Abstract
Aflatoxins are harmful natural contaminants found in foods and are known to be hepatotoxic. However, recent studies have linked chronic consumption of aflatoxins to nephrotoxicity in both animals and humans. Here, we conducted a systematic review of active compounds, crude extracts, herbal formulations, and probiotics against aflatoxin-induced renal dysfunction, highlighting their mechanisms of action in both in vitro and in vivo studies. The natural products and dietary supplements discussed in this study alleviated aflatoxin-induced renal oxidative stress, inflammation, tissue damage, and markers of renal function, mostly in animal models. Therefore, the information provided in this review may improve the management of kidney disease associated with aflatoxin exposure and potentially aid in animal feed supplementation. However, future research is warranted to translate the outcomes of this study into clinical use in kidney patients.

Abstract
Background This was a prospective randomized controlled trial in 200 cases presented with endometrial cavity fluid at the day of oocyte retrieval at a private fertility center from 2013 to 2021. The cases were randomized at day of ovum pickup into 2 groups: Group 1 (control group) (n = 100): conventional management with follow-up and reassessment by transvaginal ultrasound on day 5. Group 2 (interventional group) (n = 100): aspiration of the fluid was done and cases were given diosmin 500 mg 3 times per day till reassessment at embryo transfer day. In both groups, we proceeded with fresh embryo transfer if no fluid is present on day 5 or freeze-all policy if persistent fluid was detected. Results Endometrial fluid on the 5th day was significantly higher in the control group (28.0%) than in the interventional group (6.0%) (P < 0.001). Regarding pregnancy rate, although being higher in the interventional group (54.3% vs 50.0%), the difference was not statistically significant (P = 0.5). It was found that the intervention was associated with risk reduction of endometrial fluid (OR = 0.168, 95% CI = 0.065-0.429, P < 0.001. Conclusion Aspiration of endometrial cavity fluid with diosmin intake increased the likelihood of fresh embryo transfer and with a slightly better pregnancy rate compared to conservative management.Clinical trial number: NCT02158000, Date of registration: 6/6/2014, Date of initial enrollment (first patient recruiting): 1/11/2014, URL: https://clinicaltrials.gov/ct2/show/NCT02158000.

Abstract
Secondary osteoporosis is commonly caused by long-term intake of glucocorticoids (GCs), such as dexamethasone (DEX). Diosmin, a natural substance with potent antioxidant and anti-inflammatory properties, is clinically used for treating some vascular disorders. The current work targeted exploring the protective properties of diosmin to counteract DEX-induced osteoporosis in vivo. Rats were administered DEX (7 mg/kg) once weekly for 5 weeks, and in the second week, vehicle or diosmin (50 or 100 mg/kg/day) for the next four weeks. Femur bone tissues were collected and processed for histological and biochemical examinations. The study findings showed that diosmin alleviated the histological bone impairments caused by DEX. In addition, diosmin upregulated the expression of Runt-related transcription factor 2 (Runx2) and phosphorylated protein kinase B (p-AKT) and the mRNA transcripts of Wingless (Wnt) and osteocalcin. Furthermore, diosmin counteracted the rise in the mRNA levels of receptor activator of nuclear factor-kB ligand (RANKL) and the reduction in osteoprotegerin (OPG), both were induced by DEX. Diosmin restored the oxidant/antioxidant equilibrium and exerted significant antiapoptotic activity. The aforementioned effects were more pronounced at the dose level of 100 mg/kg. Collectively, diosmin has proven to protect rats against DEX-induced osteoporosis by augmenting osteoblast and bone development while hindering osteoclast and bone resorption. Our findings could be used as a stand for recommending supplementation of diosmin for patients chronically using GCs.

Abstract
In diabetes, chronic hyperglycemia, dyslipidemia, inflammation and oxidative stress contribute to the progression of macro/microvascular complications. Recently, benefits of the use of flavonoids in these conditions have been established. This study investigates, in two different mouse models of diabetes, the vasculoprotective effects of the synthetic flavonoid hidrosmin on endothelial dysfunction and atherogenesis. In a type 2 diabetes model of leptin-receptor-deficient (db/db) mice, orally administered hidrosmin (600 mg/kg/day) for 16 weeks markedly improved vascular function in aorta and mesenteric arteries without affecting vascular structural properties, as assessed by wire and pressure myography. In streptozotocin-induced type 1 diabetic apolipoprotein E-deficient mice, hidrosmin treatment for 7 weeks reduced atherosclerotic plaque size and lipid content; increased markers of plaque stability; and decreased markers of inflammation, senescence and oxidative stress in aorta. Hidrosmin showed cardiovascular safety, as neither functional nor structural abnormalities were noted in diabetic hearts. Ex vivo, hidrosmin induced vascular relaxation that was blocked by nitric oxide synthase (NOS) inhibition. In vitro, hidrosmin stimulated endothelial NOS activity and NO production and downregulated hyperglycemia-induced inflammatory and oxidant genes in vascular smooth muscle cells. Our results highlight hidrosmin as a potential add-on therapy in the treatment of macrovascular complications of diabetes.

Abstract
The endothelium, a crucial homeostatic organ, regulates vascular permeability and tone. Under physiological conditions, endothelial stimulation induces vasodilator endothelial nitric oxide (eNO) release and prevents adhesion molecule accessibility and leukocyte adhesion and migration into vessel walls. Endothelium dysfunction is a principal event in cardiovascular disorders, including atherosclerosis. Minimal attention is given to an important endothelial cell structure, the endothelial glycocalyx (GCX), a negatively charged heterogeneous polysaccharide that serves as a protective covering for endothelial cells and enables endothelial cells to transduce mechanical stimuli into various biological and chemical activities. Endothelial GCX shedding thus plays a role in endothelial dysfunction, for example by increasing vascular permeability and decreasing vessel tone. Consequently, there is increasing interest in developing therapies that focus on GCX repair to limit downstream endothelium dysfunction and prevent further downstream cardiovascular events. Here, we present diosmin (3',5,7-trihydroxy-4'-methoxyflavone-7-rhamnoglucoside), a flavone glycoside of diosmetin, which downregulates adhesive molecule expression, decreases inflammation and capillary permeability, and upregulates eNO expression. Due to these pleiotropic effects of diosmin on the vasculature, a possible unidentified mechanism of action is through GCX restoration. We hypothesize that diosmin positively affects GCX integrity along with GCX-related endothelial functions. Our hypothesis was tested in a partial ligation left carotid artery (LCA) mouse model, where the right carotid artery was the control for each mouse. Diosmin (50 mg/kg) was administered daily for 7 days, 72 h after ligation. Within the ligated mice LCAs, diosmin treatment elevated the activated eNO synthase level, inhibited inflammatory cell uptake, decreased vessel wall thickness, increased vessel diameter, and increased GCX coverage of the vessel wall. ELISA showed a decrease in hyaluronan concentration in plasma samples of diosmin-treated mice, signifying reduced GCX shedding. In summary, diosmin supported endothelial GCX integrity, to which we attribute diosmin's preservation of endothelial function as indicated by attenuated expression of inflammatory factors and restored vascular tone.

Optimization of Lipid Nanoparticles by Response Surface Methodology to Improve the Ocular Delivery of Diosmin: Characterization and In-Vitro Anti-Inflammatory Assessment. Pharmaceutics 2022; 14:pharmaceutics14091961.

Abstract
Diosmin is a flavonoid with a great variety of biological activities including antioxidant and anti-inflammatory ones. Its cytoprotective effect in retinal pigment epithelium cells under high glucose conditions makes it a potential support in the treatment of diabetic retinopathy. Despite its benefits, poor solubility in water reduces its potential for therapeutic use, making it the biggest biopharmaceutical challenge. The design of diosmin-loaded nanocarriers for topical ophthalmic application represents a novelty that has not been yet explored. For this purpose, the response surface methodology (RSM) was used to optimize nanostructured lipid carriers (NLCs), compatible for ocular administration, to encapsulate diosmin and improve its physicochemical issues. NLCs were prepared by a simple and scalable technique: a melt emulsification method followed by ultrasonication. The experimental design was composed of four independent variables (solid lipid concentration, liquid lipid concentration, surfactant concentration and type of solid lipid). The effect of the factors was assessed on NLC size and PDI (responses) by analysis of variance (ANOVA). The optimized formulation was selected according to the desirability function (0.993). Diosmin at two different concentrations (80 and 160 µM) was encapsulated into NLCs. Drug-loaded nanocarriers (D-NLCs) were subjected to a physicochemical and technological investigation revealing a mean particle size of 83.58 ± 0.77 nm and 82.21 ± 1.12 nm, respectively for the D-NLC formulation prepared with diosmin at the concentration of 80 µM or 160 µM, and a net negative surface charge (−18.5 ± 0.60 and −18.0 ± 1.18, respectively for the two batches). The formulations were analyzed in terms of pH (6.5), viscosity, and adjusted for osmolarity, making them more compatible with the ocular environment. Subsequently, stability studies were carried out to assess D-NLC behavior under different storage conditions up to 60 days, indicating a good stability of NLC samples at room temperature. In-vitro studies on ARPE-19 cells confirmed the cytocompatibility of NLCs with retinal epithelium. The effect of D-NLCs was also evaluated in-vitro on a model of retinal inflammation, demonstrating the cytoprotective effect of D-NLCs at various concentrations. RSM was found to be a reliable model to optimize NLCs for diosmin encapsulation.

Abstract
Plant-derived flavonoids have been the focus of research for many years mainly in the last decade owing to their therapeutic properties. So far, about 4000 flavonoids have been identified from plants and diosmin (a flavone glycoside) is one of them. Online databases, previous studies, and reviews have been used to gather information on anti-oxidant, immunomodulatory, anti-cancer, anti-parasitic, and anti-microbialproperties of diosmin. Effects of diosmin in combination with other flavonoids have been reviewed thoroughly and its administrative routes are also summarized. Additionally, we studied the effect of diosmin on critical protein networks. It exhibits therapeutic effects in diabetes and its associated complications such as neuropathy and dyslipidemia. Combination of diosmin with hesperidin is found to be very effective in the treatment of chronic venous insufficiency and haemorrhoids. Diosmin is an exquisite therapeutic agent alone as well as in combination with other flavonoids.

Abstract
BACKGROUND Hypertension is a major global health problem. It is a major risk factor of cardiovascular disease. One of the most used experimental models in studying antihypertensive action is the deoxycorticosterone acetate (DOCA)-salt hypertensive rat. This study aimed to investigate the cardiovascular protective effect of astaxanthin (ASX) in DOCA-salt-induced hypertension and its possible underlying mechanisms. METHODS A total of 48 adult male Wistar albino rats were divided into three groups: control, DOCA, and DOCA + ASX. Blood pressure, serum cardiac enzyme levels, some oxidative stress and inflammatory biomarker levels, and lipid profile levels were measured. The weight of the left ventricle to tibial length ratio was calculated. Apoptosis detection and total genomic DNA extraction in aortic and cardiac tissues were investigated. The apoptotic marker BAX was also immunohistochemically assessed in the heart and aorta. RESULTS Compared to the control group, the DOCA group was associated with a significant increase in blood pressure, serum cardiac enzyme levels, oxidative stress and inflammatory biomarker levels, lipid profile except serum high-density lipoprotein (HDL), weight of the left ventricle to tibial length, and total released DNA fragmentation level of the left ventricle and aorta and a significant decrease in reduced glutathione (GSH) and HDL. Compared to the DOCA group, the DOCA + ASX group significantly improved the DOCA-induced changes. CONCLUSION ASX has beneficial protective effects on DOCA-salt-induced hypertension via DNA fragmentation protection, apoptosis inhibition, antioxidant, anti-inflammatory, and its effects on lipid levels.

Abstract
Vascular dementia (VaD) is the second most prevalent type of dementia characterized by progressive cognitive deficits and is a major risk factor for the development of Alzheimer's disease and other neurodegenerative disorders. This study is aimed at determining the potential neuroprotective effect of sitagliptin (STG) on cognitive deficits in L-methionine-induced VaD in rats and the possible underlying mechanisms. 30 adult male Wistar albino rats were divided equally (n = 10) into three groups: control, VaD, and VaD + STG groups. The cognitive performance of the animals was conducted by open field, elevated plus maze, Y-maze, novel object recognition, and Morris water maze tests. Serum homocysteine, TNF-α, IL-6, IL-10, total cholesterol, and triglycerides levels were assessed together with hippocampal MDA, SOD, and BDNF. Histopathological and immunohistochemical assessments of the thoracic aorta and hippocampus (CA1 region) were also performed. Chronic L-methionine administration impaired memory and learning and induced anxiety. On the other hand, STG protected against cognitive deficits through improving oxidative stress biomarkers, inflammatory mediators, lipid profiles, and hippocampus level of BDNF as well as decreasing caspase-3 and GFAP and increasing Ki-67 immunoreactions in the hippocampus. Also, STG improved the endothelial dysfunction via upregulation of aortic eNOS immunoreaction. STG improved the cognitive deficits of L-methionine-induced VaD by its antioxidant, anti-inflammatory, antiapoptotic, and neurotrophic effects. These findings suggest that STG may be a promising future agent for protection against VaD.

[PMID: 34738632 DOI: 10.3892/or.2021.8215] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2021] [Accepted: 08/09/2021] [Indexed: 11/05/2022] Open
Abstract
Colon cancer is one of the most commonly diagnosed malignancies, which begins as a polyp and grows to become cancer. Diosmin (DS) and naringenin (NR) are naturally occurring flavonoids that exhibit various pharmacological activities. Although several studies have illustrated the effectiveness of these flavonoids as anti‑cancerous agents individually, the combinatorial impact of these compounds has not been explored. In the present study, the combined effect of DS and NR (DiNar) in colon cancer cell lines HCT116 and SW480 were assessed by targeting apoptosis and inflammatory pathways. The MTT assay was used to evaluate the effect of DiNar on cell proliferation, while Chou‑Talalay analysis was employed to determine the combination index of DS and NR. Moreover, flow cytometry was used to monitor cell cycle arrest and population study. The onset of apoptosis was assessed by DAPI staining, DNA fragmentation, and Annexin V‑fluorescein isothiocyanate/propidium iodide (Annexin V‑FITC/PI). The expression levels of apoptotic pathway markers, Bcl‑2, Bax, caspase3, caspase8, caspase9 and p53, and inflammatory markers, NF‑κβ, IKK‑α and IKK‑β, were assessed using western blotting and reverse transcription‑quantitative PCR. These results suggested that DiNar treatment acts synergistically and induces cytotoxicity with a concomitant increase in chromatin condensation, DNA fragmentation and cell cycle arrest in the G0/G1 phase. Annexin V‑FITC/PI apoptosis assay also showed increased number of cells undergoing apoptosis in the DiNar treatment group. Furthermore, the expression of apoptosis and inflammatory markers was also more effectively regulated under the DiNar treatment. Thereby, these findings demonstrated that DiNar treatment could be a potential novel chemotherapeutic alternative in colon cancer.

Abstract
With the coming of the era of the aging population, hypertension has become a global health burden to be dealt with. Although there are multiple drugs and procedures to control the symptoms of hypertension, the management of it is still a long-term process, and the side effects of conventional drugs pose a burden on patients. Flavonoids, common compounds found in fruits and vegetables as secondary metabolites, are active components in Chinese Herbal Medicine. The flavonoids are proved to have cardiovascular benefits based on a plethora of animal experiments over the last decade. Thus, the flavonoids or flavonoid-rich plant extracts endowed with anti-hypertension activities and probable mechanisms were reviewed. It has been found that flavonoids may affect blood pressure in various ways. Moreover, despite the substantial evidence of the potential for flavonoids in the control of hypertension, it is not sufficient to support the clinical application of flavonoids as an adjuvant or core drug. So the synergistic effects of flavonoids with other drugs, pharmacokinetic studies, clinical trials and the safety of flavonoids are also incorporated in the discussion. It is believed that more breakthrough studies are needed. Overall, this review may shed some new light on the explicit recognition of the mechanisms of anti-hypertension actions of flavonoids, pointing out the limitations of relevant research at the current stage and the aspects that should be strengthened in future researches.

Abstract
BACKGROUND There is a necessity to develop or discover an alternative drug to combat the drug resistance by Giardia duodenalis and minimize the multiple doses and frequency of the conventional drug administration. Progressive repositioning or 'repurposing' of drugs has become widespread due to economic circumstances and medical emergency needs. Daflon 500 mg (DFL) is a natural product used safely as a nutrient supplement and an antidiabetic drug in many European countries and the US. OBJECTIVE This study aimed at investigating the efficiency of DFL, in vivo, in a murine model as a safe alternative or co-drug for giardiasis. MATERIALS AND METHODS Swiss Albino mice (n = 32) were inoculated with 1X104Giardia cysts and assigned to four groups: One group was the infected non-treated control mice and three experimental groups that were treated differently, either with Metronidazole (MTZ), DFL, or combined therapy of DFL/MTZ. Also, eight normal mice served as a control group. All mice were sacrificed 13 days post-infection for the parasitic, histopathological, and oxidative stress analysis. RESULTS MTZ, DFL, and the combined therapy significantly reduced the number of trophozoites and cysts compared to their counterparts of the infected mice. The histopathological analysis of the small intestines of the mice treated with the combined therapy retained typical intestinal architecture and normal levels of malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione. CONCLUSION This study indicated promising actions of Daflon 500 as an anti-giardial drug, and the results demonstrated its potential effect in improving the intestinal epithelial tissue and disturbing the Giardia stages when it was taken collectively with Metronidazole.

Abstract
Dox induces kidney damage. Dox leads to a decrease in antioxidant defense mechanism. Diosmin administration restores antioxidant properties.
Doxorubicin (Dox) is an anthracycline antibiotic that is primarily used for treating various solid tumors including that of pulmonary, ovary, breast, uterine, cervix, and several blood cancers. However, nephrotoxicity associated with Dox treatment limits its clinical use. Administration of Dox in combination with compounds exhibiting antioxidant properties are being used to minimize the side effects of Dox. Diosmin is a flavonoid glycoside with numerous beneficial properties that is found in the pericarp of many citrus fruits. Diosmin has demonstrated antioxidant, anti-inflammatory, and anti-apoptotic effects in response to various insults, although the exact mechanism remains unknown. Therefore, this study was designed to evaluate the effect of diosmin in preventing kidney damage in response to Dox treatment. Male Wistar rats were randomly divided into four groups: control group, Dox group (20 mg/kg, i.p.), Dox plus low-dose diosmin group (100 mg/kg orally), and Dox plus high-dose diosmin group (200 mg/kg orally). A single intraperitoneal injection of Dox resulted in kidney damage as evidenced by significant alterations in kidney markers, histological abnormalities, and the attenuation of antioxidant defense mechanisms (GSH, SOD, and CAT). Moreover, Dox treatment significantly altered the expression of oxidative stress, inflammatory, and anti-apoptotic protein markers. Diosmin pretreatment alleviated Dox-induced nephrotoxicity by ameliorating the antioxidant mechanism, decreasing inflammation and apoptosis, and restoring kidney architecture. In conclusion, our results indicate that diosmin is a promising therapeutic agent for the prevention of nephrotoxicity associated with DOX.

Abstract
The aim of this study was to investigate the protective efficacy of diosmin against subacute deltamethrin exposure. For this purpose, 40 male Wistar albino rats were used. The animals were assigned to the following 4 groups: control group (received corn oil vehicle alone), diosmin-treated group (50 mg/kg bw/day orally), deltamethrin-exposed group (5 mg/kg bw/day, orally) and coadministered group (5 mg/kg bw/day deltamethrin and 50 mg/kg bw/day diosmin, orally) for 28 days. Some lipid peroxidation/antioxidant status/biochemical markers were evaluated in blood/tissue (liver, kidney, brain, heart and testis) samples and the histopathological architecture was assessed. Compared with the control group, no alteration was detected in the parameters and histological findings of the diosmin-treated group. Deltamethrin toxicity was associated with significantly increased plasma, cardiac, hepatic, renal, cerebral and testicular levels of MDA and NO, and significantly decreased GSH levels (p < 0.05). Antioxidant enzyme status (SOD, CAT and GSH-Px activities) displayed either decrease or increase (p < 0.05). Significant increase was detected in AST and ALT activities and urea and creatinine levels (p < 0.05). The values of the group coadministered with deltamethrin and diosmin were similar to the values of the control group. Diosmin ameliorated deltamethrin-induced lymphocytic and histiocytic infiltration and subendocardial oedema in the heart. Combined administration also minimized hepatic, renal, testicular and cerebral histopathological findings. The alterations detected in various toxicological parameters correlated well with the histopathological changes observed in various organs. In conclusion, it is suggested that diosmin could provide protection against deltamethrin-induced toxicity and organ damage in rats.

Abstract
Sterculia tragacantha (ST) Lindl leaf is commonly used locally in the management of diabetes mellitus (DM) and its complications. This study was aimed at assessing the valuable effects of ST leaf on streptozotocin-diabetic cardiomyopathy (DCM). Streptozotocin was administered intraperitoneally to the experimental animals to induce DM, and hence, placed on different doses of ST for 14 days. Thereafter, on the 15th day of the experiment, the animals were euthanized, and a number of cardiomyopathy indices were investigated. The diabetic rats exhibited a momentous increase in hyperlipidemia, lipid peroxidation as well as a significant (p < 0.05) decline in antioxidant enzyme activities. The serum creatine kinase MB (CK-MB), C-reactive protein (CRP), cardiac troponin I, tumour necrosis factor-alpha (TNF-α) and urotensin II expression revealed a significant (p < 0.05) upsurge in diabetic rats. Also, the expression of GLUT4 and fatty acid-binding protein 3 (FABP3) were significantly (p < 0.05) reduced in diabetic rats. However, at the conclusion of the experimental trial ST significantly (p < 0.05) attenuated hyperlipidemia, oxidative stress biomarkers by augmenting the antioxidant enzyme activities and decrease in lipid peroxidation, ameliorated CK-MB, CRP, cardiac troponin I, TNF-α, and urotensin-II levels, and improved GLUT4 and FABP3 expressions. Similarly, the administration of ST prevented histological alterations in the heart of diabetic animals. Therefore, the obtained results suggest that ST could mitigate DCM in streptozotocin-induced diabetic rats.

Abstract
In this study, we used UPLC–MS/MS to determine diosmetin-7-o-β-d-glucoside in rat plasma and investigated its pharmacokinetics in rats. Six rats were given diosmetin-7-o-β-d-glucoside (5 mg/kg) by intravenous (i.v.) administration. The blood (150 μL) was withdrawn from the caudal vein after administration. Diazepam was used as an internal standard (IS), and a one-step acetonitrile precipitation method was used to process the plasma samples. Chromatographic separation was achieved using a UPLC BEH C18 column using a mobile phase of acetonitrile–0.1% formic acid with gradient elution. Electrospray ionization (ESI) tandem mass spectrometry in multiple reaction monitoring (MRM) mode with positive ionization was applied, 463.1 → 301.0 for diosmetin-7-o-β-d-glucoside, m/z 285.1 → 193.0 for diazepam (IS). Intra-day and inter-day precision of diosmetin-7-o-β-d-glucoside in rat plasma were less than 14%. The method was successfully applied in the pharmacokinetics of diosmetin-7-o-β-d-glucoside in rats after intravenous administration. The t1/2 of diosmetin-7-o-β-d-glucoside is 1.4 ± 0.4 h, which indicates the quick elimination.

Abstract
Diosmin, a naturally occurring flavonoid commonly present in citrus fruit, is known to exhibit anti-inflammatory, antimutagenic, antioxidant, and free radical scavenging as well as blood lipid lowering activities among others. Diosmin has also been used for the treatment of various diseases including diabetes mellitus and Alzheimer's disease. Our study explores the role of Diosmin in pulmonary toxicity (lung injury) induced by environmental contaminant benzo(a)pyrene [B(a)P]. Swiss Albino Mice (SAM) were administered with either Diosmin 100 or 200 mg/kg body weight daily for 14 days and then challenged with a single dose of B(a)P. On the 15th day, animals were sacrificed; lung tissues and blood were collected for molecular analysis. B(a)P administration in mice induced the thickening of lung epithelium, damaged alveolar architecture, and promoted inflammatory cell infiltration in the lung tissues. Also, B[a]P significantly increased the expression of NF-kB, COX-2, IL-6, Bax, cleaved caspase 3, and cleaved PARP proteins and decreased antioxidant enzyme levels. Diosmin-100 and Diosmin-200 significantly attenuated the damage to lung epithelium, alveolar architecture, and reduced inflammatory cell infiltration in the lung tissues of mice. Diosmin significantly (P < .05) attenuated the levels of oxidative stress markers: lactate dehydrogenase and xanthine oxidase. A decrease in expression of NF-kB, COX-2, IL-6, Bax, cleaved caspase 3, and cleaved PARP proteins in mice was challenged with B[a]P. Diosmin thus could be a promising therapeutic adjuvant against B[a]P-induced oxidative stress and lung damage.

Abstract
BACKGROUND Designing drug candidates against the urease enzyme, which has been found responsible for many pathological disorders in human beings as well as in animals, was done by insilico means. METHODS Studies were carried out on a designed library of diosmin derivatives with the help of Schrodinger's maestro package of molecular docking software against a crystallographic complex of plant enzyme Jack bean urease (PDB ID: 3LA4). Best twelve derivatives of diosmin were selected for synthesis by considering their interaction energy along with docking score and were further investigated for antioxidant, urease inhibitory and Anti-H. pylori activity by in- vitro method along with ADMET analysis. RESULTS In-vitro results of series concluded compounds D2a, D2d and D7 (IC50 12.6 ± 0.002, 14.14 ± 0.001 and 15.64 ± 0.012 µM respectively in urease inhibition and 5.195 ± 0.036, 5.39 ± 0.020 and 5.64± 0.005 µM in antioxidant behavior against DPPH) were found to be significantly potent with excellent docking score -11.721, -10.795, -10.188 and binding energy -62.674, -63.352, -56.267 kJ/ mol as compared to standard drugs thiourea and acetohydroxamic acid (-3.459, -3.049 and -21.156 kJ/mol and - 17.454 kJ/mol) whereas compounds D2b, D5b, D5d and D6 were found moderate in urease inhibitory activity. CONCLUSION Selected candidates from the outcome of in-vitro urease inhibitory were further examined for anti- H. pylori activity by a well diffusion method against H. pylori bacterium (DSM 4867). Compound D2a showed good anti-H. Pylori activity with a zone of inhibition 10.00 ± 0.00 mm and MIC value 500µg/mL as compared to standard drug acetohydroxamic acid having a zone of inhibition 9.00 ± 0.50mm and MIC 1000µg/mL. In- silico studies played an important role in designing the potent ligands against urease protein as well as in explaining the binding pattern of designed and synthesized ligand within the active pocket of jack bean urease protein. ADMET studies were also carried out to check the drug similarity of designed compounds by the means of quikprop module of molecular docking software. Hence, the present investigation studies will provide a new vision for the discovery of potent agents against H. pylori and urease associated diseases.

Abstract
In this study, the effect of diosmin against the adverse effects of lead exposure in rats was investigated. Wistar Albino race 40 male rats weighing 150-200 g 2-3 months were used. A total of 4 groups were assigned, one of which was control and the other 3 were trial groups. The rats in the control group were treated with dimethyl sulfoxide, which was used only as a vehicle in diosmin administration. Groups 2, 3, and 4 from the experimental group were given diosmin at a dose of 50 mg/kg.bw, lead acetate at the dose of 1000 ppm, lead acetate at the dose of 1000 ppm, and diosmin at a dose of 50 mg/kg.bw for 6 weeks, respectively. Application of lead acetate with drinking water and also diosmin was performed by oral catheter. At the end of the experimental period, blood was taken to dry and with heparin by puncture to the heart under light ether anesthesia. Following the blood samples, some organs of the rats (the liver, kidney, brain, heart, and testis) were removed. Some biochemical parameters (glucose, triglyceride, cholesterol, BUN, creatinine, uric acid, LDH, AST, ALT, ALP, total protein, albumin) were measured in serum. Some oxidative stress parameters in tissue samples and blood (MDA, NO, SOD, CAT, GSH-Px, GSH) were evaluated. Body and organ (the liver, kidney, brain, heart, and testis) weights were also evaluated at the end of the study. No significant change was observed in the parameters examined in the diosmin alone-treated group by comparison to control group. On the other hand, significant changes were found in the values of lead acetate-treated group comparing control group. It was observed that the values approached the values of the control group in the combination of lead and diosmin. Exposure to lead acetate at a dose of 1000 ppm for 6 weeks causes organ damage; however the diosmin application at a dose of 50 mg/kg.bw had a positive effect on the regression of tissue damage.

Abstract
BACKGROUND Diabetic cardiomyopathy (DCM) is a nonischemic myocardial disorder characterized by metabolic disturbances and oxidative stress in diabetic patients. The present paper aims to determine the protective effect of the phlebotrophic drug, diosmin, on DCM in a model of high-fat diet-fed and streptozotocin-induced type 2 diabetes in the rat. MATERIALS AND METHODS The animals were divided into 4 groups (8 rats/group) as follows: vehicle-treated nondiabetic control group, vehicle-treated diabetic group, diosmin (50 mg/kg)-treated diabetic group and diosmin (100 mg/kg)-treated diabetic group. Treatment was given once daily orally by gavage for 6 weeks. Oxidant and antioxidant stress markers, inflammatory markers and proapoptotic and antiapoptotic gene expression using quantified real-time polymerase chain reaction were investigated. RESULTS Diosmin treatment in diabetic rats lowered elevated blood glucose levels, homeostatic model assessment for insulin resistance, cardiac creatine kinase and lactate dehydrogenase enzymes, cardiac malondialdehyde and nitric oxide. Moreover, diosmin increased plasma insulin and c-peptide levels, cardiac glutathione content, superoxide dismutase, catalase and glutathione S-transferase activities. Also, diosmin treatment significantly (P < 0.05) lowered the levels of interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α), down-regulated cardiac Bcl-2-associated X protein and caspase 3 and 9 and up-regulated B-cell lymphoma 2 mRNA expression levels. CONCLUSIONS Diosmin may have a sizeable therapeutic potential in the treatment of DCM due to antidiabetic, antioxidative stress, anti-inflammatory and antiapoptotic effects. Detailed studies are needed to disclose the precise mechanisms motivating the protective effect of diosmin.

Abstract
A total of 40, male Wistar Albino, 2-3-months-old rats were used and divided into four groups. Control group received the vehicle alone, diosmin group received 100 mg/kg.bw diosmin, the cadmium group received 200 ppm cadmium, cadmium plus diosmin group received 200 ppm cadmium, and 100 mg/kg.bw diosmin for 30 days. Some biochemical parameters (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and lactate dehydrogenase) and oxidative stress parameters (malondialdehyde [MDA], nitric oxide [NO], superoxide dismutase [SOD], catalase [CAT], gluthatione peroxidase [GSH-Px], and glutathione [GSH]) were analyzed in the samples. Histo-pathological findings were evaluated in the liver. The body weights and liver weights of the animals were measured. The MDA and NO levels and biochemical enzyme activities examined were increased, whereas SOD, CAT, and GSH-Px activities and GSH levels decreased in cadmium-exposed group. There were also negative changes in body weight, liver weight, and liver tissue histo-phathology. Positive improvements were observed in all these parameters evaluated of the group co-administered cadmium and diosmin. PRACTICAL APPLICATIONS: Cadmium is one of the common environmental pollutants. Diosmin is a type of flavonoid found mainly in citrus fruits. It can also be produced from hesperidine. This compound is used for medical purposes and also has strong antioxidant properties. One of the toxic effects mechanisms of cadmium is oxidative stress and causes liver damage with different pathways. This compound can be used as a supporting agent in addition to the main treatment options against liver damage in case of exposure to possible cadmium. This flavonoid can also be taken with food for prophylactic purposes.

Abstract
Oxidative stress plays an important role in the pathophysiology of many human disorders, while antioxidants prevent the development of various adverse symptoms. Diosmin is a natural flavonoid applied in vascular system disorders, especially in chronic venous insufficiency (CVI), and it plays a significant part in the alleviation of CVI symptoms. Due to antioxidant activity, it also has the ability to scavenge the oxygen free radicals and hence decreases the level of oxidative stress biomarkers, such as prostaglandins and their precursors—isoprostanes. In the study, the influence of diosmin treatment on the level of isoprostanes in plasma samples of patients suffering from CVI was examined. The qualitative analysis was performed using high-performance liquid chromatography with spectrometry detection (LC-MS). The statistically significant decrease of isoprostane content after 3 months of treatment was observed within the studied group; however, the most significant changes were observed in patients who smoke.

Abstract
Nephropathy is a serious complication of metabolic syndrome (MS), a global epidemic disorder. This study was undertaken to investigate the actions of diosmin and crocin, two natural ingredients, on diabetic nephropathy in a rat model of MS and the underlying mechanism(s). Metabolic syndrome was induced by the addition of 10% fructose to drinking water and placing the rats on high-salt diet for 16 weeks. Diosmin and Crocin were orally administrated daily for 10 weeks starting at week 6. At the end of study, arterial blood pressure was non-invasively recorded. Urine, serum and kidneys were collected for renal function, oxidative stress, glycemic parameters, inflammatory markers and histological analysis. Both Diosmin and Crocin improved insulin resistance, decreased blood pressure, uric acid, lipoproteins and blocked diabetic nephropathy as indicated by reduction of albumin excretion rate and albumin/creatinine ratio. They alleviated the impaired filtration in MS as indicated by increased creatinine clearance. They also ameliorated oxidative stress and the low-grade 1inflammation as indicated by reduction of serum TNF-α and inflammatory cells. These observations suggest that both Diosmin and Crocin alleviate metabolic syndrome and the associated nephropathy in rats, possibly, through inhibiting oxidative stress and inflammation.

Abstract
Although didymin, a flavonoid-O-glycosides compound naturally found in the citrus fruits, has been reported to be a potent anticancer agent in the prevention of various cancers, its role in the prevention of cardiovascular complications is unclear. Most importantly, its effect in the prevention of endothelial dysfunction, a pathological process involved in the atherogenesis, is unknown. We have examined the efficacy of didymin in preventing the high glucose (HG; 25 mM)-induced human umbilical vein endothelial cells (HUVECs) dysfunction. Our results indicate that incubation of HUVECs with HG resulted in the loss of cell viability, and pre-incubation of didymin prevented it. Further, didymin prevented the HG-induced generation of reactive oxygen species (ROS) as well as lipid peroxidation product, malondialdehyde. Pretreatment of HUVECs with didymin also prevented the HG-induced decrease in eNOS and increase in iNOS expressions. Further, didymin prevented the HG-induced monocytes cell adhesion to endothelial cells, expressions of ICAM-1 and VCAM-1 and activation of NF-κB. Didymin also prevented the release of various inflammatory cytokines and chemokines in HG-treated HUVECs. In conclusion, our results demonstrate that didymin with its anti-oxidative and anti-inflammatory actions prevents hyperglycemia-induced endothelial dysfunction and death. Thus, it could be developed as a potential natural therapeutic agent for the prevention of cardiovascular complications in diabetes.

Abstract
Protocatechuic acid (PCA) is a natural antioxidant with beneficial cardiovascular properties. In this study, the effect of supplementation with PCA was investigated in deoxycorticosterone acetate (DOCA)-salt hypertension. Male Wistar rats received DOCA (25 mg/kg, s.c.) twice weekly and 1% NaCl in drinking water and simultaneously treated with PCA (50, 100 and 200 mg/kg, p.o.) for 4 weeks. Systolic blood pressure (SBP) was detected using tail-cuff method. Electrolytes including Na+, K+ and chloride, catalase activity, glutathione, total antioxidant capacity, malondialdehyde (MDA) and hydroperoxides concentration were measured in serum samples. Body and organs weight, water intake and, kidney and heart histopathology were also evaluated. Administration of PCA reversed the changes caused by DOCA-salt approximately at all doses. At the lowest dose, PCA significantly decreased SBP (132.5 ± 4.0 vs 152.3 ± 4.5 mmHg, P < .05), serum sodium (138.5 ± 1.52 vs 141 ± 1.50, P < .05) and chloride level (101.6 ± 1.47 vs 110 ± 1.39, P < .01) and raised serum potassium level (3.8 ± 0.09 vs 3.1 ± 0.17, P < .05) compared with DOCA-salt hypertensive rats. PCA increased serum catalase activity, total antioxidant capacity and glutathione concentration and reduced MDA and hydroperoxides levels. PCA also improved organ weight changes, reduced water intake and moderately prevented histopathological changes of kidney and heart upon DOCA-salt administration. The present study indicates the antihypertensive and antioxidant effects of PCA against DOCA-salt hypertension.

Abstract
Cyclodextrins (CDs) have been widely used as a promising alternative in the formation of inclusion complexes with poorly soluble molecules. From this perspective, the present study aimed to study the inclusion complexes of diosmin in β-cyclodextrin, chemically quantify the diosmin-in-gel preparation and analyze the stability of the gels. Furthermore, we evaluated the effect of therapeutic pulsed ultrasound (TPU) in association with the gel-diosmin complex on the parameters of muscle damage and oxidative stress in rats. Serum creatine kinase (CK) levels were used as an indicator of skeletal muscle injury. Lipid peroxidation (thiobarbituric acid-reactive substances [TBARS]) and superoxide dismutase and catalase activities were used as indicators of oxidative stress. The results obtained indicated that the inclusion complex obtained by co-evaporation had the highest complexation efficiency and stability; there was no change in the features of diosmin on incorporation into the Carbopol gel. Additionally, a significant (p <0.05) decrease was observed in CK levels (TPU plus gel-diosmin: 178.4 ± 85.3 U/L) relative to the untreated group (527.8 ± 46.1 U/L). Levels of TBARS were lower in the TPU plus gel-diosmin group (0.008 ± 0.0004 nmol malondialdehyde/mg protein, p <0.05) compared with the untreated group (0.081 ± 0.011 nmol malondialdehyde/mg protein, p <0.05, n = 6). Catalase activity did not statistically significantly differ between the treatment groups, and superoxide dismutase activity was lower in the diosmin-treated group (0.320 ± 0.11 U/mg protein) compared with the untreated group (0.983 ± 0.40 U/mg protein). These results suggest that TPU in association with the diosmin-gel complex is effective in reducing muscle damage and oxidative stress after mechanical trauma.

Abstract
We investigate diosmin for its effect on the ARPE-19 human retinal pigment epithelial cells exposed to high glucose, a model of diabetic retinopathy (DR). After incubation for 4 days with a normal (5 mmol/L) concentration of D-glucose, ARPE-19 cells were exposed separately to normal or high concentrations of D-glucose (30 mmol/L) with or without diosmin at different concentrations (0.1, 1, 10 μg/mL) for another 48 h. Next, we assessed cell viability, reactive oxygen species (ROS) generation and antioxidant enzyme activities. In order to examine the underlying molecular mechanisms, we meanwhile analyzed the expressions of Bax, Bcl-2, total and phosphorylated JNK and p38 mitogen-activated protein kinase (MAPK). Diosmin dose dependently enhanced cell viability following high glucose treatment in ARPE-19 cells. The activities of superoxide dismutase and glutathione peroxidase, as well as the levels of reduced glutathione were decreased, while it was observed that levels of ROS in high glucose cultured ARPE-19 cells increased. High glucose also disturbed Bax and Bcl-2 expression, interrupted Bcl-2/Bax balance, and triggered subsequent cytochrome c release into the cytosol and activation of caspase-3. These detrimental effects were ameliorated dose dependently by diosmin. Furthermore, diosmin could abrogate high glucose-induced apoptosis as well as JNK and P38 MAPK phosphorylation in ARPE-19 cells. Our results suggest that treatment ARPE-19 cells with diosmin halts hyperglycemia-mediated oxidative damage and thus this compound may be a candidate for preventing the visual impairment caused by DR.

Simvastatin Ameliorates Diabetic Cardiomyopathy by Attenuating Oxidative Stress and Inflammation in Rats. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2017; 2017:1092015. [PMID: 29138670 PMCID: PMC5613468 DOI: 10.1155/2017/1092015] [Citation(s) in RCA: 78] [Impact Index Per Article: 11.1] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/19/2017] [Accepted: 08/06/2017] [Indexed: 12/15/2022]
Abstract
Simvastatin is a lipid-lowering agent used to treat hypercholesterolemia and to reduce the risk of heart disease. This study scrutinized the beneficial effects of simvastatin on experimental diabetic cardiomyopathy (DCM), pointing to the role of hyperglycemia-induced oxidative stress and inflammation. Diabetes was induced by intraperitoneal injection of streptozotocin and both control and diabetic rats received simvastatin for 90 days. Diabetic rats showed significant cardiac hypertrophy, body weight loss, hyperglycemia, and hyperlipidemia. Serum creatine kinase MB (CK-MB) and troponin I showed a significant increase in diabetic rats. Simvastatin significantly improved body weight, attenuated hyperglycemia and hyperlipidemia, and ameliorated CK-MB and troponin I. Simvastatin prevented histological alterations and deposition of collagen in the heart of diabetic animals. Lipid peroxidation and nitric oxide were increased in the heart of diabetic rats whereas antioxidant defenses were decreased. These alterations were significantly reversed by simvastatin. In addition, simvastatin decreased serum inflammatory mediators and expression of NF-κB in the diabetic heart. Cardiac caspase-3 was increased in the diabetic heart and decreased following treatment with simvastatin. In conclusion, our results suggest that simvastatin alleviates DCM by attenuating hyperglycemia/hyperlipidemia-induced oxidative stress, inflammation, and apoptosis.

Diosmin Attenuates Methotrexate-Induced Hepatic, Renal, and Cardiac Injury: A Biochemical and Histopathological Study in Mice. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2017; 2017:3281670. [PMID: 28819543 PMCID: PMC5551532 DOI: 10.1155/2017/3281670] [Citation(s) in RCA: 66] [Impact Index Per Article: 9.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/22/2017] [Revised: 06/08/2017] [Accepted: 06/12/2017] [Indexed: 12/20/2022]
Abstract
The current study was designed to investigate the beneficial role of diosmin, a biologically active flavonoid, against methotrexate- (MTX-) induced hepatic, renal, and cardiac injuries in mice. Male Swiss albino mice received a single intraperitoneal injection of MTX (at 20 mg/kg, body weight) either alone or in combination with oral diosmin (at 50 or 100 mg/kg body weight, for 10 days). Serum was used to evaluate tissue injury markers, while hepatic, renal, and cardiac tissue samples were obtained for determination of antioxidant activity as well as histopathological examination. Diosmin treatment ameliorated the MTX-induced elevation of serum alkaline phosphatase, aminotransferases, urea, creatinine, lactate dehydrogenase, and creatine kinases as well as plasma proinflammatory cytokines (interleukin-1-beta, interleukin-6, and tumor necrosis factor-alpha). Additionally, both diosmin doses significantly reduced tissue levels of malondialdehyde and nitric oxide and increased those of glutathione, glutathione peroxidase, glutathione reductase, glutathione S-transferase, superoxide dismutase, and catalase, compared to the MTX-intoxicated group. Histopathological examination showed that diosmin significantly minimized the MTX-induced histological alterations and nearly restored the normal architecture of hepatic, renal, and cardiac tissues. Based on these findings, diosmin may be a promising agent for protection against MTX-induced cytotoxicity in patients with cancer and autoimmune diseases.

Abstract
OBJECTIVE Traumatic brain injury (TBI) is one of the main causes of intellectual and cognitive disabilities in humans. Clinically, it is essential to limit the progress of cognitive impairment after TBI. It is reported that diosmin has a neuroprotective effect that can limit the progress of the impairment. The aim of this study was to evaluate the effects of diosmin on neurological score, memory, tumor necrosis factor-α (TNF-α) level and long-term potentiation in hippocampal dentate gyrus after the injury. METHODS A total of ninety six adult male Wistar rats were used as test subjects in this study. The animals were randomly assigned into one of the following three groups (n=32/group): Sham, TBI and diosmin (100mg/kg, p.o for seven consecutive days before TBI induction). TBI was induced into the animals by Marmarou's method. Briefly, a 200g weight was dropped from a 1m height through a free-falling tube onto the head of the anesthetized rats. RESULTS The veterinary coma scale scores, memory and long-term potentiation in TBI group showed significant decrease at different times after the onset of TBI when compared with Sham (p<0.001). The TNF-α level in the hippocampus of the TBI group of animals was significantly higher than that found in the test subjects from the Sham group (p<0.001). The pre-treatment of the TBI group with diosmin significantly improved their neurological scores, memory and long-term potentiation (p<0.001) when compared with the TBI group. The TNF-α level in hippocampus of the diosmin group was significantly lower than the TBI group (p<0.001). CONCLUSION Based on the results of the present study, pre-treatment with diosmin has protective effects against TBI-induced memory and long-term potentiation impairment. The effects of diosmin may be mediated through a decrement in the TNF-α concentration of hippocampus as a pro-inflammatory cytokine.

Abstract
Hyperglycaemia-mediated oxidative stress plays an imperative role in the progression of diabetic nephropathy. NF-kB is an important transcription factor in eukaryotes which regulates a diverse array of cellular process, including inflammation, immunological response, apoptosis, growth and development. Increased expression of NF-kB plays a vital role in the pathogenesis of many inflammatory diseases including diabetic nephropathy. Hence, the present study was designed to explore the nephroprotective nature of diosmin by assessing the various biochemical parameters, markers of oxidative stress and proinflammatory cytokine levels in alloxan-induced diabetic Wistar rats. Type 2 diabetes was induced in Wistar rats by single intraperitoneal injection of alloxan (120 mg/kg body weight). Seventy-two hours after the conformation of diabetes (blood glucose level ≥ 250 mg/dl), the rats were segregated into four groups, each group having six animals. Diabetic rats were treated with diosmin at a dose of 50 mg and 100 mg/kg body weight respectively. After the 28th day of treatment, rats were sacrificed, blood serum, plasma and kidney tissue were collected for various biochemical analysis. Inflammatory cytokine levels were measured through ELISA kit. Diosmin treatment produces significant reduction in the blood glucose and plasma insulin level and increases the body weight when compared with diabetic rats. Elevated level of malondialdehyde (MDA) and decrease levels of superoxide dismutase (SOD), catalase (CAT), reduced glutathione (GSH) and nitric oxide (NO) were significantly restored after 28 days of diosmin treatment. Diosmin treatment group also restores the normal architecture of the kidney tissue which was confirmed by histopathological examination. Moreover, oral administration of diosmin shows a significant normalization in the level of NF-kB, proving its pivotal role in maintaining renal function. The above ameliorative effects were more pronounced with diosmin at a dose of 100 mg/kg body weight. The above results permit us to conclude that treatment with diosmin halts hyperglycaemia-mediated oxidative stress and decline in pro-inflammatory cytokines and thus has beneficial anti-diabetic activity.

Abstract
In this study, Haliotis discus hannai (H. discus hannai) was fermented using Cordyceps militaris (C. militaris) and was investigated for the improvement of its antioxidant and anticancer potential after fermentation. Different radical scavenging activities of the extracts from fermented H. discus hannai with C. militaris mycelia (FHCM) were assessed by electron spin resonance. The antioxidant potential of FHCM was also determined on the basis of a ferric reducing antioxidant power assay and 2,2'-azinobis-(3-ethybenzothiazoline-6-sulfonic acid) radical scavenging activity. Higher antioxidant and radical scavenging activities were observed in FHCM than in the unfermented C. militaris mycelia or H. discus hannai alone. FHCM demonstrated an anticancer activity against melanoma B16F10 cell line. In addition, FHCM co-treatment with doxorubicin showed an increased anticancer effect in both in vitro and in vivo. Therefore, the present study suggests that the mycelial fermentation on H. discus hannai is highly suitable for pharmaceutical applications.

Abstract
Polyphenols are used as phlebotonic drugs, but their mechanism of action remains unknown. Since platelet activity and platelet-endothelial cell interactions are involved in the pathogenesis of cardiovascular disease, this work examines whether different flavonoid and coumarin drugs are able to inhibit platelet aggregation. This specific case of coumarins, the antiplatelet effect is not linked with a possible interaction over blood coagulation since this effect only dicoumarols have it. The antiplatelet capacity of polyphenols was assayed using peripheral blood platelets from healthy controls. The distribution of the different platelets subsets was quantified by flow cytometry, using the calcium ionophore as a pro-aggregant. The number of GPIIb/IIIa receptors occupied by the drugs was assayed by flow cytometry using two CD61 surface fluorescein antibodies. All the polyphenols tested inhibited platelet aggregation. A percentage antiplatelet activity of 88.91±7.98% was recorded for naringin, 48.43±8.84% for naringenin, 53.83±7.87% for esculetin, 54.65±6.91% for fraxetin, and 25.75±4.12% for coumarin. Naringin showed significantly greater percentage occupation of GPIIb/IIIa receptors than did naringenin (14.82±0.81% vs. 3.90±0.55%), and esculetin returned significantly higher values than fraxetin and coumarin (12.47±0.97 vs. 7.53±0.49 and 7.90±0.69 respectively). All drugs show important antiplatelet activity. Naringin was the best antiplatelet compound, showing the greatest antiplatelet activity and the highest percentage binding of GPIIb/IIIa receptors. However, any of the compounds used could be used in the prevention of cardiovascular disease.

Abstract
AIM The aim of the present study was to develop nanoproliposomes of lercanidipine, in order to overcome its poor biopharmaceutical properties and to improve its therapeutic efficacy in treating hypertension. MAIN METHODS The nanoproliposomes were prepared using a modified thin-film hydration method, and the formula was optimized by varying the ratio of lipids and the types of cryoprotectants. This optimized formulation was characterized in terms of its particle size, solid-state, drug release, in-situ absorption, in-vivo pharmacokinetics, and in-vivo anti-hypertensive activity in DOCA-salt induced hypertensive rats. Finally, a PK-PD correlation was established in order to understand the clinical implications of the developed novel nanoproliposomes. KEY FINDINGS The nanoproliposomes showed a particle size of 174.7nm and an entrapment efficiency of 85.4%. The in-vitro release displayed initial rapid release (19.33%) followed by a sustained release profile, releasing 88.37% of the encapsulated drug. The in-situ studies showed a significant increase in absorption rate across the rat intestinal membrane. The pharmacokinetics of this novel form indicated a 2.75-fold increase in the absolute bioavailability as compared to pure lercanidipine. In addition, the nanoproliposomes were found to be efficient in treating hypertension in DOCA-salt induced hypertensive rats. The PK-PD correlation demonstrated no time lag between effect and exposure, indicating that a direct PK-PD relationship can be expected in the clinic. SIGNIFICANCE These findings suggest that nanoproliposomes are promising carriers in improving the oral bioavailability and bioactivity of lercanidipine, and can be an effective therapy in the management of hypertension.

Abstract
In the literature, although there are many studies regarding complications of hypertension, information concerning its influence on visual evoked potentials (VEPs) is limited. This study aims to clarify the possible therapeutic effects of the preferential magnesium (Mg) treatment on VEPs in an experimental hypertension model. Rats were divided into four groups as follows: control, Mg treated (Mg), N(omega)-nitro-L-arginine methyl ester (L-NAME) hypertension, and L-NAME hypertension + Mg treated (L-NAME + Mg). Hypertension was induced by L-NAME which was given to rats orally over 6 weeks (25 mg/kg/day in drinking water). A magnesium-enriched diet (0.8 g/kg) was given to treatment groups for 6 weeks. Systolic blood pressure (SBP) was determined by using the tail-cuff method. Flash VEPs were recorded. Our results revealed that the SBP was significantly increased in the L-NAME group compared to control. Magnesium treatment significantly attenuated SBP in the hypertensive rats compared to the L-NAME group. The mean latencies of P1, N1, P2, N2, and P3 components were significantly prolonged in hypertensive rats compared to control. Treatment with Mg provided a significant decrease in the latencies of P1, N1, P2, N2, and P3 potentials in the L-NAME + Mg group compared to the L-NAME group. Plasma Mg levels were increased in the L-NAME + Mg group compared to the L-NAME group. No change was detected in the Mg levels of the brains in all experimental groups. Magnesium treatment had no effect on the brain nitrate/nitrite and thiobarbituric acid-reactive substances (TBARS) levels in hypertensive rats compared to non-treated rats. There was a positive correlation between the brain TBARS levels and SBP of the rats. The present study suggests that Mg supplementation has the potential to prevent VEP changes in the L-NAME-induced hypertension model.

Abstract
The natural antioxidant flavonoid diosmin, found in citric fruits, showed low antioxidant properties among other flavonoids due to its structural characteristics and low cytotoxicity against lung (A549) and breast (T47D, SKBR3 and MDAMB231) cancer cell lines. The anticancer behavior has been improved by the metal complex generated with the flavonoid and the oxidovanadium(IV) ion. This new complex, [VO(dios)(OH)3]Na5·6H2O (VOdios), has been synthesized and characterized both in solid and solution states. The interaction of the metal ion through the sugar moiety of diosmin precluded the improvement of the antioxidant effects. However, the cell-killing effects tested in human lung A549 and breast T47D, SKBR3 and MDAMB231 cancer cell lines, were enhanced by complexation. The anti-proliferative effects on the human lung cancer cell line were accompanied by cellular ROS generation and an increase in cytoplasm condensation. The breast cancer cell lines did not produce caspase3/7 activation, mitochondrial potential reduction and ROS generation. Therefore, a non-apoptotic form of cell death in a caspase- and oxidative stress-independent manner has been proposed. The protein binding ability has been monitored by the quenching of tryptophan emission in the presence of the compounds using bovine serum albumin (BSA) as a model protein. Both compounds could be distributed and transported in vivo and the complex displayed stronger binding affinity and higher contributions to the hydrogen bond and van der Waals forces.

Abstract
Sitagliptin, a dipeptidyl peptidase-4 inhibitor, has been reported to promote cardioprotection in diabetic hearts by limiting hyperglycemia and hyperlipidemia. However, little is known about the involvement of the Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway modulation in the cardioprotective effects of sitagliptin. The current study aimed to investigate the protective effects of sitagliptin against diabetic cardiomyopathy (DCM), focusing on the modulation of the JAK/STAT pathway. Diabetes was induced by streptozotocin injection, and rats received sitagliptin orally and daily for 90 days. Diabetic rats exhibited hyperglycemia, hyperlipidemia, and a significant increase in heart-to-body weight (HW/BW) ratio. Serum troponin I and creatine kinase MB, cardiac interleukin-6 (IL-6), lipid peroxidation, and nitric oxide levels showed significant increase in diabetic rats. In contrast, both enzymatic and nonenzymatic antioxidant defenses were significantly declined in the heart of diabetic rats. Histopathological study revealed degenerations, increased collagen deposition in the heart of diabetic rats. Sitagliptin alleviated hyperglycemia, hyperlipidemia, HW/BW ratio, histological architecture, oxidative stress, and inflammation, and rejuvenated the antioxidant defenses. In addition, cardiac levels of pJAK2 and pSTAT3 were increased in diabetic rats, an effect which was remarkably decreased after sitagliptin treatment. In conclusion, these results confer an evidence that sitagliptin has great therapeutic potential on DCM through down-regulation of the JAK/STAT signaling pathway.

High Performance Liquid Chromatography-mass Spectrometry Analysis of High Antioxidant Australian Fruits with Antiproliferative Activity Against Cancer Cells. Pharmacogn Mag 2016; 12:S181-94. [PMID: 27279705 PMCID: PMC4883077 DOI: 10.4103/0973-1296.182178] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2014] [Revised: 07/01/2015] [Indexed: 11/04/2022] Open
Abstract
BACKGROUND High antioxidant capacities have been linked to the treatment and prevention of several cancers. Recent reports have identified several native Australian fruits with high antioxidant capacities. Despite this, several of these species are yet to be tested for anticancer activity. MATERIALS AND METHODS Solvent extracts prepared from high antioxidant native Australian fruits were analyzed for antioxidant capacity by the di (phenyl)-(2,4,6-trinitrophenyl) iminoazanium free radical scavenging assay. Antiproliferative activities against CaCo2 and HeLa cancer cells were determined by a multicellular tumor spheroid-based cell proliferation assay. Toxicity was determined by Artemia franciscana bioassay. RESULTS Methanolic extracts of all plant species displayed high antioxidant contents (equivalent to approximately 7-16 mg of vitamin C per gram of fruit extracted). Most aqueous extracts also contained relatively high antioxidant capacities. In contrast, the ethyl acetate, chloroform, and hexane extracts of most species (except lemon aspen and bush tomato) had lower antioxidant contents (below 1.5 mg of vitamin C equivalents per gram of plant material extracted). The antioxidant contents correlated with the ability of the extracts to inhibit proliferation of CaCo2 and HeLa cancer cell lines. The high antioxidant methanolic extracts of all species were potent inhibitors of cell proliferation. The methanolic lemon aspen extract was particularly effective, with IC50 values of 480 and 769 μg/mL against HeLa and CaCo2 cells, respectively. In contrast, the lower antioxidant ethyl acetate and hexane extracts (except the lemon aspen ethyl acetate extract) generally did not inhibit cancer cell proliferation or inhibited to only a minor degree. Indeed, most of the ethyl acetate and hexane extracts induced potent cell proliferation. The native tamarind ethyl acetate extract displayed low-moderate toxicity in the A. franciscana bioassay (LC50 values below 1000 μg/mL). All other extracts were nontoxic. A total of 145 unique mass signals were detected in the lemon aspen methanolic and aqueous extracts by nonbiased high-performance liquid chromatography-mass spectrometry analysis. Of these, 20 compounds were identified as being of particular interest due to their reported antioxidant and/or anticancer activities. CONCLUSIONS The lack of toxicity and antiproliferative activity of the high antioxidant plant extracts against HeLa and CaCo2 cancer cell lines indicates their potential in the treatment and prevention of some cancers. SUMMARY Australian fruit extracts with high antioxidant contents were potent inhibitors of CaCo2 and HeLa carcinoma cell proliferationMethanolic lemon aspen extract was particularly potent, with IC50 values of 480 μg/mL (HeLa) and 769 μg/mL (CaCo2)High-performance liquid chromatography-mass spectrometry-quadrupole time-of-flight analysis highlighted and putatively identified 20 compounds in the antiproliferative lemon aspen extractsIn contrast, lower antioxidant content extracts stimulated carcinoma cell proliferationAll extracts with antiproliferative activity were nontoxic in the Artemia nauplii assay.

Therapeutic evaluation of rutin in two-kidney one-clip model of renovascular hypertension in rat. Life Sci 2016; 150:89-94. [PMID: 26920631 DOI: 10.1016/j.lfs.2016.02.080] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2015] [Revised: 02/19/2016] [Accepted: 02/22/2016] [Indexed: 12/31/2022]
Abstract
AIM The current investigation, designed to investigate the role of rutin in two-kidney one-clip (2K1C) induced renovascular dysfunction associated with hypertension in rat. MAIN METHODS The renovascular hypertension was developed by the application of vascular clip on left renal artery in rats; the right kidney was kept as such throughout the experimental protocol. The rutin (200 and 300 mg/kg; p.o.) and aliskiren (50mg/kg; p.o.) were administered for 9 consecutive days. The battery of pathophysiological tests i.e., systolic pressure, diastolic pressure and heart rate were performed to assess the anti-hypertensive effect of rutin. In addition, changes of kidney weight/body weight (KW/BW) ratio along with plasma renin content and renal tissue biomarkers i.e., thiobarbituric acid reactive substance (TBAR) and reduced glutathione (GSH) levels were estimated. KEY FINDINGS The administration of rutin significantly (P<0.05) attenuated the 2K1C of left kidney induced elevated systolic and diastolic pressure in a dose dependent manner. In addition, it also reduces the ratio of KW/BW along with a decrease in plasma renin content, tissue TBARS and increase the GSH levels. There were no significant changes observed in heart rate. Similar results were observed in aliskiren treated group. SIGNIFICANCE The anti-hypertensive effect of rutin may be a useful herbal medicine for the management of hypertension due to its potential free radical scavenging, inhibition of lipid peroxidation and plasma renin inhibitory action.

Abstract
Alcohol consumption has been commonly associated with gastric mucosal lesions including gastric ulcer. Diosmin (DIO) is a natural citrus flavone with remarkable antioxidant and anti-inflammatory features that underlay its protection against cardiac, hepatic and renal injuries. However, its impact on gastric ulcer has not yet been elucidated. Thus, the current study aimed to investigate the potential protective effects of DIO against ethanol-induced gastric injury in rats. Pretreatment with DIO (100 mg/kg p.o.) attenuated the severity of ethanol gastric mucosal damage as evidenced by lowering of ulcer index (UI) scores, area of gastric lesions, histopathologic aberrations and leukocyte invasion. These actions were analogous to those exerted by the reference antiulcer sucralfate. DIO suppressed gastric inflammation by curbing of myeloperoxidase (MPO) and tumor necrosis factor-α (TNF-α) levels along with nuclear factor kappa B (NF-κB) p65 expression. It also augmented the anti-inflammatory interleukin-10 (IL-10) levels. Meanwhile, DIO halted gastric oxidative stress via inhibition of lipid peroxides with concomitant enhancement of glutathione (GSH), glutathione peroxidase (GPx) and the total antioxidant capacity (TAC). With respect to gastric mucosal apoptosis, DIO suppressed caspase-3 activity and cytochrome C (Cyt C) with enhancement of the anti-apoptotic B cell lymphoma-2 (Bcl-2) in favor of cell survival. These favorable actions were associated with upregulation of the gastric cytoprotective prostaglandin E2 (PGE2) and nitric oxide (NO). Together, these findings accentuate the gastroprotective actions of DIO in ethanol gastric injury which were mediated via concerted multi-pronged actions, including suppression of gastric inflammation, oxidative stress and apoptosis besides boosting of the antioxidant and the cytoprotective defenses.
