) is a multifactorial clinical syndrome involving many complex processes. The causes may be related to abnormal heart structure and/or function. Changes in the renin-angiotensin-aldosterone system, the sympathetic nervous system, and the natriuretic peptide system are important in the pathophysiology of HF. Dysregulation or overexpression of these processes leads to changes in cardiac preload and afterload, changes in the vascular system, peripheral vascular dysfunction and remodeling, and endothelial dysfunction. One of the important factors responsible for the development of heart failure at the cellular level is oxidative stress. This condition leads to deleterious cellular effects as increased levels of free radicals gradually disrupt the state of equilibrium, and, as a consequence, the internal antioxidant defense system is damaged. This review focuses on pharmacotherapy for chronic heart failure with regard to oxidation-reduction metabolism, with special attention paid to the latest group of drugs, SGLT2 inhibitors-an integral part of HF treatment. These drugs have been shown to have beneficial effects by protecting the antioxidant system at the cellular level.

Abstract
Type 1 diabetes mellitus (T1DM) is an autoimmune disease characterized by abnormally high blood glucose concentrations due to dysfunction of the insulin-producing beta-cells in the pancreas. Dapagliflozin, an inhibitor of renal glucose reabsorption, has the potential to improve often suboptimal glycemic control in patients with T1DM through insulin-independent mechanisms and to partially mitigate the adverse effects associated with long-term insulin administration. In this work, we have adapted a systems pharmacology model of type 2 diabetes mellitus to describe the T1DM condition and characterize the effect of dapagliflozin on short- and long-term glycemic markers under various treatment scenarios. The developed platform serves as a quantitative tool for the in silico evaluation of the insulin-glucose-dapagliflozin crosstalk, optimization of the treatment regimens, and it can be further expanded to include additional therapies or other aspects of the disease.

Abstract
AIM To apply model-informed drug development (MIDD) approach to support the decision making in drug development and accelerate the clinical development of janagliflozin, an orally selective SGLT2 inhibitor. METHOD We previously developed a mechanistic pharmacokinetic/pharmacodynamic (PK/PD) model of janagliflozin based on preclinical data to optimize dose design in the first-in-human (FIH) study. In the current study, we used clinical PK/PD data of the FIH study to validate the model and then simulate the PK/PD profiles of multiple ascending dosing (MAD) study in healthy subjects. Besides, we developed a population PK/PD model of janagliflozin to predict steady-state urinary glucose excretion (UGE [UGE,ss]) in healthy subjects in the Phase 1 stage. This model was subsequently used to simulate the UGE, ss in patients with type 2 diabetes mellitus (T2DM) based on a unified PD target (ΔUGEc) across healthy subjects and patients with T2DM. This unified PD target was estimated from our previous work of model-based meta-analysis (MBMA) for the same class of drugs. The model-simulated UGE,ss in patients with T2DM was validated by data from the clinical Phase 1e study. Finally, at the end of the Phase 1 study, we simulated the 24-week hemoglobin A1c (HbA1c) level in patients with T2DM of janagliflozin based on the quantitative UGE/FPG/HbA1c relationship informed by our previous MBMA study for the same class of drugs. RESULTS The pharmacologically active dose (PAD) levels of multiple ascending dosing (MAD) study were estimated to be 25, 50,100 mg once daily (QD) for 14 days based on the effective PD target of approximately 50 g daily UGE in healthy subjects. Besides, our previous MBMA analysis for the same class of drugs has provided a unified effective PD target of ΔUGEc approximately 0.5-0.6 g/(mg/dL) in both healthy subjects and patients with T2DM. In this study, the model-simulated steady-state ΔUGEc (ΔUGEc,ss) of janagliflozin in patients with T2DM were 0.52, 0.61 and 0.66 g/(mg/dL) for 25, 50, 100 mg QD dose levels. Finally, we estimated that HbA1c at 24 weeks would decrease 0.78 and 0.93 from baseline for the 25 and 50 mg QD dose groups. CONCLUSIONS The application of MIDD strategy adequately supported the decision making at each stage of janagliflozin development process. A waiver of Phase 2 study was successfully approved for janagliflozin based on these model-informed results and suggestions. This MIDD strategy of janagliflozin could be further utilized to support the clinical development of other SGLT2 inhibitors.

Abstract
SGLT2 inhibitors (SGLT2i) are emerging as a novel therapy for type 2 diabetes due to their effective hypoglycemic and potential cardio- and nephroprotective effects, while caloric restriction (CR) is a common behavioral modification to improve adiposity and insulin resistance. Therefore, both interventions simultaneously may potentially further improve metabolic syndrome by enhancing carbohydrate metabolism. To test this hypothesis, cohorts of 10-week old, male Long Evans Tokushima Otsuka (LETO) and Otsuka Long Evans Tokushima Fatty (OLETF) rats were treated with SGLT2i (10 mg luseoglifozin/kg/day x 4 wks) (OLETF only) and/or 30% CR (2 wks at 12 weeks of age). CR maintained body mass in both strains while SGLT2i alone did not have any effect on body mass. Simultaneous treatments decreased SBP in OLETF vs SGLT2i alone, decreased insulin resistance index (IRI), and increased creatinine clearance vs OLETF ad lib. Conversely, CR decreased albuminuria independent of SGLT2i. In conclusion, SGLT2i treatment by itself did not elicit significant improvements in insulin resistance, kidney function or blood pressure. However, when combined with CR, these changes where more profound than with CR alone without inducing chronic hypoglycemia.

Abstract
With the emergence of sodium-glucose cotransporter 2 inhibitors (SGLT2i), the treatment of type 2 diabetes mellitus (T2DM) has achieved a new milestone, of which the insulin-independent mechanism could produce weight loss, improve insulin resistance (IR) and exert other protective effects. Besides the well-acknowledged biochemical processes, the dysregulated balance between sympathetic and parasympathetic activity may play a significant role in IR and obesity. Weight loss caused by SGLT-2i could be achieved via activating the liver-brain-adipose neural axis in adipocytes. We previously demonstrated that SGLT-2 are widely expressed in central nervous system (CNS) tissues, and SGLT-2i could inhibit central areas associated with autonomic control through unidentified pathways, indicating that the role of the central sympathetic inhibition of SGLT-2i on blood pressure and weight loss. However, the exact pathway of SGLT2i related to these effects and to what extent it depends on the neural system are not fully understood. The evidence of how SGLT-2i interacts with the nervous system is worth exploring. Therefore, in this review, we will illustrate the potential neurological processes by which SGLT2i improves IR in skeletal muscle, liver, adipose tissue, and other insulin-target organs via the CNS and sympathetic nervous system/parasympathetic nervous system (SNS/PNS).

Abstract
Dapagliflozin (dapa) and empagliflozin (empa) are sodium-glucose cotransporter-2 inhibitors (SGLT2is) that reduce morbidity and mortality in heart failure (HF) patients. Sodium and inward rectifier K+ currents (INa and IK1), carried by Nav1.5 and Kir2.1 channels, respectively, are responsible for cardiac excitability, conduction velocity, and refractoriness. In HF patients, Nav1.5 and Kir2.1 expression are reduced, enhancing risk of arrhythmia. Incubation with dapa or empa (24-h,1 µM) significantly increased INa and IK1 densities recorded in human-induced pluripotent stem cell-cardiomyocytes (hiPSC-CMs) using patch-clamp techniques. Dapa and empa, respectively, shifted to more hyperpolarized potentials the INa activation and inactivation curves. Identical effects were observed in Chinese hamster ovary (CHO) cells that were incubated with dapa or empa and transiently expressed human Nav1.5 channels. Conversely, empa but not dapa significantly increased human Kir2.1 currents in CHO cells. Dapa and empa effects on INa and IK1 were also apparent in Ca-calmodulin kinase II-silenced CHO cells. Cariporide, a Na+/H+ exchanger type 1 (NHE1) inhibitor, did not increase INa or IK1 in hiPSC-CMs. Dapa and empa at therapeutic concentrations increased INa and IK1 in healthy human cardiomyocytes. These SGLT2is could represent a new class of drugs with a novel and long-pursued antiarrhythmic mechanism of action.

Abstract
Objective To investigate the incidence of genital infection due to the use of sodium-glucose cotransporter-2 (SGLT-2) inhibitors in patients with type 2 diabetes mellitus (T2DM) concomitant coronary artery diseases (CAD). Methods A single-center, physician-initiated study was conducted at a tertiary-care center in India. The study enrolled patients with T2DM who were taking SGLT-2 inhibitors for at least two months and divided them into two groups: patients with concomitant CAD as the case group and without CAD as the control group. Demographic data and medical history of patients were documented using a standard questionnaire. Itching and swelling were the signs used for the diagnosis of genital infection. Results A total of 270 consecutive patients with T2DM were enrolled and divided into two groups: 48 patients with CAD as the case group and 222 patients without CAD as the control group. The mean age of patients with CAD was 63.27±7.53 years and without CAD was 58.32±14.89 years. The mean HbA1C levels were 8.40±1.71% in the case group and 8.60±7.20% in the control group. A total of 14.6% of patients with CAD and 12.6% of patients without CAD were found to have genital infections (p=0.712). SGLT-2 inhibitors were stopped in only six patients who had genital infections and all the patients were managed using anti-fungal cream and via maintenance of proper hygiene. The overall incidence of genital infection was about 12.96%, of which only 2.7% required discontinuation of this crucial therapy. Conclusion In conclusion, the incidence of genital infection with the use of SGLT-2 inhibitors is similar among patients with T2DM with concomitant CAD and without CAD. The measures to prevent genital infection should be strongly emphasized. However, larger, well-designed studies are required to validate the current findings.

The New Role of SGLT2 Inhibitors in the Management of Heart Failure: Current Evidence and Future Perspective. Pharmaceutics 2022; 14:pharmaceutics14081730. [PMID: 36015359 PMCID: PMC9416279 DOI: 10.3390/pharmaceutics14081730] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2022] [Revised: 08/10/2022] [Accepted: 08/16/2022] [Indexed: 11/24/2022] Open
Abstract
The sodium-glucose transporter 2 inhibitors (SGLT2i) are a relatively new class of medication used in the management of type 2 diabetes. Recent clinical trials and research have demonstrated this class’s effectiveness in treating heart failure, since they reduce the risk of cardiovascular events, hospitalization, and mortality. The mechanism by which they do so is unclear; however, SGLT2i inhibit the tubular reabsorption of glucose, lowering the interstitial volume. This mechanism leads to a reduction in blood pressure and an improvement of endothelial function. As a result, improvements in hospitalization and mortality rate have been shown. In this review, we focus on the primary outcome of the clinical trials designed to investigate the effect of SGLT2i in heart failure, regardless of patients’ diabetic status. Furthermore, we compare the various SGLT2i regarding their risk reduction to investigate their potential as a treatment option for patients with reduced ejection fraction and preserved ejection fraction.

Abstract
Sodium-glucose cotransporter 2 (SGLT-2) inhibitors (gliflozins) represent the most recently approved class of oral antidiabetic drugs. SGLT-2 overexpression in diabetic patients contributes significantly to hyperglycemia and related complications. Therefore, SGLT-2 became a highly interesting therapeutic target, culminating in the approval for clinical use of dapagliflozin and analogues in the past decade. Gliflozins improve glycemic control through a novel insulin-independent mechanism of action and, moreover, exhibit significant cardiorenal protective effects in both diabetic and nondiabetic subjects. Therefore, gliflozins have received increasing attention, prompting extensive structure-activity relationship studies and optimization approaches. The discovery that intestinal SGLT-1 inhibition can provide a novel opportunity to control hyperglycemia, through a multifactorial mechanism, recently encouraged the design of low adsorbable inhibitors selectively directed to the intestinal SGLT-1 subtype as well as of dual SGLT-1/SGLT-2 inhibitors, representing a compelling strategy to identify new antidiabetic drug candidates.

Abstract
AIMS To assess the effect of sodium-glucose cotransporter-2 inhibitor dapagliflozin on natriuresis, blood pressure (BP) and volume status in patients with chronic kidney disease (CKD) without diabetes. MATERIALS AND METHODS We performed a mechanistic open-label study (DAPASALT) to evaluate the effects of dapagliflozin on 24-hour sodium excretion, 24-hour BP, extracellular volume, and markers of volume status during a standardized sodium diet (150 mmol/d) in six patients with CKD. In parallel, in a placebo-controlled double-blind crossover trial (DIAMOND), we determined the effects of 6 weeks of dapagliflozin on markers of volume status in 53 patients with CKD. RESULTS In DAPASALT (mean age 65 years, mean estimated glomerular filtration rate [eGFR] 39.4 mL/min/1.73 m2 , median urine albumin:creatinine ratio [UACR] 111 mg/g), dapagliflozin did not change 24-hour sodium and volume excretion during 2 weeks of treatment. Dapagliflozin was associated with a modest increase in 24-hour glucose excretion on Day 4, which persisted at Day 14 and reversed to baseline after discontinuation. Mean 24-hour systolic BP decreased by -9.3 (95% confidence interval [CI] -19.1, 0.4) mmHg after 4 days and was sustained at Day 14 and at wash-out. Renin, angiotensin II, urinary aldosterone and copeptin levels increased from baseline. In DIAMOND (mean age 51 years, mean eGFR 59.0 mL/min/1.73 m2 , median UACR 608 mg/g), compared to placebo, dapagliflozin increased plasma renin (38.5 [95% CI 7.4, 78.8]%), aldosterone (19.1 [95% CI -5.9, 50.8]%), and copeptin levels (7.3 [95% CI 0.1, 14.5] pmol/L). CONCLUSIONS During a standardized sodium diet, dapagliflozin decreased BP but did not increase 24-hour sodium and volume excretion. The lack of increased natriuresis and diuresis may be attributed to activation of intra-renal compensatory mechanisms to prevent excessive water loss.

Abstract
INTRODUCTION Sodium-dependent glucose cotransporter 2 (SGLT2) is a glucose transporter expressed on the proximal tubular cells, where it reabsorbs glucose from the glomerular filtrate. SGLT2 inhibitors (SGLT2is), initially developed as an antidiabetic drug, have recently attracted considerable attention because they have cardiorenal protective effects. Among SGLT2is, dapagliflozin was the first to demonstrate the renoprotective effect in patients with and without diabetes and has been approved for chronic kidney disease (CKD) treatment. AREAS COVERED This review covers the pharmacological characteristics and the clinical efficacy and safety profiles of dapagliflozin, including comparison with other SGLT2is and risk modification strategies. EXPERT OPINION In DAPA-CKD, dapagliflozin reduced the primary outcome (≥50% estimated glomerular filtration rate [eGFR] decline, end-stage kidney disease [ESKD], or renal or cardiovascular [CV] death) by 39% in CKD patients. This beneficial effect was consistent across prespecified subgroups, including those based on the presence of diabetes. Dapagliflozin also decreased the CV composite outcome and all-cause death by 29% and 31%, respectively. Although an increased risk of adverse events such as ketoacidosis and volume depletion has been reported, the robust renal and CV benefits of dapagliflozin are expected to outweigh potential risks. SGLT2is, including dapagliflozin, will constitute the mainstay of CKD treatment.

Abstract
This meta-analysis was performed to compare the influence of sodium-glucose co-transporter 2 inhibitors (SGLT2i) on the efficacy and safety of elderly patients with type 2 diabetes with the young ones. PubMed, Medline, Web of Science, EMbase, and Cochrane Library were searched for literature published before March 2020 to identify studies comparing efficacy and safety of SGLT2i in elderly diabetes patients (≥65 years) and young controls (<65 years). A fixed or random-effect model was used to calculate the summary standard means difference and odds ratios. A total of 13 articles with data for 86,433 participants were included. Old patients receiving SGLT2i had a smaller reduction in hemoglobin A1c (SMD = -0.07, 95% CI -0.14 to -0.00, p = 0.044) than young ones. They had higher incidence of serious adverse events (SAEs) (OR 1.78, 95% CI 1.25-2.55, p = 0.001), AE leading to discontinuation (OR 2.34, 95%CI 1.53-3.59, p = 0.000), volume depletion (OR 2.80, 95% CI 1.82-4.32, p = 0.000) , and urinary tract infections (OR 1.37, 95% CI 1.18-1.60, p = 0.000), and renal function impairment (OR 2.61, 95% CI 1.78-3.81, p = 0.000) than young patients, and there was a opposite result in genital mycotic infections (OR 0.69, 95% CI 0.55-0.87, p = 0.002). No significant differences were recorded in the reduction of fasting blood glucose, blood pressure, body weight, and in incidence of overall AEs and fracture. In summary, relatively satisfying efficacy was observed in the elderly patients receiving SGLT2i. Although some AEs were more prevalent among older patients, the majority of them were generally mild.

Abstract
BACKGROUND The aim of this study was to investigate the effects of sodium glucose cotransporter 2 inhibitors (SGLT2i) on the glomerulus through the evaluation of podocyturia in patients with diabetic kidney disease (DKD). METHODS The study population was composed of 40 male patients with type 2 diabetes mellitus; 22 of them received SGLT2i (SGLT2i group), and the others who did not were the control. The DKD-related parameters of patients were monitored before SGLT2i initiation, and then in the third and sixth month of the follow-up period. Patients' demographic, clinical, laboratory, and follow-up data were obtained from medical charts. Microalbuminuria was measured in 24-h urine. The number of podocytes in the urine was determined by immunocytochemical staining of two different markers, namely podocalyxin (podx) and synaptopodin (synpo). Concentrations of urine stromal cell-derived factor 1a and vascular endothelial growth factor cytokines were quantified with an enzyme-linked immunosorbent assay kit. RESULTS At the end of the follow-up period, decreases in glycosylated hemoglobin, glucose, systolic and diastolic blood pressure, uric acid level, and microalbuminuria, and improvement in body mass index level and weight loss were significant for the SGLT2i group. On the other hand, there was no significant difference in terms of these parameters in the control group. The excretion of synaptopodin-positive (synpo+ ) and podocalyxin-positive (podx+ ) cells was significantly reduced at the end of the follow-up period for the SGLT2i group, while there was no significant change for the control. CONCLUSIONS At the end of the follow-up period, male patients receiving SGLT2i had better DKD-related parameters and podocyturia levels compared to baseline and the control group. Our data support the notion that SGLT2i might have structural benefits for glomerular health.

Abstract
OBJECTIVE To investigate the clinical efficacy and safety of dapagliflozin in the treatment of diabetic nephropathy (DN). METHODS A total of 120 DN patients admitted to our hospital from June 2017 to March 2020 were divided into control and experimental groups, with 60 cases in each group. The control group received valsartan, and the experimental group received dapagliflozin for 3 months. Body mass index (BMI), hemoglobin A1c (HbA1c), serum creatinine (sCr), uric acid (UA), urine microalbumin (uMA), urine creatinine (uCr), and bilateral kidney function were compared before and after treatment, and adverse reactions in both groups were observed. Serum interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) levels were also evaluated. RESULTS After treatment, except for BMI in the control group, all indexes in both groups were significantly improved. The BMI, HbA1c, sCr, UA, and uMA/uCr ratios of the experimental group were lower than those of the control group. Serum albumin (sAlb) levels were increased in both groups, and the experimental group showed a significant difference compared with the control group. Estimated glomerular filtration rate (eGFR) levels were increased in both groups, and the experimental group was higher than the control group, with no significant differences. Serum IL-6 and TNF-α levels in both groups were lower, and the experimental group was significantly lower than the control group. No serious adverse reactions were observed in either group. CONCLUSION The efficacy of dapagliflozin was demonstrated by its ability to improve diabetes, prevent nephropathy exacerbation, and reduce symptomatic reactions. The low rate of adverse reactions makes dapagliflozin a very safe medication.

Abstract
The lowest dosage of empagliflozin (10 mg) showed similar benefits on glycated hemoglobin (HbA1c) level, body weight, blood pressure, and total and cardiovascular mortality in comparison with the highest available dose (25 mg) in the EMPAREG trial. These findings have not been clearly demonstrated for canagliflozin and dapagliflozin. The objective was to compare the effect of different doses of SGLT2 inhibitors commercially available in Brazil on HbA1c and body weight of patients with type 2 diabetes. MEDLINE, Cochrane and Embase databases were searched from inception until 11th October 2021 for randomized controlled trials of SGLT2 inhibitors in type 2 diabetes patients, lasting at least 12 weeks. HbA1c and body weight variations were described using standard mean difference. We performed direct and indirect meta-analysis, as well as a meta-regression with medication doses as covariates. Eighteen studies were included, comprising 16,095 patients. In the direct meta-analysis, SGLT2 inhibitors reduced HbA1c by 0.62% (95% CI -0.66 to -0.59) and body weight by 0.60 kg (95% CI -0.64 to -0.55). In the indirect meta-analysis, canagliflozin 300 mg ranked the highest regarding reductions in HbA1c and body weight. The remaining medications and dosages were clinically similar, despite some statistically significant differences among them. Canagliflozin 300 mg seems to be more potent in reducing HbA1c and body weight in patients with type 2 diabetes. The remaining SGLT2 inhibitors at different doses lead to similar effects for both outcomes. Whether these glycemic and weight effects are reflected in lower mortality and cardiovascular events is still uncertain and may be a topic for further studies.

Abstract
This study was conducted to evaluate the long-term plasma concentration profiles of dapagliflozin and its effects on the glycated hemoglobin (HbA1c) level, body weight, and estimated glomerular filtration rate (eGFR) in 72 Japanese outpatients with type 2 diabetes mellitus (T2DM) receiving metformin and a dipeptidyl peptidase-4 inhibitor. At baseline, HbA1c level, body weight, and eGFR were 6.9 ± 0.6%, 77.9 ± 13.5 kg, and 78.8 ± 20.7 mL/min/1.73 m2, respectively. A once-daily oral dose of 5 mg dapagliflozin was administered, and its trough plasma concentrations were evaluated at 1, 3, 6, 9, and 12 months. In this study, the patients with stable dapagliflozin concentrations were defined, based on a well-organized clinical trial, as those with average plasma concentrations of 2–5 ng/mL with a coefficient of variation <30%; these values were achieved if patients complied with their once-daily dosage. Multivariate analysis showed a significant decrease in the HbA1c levels among patients with stable concentrations (−0.6 ± 0.4%, p < 0.01), which was greater than the mean change among all 72 patients (−0.2 ± 0.5%, p < 0.01). The patients’ mean body weight also decreased (−2.3 ± 4.0 kg, p = 0.060). Average plasma concentrations ranged from 1.6 to 11.8 ng/mL; however, multivariate analysis indicated it was unrelated to the HbA1c-lowering effect. In conclusion, the long-term stability of plasma dapagliflozin concentration was important in lowering HbA1c level, and a once-daily oral dose of 5 mg was sufficient in achieving this effect.

Abstract
Sodium‐glucose cotransporter‐2 (SGLT‐2) inhibitors are antidiabetic drugs with associated safety concerns regarding the risk of genital and urinary tract infections. This study assessed the risk of genital and urinary tract infections associated with prescription of SGLT‐2 inhibitors as an add‐on therapy to metformin in patients with type 2 diabetes mellitus (T2DM) compared to dipeptidyl peptidase‐4 (DPP‐4) inhibitors, sulfonylurea (SU), and thiazolidinedione (TZD). We conducted a retrospective cohort study using the NHIS—National Health Insurance—Database in Korea from 2014 to 2017. Patients aged ≥19 years and those diagnosed with T2DM prior to drug prescription were enrolled. The outcomes were genital and urinary tract infections. Analysis was performed using Cox's proportional hazard model following 1:1 propensity score matching to calculate the hazard ratio (HR) with a 95% confidence interval (CI). Among the 107 131 patients included in the study, a total of 7738, 7145, and 2175 patients were assigned to the DPP‐4 inhibitors, SU, and TZD comparator groups, using the propensity score (PS) of each comparator based on 7741 people in the assessed drug SGLT‐2 inhibitor group. SGLT‐2 inhibitors were associated with a higher risk of genital infections than DPP‐4 inhibitors (HR: 2.39, 95% CI: 2.07–2.76), SU (HR: 3.23, 95% CI: 2.73–3.81), and TZD (HR: 3.23, 95% CI: 2.35–4.44), as an add‐on therapy to metformin. Similar results were observed for the risk of urinary tract infections. In conclusion, SGLT‐2 inhibitors are significantly associated with a higher risk of genital and urinary tract infections compared to DPP‐4 inhibitors, SU, and TZD.

Abstract
Diabetes mellitus is an ailment that affects a large number of individuals worldwide and its pervasiveness has been predicted to increase later on. Every year, billions of dollars are spent globally on diabetes-related health care practices. Contemporary hyperglycemic therapies to rationalize Type 2 Diabetes Mellitus (T2DM) mostly involve pathways that are insulin-dependent and lack effectiveness as the pancreas' β-cell function declines more significantly. Homeostasis via kidneys emerges as a new and future strategy to minimize T2DM complications. This article covers the reabsorption of glucose mechanism in the kidneys, the functional mechanism of various Sodium- Glucose Cotransporter 2 (SGLT2) inhibitors, their structure and driving profile, and a few SGLT2 inhibitors now accessible in the market as well as those in different periods of advancement. The advantages of SGLT2 inhibitors are dose-dependent glycemic regulation changes with a significant reduction both in the concentration of HbA1c and body weight clinically and statistically. A considerable number of SGLT2 inhibitors have been approved by the FDA, while a few others, still in preliminaries, have shown interesting effects.

Abstract
BACKGROUND We aimed to evaluate the efficacy of sodium-glucose cotransporter 2 (SGLT2) inhibitors for managing obesity in non-diabetic overweight or obese patients. METHODS For purposes of this study, PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials were searched through May 2021. Randomized controlled trials published in English that compared SGLT2 inhibitors with placebo in overweight and obese patients without diabetes were included in the primary analysis. The random effects standardized mean difference ±95% confidence interval (95% CI) was calculated as the effect size. RESULTS Five randomized controlled trials were included to evaluate body weight change, four trials to assess body mass index (BMI), and three trials to assess waist circumference were included. Results showed that the mean body weight loss on SGLT2 inhibitors in obese patients without diabetes was -1.62 kg (95% CI, -2.38 to -0.85 kg) when compared with placebo. Treatment with SGLT2 inhibitors was also associated with a greater reduction in BMI than placebo (weighted mean difference, -0.47 kg/m2; 95% CI, -0.62 to -0.31 kg/m2). The mean reduction in waist circumference with SGLT2 inhibitors versus placebo was 1.29 cm (95% CI, -2.62 to 0.04 cm), which was not statistically significant. There were no significant changes in fat mass, blood pressure, low-density lipoprotein cholesterol or high-density lipoprotein cholesterol with SGLT2 inhibitor treatment. CONCLUSION A meta-analysis demonstrated that although the weight lowering effect was mild, SGLT2 inhibitors significantly reduced body weight in obese patients without diabetes.

Abstract
AIMS To investigate the long-term effectiveness and safety of two distinct sodium-glucose co-transporter 2 (SGLT2) inhibitors, empagliflozin and dapagliflozin, in inadequately controlled type 2 diabetes (T2D) despite a combined administration of metformin, glimepiride and dipeptidyl peptidase-4 inhibitor. METHODS A total of 362 patients with T2D were enrolled for this 3-year open-label, prospective observational study. Empagliflozin (25 mg/day, n = 185) or dapagliflozin (10 mg/day, n = 177) was added to the existing triple drug regimen. HbA1c, fasting plasma glucose (FPG), body weight, and other cardiometabolic variables and adverse events were evaluated. RESULTS At 3 years, changes in HbA1c and FPG were -1.7% (standard error [SE] 0.10) and -60.0 mg/dL(2.2), and -1.1%(0.12) and -48.1 mg/dL(3.6), for empagliflozin and dapagliflozin group, respectively (P = 0.001 and P = 0.055). Empagliflozin group showed significantly greater body weight reduction (-4.5 kg [SE 0.35] vs. -1.0 kg [SE 0.40], P = 0.024) and had beneficial effects on HDL cholesterol and LDL cholesterol (both P < 0.05). The overall incidence of adverse events, cardiovascular events and mortality did not differ between the two groups. CONCLUSIONS Quadruple combination therapy with either empagliflozin or dapagliflozin showed a positive long-term effect in the glycemic control and body weight reduction with generally well tolerance. In general, the use of empagliflozin performed better than dapagliflozin. Clinical Trial Number NCT03748810 (ClinicalTrials.gov).

Abstract
INTRODUCTION In peritoneal dialysis (PD) patients, the peritoneal membrane is affected by glucose-based solutions used as peritoneal dialysate fluids. This exposure leads to changes of the membrane which may eventually culminate in fibrosis and method failure. In vitro or animal studies demonstrated that glucose transporters are upregulated upon exposure to these solutions. Expression studies of glucose transporters in human peritoneum have not been reported yet. METHODS Expression of SGLT-2, GLUT1, and GLUT3 in human peritoneal biopsies was analysed by real-time polymerase chain reaction (qPCR) and Western blot analysis. The localization of these glucose transporters in the peritoneum was evaluated by immunohistochemistry using a Histo-Score. RESULTS Peritoneal biopsies of patients (healthy controls, uremic, PD and encapsulating peritoneal sclerosis (EPS)) were analyzed. We found evidence of SGLT-2, GLUT1 and GLUT3 expression in the peritoneal membrane. Protein expression of SGLT-2 increases with PD-duration and is significantly enhanced in EPS patients. All transporters were predominantly, but not exclusively, located adjacent to the vessel walls of the peritoneal membrane. CONCLUSION Our study showed that SGLT-2, GLUT1 and GLUT3 were regularly expressed in the human peritoneum. SGLT-2 was particularly upregulated in PD patients with EPS, suggesting that this upregulation may be associated with pathological changes in the peritoneal membrane in this syndrome. Since preclinical studies in mice show that SGLT-2 inhibitors or downregulation of SGLT-2 ameliorated pathological changes in the peritoneum, SGLT-2 inhibitors may be potentially promising agents for therapy in PD patients that could reduce glucose absorption and delay functional deterioration of the peritoneal membrane in the long-term.

Abstract
Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism and insulin resistance. The dual sodium-glucose co-transporter 1/2 inhibitor (SGLT1/2i) licogliflozin (LIK066) ameliorates hyperinsulinism in patients with diabetes and obesity. This study examines the effect of licogliflozin on androgens in women with PCOS. In a multicentre, randomized, placebo-controlled, double-blind, 2-week trial, patients with PCOS received licogliflozin 50 mg or placebo three times a day (TID). Changes in free testosterone (FT), other androgens and variables of insulin resistance were analysed. Concentration of FT did not change (TRLIK066 :TRPCB [FT]: 0.88; 90% CI: 0.70-1.11; P = .353). Licogliflozin reduced androstendione (A4) by 19% (TRLIK066 :TRPCB [A4]: 0.81; 90% CI: 0.68-0.99; P = .089) and dehydroepiandrosteron sulphate (DHEAS) by 24% (TRLIK066 :TRPCB [DHEAS]: 0.76; 90% CI: 0.65-0.89; P = .008). Hyperinsulinaemia was reduced by 70% by licogliflozin (highest insulin concentration [MAXI]; TRLIK066 :TRPCB [MAXI]: 0·26; 90% CI:0.20-0.34; P < .001 and area under the curve insulin [AUCI]; TRLIK066 :TRPCB [AUCI]: 0.32; 90% CI: 0.25-0.41; P < .001). Diarrhoea and nausea occurred as common adverse events. Dual inhibition of SGLT1/2 ameliorates hyperinsulinaemia and hyperandrogenaemia in women with PCOS. Licogliflozin may represent a promising novel treatment option for PCOS.

Abstract
Sodium-glucose cotransporter type 2 inhibitors (SGLT2is) are new oral glucose-lowering agents that provide cardiovascular and renal protection in both patients with and without type 2 diabetes. Because of their unique mechanism of action, increased glucosuria is associated with osmotic diuresis and some natriuresis, yet the latter seems mostly transient. The potential role of the diuretic effect in overall cardiovascular and renal protection by SGLT2is remains a matter of debate. Precise evaluation of the diuretic effect is not so easy and most studies relied upon indirect estimations that led to divergent results, presumably also explained by different study designs and population characteristics. Everybody agrees upon the fact that SGLT2is are different from other classical diuretics (thiazides and loop diuretics) as they present some favourable properties, i.e. reduced sympathetic activity, preserved potassium balance, lower risk of acute renal injury, decrease of serum uric acid level. The potential role of the diuretic effect of SGLT2is on renal outcomes is still unclear, yet their ability to reduce albuminuria and dampen the risk of heart failure may contribute to improve renal prognosis besides other complex underlying mechanisms. In this comprehensive review we first critically analyse the results obtained with indirect methods that assess a diuretic effect of SGLT2is, second we describe the specificities of the diuretic activity of SGLT2is compared with other classical diuretics, and third we discuss the potential mechanisms by which the diuretic effect of SGLT2is could contribute to the improvement of renal outcomes consistently reported with this innovative amazing pharmacological class.

Abstract
INTRODUCTION The newer glucose-lowering therapies for type 2 diabetes (T2D), the glucagon-like peptide-1 receptor agonists (GLP1-RAs) and the sodium-glucose co-transporter 2 inhibitors (SGLT2i), have additional clinical benefits beyond improving glycaemic control; promoting weight loss, addressing associated cardiovascular risk factors and reducing macrovascular and microvascular complications. Considering their independent mechanisms of actions, there is a potential for significant synergy with combination therapy, yet limited data exist. This 32-week randomised, double-blind, placebo-controlled trial will gain mechanistic insight into the effects of coadministration of exenatide QW, a weekly subcutaneous GLP1-RA, with dapagliflozin, a once daily oral SGLT2i, on the dynamic, adaptive changes in energy balance, total, regional and organ-specific fat mass and multiorgan insulin sensitivity. METHODS AND ANALYSIS 110 obese patients with diagnosed T2D (glycated haemoglobin, HbA1c ≥48 mmol/mol) will be treated for 32 weeks with dapagliflozin (10 mg once daily either alone or in combination with exenatide QW (2 mg once weekly); active treatments will be compared with a control group (placebo tablet and sham injection). The primary objective of the study is to compare the adjusted mean reduction in total body fat mass (determined by dual-energy X-ray absorptiometry, DEXA) from baseline following 32 weeks of treatment with exenatide QW and dapagliflozin versus dapagliflozin alone compared with control (placebo). Secondary outcome measures include changes in (1) energy balance (energy intake and energy expenditure measured by indirect calorimetry); (2) appetite (between and within meals) and satiety quotient; (3) body composition including visceral adipose tissue, subcutaneous adipose tissue, liver and pancreatic fat. Exploratory outcome measures include metabolic changes in hepatic and peripheral insulin sensitivity (using a two-stage hyperinsulinaemic, euglycaemic clamp), central nervous system responses to food images using blood oxygen level-dependent (BOLD) functional MRI (fMRI) and changes in cardiovascular function (using transthoracic echocardiography, cardiac MR and duplex ultrasonography). ETHICS AND DISSEMINATION This study has been approved by the North West Liverpool Central Research Ethics Committee (14/NW/1147) and is conducted in accordance with the Declaration of Helsinki and the Good Clinical Practice. Results from the study will be published in peer-reviewed scientific and open access journals and/or presented at scientific conferences and summarised for distribution to the participants.

The Potential Roles of Osmotic and Nonosmotic Sodium Handling in Mediating the Effects of Sodium-Glucose Cotransporter 2 Inhibitors on Heart Failure. J Card Fail 2021; 27:1447-1455. [PMID: 34289398 PMCID: PMC8759453 DOI: 10.1016/j.cardfail.2021.07.003] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 06/08/2021] [Accepted: 07/02/2021] [Indexed: 11/24/2022]
Abstract
Concomitant type 2 diabetes and chronic kidney disease increases the risk of heart failure. Recent studies demonstrate beneficial effects of sodium-glucose cotransporter 2 (SGLT2) inhibitors on chronic kidney disease progression and heart failure hospitalization in patients with and without diabetes. In addition to inhibiting glucose reabsorption, SGLT2 inhibitors decrease proximal tubular sodium reabsorption, possibly leading to transient natriuresis. We review the hypothesis that SGLT2 inhibitor’s natriuretic and osmotic diuretic effects mediate their cardioprotective effects. The degree to which these benefits are related to changes in sodium, independent of the kidney, is currently unknown. Aside from effects on osmotically active sodium, we explore the intriguing possibility that SGLT2 inhibitors could also modulate nonosmotic sodium storage. This alternative hypothesis is based on emerging literature that challenges the traditional 2-compartment model of sodium balance to provide support for a 3-compartment model that includes the binding of sodium to glycosaminoglycans, such as those in muscles and skin. This recent research on nonosmotic sodium storage, as well as direct cardiac effects of SGLT2 inhibitors, provides possibilities for other ways in which SGLT2 inhibitors might mitigate heart failure risk. Overall, we review the effects of SGLT2 inhibitors on sodium balance and sensitivity, cardiac tissue, interstitial fluid and plasma volume, and nonosmotic sodium storage. SGLT2 inhibitors have cardiovascular benefits that include HF outcomes in patients with and without diabetes. Because the underlying mechanisms are only partly explained by improvements in BP, body weight, or glucose control, other mechanisms have been proposed. We focus here on a central role for effects on sodium as underlying the positive benefits of SGLT2 inhibitors in HF. We explore the new (although still unconfirmed) idea that SGLT2 inhibitors exert some of their positive effects by affecting nonosmotic sodium (ie, sodium bound to muscles and skin and not dissolved in the blood). SGLT2 inhibitors have emerged as a class of drugs, previously prescribed for patients with T2D, that have in more recent years been shown to have substantial heart and kidney clinical benefits in patients with and without T2D. The degree to which these benefits are related to kidney-independent changes in sodium homeostasis is currently unknown. A better understanding of the nonosmotic mechanisms underpinning the benefits of SGLT2 inhibition on HF (with reduced or preserved left ventricular ejection fraction) may allow researchers to assess the effects of SGLT2 inhibitors in combination with other treatments that affect sodium balance.

Abstract
BackgroundCardiovascular disease threatens the health and quality of life of individuals, particularly those with type II diabetes. Recently, some studies have reported the effect of sodium-glucose cotransporter 2 (SGLT2) inhibitors in reducing the rates of hospitalization or urgent visits, resulting in IV therapy for heart failure in patients with type 2 diabetes mellitus (T2DM).MethodsWe did a comprehensive search in electronic databases from inception through July 2020 for randomized-controlled trials, using the keywords “sodium-glucose cotransporter-2 inhibitor”, “dapagliflozin”, “heart failure”, “cardiovascular outcomes”, “major adverse cardiovascular events”, “all-cause mortality”, and “cardiovascular death”. Random-effects summary odds ratios (OR) were constructed using M-L heterogeneity model.ResultsFive trials with 5,252 patients were ultimately included. The incidence of hospitalization for heart failure (HHF) (n=4, OR=0.74; 95% CI, 0.61 to 0.88; I2 = 0%) and all-cause mortality (ACM, n=4, OR=0.76; 95% CI, 0.66 to 0.94; I2 = 0%); was reduced by dapagliflozin, respectively, in all heart failure patients, without obvious heterogeneity. The incidence of cardiovascular death in dapagliflozin was lower than that in placebo without statistically significant (CVD, n=5, OR=0.84; 95% CI, 0.69 to 1.03; I2 = 0%). In HFrEF subgroup, dapagliflozin was associated with a reduced incidence of hospitalization for heart failure (n=4, OR=0.74; 95% CI, 0.60 to 0.91; I2 = 0%), cardiovascular death (n=4, OR=0.72; 95% CI, 0.58 to 0.91; I2 = 8%), and all-cause mortality (n=3, OR=0.70; 95% CI, 0.50 to 0.99; I2 = 43%) without significant heterogeneity. In contrast, in the HFpEF subgroup, there was no difference in the incidence of cardiovascular death (n=2, OR=1.45; 95% CI, 0.95 to 2.22; I2 = 0%) and all-cause mortality (n=2, OR=1.04; 95% CI, 0.76 to 1.43; I2 = 0%) between dapagliflozin and placebo.ConclusionIn our study, dapagliflozin performed a statistical reduction in the rate of heart failure hospitalization, cardiovascular death, and all-cause mortality in patients with HFrEF and diabetes. However, in the HFpEF subgroup, dapagliflozin did not show a significant cardiovascular protective effect.

Abstract
Model-informed drug development (MIDD) is critical in all stages of the drug-development process and almost all regulatory submissions for new agents incorporate some form of modeling and simulation. This review describes the MIDD approaches used in the end-to-end development of ertugliflozin, a sodium-glucose cotransporter 2 inhibitor approved for the treatment of adults with type 2 diabetes mellitus. Approaches included (1) quantitative systems pharmacology modeling to predict dose-response relationships, (2) dose-response modeling and model-based meta-analysis for dose selection and efficacy comparisons, (3) population pharmacokinetics (PKs) modeling to characterize PKs and quantify population variability in PK parameters, (4) regression modeling to evaluate ertugliflozin dose-proportionality and the impact of uridine 5'-diphospho-glucuronosyltransferase (UGT) 1A9 genotype on ertugliflozin PKs, and (5) physiologically-based PK modeling to assess the risk of UGT-mediated drug-drug interactions. These end-to-end MIDD approaches for ertugliflozin facilitated decision making, resulted in time/cost savings, and supported registration and labeling.

Abstract
As an active pharmaceutical ingredient, dapagliflozin propanediol monohydrate (D-PD) has been used in the solvated form consisting of dapagliflozin compounded with (S)-propylene glycol and monohydrate at a 1:1:1 ratio. However, dapagliflozin propanediol loses the solvent's reduced lattice structure at slightly higher temperatures. Due to its sensitive solid-state stability, the temperature and humidity are strictly controlled during the production and storage of dapagliflozin. Thus, crystalline molecular complexes containing pharmaceutical salts, solvates, monohydrates, and cocrystals have recently been developed as alternative strategies. This study investigated the dapagliflozin free base (D-FB), D-PD, and dapagliflozin l-proline cocrystals (D-LP). Their solid-state behavior was also evaluated in stress stability studies. The compounds were analyzed using scanning electron microscopy (SEM), powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), Fourier-transform infrared (FT-IR) spectroscopy, dynamic vapor sorption (DVS), and powder rheology testing. In addition, Carr's index, the Hausner ratio, contact angle, and intrinsic dissolution rate were calculated. Dapagliflozin exhibited distinct physical properties depending upon the differences in solid form and also showed significant differences in solid-state behavior in the stress stability test. In conclusion, D-LP was superior to D-FB or D-PD in physicochemical and mechanical properties.

Abstract
AIM To investigate the glucosuric, renal and haemodynamic effects of licogliflozin, a dual sodium-glucose co-transporter-1 and sodium-glucose co-transporter-2 inhibitor, in patients with chronic kidney disease (CKD). METHODS This multiple-dose, parallel-group, phase II mechanistic study randomized 53 participants (aged 18-78 years, body mass index ≤ 50 kg/m2 ) with varying degrees of CKD or normal renal function to treatment with licogliflozin (50 mg once daily) or placebo for 7 days. The effects of licogliflozin on 24-h urinary glucose excretion (UGE24 ), renal function, haemodynamics, pharmacokinetics and safety were assessed. RESULTS Licogliflozin treatment for 7 days significantly (p < .01) increased UGE24 from baseline in participants with normal renal function (adjusted mean change: 41.8 [33.6, 49.9] g) or with mild (32.6 [24.1, 41.0] g), moderate A (35.7 [28.6, 42.9] g) or moderate B (20.3 [13.1, 27.5] g) CKD, but not in severe (6.2 [-0.71, 13.18] g) CKD. Licogliflozin reduced urinary electrolytes (sodium, potassium and chloride), blood pressure and urinary volume to varying extents among different groups. Significant increases in renin (p < .05), angiotensin II (p < .05) and aldosterone (p < .01) levels were observed. Adverse events were generally mild, and most commonly included diarrhoea (94%), flatulence (68%) and abdominal pain (21%). CONCLUSION Licogliflozin treatment results in significantly increased UGE and favourable changes in urinary electrolytes and haemodynamics in patients with varying degrees of CKD (estimated glomerular filtration rate ≥ 45 mL/min/1.73 m2 ).

Abstract
Diabetes mellitus is a major cause of chronic kidney disease and end-stage renal disease. However, the management of chronic kidney disease, particularly diabetes, requires vast improvements. Recently, sodium-glucose cotransporter-2 (SGLT2) inhibitors, originally developed for the treatment of diabetes, have been shown to protect against kidney injury via glycemic control, as well as various other mechanisms, including blood pressure and hemodynamic regulation, protection from lipotoxicity, and uric acid control. As such, regulation of these mechanisms is recommended as an effective multidisciplinary approach for the treatment of diabetic patients with kidney disease. Thus, SGLT2 inhibitors are expected to become key drugs for treating diabetic kidney disease. This review summarizes the recent clinical evidence pertaining to SGLT2 inhibitors as well as the mechanisms underlying their renoprotective effects. Hence, the information contained herein will advance the current understanding regarding the pleiotropic effects of SGLT2 inhibitors, while promoting future research in the field.

Cardiovascular benefits of sodium-glucose cotransporter 2 inhibitors in diabetic and nondiabetic patients. Cardiovasc Diabetol 2021; 20:78.

Abstract
Sodium-glucose cotransporter 2 inhibitors (SGLT2i) were developed as antidiabetic agents, but accumulating evidence has shown their beneficial effects on the cardiovascular system. Analyses of the EMPA-REG OUTCOME trial (Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients) suggested that these benefits are independent of glycemic control. Several large-scale outcome trials of SGLT2i also showed cardiovascular benefits in nondiabetic patients, strengthening this perspective. Extensive animal and clinical studies have likewise shown that mechanisms other than the antihyperglycemic effect underlie the cardiovascular benefits. Recent clinical guidelines recommend the use of SGLT2i in patients with type 2 diabetes mellitus and cardiovascular diseases because of the proven cardiovascular protective effects. Since the cardiovascular benefits are independent of glycemic control, the therapeutic spectrum of SGLT2i will likely be extended to nondiabetic patients.

Abstract
AIMS To develop a quantitative systems pharmacology model to describe the effect of dapagliflozin (a sodium-glucose co-transporter-2 [SGLT2] inhibitor) on glucose-insulin dynamics in type 2 diabetes mellitus (T2DM) patients, and to identify key determinants of treatment-mediated glycated haemoglobin (HbA1c) reduction. MATERIALS AND METHODS Glycaemic control during dapagliflozin treatment was mechanistically characterized by integrating components representing dapagliflozin pharmacokinetics (PK), glucose-insulin homeostasis, renal glucose reabsorption, and HbA1c formation. The model was developed using PK variables, glucose, plasma insulin, and urinary glucose excretion (UGE) from a phase IIa dapagliflozin trial in patients with T2DM (NCT00162305). The model was used to predict dapagliflozin-induced HbA1c reduction; model predictions were compared to actual data from phase III trials (NCT00528879, NCT00683878, NCT00680745 and NCT00673231). RESULTS The integrated glucose-insulin-dapagliflozin model successfully described plasma glucose and insulin levels, as well as UGE in response to oral glucose tolerance tests and meal intake. HbA1c reduction was also well predicted. The results show that dapagliflozin-mediated glycaemic control is anticorrelated to steady-state insulin concentration and insulin sensitivity. CONCLUSIONS The developed model framework is the first to integrate SGLT2 inhibitor mechanism of action with both short-term glucose-insulin dynamics and long-term glucose control (HbA1c). The results suggest that dapagliflozin treatment is beneficial in patients with inadequate glycaemic control from insulin alone and this benefit increases as insulin control diminishes.

Abstract
Sodium glucose cotransporter-2 (SGLT-2) inhibitor has been reported to exert a glucose-lowering effect in the peritoneum exposed to peritoneal dialysis solution. However, whether SGLT-2 inhibitors can regulate peritoneal fibrosis by suppressing TGF-β/Smad signaling is unclear. We aimed to (i) examine the effect of the SGLT-2 inhibitor empagliflozin in reducing inflammatory reaction and preventing peritoneal dialysis solution-induced peritoneal fibrosis and (ii) elucidate the underlying mechanisms. High-glucose peritoneal dialysis solution or transforming growth factor β1 (TGF-β1) was used to induce peritoneal fibrosis in vivo, in a mouse peritoneal dialysis model (C57BL/6 mice) and in human peritoneal mesothelial cells in vitro, to stimulate extracellular matrix accumulation. The effects of empagliflozin and adeno-associated virus-RNAi, which is used to suppress SGLT-2 activity, on peritoneal fibrosis and extracellular matrix were evaluated. The mice that received chronic peritoneal dialysis solution infusions showed typical features of peritoneal fibrosis, including markedly increased peritoneal thickness, excessive matrix deposition, increased peritoneal permeability, and upregulated α-smooth muscle actin and collagen I expression. Empagliflozin treatment or downregulation of SGLT-2 expression significantly ameliorated these pathological changes. Inflammatory cytokines (TNF-α, IL-1β, IL-6) and TGF-β/Smad signaling-associated proteins, such as TGF-β1 and phosphorylated Smad (p-Smad3), decreased in the empagliflozin-treated and SGLT-2 downregulated groups. In addition, empagliflozin treatment and downregulation of SGLT-2 expression reduced the levels of inflammatory cytokines (TNF-α, IL-1β, IL-6), TGF-β1, α-smooth muscle actin, collagen I, and p-Smad3 accumulation in human peritoneal mesothelial cells. Collectively, these results indicated that empagliflozin exerted a clear protective effect on high-glucose peritoneal dialysis-induced peritoneal fibrosis via suppressing TGF-β/Smad signaling.

Abstract
Background. Over the last few years, the use of sodium-glucose cotransporter 2 inhibitors (SGLT2i) and glucagon-like peptide 1 receptor agonists (GLP-1RA) has increased substantially in medical practice due to their documented benefits in cardiorenal and metabolic health. In this sense, and in addition to being used for glycemic control in diabetic patients, these drugs also have other favorable effects such as weight loss and lowering blood pressure, and more recently, they have been shown to have cardio and renoprotective effects with anti-inflammatory properties. Concerning the latter, the individual or associated use of these antihyperglycemic agents has been linked with a decrease in proinflammatory cytokines and with an improvement in the inflammatory profile in chronic endocrine-metabolic diseases. Hence, these drugs have been positioned as first-line therapy in the management of diabetes and its multiple comorbidities, such as obesity, which has been associated with persistent inflammatory states that induce dysfunction of the adipose tissue. Moreover, other frequent comorbidities in long-standing diabetic patients are chronic complications such as diabetic kidney disease, whose progression can be slowed by SGLT2i and/or GLP-1RA. The neuroendocrine and immunometabolism mechanisms underlying adipose tissue inflammation in individuals with diabetes and cardiometabolic and renal diseases are complex and not fully understood. Summary. This review intends to expose the probable molecular mechanisms and compile evidence of the synergistic or additive anti-inflammatory effects of SGLT2i and GLP-1RA and their potential impact on the management of patients with obesity and cardiorenal compromise.

Abstract
OBJECTIVE Previous evidence suggested that sodium-glucose cotransporter 2 inhibitor (SGLT2i)-mediated urinary glucose excretion (UGE) appeared to be reduced with a decrease in glomerular filtration rate. Thus, we conducted a systematic review and meta-analysis to compare SGLT2i-mediated UGE among individuals with different levels of renal function. METHODS We conducted systematic searches in PubMed, Medline, Embase, Cochrane Central Register of Controlled Trials, and ClinicalTrial.gov from inception to May 2021. Clinical studies of SGLT2i with reports of UGE changes in predefined different levels of renal function were included. The results were expressed as pooled effect sizes with 95% confidence interval (CI). A random-effects model was used to calculate the pooled effect sizes. RESULTS In total, eight eligible studies were included. Significant differences were observed in the post-treatment UGE level among subgroups stratified by renal function (P <0.001 for subgroup difference), which were gradually decreased along with the severity of impaired renal function. Consistently, changes in UGE before and after SGLT2i treatment were also decreased along with the severity of impaired renal function [67.52 g/day (95%CI: 55.58 to 79.47 g/day) for individuals with normal renal function, 52.41 g/day (95%CI: 38.83 to 65.99 g/day) for individuals with mild renal function impairment, 35.11 g/day (95%CI: 19.79 to 50.43 g/day) for individuals with moderate renal function impairment, and 13.53 g/day (95%CI: 7.20 to 19.86 g/day) for individuals with severe renal function impairment; P <0.001 for subgroup differences]. CONCLUSIONS SGLT2i-mediated UGE was renal function dependent, which was decreased with the extent of renal function impairment.

Abstract
AIMS To evaluate the pharmacokinetic (PK) and pharmacodynamic (PD) characteristics, and tolerability of janagliflozin, a novel sodium-glucose co-transporter-2 inhibitor, in Chinese people with type 2 diabetes mellitus (T2DM). MATERIALS AND METHODS In this study, 36 people with T2DM were randomly assigned in a 1:1:1:1 ratio to receive janagliflozin 25 mg, janagliflozin 50 mg, dapagliflozin 10 mg or placebo. Participants received a single dose on day 1, and were treated once daily from day 4 to day 17. RESULTS Following oral administration, janagliflozin was rapidly absorbed, reaching Cmax at 2 hours. The mean half-life (t1/2 ) at steady state was approximately 21 to 23 hours. There was no significant accumulation with multiple doses (accumulation factor < 2). In participants treated with janagliflozin 25 mg, janagliflozin 50 mg, dapagliflozin 10 mg or placebo, change in mean 24-hour urinary glucose excretion from baseline was 92.35, 94.17, 87.61 and 6.26 g after multiple doses, and change in mean fasting plasma glucose level from baseline to day 17 was -2.18, -2.66, -2.79 and 1.70%, respectively. Most adverse events (AEs) were mild or moderate with no deaths, serious AEs, or discontinuations due to AEs. CONCLUSIONS Single and multiple oral administration (14 days) of janagliflozin 25 mg and 50 mg exhibited favourable PK, PD and tolerability profiles in Chinese people with T2DM, which were comparable to those of dapagliflozin 10 mg. Janagliflozin 25 mg and 50 mg are recommended for further clinical investigation.

Abstract
The liver is not the exclusive site of glucose production in humans in the postabsorptive state. Robust data support that the kidney is capable of gluconeogenesis and studies have demonstrated that renal glucose production can increase systemic glucose production. The kidney has a role in maintaining glucose body balance, not only as an organ for gluconeogenesis but by using glucose as a metabolic substrate. The kidneys reabsorb filtered glucose through the sodium‐glucose cotransporters sodium‐glucose cotransporter (SGLT) 1 and SGLT2, which are localized on the brush border membrane of the early proximal tubule with immune detection of their expression in the tubularized Bowman capsule. In patients with diabetes mellitus, the renal maximum glucose reabsorptive capacity, and the threshold for glucose passage into the urine, are higher and contribute to the hyperglycemic state. The administration of SGLT2 inhibitors to patients with diabetes mellitus enhances sodium and glucose excretion, leading to a reduction of the glycosuria threshold and tubular maximal transport of glucose. The net effects of SGLT2 inhibition are to drive a reduction in plasma glucose levels, improving insulin secretion and sensitivity. The benefit of SGLT2 inhibitors goes beyond glycemic control, since inhibition of renal glucose reabsorption affects blood pressure and improves the hemodynamic profile and the tubule glomerular feedback. This action acts to rebalance the dense macula response by restoring adenosine production and restraining renin‐angiotensin‐aldosterone activation. By improving renal and cardiovascular function, we explain the impressive reduction in adverse outcomes associated with heart failure supporting the current clinical perspective.

Abstract
AIMS Dapagliflozin is a sodium-glucose co-transporter 2 inhibitor that has been developed as oral glucose lowering drug. The original dosefinding studies focused on optimal glycaemic effects. However, dapagliflozin also affects various cardiorenal risk markers and provides cardiorenal protection. To evaluate whether the currently registered doses of 5 and 10 mg are optimal for cardiorenal efficacy and safety, we characterized the relationship between dapagliflozin exposure and nonglycaemic cardiorenal risk markers as well as adverse events. METHODS Data were obtained from a pooled database of 13 24-week randomized controlled clinical trials of the clinical development programme of dapagliflozin. The exposure-response relationship was quantified using population pharmacodynamic and repeated time-to-event models. RESULTS A dose of 10 mg dapagliflozin resulted in an average individual exposure of 638 ng h/mL (95% prediction interval [PI]: 354-1061 ng h/mL), which translated to 71.2% (95% PI: 57.9-80.5%), 61.1% (95% PI: 58.0-64.8%), 91.3% (95% PI: 85.4-94.6%) and 25.7% (95% PI: 23.5-28.3%) of its estimated maximum effect for fasting plasma glucose, haematocrit, serum creatinine and urinary albumin-creatinine ratio, respectively. CONCLUSION We demonstrate that doses higher than 10 mg could provide additional beneficial effects in haematocrit, systolic blood pressure, urinary albumin-creatinine ratio and uric acid, without obvious increases in the rate of adverse events. These results raise the question whether future outcome studies assessing the benefits of higher than currently registered dapagliflozin doses are merited.

Abstract
The European Society of Cardiology recently addressed the use of SGLT2 inhibitor use in the treatment of heart failure (HF). Dapagliflozin is a SGLT2 inhibitor recently approved by the US FDA for treatment of patients with HF with a reduced ejection fraction with a New York Heart Association classification of II-IV. Dapagliflozin significantly decreases the risk of worsening HF or death from cardiovascular cause compared with placebo and this risk does not differ based on the presence or absence of Type 2 diabetes. This paper aims to summarize the chemistry, pharmacodynamics and pharmacokinetics of dapagliflozin; and evaluates the clinical efficacy of dapagliflozin in the treatment of HF.

Abstract
The prevalence of diabetes and its related complications are increasing significantly globally. Collected evidence suggested that several genetic and environmental factors contribute to diabetes mellitus. Associated complications such as retinopathy, neuropathy, nephropathy and other cardiovascular complications are a direct result of diabetes. Epigenetic factors include deoxyribonucleic acid (DNA) methylation and histone post-translational modifications. These factors are directly related with pathological factors such as oxidative stress, generation of inflammatory mediators and hyperglycemia. These result in altered gene expression and targets cells in the pathology of diabetes mellitus without specific changes in a DNA sequence. Environmental factors and malnutrition are equally responsible for epigenetic states. Accumulated evidence suggested that environmental stimuli alter the gene expression that result in epigenetic changes in chromatin. Recent studies proposed that epigenetics may include the occurrence of 'metabolic memory' found in animal studies. Further study into epigenetic mechanism might give us new vision into the pathogenesis of diabetes mellitus and related complication thus leading to the discovery of new therapeutic targets. In this review, we discuss the possible epigenetic changes and mechanism that happen in diabetes mellitus type 1 and type 2 separately. We highlight the important epigenetic and non-epigenetic therapeutic targets involved in the management of diabetes and associated complications.
