Ojo AB, Adanlawo IG. Antioxidant, antidiabetic, and anti-inflammatory activities of flavonoid-rich fractions of Solanum anguivi Lam. fruit: In vitro and ex vivo studies. Heliyon 2024; 10:e31895. [PMID: 38841505 PMCID: PMC11152952 DOI: 10.1016/j.heliyon.2024.e31895] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2023] [Revised: 04/24/2024] [Accepted: 05/23/2024] [Indexed: 06/07/2024] Open
Abstract
Diabetes mellitus is a major, rapidly growing endocrine disorder in most countries. The high cost and side effects of conventional drugs for the management of this disease have shifted attention to medicinal plants. Solanum anguivi (S. anguivi) fruits has been reported to be a very good and rich source of polyphenols such as flavonoids, that can be exploited. Flavonoids are plant secondary metabolites widely found in vegetables, fruits and seeds and are known to be of medicinal significance in different range of diseases like diabetes. This study involved in vitro and ex vivo assays on the antioxidant, anti-inflammatory, and antidiabetic properties of flavonoid-rich fractions of S. anguivi fruits. Healthy male Wistar rats (n = 5) weighing 150-180 g were used for ex vivo antioxidant and antidiabetic studies, their liver was exercised for the experiment. The percentage yields of the three flavonoid-rich fractions (Fr. A, B, and C) of S. anguivi fruits obtained from the column chromatographic technique were 15.53 ± 0.75, 11.53 ± 0.80, and 10.17 ± 0.49 mg/g quercetin equivalents. The three fractions (A, B, and C) of S. anguivi fruits significantly scavenged both 2,2-diphenyl-1-picrylhydrazyl (DPPH) with fraction A having the lowest IC50 value (26.14 ± 1.06 μg/ml) compared with fraction B (37.78 ± 5.12 μg/ml) and fraction C (38.24 ± 2.40 μg/ml) when compared with ascorbic acid with the least IC50 value (15.27 ± 0.34 μg/ml). While fraction A (19.61 ± 1.19 μg/ml) scavenged nitric oxide (NO) radicals better than fraction B (22.97 ± 0.55 μg/ml) and fraction C (49.95 ± 6.18 μg/ml). Although ascorbic acid had better scavenging ability than the three fractions (17.23 ± 0.16 μg/ml). The flavonoid-rich fraction A shows better result in inhibiting α-glucosidase with IC50 value of 16.24 μg/ml compared to fraction B (128.04 μg/ml) and fraction C (143.16 μg/ml). For α-amylase, flavonoid-rich fraction A had an IC50 of 31.50 μg/ml compared to B (84.32 μg/ml) and C (145.40 μg/ml). The various controls also showed promising results with acarbose having IC50 of 3.93 μg/mL and 15.66 μg/mL respectively for α-glucosidase and α-amylase. Our findings also showed that FeSO4-induced tissue damage decreased the levels of GSH, SOD, and CAT activities while increasing the levels of MDA. In contrast, following treatment with the three flavonoid fractions of S. anguivi fruits helped to restore these parameters to near-normal levels, by significantly increasing the potential of GSH, SOD, CAT and reducing the levels of MDA which signifies that flavonoid-rich fractions of S. anguivi have great potential to address complications arising from oxidative stress. In addition, the three flavonoid-rich fractions A, B, and C of S. anguivi fruits exhibited ex vivo anti-inflammatory properties via reduced nitric oxide levels in iron-induced oxidative damage. Data obtained from this study shows that the flavonoid-rich fraction of S. anguivi possess anti-diabetic property via inhibition of α-glucosidase and α-amylase and antioxidant property via free radical scavenging. Also, comparing all the fractions, flavonoid-rich fraction A appears to be more potent compared to the fractions B and C. Further research will be needed in isolating and as well applying the fractions in real life situations in the management of diabetes.

Nephroprotective Effect of Hibiscus Sabdariffa Leaf Flavonoid Extracts via KIM-1 and TGF-1β Signaling Pathways in Streptozotocin-Induced Rats. ACS OMEGA 2024; 9:19334-19344. [PMID: 38708257 PMCID: PMC11064007 DOI: 10.1021/acsomega.4c00254] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/13/2024] [Revised: 04/05/2024] [Accepted: 04/08/2024] [Indexed: 05/07/2024]
Abstract
Diabetes-induced kidney damage represents a substantial health hazard, emphasizing the imperative to explore potential therapeutic interventions. This study investigates the nephroprotective activity of flavonoid-rich extracts from Hibiscus sabdariffa leaves in streptozotocin-induced diabetic rats. The flavonoid-rich extracts of H. sabdariffa leaves was obtained using a standard procedure. The animals were induced with streptozotocin and thereafter treated with both low (LDHSFL) and high doses (HDHSFL) of flavonoid-rich extracts from H. sabdariffa leaves and metformin (MET), and other groups are diabetic control (DC) and normal control (NC). The study assesses diverse renal parameters, encompassing kidney redox stress biomarkers, serum electrolyte levels, kidney inflammatory biomarkers, serum concentrations of creatinine, urea, and uric acid, kidney phosphatase activities, renal histopathology, and relative gene expressions of kidney injury molecule-1 (KIM-1) and transforming growth factor beta-1 (TGF-1β), comparing these measurements with normal and diabetic control groups (NC and DC). The findings indicate that the use of extracts from H. sabdariffa leaves markedly (p < 0.05) enhanced renal well-being by mitigating nephropathy, as demonstrated through the adjustment of various biochemical and gene expression biomarkers, indicating a pronounced antioxidative and anti-inflammatory effect, improved kidney morphology, and mitigation of renal dysfunction. These findings suggest that H. sabdariffa leaf flavonoid extracts exhibit nephroprotective properties, presenting a potential natural therapeutic approach for the treatment of diabetic nephropathy.

Skeels in glycation induced diabetic nephropathy via RAGE-NF-κB pathway and extracellular proteins modifications: A molecular approach. JOURNAL OF ETHNOPHARMACOLOGY 2024; 322:117573. [PMID: 38110133 DOI: 10.1016/j.jep.2023.117573] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 11/23/2023] [Accepted: 12/07/2023] [Indexed: 12/20/2023]
Abstract
ETHNOPHARMACOLOGY RELEVANCE Syzygium cumini (L.) Skeels (SC), an ancient medicinal plant, is used as a complementary and alternative medicine for treating diabetes mellitus and its associated complications, such as diabetic nephropathy (DN). Phytochemicals present in SC homeopathic formulations possess anti-glycemic, anti-glycation, anti-inflammatory, and antioxidant properties. Additionally, the non-enzymatic formation of advanced glycation end products (AGEs) increases during hyperglycemia in diabetes. AGEs interaction with their receptor of AGEs (RAGE) promotes inflammation via Nuclear Factor-κB (NF-κB) and the accumulation of Extracellular Matrix (ECM) proteins, contributing to the renal dysfunction in DN. However, the molecular mechanism through which SC formulations interact with the AGEs-RAGE-NF-κB pathway has not yet been investigated. AIM This study aims to examine the impact of SC formulations on the RAGE-NF-κB pathway and ECM protein modifications in glycation-induced DN using a molecular approach. MATERIALS AND METHODS Human serum albumin (10 mg/ml) was glycated with MGO (55 mM) in the presence of SC formulations - Mother tincture (MT), 30C, 200C for 7 days. Glycated samples were added to renal cells (HEK 293) for 24 h. Subsequently, cellular gene and protein expressions of RAGE, NF-κB, vascular endothelial growth factor (VEGF), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), collagen IV (Col IV), and fibronectin were determined using RT-qPCR and Western blot analysis. The immunofluorescence, luciferase assay, and chromatin immunoprecipitation techniques were employed to gain insights into glycation-induced NF-κB nuclear translocation, transcriptional activity, and its effect on RAGE promoter activity in SC-treated cells. RESULTS SC formulations significantly downregulated glycation-induced elevated levels of RAGE and NF-κB. Mechanistically, SC formulations prevented NF-κB nuclear translocation, transcriptional activity, and RAGE promoter activity. Also, SC formulations significantly attenuated glycation-enhanced expressions of inflammatory cytokines (IL-6, TNF-α, and VEGF) and ECM proteins (Col IV and fibronectin). CONCLUSION Our findings enlighten the molecular mechanism of SC in DN by targeting the AGEs-RAGE-NF-κB signaling pathway, inflammatory responses, and ECM accumulation. Hence, the study validates the protective role of SC formulations and signifies its novel potential for treating DN.

Identification of a 10-mer peptide from the death domain of MyD88 which attenuates inflammation and insulin resistance and improves glucose metabolism. Biochem J 2024; 481:191-218. [PMID: 38224573 DOI: 10.1042/bcj20230369] [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: 08/26/2023] [Revised: 01/12/2024] [Accepted: 01/15/2024] [Indexed: 01/17/2024]
Abstract
Insulin resistance (IR) is the key pathophysiological cause of type 2 diabetes, and inflammation has been implicated in it. The death domain (DD) of the adaptor protein, MyD88 plays a crucial role in the transduction of TLR4-associated inflammatory signal. Herein, we have identified a 10-residue peptide (M10), from the DD of MyD88 which seems to be involved in Myddosome formation. We hypothesized that M10 could inhibit MyD88-dependent TLR4-signaling and might have effects on inflammation-associated IR. Intriguingly, 10-mer M10 showed oligomeric nature and reversible self-assembly property indicating the peptide's ability to recognize its own amino acid sequence. M10 inhibited LPS-induced nuclear translocation of NF-κB in L6 myotubes and also reduced LPS-induced IL-6 and TNF-α production in peritoneal macrophages of BALB/c mice. Remarkably, M10 inhibited IL-6 and TNF-α secretion in diabetic, db/db mice. Notably, M10 abrogated IR in insulin-resistant L6 myotubes, which was associated with an increase in glucose uptake and a decrease in Ser307-phosphorylation of IRS1, TNF-α-induced JNK activation and nuclear translocation of NF-κB in these cells. Alternate day dosing with M10 (10 and 20 mg/kg) for 30 days in db/db mice significantly lowered blood glucose and improved glucose intolerance after loading, 3.0 g/kg glucose orally. Furthermore, M10 increased insulin and adiponectin secretion in db/db mice. M10-induced glucose uptake in L6 myotubes involved the activation of PI3K/AKT/GLUT4 pathways. A scrambled M10-analog was mostly inactive. Overall, the results show the identification of a 10-mer peptide from the DD of MyD88 with anti-inflammatory and anti-diabetic properties, suggesting that targeting of TLR4-inflammatory pathway, could lead to the discovery of molecules against IR and diabetes.

Abstract
BACKGROUND This study assessed the hepatoprotective potential of flavonoid-rich extracts from Gongronema latifolium Benth on diabetes-induced type 2 rats via Fetuin-A and tumor necrosis factor-alpha (TnF-α). METHODS In a standard procedure, the flavonoid-rich extract was prepared. For experimental rats, streptozotocin was injected intraperitoneally (45 mg/kg body weight) to induce diabetes mellitus. Following this, rats were given 5% of glucose water for 24 h. Hence, the animals were randomly divided into five groups of ten rats each, consisting of non-diabetic rats, diabetic controls, diabetic rats treated with low and high doses of flavonoid rich-extracts from Gongronema latifolium leaf (FREGL) (13 and 26 mg/kg, respectively), and diabetic rats treated with 200 mg/kg of metformin glibenclamide orally for 3 weeks. Afterwards, the animals were sacrificed, blood and liver were harvested to evaluate different biochemical parameters, hepatic gene expressions and histological examinations. RESULTS The results revealed that FREGL (especially at the low dose) significantly (p < 0.05) reduced alanine transaminase (ALT), aspartate aminotransferase (AST) and alkaline phosphate (ALP) activities, lipid peroxidation level, as well as relative gene expressions of fetuin-A and TNF-α in diabetic rats. Furthermore, diabetic rats given various doses of FREGL showed an increase in antioxidant enzymes and hexokinase activity, as well as glucose transporters (GLUT 2 and GLUT 4), and glycogen levels. In addition, histoarchitecture of the liver of diabetic rats administered FREGL (especially at the low dose) was also ameliorated. CONCLUSION Hence, FREGL (particularly at a low dose) may play a substantial role in mitigating the hepatopathy complication associated with diabetes mellitus.

Abstract
Ethnopharmacological Relevance: The management of diabetes over the years has involved the use of herbal plants, which are now attracting interest. We assessed the antidiabetic properties of aqueous extract of C. purpureus shoots (AECPS) and the mechanism of action on pancreatic ß-cell dysfunction. Methods: This study was conducted using Thirty-six 36) male Wistar rats. The animals were divided into six equal groups (n = 6) and treatment was performed over 14 days. To induce diabetes in the rats, a single dose of 65 mg/kg body weight of alloxan was administered intraperitoneal along with 5% glucose. HPLC analysis was carried out to identified potential compounds in the extract. In vitro tests α-amylase, and α-glucosidase were analyzed. Body weight and fasting blood glucose (FBG) were measured. Biochemical parameters, such as serum insulin, liver glycogen, hexokinase, glucose-6-phosphate (G6P), fructose-1,6-bisphosphatase (F-1,6-BP), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and nuclear factor kappa B (NF-ĸB), were analyzed. Additionally, mRNA expressions of phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT), B-cell lymphoma 2 (Bcl-2), and proliferating cell nuclear antigen (PCNA) were each evaluated. Results: This in vitro study showed inhibitory potency of Cenchrus purpureus extract (AECPS) as compared with the positive controls. AECPS showed a gradual decrease in alloxan-induced increases in FBG, total cholesterol (TC), triglycerides (TG), low density lipoprotein (LDL-c), G6P, F-1,6-BP, malondialdehyde (MDA), IL-6, TNF-α, and NF-ĸB and increased alloxan-induced decreases in liver glycogen, hexokinase, and high density lipoprotein (HDL-c). The diabetic control group exhibited pancreatic dysfunction as evidenced by the reduction in serum insulin, homeostasis model assessment of ß-cell function (HOMA-β), expressions of PI3K/AKT, Bcl-2, and PCNA combined with an elevation in homeostatic model assessment of insulin resistance (HOMA-IR). High performance liquid chromatography (HPLC) revealed 3-O-rutinoside, ellagic acid, catechin, rutin, and kaempferol in AECPS. Conclusion: AECPS showed efficient ameliorative actions against alloxan-induced pancreatic dysfunction, oxidative stress suppression as well as, inflammation, and apoptosis via the activation of PI3K/AKT signaling pathways.

Abstract
Syzygium cumini, locally known as Jamun in Asia, is a fruit-bearing crop belonging to the Myrtaceae family. This study aims to summarize the most recent literature related to botany, traditional applications, phytochemical ingredients, pharmacological activities, nutrition, and potential food applications of S. cumini. Traditionally, S. cumini has been utilized to combat diabetes and dysentery, and it is given to females with a history of abortions. Anatomical parts of S. cumini exhibit therapeutic potentials including antioxidant, anti-inflammatory, analgesic, antipyretic, antimalarial, anticancer, and antidiabetic activities attributed to the presence of various primary and secondary metabolites such as carbohydrates, proteins, amino acids, alkaloids, flavonoids (i.e., quercetin, myricetin, kaempferol), phenolic acids (gallic acid, caffeic acid, ellagic acid) and anthocyanins (delphinidin-3,5-O-diglucoside, petunidin-3,5-O-diglucoside, malvidin-3,5-O-diglucoside). Different fruit parts of S. cumini have been employed to enhance the nutritional and overall quality of jams, jellies, wines, and fermented products. Today, S. cumini is also used in edible films. So, we believe that S. cumini’s anatomical parts, extracts, and isolated compounds can be used in the food industry with applications in food packaging and as food additives. Future research should focus on the isolation and purification of compounds from S. cumini to treat various disorders. More importantly, clinical trials are required to develop low-cost medications with a low therapeutic index.

Abstract
INTRODUCTION The present study access the effect of the flavonoid-rich isolate from Gongronema latifolium against cardiomyopathy in a streptozotocin-rich extract. MATERIAL AND METHODS The flavonoid-rich isolate from G. latifolium leaf (FREGL) was prepared using a standard method. A single injection of streptozotocin was induced into the experimental rats. The experimental animals were divided into five groups as non-diabetic rats, diabetic control, diabetic rats administered low and high doses of FREGL (13 and 26 mg/kg), and metformin glibenclamide orally for 21 days. Hence, the experimental animals were sacrificed; blood and heart were harvested to determine diverse biochemical parameters, including the gene expressions of serpin A3 and socs3-a as well as histological examination. RESULTS The results demonstrated that FREGL significantly (p < 0.05) reduced fasting blood glucose, total cholesterol, low density lipoprotein (LDL), triglyceride (TG), lipid peroxidation levels, as well as the activities of lactate dehydrogenase and creatine kinase-MB, including the relative gene expressions of serpin A3 and Socs3-A in diabetic rats. Also, diabetic rats that received different doses of FREGL showed a substantial rise in insulin and high density lipoprotein (HDL) levels, and antioxidant enzyme activities, as well as, normal histoarchitecture of the heart tissues. CONCLUSION Therefore, FREGL may be beneficial in alleviating diabetic cardiomyopathy.

Abstract
OBJECTIVES To assess the ameliorative activity of polyphenolic-rich extracts of Basella rubra leaves on β-cell dysfunction in type-II diabetes (T2DM). METHODS Total phenolic and flavonoid contents; α-amylase and α-glucosidase inhibitory actions and qualitative analysis of the bioactive compounds of the polyphenolic-rich extract of B. rubra leaves were investigated using gas chromatography-mass spectroscopy (GC-MS). Diabetes mellitus (DM) was induced by single intraperitoneal injection of streptozotocin (60 mg/kg body weight) and the rats were orally given bound phenolic (BPE) and free phenolic extracts (FPE) of B. rubra (B.R) leaves at 200 and 400 mg/kg b.w once daily for 14 days. Biochemical analyses were executed for evaluation of serum insulin, serum lipid profile concentrations, liver enzymes activities. RESULTS The extracts demonstrated antioxidant potentials and enzymes inhibitory activities in dose dependent manner; and several bioactive compounds as revealed by GC-MS. BPE and FPE considerably (p<0.05) reduced hyperglycemia, improved serum insulin levels, ameliorated the concentration of serum lipid profiles and improved liver antioxidant activities. Additionally, BPE and FPE expressively decreased alanine aminotransferases (ALT), aspartate aminotransferases (AST), gamma-glutamyl transferase (GGT) activities along with levels of bilirubin and urea when compare to diabetic control rats. CONCLUSIONS Data acquired exhibited the ability of BPE and FPE to improve pancreatic beta-cell in streptozotocin-induced rats.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 269:113715. [PMID: 33358853 DOI: 10.1016/j.jep.2020.113715] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Revised: 12/01/2020] [Accepted: 12/18/2020] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The increasing national prevalence of diabetes mellitus (DM) and its complications have overstretched the health care system in Tanzania and influenced patients to use herbal medicines as alternative therapeutic strategies. Therefore, an urgent need exists to validate the safety and efficacy of plants used locally. AIM OF THE STUDY To identify plants used for the management of DM in Tanzania and analyses their pharmacological, phytochemistry, and safety evidence with a special focus on the mechanism of action. METHODS Researchers searched Medline, web of science, and Scopus for published articles. Also, specialized herbarium documents of Muhimbili Institute of traditional medicine were reviewed. Articles were assessed for relevance, quality, and taxonomical accuracy before being critically reviewed. RESULTS We identified 62 plant species used locally for DM management. Moringa oleifera Lam. and Cymbopogon citratus (D.C) stapf were the most mentioned. Fifty-four phytochemicals from 13 species had DM activities. These were mainly; polyphenolics, phytosterols, and triterpenoids. Extracts, fractions, and pure compounds from 18 species had in vitro antidiabetic activities of which 14 had α-glucosidase and α-amylase inhibition effects. The most studied -Momordica charantia L. increased; glucose uptake and adiponectin release in 3T3-L1 adipocytes, insulin secretion, insulin receptor substrate-1 (IRS-1), GLUT-4 translocation, and GLP-1 secretion; and inhibited protein tyrosine phosphatase 1 B (PTP1B). Preclinical studies reported 30 species that lower plasma glucose with molecular targets in the liver, skeletal muscles, adipose tissues, pancreases, and stomach. While three species; Aspilia mossambiscensis (Oliv.) Willd, Caesalpinia bonduc (L.) Roxb, and Phyllanthus amarus Schumach. & Thonn. had mild toxicity in animals, 33 had no report of their efficacy in DM management or toxicity. CONCLUSION Local communities in Tanzania use herbal medicine for the management of DM. However, only a fraction of such species has scientific evidence. A. mossambiscensis, C. bonduc., and P. amarus had mild toxicity in animals. Together, our findings call for future researches to focus on in vitro, in vivo, and phytochemical investigation of plant species for which their use in DM among the local communities in Tanzania have not been validated.

Abstract
Obesity is a disease growing at an alarming rate and numerous preclinical studies have proven the role of polyphenols in managing this disease. This systematic review explores the prebiotic effect of polyphenols in the management of obesity among animals fed on a high-fat diet. A literature search was carried out in PubMed, Scopus, CINAHL, Web of Science, and Embase databases following the PRISMA guidelines. Forty-four studies reported a significant reduction in obesity-related parameters. Most notably, 83% of the studies showed a decrease in either body weight/visceral adiposity/plasma triacylglyceride. Furthermore, 42 studies reported a significant improvement in gut microbiota (GM), significantly affecting the genera Akkermansia, Bacteroides, Blautia, Roseburia, Bifidobacteria, Lactobacillus, Alistipes, and Desulfovibrio. Polyphenols’ anti-obesity, anti-hyperglycaemic, and anti-inflammatory properties were associated with their ability to modulate GM. This review supports the notion of polyphenols as effective prebiotics in ameliorating HFD-induced metabolic derangements in animal models.

Abstract
Diabetic Mellitus (DM) is a metabolic disorder that is concerning for people all over the world. DM is caused due to lack of insulin or ineffective production of insulin in the pancreas. A total of 463 million people were reported to have diabetes mellitus in 2019 and this number is predicted to rise up to 578 million by the year 2030 and 700 million by 2045. High blood sugar gives rise to many complications like diabetic retinopathy, diabetic nephropathy, atherosclerosis, hypercoagulability, cardiovascular disease, coronary heart disease, abdominal obesity, hypertension, hyperlipidemia, cerebrovascular disease, coronary artery disease, foot damage, skin complications, Alzheimer's disease, hearing impairment, and depression. These life-threatening complications make diabetes more severe than other diseases. Many synthetic drugs have been developed, but still, a complete cure is not provided by any of the molecules. Continuous use of some synthetic agents causes severe side effects, and thus the demand for non-toxic, affordable drugs still persists. Traditional treatments have been an extremely valued source of medicine all over human history. These are extensively used throughout the world, indicating that herbs are a growing part of modern and high-tech medicines. The World Health Organization (WHO) has listed a total of 21,000 plants, which are used for medicinal purposes around the world. Among them, more than 400 plants are available for the treatment of diabetes. Despite the fact that there are many herbal drugs available for treating diabetes, only a small number of these plants have undergone scientific and medical evaluation to assess their efficacy. Trigonella foenum-graecum, Allium sativum, Caesalpinia bonduc, Ferula assafoetida,etc., are some of the medicinal plants used for antidiabetic therapy. The presence of phenolic compounds, flavonoids, terpenoids, and coumarins is responsible for the antidiabetic nature of the medicinal plants. These constituents have shown a reduction in blood glucose levels. Pycnogenol, acarbose, miglitol, and voglibose are some of the examples of marketed drugs, which are obtained from natural origin and used as antidiabetic drugs. The active principles derived from the plants work through many antidiabetic mechanisms, which include inhibition of α-glucosidase, α-amylase, and protein tyrosine phosphatase 1B activities. One of the major advantages of herbal drugs is the low level of side effects attributed to these medicines, and this attracted various researchers to develop new molecules for the treatment of diabetes. In this review, recent advances in the field of herbal drugs to treat diabetes, prevent secondary complications from arising due to diabetes, and various herbal molecules in different stages of clinical trials will be emphasized upon.

Abstract
Camellia oleifera (C. oleifera) oil is known as "oriental olive oil". We previously reported the anti-inflammatory activity of C. oleifera oil was mainly attributed to the phenolic compounds, but the specific compounds remain uncovered. In this study, phenolic compounds in the form of free (11.92 μg GAE/g), esterified (37.57 μg GAE/g), glycosylated (128.71 μg GAE/g), and insoluble (47.53 μg GAE/g) were prepared from C. oleifera oil. Their anti-inflammatory activities were evaluated by lipopolysaccharide induced RAW 264.7 macrophage. Glycosylated fraction showed the highest anti-inflammatory activity as indicated by the low production of nitric oxide (NO), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6). Subsequently, 13 different glycosylated polyphenols were identified by UPLC-Q-TOF/MS, and the major compounds were purified for anti-inflammatory re-evaluation. Lower anti-inflammatory activities of compound 3 and compound 6 were observed when compared to kaempferol. Overall, these results would promote the utilization of phenolic compounds in C. oleifera oil.

Abstract
BACKGROUND Gongronema latifolium (G. latifolium) Benth. leaves are traditionally used to treat diabetes mellitus (DM) and other diseases in Nigeria and West Africa. This study was performed to evaluate the neuroprotective effect of aqueous extract of G. latifolium leaf against DM. Antidiabetic activity of G. latifolium extracts (6.36, 12.72 and 25.44 mg kg-1 , i.p.) was determined in alloxan-induced diabetic rats. Fasting blood glucose level and oxidative stress markers catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), malondialdehyde (MDA), and nitric oxide (NO) levels were measured. Cognitive biomarkers acetylcholinesterase (AChE), butyrylcholinesterase (BChE), dopamine (DOPA), serotonin, epinephrine and norepinephrine and cyclooxygenase (COX-2) were measured in the brain of controls and of G. latifolium-treated diabetic rats. RESULTS Administration of G. latifolium leaf extract to diabetic rats significantly restored the alterations in the levels of fasting blood glucose (FBG). The MDA and NO levels were significantly reduced with an improvement in CAT, SOD, and GPx activity in the kidneys and brains of diabetic rats treated with G. latifolium. Gongronema latifolium also significantly decreased the levels of AChE, BChE, DOPA, serotonin, epinephrine, and nor-epinephrine in diabetic rats. G. latifolium effectively ameliorated COX-2 in diabetic rats. CONCLUSION This study showed that leaf extract of G. latifolium improved antioxidant defense against oxidative stress. It displays a neuroprotective effect resulting in the modulation of brain neurotransmitters, which could be considered as a promising treatment therapy. © 2020 Society of Chemical Industry.

Antidiabetic activity of watermelon ( Citrullus lanatus) juice in alloxan-induced diabetic rats. J Diabetes Metab Disord 2020; 19:343-352. [PMID: 32550185 DOI: 10.1007/s40200-020-00515-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Accepted: 03/10/2020] [Indexed: 10/24/2022]
Abstract
Introduction Watermelon is one of the commonly eaten fruit in most homes in Nigeria and has been used in the management of diabetes mellitus traditionally. This study was carried out to explore the antidiabetic potential of watermelon (Citrullus lanatus) juice in alloxan-induced diabetic rats. Methods Watermelon juice was used for the determination of in vitro parameters such as 1,1-diphenyl-2-picryl-hydrazil (DPPH), nitric oxide and ferric reducing antioxidant potential (FRAP) as well as phytochemicals such as total phenol, total flavonoids. In vitro, α-glucosidase and α-amylase inhibitory activities were also accessed using standard procedures. Diabetes was induced in the rats by a single intraperitoneal (I.P) injection of freshly prepared alloxan (150 mg/kg body weight). The animals were randomly grouped into five groups of normal control, untreated diabetic control, diabetic rats administered 200 mg/kg body weight of metformin, diabetic rats administered 500 mg/kg body weight of watermelon (Citrullus lanatus) juice and diabetic rats administered 1000 mg/kg body weight of watermelon juice. The rats were sacrificed on the 14th day of the experiment and various in vivo biochemical parameters were also evaluated in the serum and tissue homogenates of diabetic rats. Results The watermelon juice exhibits anti-oxidant properties and inhibitory activities against α-glucosidase and α-amylase in a dose-dependent manner. Added to this, the administration of different doses of the watermelon juice significantly (p < 0.05) reduced the fasting blood glucose level, serum lipid profile, glucose-6-phosphatase, lipid peroxidation and anti-inflammatory activities in alloxan-induced diabetic rats. There was a significant (p < 0.05) increase in antioxidant enzyme activities, hexokinase activity as well as glucose transporters (GLUT 2 and GLUT 4) levels in diabetic rats administered different doses of Citrullus lanatus. Conclusion Taken together, this study demonstrates that watermelon (Citrullus lanatus) juice exhibits its antidiabetic potential in experimental diabetic animal model via multiple pathways involving modulation of glucose transporters, anti-inflammatory activities as well as antioxidant defense system and inhibition of α-glucosidase and α-amylase. This suggests that the watermelon (Citrullus lanatus) juice may have a useful clinical application in the management of diabetes mellitus and its metabolic complications if developed as adjuvant therapy.

Abstract
This study was focused on the phytochemical composition and biological activities of Anchusa officinalis and Melilotus officinalis polyphenolic-rich extracts obtained by nanofiltration. The high-performance liquid chromatography-mass spectrometry analysis showed that chlorogenic acid and rosmarinic acid were the main phenolic acids in both extracts. The main flavonoid compound from A. officinalis extracts is luteolin, whereas rutin and isoquercitrin are the main flavonoids in M. officinalis. M. officinalis polyphenolic-rich extract had the highest α-amylase (from hog pancreas) inhibitory activity (IC50 = 1.30 ± 0.06 μg/mL) and α-glucosidase (from Saccharomyces cerevisiae) inhibitory activity (IC50 = 92.18 ± 1.92 μg/mL). However, both extracts presented a significant α-glucosidase inhibitory activity. Furthermore, the hyaluronidase inhibition of polyphenolic-rich extracts also proved to be stronger (IC50 = 11.8 ± 0.1 μg/mL for M. officinalis and 36.5 ± 0.2 μg/mL for A. officinalis), but there was moderate or low lipoxygenase inhibition. The studies on the fibroblast cell line demonstrated that both A. officinalis and M. officinalis polyphenolic-rich extracts possess the cytotoxic effect at a concentration higher than 500 μg/mL. The experimental data suggest that both extracts are promising candidates for the development of natural antidiabetic and anti-inflammatory food supplements.

Abstract
Metabolic syndrome includes a series of metabolic abnormalities that leads to diabetes mellitus and cardiovascular diseases. Plant extracts, due to their unique advantages like anti-inflammatory, antioxidant, and insulin sensitizing properties, are interesting therapeutic options to manage MetS; however, the poor solubility and low bioavailability of lipophilic bioactive components in the herbal extracts are two critical challenges. Nano-scale delivery systems are suitable to improve delivery of herbal extracts. This review, for the first time, focuses on nanoformulations of herbal extracts in MetS and related complications. Included studies showed that several forms of nano drug delivery systems such as nanoemulsions, solid lipid nanoparticles, nanobiocomposites, and green-synthesized silver, gold, and zinc oxide nanoparticles have been developed using herbal extracts. It was shown that the method of preparation and related parameters such as temperature and type of polymer are important factors affecting physicochemical stability and therapeutic activity of the final product. Many of these formulations could successfully decrease the lipid profile, inflammation, oxidative damage, and insulin resistance in in vitro and in vivo models of MetS-related complications. Further studies are still needed to confirm the safety and efficacy of these novel herbal formulations for clinical application.

Abstract
Background Gongronema latifolium leaf is used traditionally to treat diabetes and other diseases. The present study aimed to provide the modulatory effect of G. latifolium on hyperglycemia, inhibitory effect of redox imbalance and inflammation in alloxan-induced nephropathy in Wistar rats. Methods Alloxan monohydrate was used to induce diabetes by an intraperitoneal injection of (150 mg/kg). Three diabetic groups were administered aqueous leaf extract of G. latifolium at 6.36, 12.72 and 25.44 mg/kg bodyweight (BW) respectively; a group was administered with metformin (5 mg/kg BW), while the other two were served as positive and negative control. Thereafter, fasting blood glucose, antioxidant enzymes, malondialdehyde (MDA) level, interleukin 2 and 6 were determined. Results G. latifolium leaf significantly (p < 0.05) reduced the alloxan-induced increases in blood glucose, MDA, interleukin 2 and interleukin 6 level and increased the alloxan-induced decreases in superoxide dismutase, catalase, glutathione peroxidase, glutathione reduced and glutathione transferase activity. All these changes compared with those of metformin-treated diabetic rats. Conclusion The data from this study suggest that G. latifolium modulates glucose homeostasis as well as inhibiting redox imbalance and inflammation in diabetic rats, which may be attributed to the effects of its phytochemical constituents such as saponins, flavonoids and alkaloids. It also indicated that inhibition of inflammatory cytokines and redox imbalance are likely mechanisms by which G. latifolium leaf exert its antidiabetic action.

Abstract
Phenolic compounds are important functional bioactive substances distributed in various food plants. They have gained wide interest from researchers due to their multiple health benefits. There are two forms of phenolic compounds: free form and bound form. The latter is also called bound phenolics (BPs), which are found mainly in the cell wall and distributed in various tissues/organs of the plant body. They can either chemically bind to macromolecules and food matrixes or be physically entrapped in food matrixes and intact cells. Various isolation methods, including chemical, biological, and physical methods, have been employed to extract BPs from plants. BPs have been shown to have strong biological activities, including antioxidant, probiotic, anticancer, anti-inflammation, antiobesity, and antidiabetic effects as well as beneficial effects on central nervous system diseases. This review summarizes research findings on these topics to help in better understanding of BPs and provide comprehensive information on their health effects.

Abstract
Context: Gongronema latifolium Benth (Asclepiadaceae) has been highly utilized in controlling diabetes mellitus traditionally in the eastern part of Nigeria. Objectives: Antihyperglycaemic and related gene expressions of aqueous extract of Gongronema latifolium leaf in alloxan-induced diabetic rats. Materials and methods: Forty-eight female Wistar rats were induced intraperitoneally using alloxan (150 mg/kg body weight). The rats were separated into six groups (n = 8) as follows: non-diabetic control, diabetic control, diabetic rats administered 5 mg/kg body weight of metformin, and diabetic rats administered 6.36, 12.72 and 25.44 mg/kg body weight (ethnobotanical doses) of G. latifolium orally daily. On the 14th day, the animals were sacrificed and different antihyperglycaemic parameters were evaluated as well as its related gene expressions. Results: Diabetic rats administered three doses of aqueous extract of G. latifolium significantly (p < 0.05) lowered the fasting blood glucose, glycated haemoglobin, serum lipid profiles, lipid peroxidation (5.62-1.2 μ/mg protein) levels, as well as gene expression of glucose-6-phosphatase in alloxan-induced diabetic rats. There was a significant (p < 0.05) increase in the liver glycogen content (16.23-112.5 mg glucose/2 g), antioxidant enzymes activities, glucose transporter (GLUT-2 and GLUT-4) levels and relative gene expression of hexokinase in diabetic rats administered different doses of aqueous extract of G. latifolium. Discussion and conclusions: It can be deduced that the aqueous extract of G. latifolium leaf at these doses may be useful in managing diabetes mellitus and its associated complications. Therefore, this extract may be a potent antidiabetic agent in clinical therapy in the future.

[PMID: 30976694 PMCID: PMC6441794 DOI: 10.1016/j.heliyon.2019.e01421] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2018] [Revised: 02/19/2019] [Accepted: 03/21/2019] [Indexed: 12/11/2022] Open
Abstract
Diabetes mellitus is a major public health problem in Morocco. The value of ethnobotanical information is now increasingly acknowledged. To inventory and to provide ethnobotanical information on some of the medicinal plants used in traditional medicine to treat diabetes in Rabat (Morocco), a survey was undertaken from March 1st to April 30th 2018. This survey was conducted using a semi-structured questionnaire targeting diabetic patients from the SOS Diabetes Center. 334 diabetic patients were interviewed. Of this group, 53.6% (34 men and 145 women) use medicinal plants to control their diabetes. 47.2% have type 2 diabetes and 52.5% have type 1diabetes. Thirty plant species belonging to 18 botanical families were recorded for the treatment of diabetes. The most represented families were Lamiaceae with 8 species followed by Fabaceae with 3 species. Based on the highest number of users, the most important species were Trigonella foenum-graecum L. (15.4%), Salvia officinalis L. (13.3%) and Olea europaea L. (10.8%). Leaves (47.5%), seeds (20.2%) and stem (17.6%) were the parts predominantly used to prepare the formulations, which were mainly infusions (50.9%), administrated by the oral route (98.9%). Some plants were used only by type 1 diabetics while others were used by type 2 diabetics. The observed adverse events related to the use of medicinal plants were represented by occasional heartburn in 2.2% of diabetic patients. This study is the first to collect and document information on medicinal plants and how they are used by diabetic patients. Calamintha alpina L. is reported for the first time at the international level as used in traditional treatment of diabetes and seven others were reported as new medicinal plants used to treat diabetes in Morocco. This will extend the list of plants already mentioned as used for diabetes. Further research should be carried out to validate the antidiabetic uses of most of these plant species.
