[PMID: 34657540 DOI: 10.1080/13813455.2021.1987478] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 09/22/2021] [Accepted: 09/24/2021] [Indexed: 12/15/2022]
Abstract
CONTEXT The molecular mechanism by which Swertiamarin (SM) prevents advanced glycation end products (AGEs) induced diabetic nephropathy (DN) has never been explored. OBJECTIVE To evaluate the effect of SM in preventing the progression of DN in high fat diet-streptozotocin-induced diabetic rats. MATERIALS AND METHODS After 1 week of acclimatisation, the rats were divided randomly into five groups as follows: (1) Control group, which received normal chow diet; (2) High-fat diet (HFD) group which was fed diet comprising of 58.7% fat, 27.5% carbohydrate and 14.4% protein); (3) Aminoguanidine (AG) group which received HFD + 100 mg/k.b.w.AG (intraperitoneal); (4) Metformin (Met) group which received HFD + 70 mg/k.b.w. the oral dose of Met and (5) SM group which was supplemented orally with 50 mg/k.b.w.SM along with HFD. After 12 weeks all HFD fed animals were given a single 35 mg/k.b.w. dose of streptozotocin with continuous HFD feeding for additional 18 weeks. Later, various biochemical assays, urine analyses, histopathological analysis of kidneys, levels of AGEs, expression of various makers, and in-silico analysis were performed. RESULTS The diabetic group demonstrated oxidative stress, increased levels of AGEs, decreased renal function, fibrosis in the renal tissue, higher expression of the receptor for advanced glycation end products (RAGE), which were ameliorated in the SM treated group. In-silico analysis suggests that SM can prevent the binding of AGEs with RAGE. CONCLUSIONS SM ameliorated DN by inhibiting the oxidative stress induced by AGEs.HighlightsSM reduces the levels of hyperglycaemia-induced advanced glycation end products in serum and renal tissue.SM prevents renal fibrosis by inhibiting the EMT in the kidney tissue.The in-silico analysis proves that SM can inhibit the binding of various AGEs with RAGE, thereby inhibiting the AGE-RAGE axis.

Abstract
As a progressive neurological disease with increased morbidity and mortality, Alzheimer Disease (AD) is characterized by neuron damage that controls memory and mental functions. Enicostema axillare (EA), an herb with a history of combativeness and effectiveness in treating Rheumatoid Arthritis, Cancer, and Diabetes, is used in Indian folk medicine from a holistic point of view. Though the herb is used for many illnesses, the molecular mechanism of its bioactive on AD has not been deciphered by intricate research. A unique pharmacology approach based on ADME drug screening and targeting, pathway enrichment (GO and KEGG), and network pharmacology, was established to explore the molecular mechanisms of E. axillare (EA) bioactive compounds for the treatment of AD. In brief, we bring to light the three active compounds of EA and seven potential molecular targets of AD, which are mainly implicated in four signaling pathways, i.e., MAPK, Apoptosis, neurodegeneration, and the TNF pathway. Moreover, the network analysis of the active compounds, molecular targets, and their pathways reveals the pharmacological nature of the compounds. Further, molecular docking studies were carried out to explore the interactions between the EA bioactive compounds and the targets and examine the binding affinity. The outcome of the work reflects the potential therapeutic effects of the compounds for treating AD through the modulation of the key proteins, which further corroborates the reliability of our network pharmacology analysis. This study not only helps in understanding the molecular mechanism of the drugs but also helps in finding and sorting new drugs for the treatment of AD, and other complex diseases through modern medicine.

Abstract
Traditional uses for the plant Medicago sativa (M. sativa) (Alfalfa) (Family: Fabaceae) include liver protection, antioxidant activity, and the treatment of bleeding and digestive issues. This study aims to assess the effect of ethanol extract of M. sativa (EEMS) on experimental-induced ulcers in diabetic rats. By pylorus ligation and ethanol administration, gastric ulcers were induced in diabetic rats. Five groups each consisting of six rats in each model were used. All other groups except Group I were made diabetic by giving rats alloxan (140 mg/kg i.p.). Vehicles were given to Group I (normal control) and Group II (diabetes control) rats. Group III (positive control) received ranitidine 50 mg/kg, and Group IV and V received EEMS at doses of 100 and 400 mg/kg, respectively. In the pylorus ligation and ethanol-induced stomach ulcer model of rats, the findings demonstrated that EEMS (100 mg/kg) showed a decreased ulcer index of 2.01 ± 0.41 and was found statistically significant against the diabetes control group (p < 0.001) as well as, an ulcer index of 0.68 ± 0.22 by EEMS (400 mg/kg) with a significant reduction in the ulcer index (p < 0.001). EEMS (100 and 400 mg/kg) reduce free acidity by 13.16 ± 0.65 mEq/L and 9.83 ± 0.30 mEq/L, respectively. EEMS also showed a protective impact on the liver and kidneys of diabetic rats. Antihyperglycemic action was also discovered in diabetic animals. The findings of the current investigation demonstrated that ethanolic extract of M. sativa possesses anti-ulcer activity in diabetic rats. Ethanolic extract of M. sativa may be a treatment option for stomach ulcers that also have diabetes.

Int J Biol Macromol 2023; 240:124445. [PMID: 37060982 DOI: 10.1016/j.ijbiomac.2023.124445] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 03/21/2023] [Accepted: 04/10/2023] [Indexed: 04/17/2023]
Abstract
Diabetes is a highly complex disease that has an adverse impact on the lives of individuals, and the current medicines used to manage diabetes have obvious side effects. Medicinal plants, on the other hand, may serve as an alternate source of anti-diabetic drugs. A polyherbal combination has a higher and more extensive therapeutic potential than a single herb. Yet, due to deterioration during the absorption process, the usage of this drug still yields inadequate results. Encapsulation of polyherbal drug with chitosan nanoparticles is one of the key ways to solve this problem due to its biocombatibilty, slow and targeted drug delivery characteristics. In the present study, the chitosan was derived from prawn shell and the chitosan nanoparticles had been prepared by ionic-gelation method. The anti-diabetic polyherbal drug (Andrographis paniculata, Andrographis alata, Adhatoda zeylanica, Gymnema sylvestre, Syzygium cumini, and Justicia glabra) was encapsulated with a bio-derived chitosan biopolymer. The drug loading efficiency was about 85 %. The chemical and physical properties of the chitosan and drug-loaded chitosan nanoparticles had been analyzed by FT-IR absorption, XRD, SEM, TEM and EDAX analysis. The antidiabetic efficiency, hepatoprotective activity and antihyperlipedimic activity of the chitosan nanoparticles, polyherbal drug and polyherbal drug encapsulated with chitosan nanoparticles were assessed in a group of rats. The polyherbal drug reduced the serum glucose level from 306.4 mg/dL to 134.47 mg/dL, while the polyherbal drug encapsulated with chitosan nanoparticles reduced to 127.017 mg/dL. This was very close to the serum glucose level of non-diabetic rat (124.65 mg/dL). Further, it considerably increased the insulin level close to that of non-diabetic rat. Thus, the polyherbal drug encapsulated with chitosan nanoparticles showed superior efficiency in antidiabetic and also diabetic complications.

Antihyperglycemic Potential of Spondias mangifera Fruits via Inhibition of 11β-HSD Type 1 Enzyme: In Silico and In Vivo Approach. J Clin Med 2023; 12:jcm12062152. [PMID: 36983154 PMCID: PMC10051293 DOI: 10.3390/jcm12062152] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Revised: 02/11/2023] [Accepted: 02/15/2023] [Indexed: 03/12/2023] Open
Abstract
The 11 β- hydroxysteroid dehydrogenase 1 (11 β-HSD1) is hypothesized to play a role in the pathogenesis of type 2 diabetes and its related complications. Because high glucocorticoid levels are a risk factor for metabolic disorders, 11β-HSD1 might be a viable therapeutic target. In this investigation, docking experiments were performed on the main constituents of Spondias mangifera (SM) oleanolic acid, β-amyrin, and β-sitosterol to ascertain their affinity and binding interaction in the human 11β-hydroxysteroid dehydrogenase-1 enzyme’s active region. The results of in vitro 11β HSD1 inhibitory assay demonstrated that the extract of S. mangifera had a significant (p < 0.05) decrease in the 11-HSD1% inhibition (63.97%) in comparison to STZ (31.79%). Additionally, a non-insulin-dependent diabetic mice model was used to examine the sub-acute anti-hyperlipidemic and anti-diabetic effects of SM fruits. Results revealed that, in comparison to the diabetic control group, SM fruit extract (SMFE) extract at doses of 200 and 400 mg/kg body weight considerably (p < 0.05 and p < 0.01) lowered blood glucose levels at 21 and 28 days, as well as significantly decreased total cholesterol (TC) and triglycerides (TG) and enhanced the levels of high-density lipoprotein (HDL). After 120 and 180 s of receiving 200 and 400 mg/kg SMFE, respectively, disease control mice showed significantly poorer blood glucose tolerance (p < 0.05 and p < 0.01). SMFE extract 200 (p < 0.05), SMFE extract 400 (p < 0.01), and Glibenclamide at a dosage of 5 mg/kg body weight all resulted in statistically significant weight increase (p < 0.01) when compared to the diabetic control group after 28 days of treatment. According to in silico, in vitro, and in vivo validation, SMFE is a prospective medication with anti-diabetic and hypoglycemic effects.

Abstract
OBJECTIVES Madhumeha Kusumakar Rasa (MKR) is an Ayurved formulation having a strong pharmacological base for diabetes management. This study aimed to validate MKR's efficacy in dexamethasone-induced insulin resistance (IR). METHODS Albino Wistar rats were divided into four groups. Group 1 served as the normal control, Group 2 received dexamethasone 1.5 mg/kg (i.p.), Group 3 received dexamethasone and metformin 200 mg/kg (p.o.), and Group 4 received dexamethasone and MKR 236 mg/kg (p.o.). Animals were evaluated for serum glucose levels and glucose tolerance, serum insulin, Homeostatic model assessment of insulin resistance (HOMA-IR), Homeostatic model assessment of insulin sensitivity (HOMA-IS), fasting glucose to insulin ratio (FGIR), and lipid parameters. Pancreas, liver, and kidneys were evaluated for reduced Glutathione (GSH) and Malondialdehyde (MDA) levels. These tissues were also evaluated for histopathological changes. RESULTS MKR showed significant improvement in serum glucose and glucose tolerance, serum insulin and HOMA-IR, HOMA-IS, and FGIR. It also showed a significant improvement in lipid parameters as compared to the dexamethasone-treated group. It prevented depletion of GSH levels and elevation in MDA levels. These effects were supported by histopathological analysis. CONCLUSIONS MKR treatment significantly attenuated dexamethasone-induced IR. This study validates the mechanism of the anti-diabetic potential of MKR.

Abstract
Glucokinase (GK) is an enzyme involved in synthesising glucose into glucose-6 phosphate and serves a crucial function in glucose sensing. Therefore, agents that induce GK activation could be used to treat T2DM. The present work has been carried out to investigate the GK activation potential of phytoconstituents of Enicostemma littorale through molecular docking. All the phytoconstituents have been screened through the Lipinski rule of 5, Veber's rule, and ADMET properties. From these initial screening, only Apigenin, Ferulic acid, Genkwanin, p-coumaric acid, Protocatechuic acid, Syringic acid, and Vanillic acid have been selected to perform molecular docking studies. The binding free energy and binding mode of the native ligand in the allosteric site of the enzyme have been considered the reference for the other molecules' validation. The native ligand has exhibited - 7.2 kcal/mol binding free energy, whereas; it has formed four hydrogen bonds with THR-228, LYS-169, ASP-78, and GLY-81. Based on these findings, the interactions of phytoconstituents have been justified. Apigenin, genkwanin, and swertiamarin exhibited - 8.7, - 7.5, and - 8.3 kcal/mol binding free energy, respectively, which indicates better enzyme activation than the native ligand. Swertiamarin has formed 08 hydrogen bonds with allosteric amino acid residues, which confirms the excellent enzyme activation by these phytoconstituents. We concluded that if we can isolate and consume the exact active phytoconstituents (GK activators) from this plant, we can use them effectively to treat T2DM. More GK activators can be developed by considering them as a natural lead moiety.

Abstract
BACKGROUND All parts of Momordica charantia L. have potential hypoglycemic properties in reversing the metabolic disorder of diabetes mellitus. However, there exists a need for preparing an effective and safer formulation of active phytochemicals. We have also reviewed and analyzed certain patents on such preparatory methods for Momordica charantia L. formulations. OBJECTIVE This study aimed to isolate essential oil from the seeds of Momordica charantia L., analyze its phytochemicals, and study their anti-diabetic effects. METHODS The essential oil was isolated by the hydrodistillation method and analyzed for phytochemicals by GC-MS. Furthermore, its acute toxicity was tested in rats. Anti-diabetic effects were evaluated in Streptozotocin-induced diabetic rats with 17.5 and 55 mg/kg b.wt of essential oil by evaluating blood glucose, serum lipid profile, liver glycogen, protein, and other serum markers such as ALT, AST, ALP, urea, and creatinine. The histologic changes in the liver, pancreas, and kidney were evaluated using Haematoxylin and Eosin staining. RESULTS The phytochemicals having hypoglycaemic and insulin induction potency were identified in the GC-MS analysis. A highly significant (p≤0.01; p≤0.001) reduction in blood glucose was observed from 17.5 mg/kg and 55 mg/kg essential oil treatments, respectively. Diabetes-associated metabolic alterations (p≤0.001) observed in diabetic control rats such as lipid profile, enzymes, glycogen, protein, urea, and creatinine were normalized upon treatment with essential oil. Moreover, the histologic changes in vital organs reversed in treated rats. CONCLUSION The essential oil of Momordica charantia L. seed has promising potency to normalize the metabolic changes of type II diabetes mellitus.

Abstract
Increased blood glucose in diabetic individuals results in the formation of advanced glycation end products (AGEs), causing various adverse effects on kidney cells, thereby leading to diabetic nephropathy (DN). In this study, the antiglycative potential of Swertiamarin (SM) isolated from the methanolic extract of E. littorale was explored. The effect of SM on protein glycation was studied by incubating bovine serum albumin with fructose at 60 °C in the presence and absence of different concentrations of swertiamarin for 24 h. For comparative analysis, metformin was also used at similar concentrations as SM. Further, to understand the role of SM in preventing DN, in vitro studies using NRK-52E cells were done by treating cells with methylglyoxal (MG) in the presence and absence of SM. SM showed better antiglycative potential as compared to metformin. In addition, SM could prevent the MG mediated pathogenesis in DN by reducing levels of argpyrimidine, oxidative stress and epithelial mesenchymal transition in kidney cells. SM also downregulated the expression of interleukin-6, tumor necrosis factor-α and interleukin-1β. This study, for the first time, reports the antiglycative potential of SM and also provides novel insights into the molecular mechanisms by which SM prevents toxicity of MG on rat kidney cells.

Abstract
Abstract
Background
The spices, cinnamon and turmeric have both culinary and pharmaceutical applications. Earlier studies proved their effect on reducing the symptoms associated with type 2 diabetes, a major lifestyle disease affecting millions world over. In our work, we prepared a bi-herbal extract of cinnamon and turmeric and studied its effect to alleviate the symptoms of type 2 diabetes in rat model.
Method
The phenolic rich bi-herbal extract was given to diabetes induced male wistar rats for 28 days at two different concentrations (50 and 150 mg/Kg bwt.). The changes in blood glucose level were monitored at weekly interval. At the end of the experiment, blood serum was collected and used for the estimation of lipid profile, Glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), Total Protein (TP), Albumin, Urea and Creatinine levels.
Result
The serum analysis revealed that administration of the bi-herbal extract at 150 mg/Kg bwt. significantly reduced the blood glucose level (152.60 ± 40.2 mg/dL; p < 0.05) of diabetic animals as compared to diabetic control (335.40 ± 67.3 mg/dL; p < 0.05) at the end of 4 weeks. The treatment also resulted in the reduction of total cholesterol and LDL-cholestrol levels as compared to diabetic control animals. The histopathological examination of tissues showed the improvement in pancreatic architecture and restoration of tissue integrity in liver and kidney.
Conclusion
The study concludes that methanol extract of combination of cinnamon and turmeric has good hypoglycemic, hypolipidemic and organ protective potential in diabetic rats which could be developed into functional food supplementation for the prevention of type 2 diabetes.

Abstract
Diabetes mellitus has developed into one of the debilitating diseases disturbing the health of many people living with cardiovascular diseases in modern times. The root of Ageratum conyzoides was investigated for its effects on alloxan-induced diabetic Wistar rats' cardiac tissues. Thirty-two (32) Wistar rats weighing between 180 and 190 g were randomly divided into four groups. The animals in groups B-D were induced with a single dose of 150 mg/kg body weight of alloxan (ALX) intraperitoneally. They were confirmed hyperglycemic after 72 hours of induction and then sustained in hyperglycemic condition for 2 weeks. Animals in groups C and D received AC intervention, as stated above, for four weeks. The body weight of the experimental animals and blood collection for glucose estimation were taken weekly for six weeks using appropriate instruments. Biochemical assays for lipid profile, antioxidant enzymatic, and nonenzymatic markers were carried out. Histopathological changes in the cardiac tissues were also studied. Administration of 150 mg/kg of ALX to experimental rats induced diabetes and significantly reduced the body weights, significantly (p < 0.05) increased the glucose level, triglyceride (TG), total cholesterol (TC), and low-density lipoprotein (LDL) levels, and decreased the levels of high-density lipoprotein (HDL) and antioxidant enzymatic markers such as catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx) while the antioxidant nonenzymatic marker such as malondialdehyde (MDA) level was significantly increased. By contrast, rats given the ethanolic extract root of A. conyzoides had significantly (p < 0.05) increased the body weight gain, whereas the glucose levels significantly (p < 0.05) improved in treated diabetic rats. This extract also improved the cardiovascular system of the diabetic rats by significantly decreasing TG and LDL levels, significantly (p < 0.05) increasing the HDL level, significantly reducing the cardiac contents of CAT, SOD, and GPx, and significantly (p < 0.05) decreasing MDA. Ethanolic extract root of A. conyzoides exhibited antihyperglycemic and antihyperlipidemic activities and mitigates damage to the heart from the ALX-induced myocardial toxicity associated with type-1 diabetes.

Abstract
The study was undertaken to evaluate the therapeutic effect of mustard oil incorporated diet in streptozotocin (STZ)-induced type 1 diabetic rats. Dietary composition has shown to play a significant role in improving insulin sensitivity. Various authors have reported the hypoglycemic effect of mustard oil in experimentally induced diabetic rats. In the present study, reverse transcriptase polymerase chain reaction (RT-PCR) was done to analyze the Glut 4 expression in STZ induced diabetic rats as it is a key player in glucose homeostasis. The effect of mustard oil on serum biochemical parameter and insulin levels was also studied. Twenty-four male Wistar rats were randomly divided into three different groups with each containing eight animals. The first, second and third groups were control, diabetic control and treatment group with mustard oil respectively. All the rats in respective groups were fed for 60 days with iso-caloric mash diet containing 8% lipid. Diabetes was induced by intra-peritoneal administration of STZ (40 mg/kg body weight). A highly significant reduction in blood glucose level, with an increase in insulin activity was observed in mustard oil-treated diabetic rats when compared to control group indicating anti-hyperglycemic activity of mustard oil. Mustard oil-treated diabetic rats showed increased expression of Glut 4 in muscle tissue when compared to diabetic control. A significant reduction in the levels of triacylglycerols, total cholesterol, VLDL and LDL and raised plasma HDL were noticed in mustard oil-treated diabetic rats when compared to diabetic control rats. Histopathological studies revealed a mild regeneration of β cells of pancreas in mustard oil-treated diabetic rats. The results from our investigation suggest that mustard oil elicits hypoglycemic effect by increased insulin activity and up-regulation of Glut 4 gene expression in muscle tissue of STZ-induced diabetic rats.

Abstract
Abstract
Background
Antidiabetic activity of aqueous root extract of Strophanthus hispidus (SHP) was evaluated based on its folklore used in traditional medicine for the treatment of diabetes. Objectives: This study aimed to investigate the in-vitro and in-vivo antidiabetic potential of the aqueous root extract of SHP.
Methods
SHP (50, 100 and 200 mg/kg p.o.), glibenclamide (5 mg/kg p.o.), normal saline (10 mL/kg; diabetic control) and distilled water (10 mL/kg; normal control) were administered once daily for 28 days, with the measurement of fasting blood glucose level at 7 days interval. Blood samples were collected on day 28 for serum biochemical (albumin, total protein [TP], creatinine, alanine transaminase [ALT], aspartate transaminase [AST], alkaline phosphatase [ALP], triglycerides [TG], total cholesterol [TC], high-density lipoprotein [HDL], low-density lipoprotein [LDL], bilirubin and urea) and hematological assays. The in-vitro antidiabetic activity was investigated using α-amylase and α-glucosidase enzymes inhibitory assays.
Results
SHP produced a day-dependent reduction in glucose level. Peak reduction (82.94 %; p < 0.05) was produced at the dose of 100 mg/kg. SHP significantly (p < 0.05) increased the level of HDL and TP but significantly (p < 0.05) reduced the levels of TG, LDL, TC, AST, ALT, ALP, bilirubin, creatinine and urea compared with diabetic control rats. Furthermore, SHP significantly (p < 0.05) increased the level of catalase, superoxide dismutase and reduced glutathione compared to diabetic control rats. SHP significantly (p < 0.05) inhibited α-amylase and α-glucosidase enzymes compared with acarbose.
Conclusion
The findings in this study showed that SHP possesses beneficial antidiabetic activity.

Abstract
BACKGROUND Sulphonylureas are the oldest and commonly used to treat diabetic patients, but its efficacy declines by time. It was reported that quinazoline nucleus exhibits a potent hypoglycemic effect in diabetic animal models. OBJECTIVE The current study aimed to synthesize new quinazoline-sulfonylurea conjugates and evaluate their hypoglycemic effects in alloxan-induced diabetic rats. METHODS The conjugates were synthesized by bioisosteric replacement of 5-chloro-2-methoxybenzamide moiety in glibenclamide or 1,3-dioxo-3,4-dihydroisoquinoline moiety in gliquidone with 6,7-dimethoxy-4-oxoquinazoline moiety (compounds 4a-4d, 9b-9c and 10b-10d). Diabetes was induced in rats by a single i.p. administration of alloxan, followed by treatment with the synthesized conjugates (5mg/kg Body weight). RESULTS All conjugates showed hypoglycemic effects with different efficacy indicated by the reduction in blood glucose and elevation of insulin levels. Moreover, these conjugates up-regulated the expression of pancreatic glucose transporter 2, muscle glucose transporter 4, and insulin receptor substrate-1 genes, compared to the diabetic group. A normal pancreatic tissue pattern was noticed in diabetic rats treated with compounds 9b, 9c, and 10c. CONCLUSION Conjugation of sulfonylurea with quinazoline (especially 9b, 9c, 10c) possessed a significant hypoglycemic effect through improving blood insulin level and insulin action and consequently increased the glucose uptake by the skeletal muscles.

Abstract
Lannea edulis (Sond.) Engl. commonly known as wild grape is used traditionally for the treatment of diabetes. It is only found in Eastern and Southern Africa. Phytochemical screening, antihyperglycemic and antihyperlipidemic effects of aqueous extracts of L. edulis in alloxan induced diabetic rats were carried out. We report herein the findings of this research work. Lannea edulis crude aqueous extracts were obtained by hot infusion and evaporation method. Phytochemical screening was carried out and subsequently toxicity studies of the aqueous extracts were performed to establish the Lethal Dose 50 (LD50) in albino rats. Alloxan monohydrate was used to induce diabetes in the rats. Lannea edulis positive control group doses of 100, 300, and 500 mg/kg were administered to 3 groups for 14 days. The positive control group was administered 5 mg/kg of glibenclamide. The negative and normal control groups were administered distilled water. To determine fasting blood glucose, blood was drawn on days 0, 1, 3, 5, 7, and 14 while it was drawn on days 0 and 14 for the determination of lipids. Phytochemical screening revealed the presence of flavonoids, saponins, tannins, cardiac glycosides, alkaloids and steroids. L. edulis diabetic positive control groups showed significant (P < 0.05) dose dependent reductions in fasting blood glucose levels. When day 0 mean blood glucose levels were compared to day 3 mean blood glucose levels of their respective groups, the 300 mg/kg L. edulis group showed a 23.3% drop and the 500 mg/kg L. edulis group showed a 52.6% drop. The 100 mg/kg L. edulis diabetic positive control group showed a 25.1% drop by day 5, the day on which it showed statistical significance (P < 0.05) compared to the diabetic control. In addition, administration of aqueous extracts of L. edulis to diabetic rats for 14 days significantly decreased (P < 0.05) the levels of serum total cholesterol, triglycerides, Low Density Lipoprotein (LDL) and Very Low Density Lipoprotein (VLDL) whilst increasing the levels of High Density Lipoprotein (HDL), when compared to the diabetic control group. It was concluded that L. edulis showed significant and dose dependent antihyperglycemic and antihyperlipidemic effects thus confirming its traditional use.

Intergenerational Influence of Paternal Obesity on Metabolic and Reproductive Health Parameters of the Offspring: Male-Preferential Impact and Involvement of Kiss1-Mediated Pathways.

Abstract
Obesity and its comorbidities are reaching epidemic proportions worldwide. Maternal obesity is known to predispose the offspring to metabolic disorders, independently of genetic inheritance. This intergenerational transmission has also been suggested for paternal obesity, with a potential negative impact on the metabolic and, eventually, reproductive health of the offspring, likely via epigenetic changes in spermatozoa. However, the neuroendocrine component of such phenomenon and whether paternal obesity sensitizes the offspring to the disturbances induced by high-fat diet (HFD) remain poorly defined. We report in this work the metabolic and reproductive impact of HFD in the offspring from obese fathers, with attention to potential sex differences and alterations of hypothalamic Kiss1 system. Lean and obese male rats were mated with lean virgin female rats; male and female offspring were fed HFD from weaning onward and analyzed at adulthood. The increases in body weight and leptin levels, but not glucose intolerance, induced by HFD were significantly augmented in the male, but not female, offspring from obese fathers. Paternal obesity caused a decrease in luteinizing hormone (LH) levels and exacerbated the drop in circulating testosterone and gene expression of its key biosynthetic enzymes caused by HFD in the male offspring. LH responses to central kisspeptin-10 administration were also suppressed in HFD males from obese fathers. In contrast, paternal obesity did not significantly alter gonadotropin levels in the female offspring fed HFD, although these females displayed reduced LH responses to kisspeptin-10. Our findings suggest that HFD-induced metabolic and reproductive disturbances are exacerbated by paternal obesity preferentially in males, whereas kisspeptin effects are affected in both sexes.

Abstract
BACKGROUND Swertiamarin, is a secoiridoid glycoside found in genera of Enicostemma Species (Enicostemma littorale and Enicostemma axillare) belonging to the family of gentianaceae, which has been reported to cure many diseases such as diabetes, hypertension, atherosclerosis, arthritis, malaria and abdominal ulcers. However, to the best of our knowledge, till date systematic studies to understand the molecular basis of cardiac and metabolic disease preventing properties of swertiamarin has not been reported. AIM OF THE REVIEW The present review aims to compile an up-to-date information on the progress made in the protective role of swertiamarin in cardiac and metabolic diseases with the objective of providing a guide for future research on this bioactive molecule. MATERIALS AND METHODS Information on the swertiamarin was collected from major scientific databases (Pubmed, Springer, google scholar, and Web of Science) for publication between1974-2016. In this review, the protective role of swertiamarin on cardiac and metabolic diseases was discussed. RESULTS Swertiamarin reported to exhibit a wide range of biological activities such as anti-atherosclerotic, antidiabetic, anti-inflammatory and antioxidant effects. These activities were mainly due to its effect on various signaling pathways associated with cardiac remodeling events such as inhibition of NF-kB expression, LDL oxidation, apoptosis, inflammatory and lipid peroxidation markers and stimulation of antioxidant enzymes. CONCLUSION Sweriamarin exhibit a wide range of biological activities. This review presents evidence supporting the point of view that swertiamarin should be considered a potential therapeutic agent against cardiac and metabolic diseases, giving rise to novel applications in their prevention and treatment.

Antidiabetic drugs, with varied mode of action, are although available, apprehensions exist for their limited action or side effects upon prolonged use. Efforts are therefore inclined toward finding other alternatives. The present study was, thus, undertaken to evaluate the cardioprotective effect of Azadirachta indica (AI) on microangiopathic changes in rat model of diabetes. MATERIALS AND METHODS Diabetes was induced in male rats by single intraperitoneal injection of streptozotocin (60 mg/kg body weight). Seven days after glucose levels are stabilized, aqueous leaf extract of AI (ALE) (600 mg/kg(1) body weight) was administered orally to diabetic animals every day for 7 days. RESULTS High blood glucose characterizing diabetes in these animals was found to show increased lipid peroxidation (LPO), altered antioxidant biomarkers together with microangiopathic alterations. The treatment of diabetic rats with ALE reduced the levels of blood glucose, LPO, and restored the activities of antioxidant enzyme. Light and transmission electron microscopic analysis revealed reduced necrotic areas and inflammation in tissue architecture of ALE treated heart in comparison to untreated diabetic group. CONCLUSION AI provides cardioprotection by ameliorating oxidative stress in rat model of diabetic mellitus. SUMMARY The streptozotocin (STZ) treatment (60 mg/kg body weight) to animals induced diabetic changes such as elevated blood glucose levels, decreased body weight, altered lipid profiles together with development of proxidant state evidenced by elevated levels of lipid peroxidation (LPO), depletion in reduced glutathione (GSH) levels and altered antioxidant enzymes with consequent microangiopathic alterations in heart tissue evinced by localization of necrotic and inflamed areas in heart tissueThe treatment of animals with Azadirachta indica leaf extract (ALE) (600 mg/kg body weight) post-STZ treatment significantly reversed the adverse effects witnessed by normalized blood glucose levels, improvement in reduced body weight and stabilized lipid profilesFurther, ALE treatment also significantly reduced the LPO indices, improvement in GSH content and restoration of antioxidant enzyme activities, suggesting antioxidatant potential of ALEThe microangiopathic changes in the heart tissue consequent to induction of diabetes and oxidative stress by STZ as reiterated through light microscopy and transmission electron microscopy were found to be reversed by ALE treatment. These observations pointed toward cardiopreventive effects of ALE following microangiopathic changes as seen following induction of diabetes mellitus.

Abstract
Oral cancer is one of the most common malignancies worldwide, and India has recorded the highest annual incidence of oral cancer in comparison with other countries. Altered lipid peroxidation and antioxidant status along with defect in detoxification cascade have been implicated in the pathogenesis of several cancers including oral cancer. The aim of this study was to investigate the chemopreventive potential of ethanolic extract of Enicostemma littorale leaves (ElELet) in 7,12-dimethylbenz(a)anthracene (DMBA)-induced hamster buccal pouch carcinogenesis. Oral tumor was developed in the buccal pouches of male golden Syrian hamsters by painting with 0.5% DMBA three times a week for 14 weeks. We observed 100% tumor formation with increase in tumor volume and tumor burden in the hamsters treated with DMBA alone. Imbalance in phase I (cytochrome P450 and cytochrome b5) and phase II (glutathione reductase, glutathione- S-transferase, glutathione, and Deoxythymidine-diaphorase (DT)-diaphorase) detoxification agents and lipid peroxidation by-products (thiobarbituric acid reactive substances) and antioxidant (superoxide dismutase, catalase, glutathione peroxidase, and vitamins E and C) status was noticed in hamsters treated with DMBA alone. Oral administration of ElELet at a dose of 250 mg/kg body weight to hamsters treated with DMBA significantly prevented both precancerous and cancerous lesions in the oral cavity. ElELet modulated the status of phase I and II detoxification agents and antioxidants in favor of the suppression of oral carcinogenesis. This study thus suggests that E. littorale might have inhibited the oral carcinogenesis in DMBA-treated hamsters through its antioxidant potential. The present findings are also substantiated by histological studies during DMBA-induced oral carcinogenesis.

Abstract
OBJECTIVE To investigate the anti-diabetic and anti-cholesterolemic activity of methanol extracts of leaves of Amaranthus caudatus, Amaranthus spinosus and Amaranthus viridis in normal and streptozotocin (STZ) induced diabetic rats. METHODS In this study, the anti-diabetic and anti-cholesterolemic activity of methanol extracts of leaves of all three plants was evaluated by using normal and STZ induced diabetic rats at a dose of 200 mg/kg and 400 mg/kg p.o. daily for 21 days. Blood glucose levels and body weight were monitored at specific intervals, and different biochemical parameters, serum cholesterol, serum triglyceride, high density lipoprotein, low density lipoprotein and very low density lipoprotein were also assessed in the experimental animals. Histology of pancreas was performed. RESULTS It was found that all the three plants at 400 mg/kg dose showed significant anti-diabetic and anti-cholesterolemic activity (P<0.01), while at 200 mg/kg dose less significant anti-diabetic activity (P<0.05) was observed. CONCLUSIONS Methanol extracts of Amaranthus caudatus, Amaranthus spinosus and Amaranthus viridis showed significant anti-diabetic and anti-cholesterolemic activity, which provides the scientific proof for their traditional claims.

Abstract
Background: Bioflavonoids are well known for their multi directional biologic activity including antidiabetic effect. It has been demonstrated that flavonoids can act as insulin secretagogue or insulin mimetic agents. Objectives: This experimental study was designed in Arak University of Medical Sciences, Arak, Iran, to investigate the effects of biochanin A (a bioflavonoid) on fasting blood glucose (FBG), body weight, glycosylated hemoglobin (HbA1c), lipid profile, serum enzymes, and visfatin of streptozocin-induced diabetic rats. Patients and Methods: We used 24 male Wistar rats and randomly allocated them to four groups of six rats. One group was randomly assigned as control and diabetes was induced in three other groups by administration of streptozocin (35 mg/kg of body weight) intraperitoneally. The groups received the following treatments: group 1 (control), 5% DMSO; group 2 (diabetic control), 0.5% DMSO; and group 3 and 4, respectively 10 and 15 mg/kg biochanin A for 30 days. Body weight and biochemical parameters including FBG, HbA1c, lipid profile, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and visfatin were measured in all rats. Results: FBG level was significantly reduced in treated diabetic rats (139.8 ± 9.3 and 206 ± 11 mg/dL in groups 3 and 4, respectively) in comparison to the diabetic control (295.1 ± 14 mg/dL) (P < 0.05). Administration of biochanin A significantly decreased HbA1c in group 3 (6.66 ± 0.33) and group 4 (7.11 ± 0.31) in comparison to the diabetic control group (8.26 ± 0.44) (P < 0.05). Levels of serum visfatin were improved to near normal levels in the treated rats (249 ± 35.5 and 161.33 ± 13.07 in groups 3 and 4, respectively) in comparison to the diabetic control (302.17 ± 19.4) (P < 0.05). Furthermore, biochanin A showed a protective effect against weight loss in diabetic rats (P < 0.05). In treated rats, serum total cholesterol, triglyceride, and low-density lipoprotein cholesterol (LDL-c) were significantly decreased and high-density lipoprotein (HDL-c) was increased in comparison with the diabetic control group. In addition, biochanin A restored the altered plasma enzymes (AST, ALT, and ALP) activities to near normal. Histopathologic examination of the pancreas also indicated that biochanin A had protective effects on β-cells in streptozocin-induced diabetic rats. Conclusions: This study demonstrated that biochanin A possessed hypoglycemic and antilipemic activities and could increase visfatin expression, which suggests its beneficial effect in the treatment of diabetes.

Abstract
Medicinal plants are efficient ameliorator of oxidative stress associated with diabetes mellitus. In this study, ethyl acetate fraction (SCEE) of Sida cordata was investigated for scientific validation of its folk use in diabetes. Antidiabetic effect of SCEE was confirmed by antihyperglycemic activity in normal glucose loaded and diabetic glucose loaded animals as well as normal off feed animals. Confirmation of antidiabetic activity and toxicity ameliorative role of S. cordata was investigated in a chronic multiple dose treatment study of fifteen days. A single dose of alloxan (120 mg/kg) produced a decrease in insulin level, hyperglycemia, elevated total lipids, triglycerides, and cholesterol and decreased the high-density lipoproteins. Concurrent with these changes, there was an increase in the concentration of lipid peroxidation (TBARS), H2O2, and nitrite in pancreas, liver, and testis. This oxidative stress was related to a decrease in glutathione content (GSH) and antioxidant enzymes. Administration of SCEE for 15 days after diabetes induction ameliorated hyperglycemia, restored lipid profile, blunted the increase in TBARS, H2O2, and nitrite content, and stimulated the GSH production in the organs of alloxan-treated rats. We suggested that SCEE could be used as antidiabetic component in case of diabetes mellitus. This may be related to its antioxidative properties.

Abstract
OBJECTIVES To investigate the hepatoprotective, antioxidant and antihyperlipidemic effect of N-Trisaccharide isolated from Cucumis prophetarum (L.) on different experimental rats. METHODS N-Trisaccharide (25 and 50 mg/kg.b.w), silymarin (25 mg/kg) and glibenclamide (25 mg/kg) was orally administered once daily for 28 days and toxicity evaluation studies were carried out. Liver damage was assessed by determining DNA damage, serum enzyme activities and hepatic histopathology of carbon tetrachloride (CCl4) induced hepatic injury in rats. Enzymatic and non enzymatic antioxidant levels in liver and kidney were determined and biochemical parameters such as, serum lipid profile, renal function markers were estimated in type 2 diabetic rats. RESULTS DNA fragmentation analysis revealed the protective effect of N-Trisaccharide on liver DNA damage. Histopathological studies indicated that CCl4-induced liver injury was less severe in N-Trisaccharide (25 and 50mg/kg) treated group. Given at the above doses conferred significant protection against the hepatotoxic actions of CCl4 in rats, reducing serum markers like SGOT, SGPT, ALP, creatinine and urea levels back to near normal (p<0.05) compared to untreated rats. In diabetic rats, N-Trisaccharide treatment significantly reversed abnormal status of enzymatic and non-enzymatic antioxidants levels to near normal. Also, serum lipids such as TG, TC, LDL-C and VLDL-C levels were significantly (p<0.05) reduced compared to diabetic untreated rats. CONCLUSION Present study results confirm that N-Trisaccharide possesses significant antihyperlipidemic, antioxidant and hepatoprotective properties.

Abstract
Fenofibrate is a peroxisome proliferator-activated receptor-α that has been clinically used to treat dyslipidemia and insulin resistance. To better understand the molecular mechanisms underlying fenofibrate action, we investigated whether fenofibrate affects serum levels of vaspin, an adipocytokine that has recently been shown to link obesity and insulin resistance. Fenofibrate treatment significantly increased serum vaspin levels of dyslipidemic patients, which correlated with reduced body weight and increased insulin sensitivity. To elucidate the biochemical mechanisms of fenofibrate action, we investigated the effect of fenofibrate on vaspin mRNA and protein expressions in obese rats. Fenofibrate greatly increased vaspin mRNA and protein levels in visceral adipose tissue consisting of retroperitoneal, mesenteric, and periepididymal adipose tissue but not in the subcutaneous adipose tissue, which correlated with increased serum vaspin levels and increased insulin sensitivity in obese rats. Consistent with a direct effect on vaspin expression, fenofibrate treatment significantly increased the mRNA and protein expression levels of vaspin in 3T3-L1 adipocytes. Together, our results demonstrate for the first time that fenofibrate upregulates vaspin expression in dyslipidemic human subjects and suggest that upregulation of vaspin expression in adipocytes may provide a mechanism by which fenofibrate improves insulin sensitivity in dyslipidemic patients.

Abstract
Various extracts of flowers of Cassia fistula Linn (Leguminosae) such as petroleum ether (60-80°), chloroform, acetone, ethanol, aqueous, and crude aqueous extracts and two fractions of ethanol extract were tested for antihyperglycemic activity in glucose-overloaded hyperglycemic rats. The effective antihyperglycemic extracts and fraction were tested for their hypoglycemic activity at two dose levels, 200 and 400 mg/kg, respectively. To confirm their utility in higher models, the effective extracts and fraction of C. fistula were subjected to antidiabetic study in an alloxan-induced diabetic model at two dose levels, 200 and 400 mg/kg, respectively. Biochemical parameters like glucose, urea, creatinine, serum cholesterol, serum triglyceride, high-density lipoprotein, low-density lipoprotein, hemoglobin, and glycosylated hemoglobin were also assessed in experimental animals. The petroleum ether and ethanol extracts of C. fistula and the water-soluble fraction of ethanol extract were found to exhibit significant antihyperglycemic activity. The extracts, at the given doses, did not produce hypoglycemia in fasted normal rats, and the fraction exhibited weak hypoglycemic effect after 2 h of the treatment. Treatment of diabetic rats with ethanol extract and water-soluble fraction of this plant restored the elevated biochemical parameters significantly (P<0.05) to the normal level. No activity was found in the petroleum ether extract of the plant. Comparatively, the water-soluble fraction of ethanol extract was found to be more effective than the ethanol extract, and the activity was comparable with that of the standard, glibenclamide (5 mg/kg).

Abstract
OBJECTIVES Dyslipidemia in diabetes mellitus is a significant risk factor for the development of cardiovascular complications. The aim of this study was to evaluate the effect of the ethyl-acetate fraction of an ethanolic extract from Streospermum suaveolens on lipid metabolism in streptozotocin (STZ)-induced diabetic rats. METHODS Diabetes was induced by intraperitonial injection of STZ (50 mg/kg). Diabetic rats were treated with an ethyl-acetate fraction orally at doses of 200 and 400 mg/kg daily for 14 days. On the 15(th) day, serum lipid profiles, such as total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL), and high-density lipoprotein (HDL), were estimated in experimental rats. The atherogenic (AI) and the coronary risk (CRI) indices were also evaluated. RESULTS The ethyl-acetate fraction at doses of 200 and 400 mg/kg significantly (P< 0.001) and dose-dependently reduced serum cholesterol, triglycerides and LDL, but increased HDL towards near normal levels as compared to diabetic control rats. The fraction also significantly (P< 0.001) lowered the atherogenic index (AI) and coronary risk index (CAI) in a dose-dependent manner. CONCLUSION The present study demonstrated that the ethyl-acetate fraction of Stereospermum suaveolens exhibits a potent antihyperlipidemic activity in hyperglycemic rats and suggests that the plant may have therapeutic value in treating the diabetic complication of hyperlipidemia.

Abstract
Orthosiphon stamineus is a popular folk medicine widely used to treat many diseases including diabetes. Previous studies have shown that the sub-fraction of chloroform extract was able to inhibit the rise of blood glucose levels in a glucose tolerance test. This study was carried out to evaluate the chronic effect and possible mechanism of action of the bioactive chloroform sub-fraction of O. stamineus using streptozotocin-induced diabetic rats and in vitro methods. Administration of the chloroform extract sub-fraction 2 (Cƒ2-b) at a dose of 1 g/kg twice daily on diabetic rats for 14 days showed a significant lowering (p < 0.05) of the final blood glucose level compared to the pretreatment level. However, there were no significant differences in the plasma insulin levels post-treatment compared to the pretreatment levels for all doses of Cƒ2-b. Conversely, Cƒ2-b at a concentration of 2 mg/mL significantly increased (p < 0.001) the glucose uptake by the rat diaphragm muscle. The increase in glucose uptake was also shown when the muscle was incubated in a solution containing 1 IU/mL of insulin or 1 mg/mL of metformin. Furthermore, the effect of this sub-fraction on glucose absorption in the everted rat jejunum showed that Cƒ2-b at concentrations of 0.5 mg/mL, 1 mg/mL and, 2 mg/mL significantly reduced the glucose absorption of the jejunum (p < 0.05-0.001). Similarly, the absorption of glucose was also inhibited by 1 mg/mL and 2 mg/mL of metformin (p < 0.001). These results suggest that the effect of Cƒ2-b may be due to extra-pancreatic mechanisms. There was no evidence that the plant extract stimulated the release of insulin in order to lower the blood glucose level.

Abstract
The antidiabetic actions of Castanospermum australe Cunn., seed (CAS) extract were evaluated in Poloxamer-407 (PX-407) induced T2DM rats. The CAS extract (100 and 150 mg/kg body weight) was administered orally once a day for 5 weeks after the animals were confirmed diabetic. A significant increase in blood glucose, HbA₁c and serum insulin levels were observed in T2DM rats in comparison to citrate control rats. Treatment with CAS extract in T2DM rats reduced the elevated levels of blood glucose, HbA₁c and insulin with significant (p≤0.001) improvement in OGT. The CAS extract treatment also increased (p≤0.001) the K(ITT) and prevented increase in HOMA-R level in T2DM rats. The DPP-IV inhibitory potential of CAS extract showed IC₅₀ value of 13.96 μg/ml whilst the standard Diprotin A displayed the IC₅₀ value of 1.543 μg/ml. Molecular docking of the three reported alkaloids from the seeds of C. australe showed comparable DPP-IV inhibition with berberine. Our data suggest that CAS extract (150 mg/kg body weight) normalizes hyperglycemia in T2DM rats with strong DPP-IV inhibitory potential. The molecular docking showed that among the three alkaloids of seed extract 7-Deoxy-6-epi-castanospermine is a potent DPP-IV inhibitor similar to berberine.

Abstract
The solid dosage forms of Gymnemic acid nanoparticulate formulations developed earlier were tested for anti-diabetic activity and hypoglycemic activity. Glucose, insulin and various biochemical parameters were monitored from blood samples of rats to study the efficacy of these formulations. The nano-formulations exhibited significant anti-hyperglycemic activity and produced substantial hypoglycemia. Blood glucose levels (mg/dL) in glucose loaded hyperglycemic rats after dosing with Gymnemic acids nano-formulations were 79 to 98, as against 105 in the control after 3 hours. Hypoglycemic activity of Gymnemic acids nano-formulations ranged between 63 to 66 (Blood glucose concentration, mg/dL) as against 80 in the control. Biochemical parameters studied also supported the above observations. The study clearly shows that gymnemic acid nanoparticulate formulations developed may be a better therapeutic adjunctive option for diabetes mellitus in humans.

Abstract
Cassia fistula stem bark was used for the preparation of aqueous extract and synthesis of gold nanoparticles to evaluate the hypoglycemic effects of the plant. The synthesized gold nanoparticles were characterized by ultraviolet-visible spectroscopy for their absorbance pattern, Fourier transform infrared spectroscopy to identify possible functional groups, and scanning electron microscopy to determine the size of the nanoparticles. The present investigation reports the efficacy of the gold nanoparticles as promising in the treatment of hyperglycemia. Body weight, serum glucose concentrations, liver function tests, kidney function tests, and lipid profile were analyzed. A significantly larger decrease in serum biochemistry parameters and an increase in body weight, total protein levels, and high-density lipoprotein were observed in rats with streptozotocin-induced diabetes treated with gold nanoparticles than in the ones treated with the aqueous extract. The results of this study confirm that C. fistula gold nanoparticles have promising antidiabetic properties.
