Objective: One of the most prevalent diseases that significantly raise the global burden of disease is diabetes mellitus, which is linked to a number of secondary metabolic disorders. In this work, we designed and synthesized a novel series of α-aminophosphonate–coumarin hybrids as potential antidiabetic agents. Methods: The compounds were efficiently synthesized via a multicomponent Kabachnik–Fields reaction. Their structures were verified by spectral analysis (IR, NMR, MS), melting point determination, and TLC. An in silico docking study evaluating their binding capacity to the insulin receptor was performed using AutoDock Tools 1.5.4 to prepare the input files. Results and Discussion: Molecular docking suggested that compounds 4f, 4b, 4c, and 4e could act as potential antidiabetic templates. In vivo evaluation was conducted on a rat model of type II diabetes induced by streptozotocin (STZ) and nicotinamide (NA). Treatment with compounds 4f and 4b (30 mg/kg body weight) significantly and moderately suppressed fasting blood glucose levels, respectively, compared to diabetic controls. Furthermore, treatment with 4f and 4b dose-dependently reduced oxidative stress markers, including lipid peroxidation (MDA) and superoxide dismutase (SOD) activity, while increasing glutathione (GSH) levels in the pancreas and liver. Histological examination revealed that the architecture of liver and pancreatic tissues was less affected by 4f treatment compared to the diabetic control. Conclusions: The findings indicate that the synthesized coumarin–based α-aminophosphonates, particularly compound 4f, exhibit promising antioxidant and antihyperglycemic effects in a rat model of STZ-NA-mediated type II diabetes.

INTRODUCTION:The polyol pathway is responsible for the metabolism of almost one-third of the total glucose in people with chronic diabetes. Moreover, it causes complications in organs that rely on aldose reductase (AR) as an enzyme. The purpose of this research was to examine the in vitro and in vivo effects of a flavonoid-rich ethyl acetate fraction of a methanolic extract of Ficus carica Lam. leaves (FCEA) on the aldose reductase gene AKR1B1. The complicated relation of AR for target confirmation and analysis of the flavonoids of FCEA, quercetin, kaempferol, and chrysin was explored by building a flavonoid-protein complex network utilizing GeneCards®, String, and Cytoscape Networking. METHODS:The examination of ADMET was carried out after docking on the active sites of AR. By the binding and scoring abilities, the analysis was carried out. The ADMET characteristics demonstrated that these flavonoids had excellent solubility, absorption, and oral bioavailability, and the results demonstrate that they have potential. An additional in-vivo investigation was conducted on rats using a model induced by streptozotocin (STZ). Hence, upon induction, the rats' sciatic nerves were removed and prepared for an RT-PCR analysis of the AKR1B1 gene. RESULT:Compared to the diabetic normal group and the metformin group, rats treated with FCEA had lower levels of messenger RNA and AKR1B1 gene expression. CONCLUSION:This proves that FCEA has effectively blocked AR. It is highly likely to suggest FCEA as a potent aldose reductase inhibitor, as it considerably reduces the mRNA level of AKR1B1 gene expression in the sciatic nerve of sick rats, according to a combined bioinformatics prediction and RT-PCR analysis.

Background Colon cancer is the fourth leading cause of cancer deaths worldwide. The present study evaluated the chemopreventive effect of the combined treatment of Lactobacillus acidophilus, calcium citrate, and Moringa oleifera leaves extract against DMH (1,1-dimethylhydrazine hydrochloride) induced colon cancer. Material and methods Sprague Dawley rats were grouped into 10 different groups and treated with DMH 30 mg/kg s.c. for 8 weeks, Successful induction of colon cancer was confirmed with the help of symptoms, Individual and combined treatments of Lactobacillus acidophilus (109 cfu p.o.), calcium citrate (2 mg/kg p.o.) and Moringa oleifera (100 & 200 mg/kg p.o.) leaves extracts were used for 4 weeks. Result After 4 weeks of treatment, it was observed that a significant reduction in aberrant crypt foci (ACFs) count, whereas liver and kidney function, AST (aspartate transaminase), ALT (alanine transaminase), urea and creatinine biomarkers were retained in its normal range. Upon DMH treatment, liver tissue loses histoarchitecture with mononuclear cell infiltration, nuclear enlargement, and hyperchromasia, this reverts due to the combined treatment of Lactobacillus acidophilus (LA), calcium citrate (CC) and hydroalcoholic extract of Moringa oleifera leaves (ME). From the results, it was revealed that individual and combined treatment of Lactobacillus acidophilus, calcium citrate, and hydroalcoholic extract of Moringa oleifera leaves shows beneficial effects against the carcinogen. Conclusion Combined treatment of Lactobacillus acidophilus, calcium citrate, and hydroalcoholic extract of Moringa oleifera leaves showed positive effects against carcinogenesis and lowered aberrant crypt foci count and shows histoarchitectural improvements in liver histology with no nuclear enlargement and hyperchromasia in liver tissue.

Hematological malignancies for a very large percentage of cancers occurring the world over and lead to a very large number of deaths each year. It is not just the disease but also the currently available cure which are equally responsible for the side effects and discomfort experienced by the patients. The side effects of the current chemotherapeutic agents' available range from mouth ulcers, diarrhea, temporary hair loss, rashes, nausea, vomiting, and fatigue to low blood cell counts, increased risk of infections, graft versus host disease, tumor lysis syndrome, differentiation syndrome, and difficulty in conceiving. Due to these myriad side effects researchers and on a continuous lookout for newer treatment alternatives. For most developing countries one of the most attractive options is offered by herbals or plant-based medicines. One such herb is Cyclea peltata. It is a climbing shrub found aplenty in southern and eastern India. It has been used traditionally to cure lots of minor ailments. This paper explores the possibility of using the root extract for the treatment of leukemia. To do this, the extracts of the roots were prepared in different organic solvents to ensure complete extraction of all phytoconstituents fractions. The extracts were then tested on 3 different human cell lines. The potential cause of the antileukemic potential of the plant was also hypothesized and proven by carrying out antioxidant studies using the DPPH free radical scavenging assay. The probable active constituents were identified using the liquid chromatography-mass spectrometry assessment, wherein the responsible fractions were successfully identified. The studies showed that the alkaloid and phenolic phytoconstituents were responsible for the antileukemic potential via their antioxidant activity. This lays down the groundwork of offering a new and safer treatment option that could be further explored to be made into one having actual clinical outreach.

Objective: The objective of the study is to study the anti-hyperglycemic potential of Ethyl Acetate dissolved fraction of methanolic extract of Achyranthes aspera Linn. (EAAA) leaves on STZ induced diabetic rat model. Materials and Methods: Safety study of EAAA was carried out with different doses up to 2000 mg/kg. Hyperglycemia was developed in Sprague Dawley male (SD) rats by only one dose of streptozotocin 55 mg/kg in 0.1 M Citrate buffer by intraperitoneal route. Hyperglycemic rats were treated with EAAA 50,100mg/kg and Metformin 120 mg/kg body wt. Biological specifications such as glucose level in blood, insulin level in serum and glucose transporter (GLUT-2) protein expression were measured. In addition, histopathological study of pancreatic tissue was performed to check changes occurred in β-cell complex. Results: No mortality was observed during safety study. Weight of treated rats was found to be increased whereas glucose level in blood samples of EAAA treated rats were showed improvement as compare to control groups. The result shows up-regulation of serum insulin levels and small changes in the expression of GLUT-2 after 4-week treatment with the EAAA treatment. The presence of polyphenols in EAAA may have provoked ingestion of glucose by changing the glucose transporter. It has been identified by many researchers that herbal extracts which are rich in polyphenols are responsible for debilitating insulin resistance and thus restrain glucose uptake by expressing GLUT-2 in pancreatic cells of diabetic rats. Histological analysis demonstrated improvement in the structural decay of β-cells of pancreatic tissue. Conclusion: The results indicate the thinkable effect of EAAA in STZ-induced diabetic Rats.

Background::Oxidative stress is caused due to the overproduction of the reactive oxygen species (ROS) and the disturbance developed in the antioxidant potential of biochemical processes. ROS mostly form in the brain due to the high consumption of oxygen and the insufficiency of endogenous antioxidant resistance mechanisms. Cytochrome P450 2E1 has an excessive percentage of NADPH oxidase activity, which causes the production of ROS and increases oxidative stress.Objectives::We have studied the effect of ethyl acetate extract of Achyranthes Aspera (EAAA) on ROS in the brain of diabetes-induced rats. We have also investigated the possible molecular mechanism of reduction in ROS through molecular docking.Methods:To study the oxidative stress induced by ROS in diabetic rats, we estimated the ROS in rat brain through flow cytometry. The oral dose of EAAA 50mg/kg and 100 mg/kg was given to diabetesinduced rats. Results were articulated as mean ± standard deviation (SD). Data were analyzed using analysis of variance (ANOVA) followed by Bonferroni as a post hoc test. We performed molecular docking of flavonoids on CYP2E1 to study the inhibitory potential.Results::The results have shown that EAAA reduces the generation of ROS in the diabetes-induced rat in a dose-dependent manner. The oral dose of EAAA 50mg/kg and 100 mg/kg was given to the rats and the ROS generation got affected accordingly. Luteolin, quercetin, and apigenin inhibited the CYP2E1 very effectively. Luteolin formed 4 hydrogen bonds with CYP2E1, which indicated its potential inhibition. Although, luteolin and apigenin showed a very good binding affinity with the enzyme.Conclusion::From the present work, we have concluded that the ethyl acetate extract of achyrantesaspera can effectively inhibit the ROS generation in the diabetes-induced rats by inhibiting the activity of CYP2E1.

Diabetes is one of the most common disorders that substantially contributes to an increase in global health burden. As a metabolic disorder, diabetes is associated with various medical conditions and diseases such as obesity, hypertension, cardiovascular diseases, and atherosclerosis. In this review, we cover the scientific studies on sodium/glucose cotransporter (SGLT) inhibitors published during the last decade. Our focus on providing an exhaustive overview of SGLT inhibitors enabled us to present their chemical classification for the first time.

Background: Neuropathy can be induced in rats by peripheral injuries, depending on compression of complete or a section of sciatic nerve and chemically by Streptozotocin (STZ). Materials and Methods: In the present study neuropathic pain were induced in rats by two methods, chronic constriction injury (surgical model) and STZ (40mg/kg/i.p.) induced diabetes (drug induced model). In both the models, behavioural as well as markers of oxidative stress were studied. Behavioural parameters were tested using vonfrey hair and Randall Selitto analgesiometer whereas biochemical parameter includes glycosylated haemoglobin and markers of oxidative stress. The study was further supported by histopathology of sciatic nerve. Flavonoid rich extract of Allium cepa Lam. leaves was administered at three different doses viz. 25, 50 and 100mg/kg/p.o to the rats with neuropathic pain. Both the models of neuropathic pain showed significant alteration in behavioural as well as oxidative stress parameters. Results: Treatment of Allium cepa leaves extract showed dose dependent improvement in behavioural and biochemical parameters towards normal (p value <0.001, <0.05 and <0.01). The altered histopathological changes in sciatic nerve were also significantly improved as compared to rats with neuropathic pain. Conclusion: The neuroprotective effects of the Allium cepa leaves extract is a virtue of its strong antioxidant activity.

In recent years, the concept of synthesis of organic compounds follows green chemistry principle in order to minimize environmental hazards caused due to organic solvents. Thus to implement an environment-friendly approach, researchers stand in a need of water-compatible catalysts in order to establish a library compound of pharmacologically important moieties with distinct properties. Exceptional interest of researchers gained by the boric acid owing to its easy commercial availability, eco-friendly physicochemical properties. It is recently proven to be a good substitute for conventional acidic catalytic materials. Boric acid successfully catalysed various organic conversions useful in day-to-day chemistry lab such as addition, esterification, substitution and condensation type of reactions. Additionally, boric acid is also useful in numerous multicomponent reactions involved in the synthesis of various biologically important heterocycles.

Background: Flavonoids, a group of polyphenols responsible for protective role against many diseased conditions, provide antioxidant activity which is the reason for their medicinal properties. Tactile allodynia is a behavioral biomarker of neuropathy that is well estimated by von Frey filaments and Randall–Selitto test. Objective: Ficus carica Lam. leaves were studied for the conformation of flavonoids in ethyl acetate fraction of methanolic extract (FCEA) using GC-HRMS for the identification of flavonoids. It was analyzed for antioxidant activity by in vitro free radical scavenging activity, performed using 2,2-diphenyl-1-picrylhydrazyl (DPPH) followed by blood glucose-level estimation, evaluation of neuropathic pain, and kidney and liver function tests in diabetic rats. Materials and Methods: The shade-dried leaves of F. carica Lam. were extracted with methanol and after that fractionated using ethyl acetate (FCEA). The characterization of FCEA was established using GC-HRMS. In vitro free radical scavenging activity was performed using DPPH assay. Diabetes was induced using streptozotocin (40 mg/kg/intraperitoneally), and effects of FCEA were studied on blood glucose level, neuropathy markers, and liver and kidney functions of diabetic rats. Results: GC-HRMS results highlighted the presence of quercetin, kaempferol, and chrysin in FCEA with free radical scavenging activity of 78.35% and IC50 value of 5.508 μM. FCEA reduces glucose levels and also shows protective effects in case of diabetic neuropathy as it increases the threshold of withdrawal latency in tactile allodynia and also decreases the serum glutamic-oxaloacetic transaminase, serum glutamic-pyruvic transaminase, blood urea nitrogen, and creatinine levels. Conclusion: The protective effects of FCEA against diabetic neuropathy, hepatoprotective and nephroprotective effects might be due to strong antioxidant property of important flavonoids present which is confirmed in the study.

Canna indica L. (Cannaceae) roots and rhizomes were reported to possess various biological properties like antimicrobial, anthelmintic potential and HIV-1 reverse transcriptase inhibition. In our previous studies, they showed antidiabetic activity on normal rats and rats co-addicted with caffeine and nicotine. In the pursuit of the phytochemical/s responsible for these biological activities, present study was aimed at phytochemical evaluation of hydroalcoholic extract (HAE) of C. indica L. roots and rhizomes; including preliminary screening, thin layer chromatography, H1-NMR and HR-LC/MS-MS analysis. After preliminary detection of flavonoids, tannins and sterols, HAE was tested for presence of β-sitosterol using TLC. H1-NMR spectrum of HAE revealed the presence of around 761 deshielded protons corresponding to different polar compounds. HR-LC/MS-MS analysis carried out at both positive and negative ion mode, indicated the presence of more than 90 compounds including short fragment of peptide. As per METLIN database, predicted major phytochemicals were 3'-hydroxytrimethoprim, 3,7-epoxycaryophyllan-6-one, swietenine, typhasterol, hexacosanedioic acid and 3β, 6α,7α-trihydroxy-5β-cholan-24-oic acid few of which, are biologically active.

Objective: This study was designed to evaluate the protective effect of Canna indica L. extract against caffeine-nicotine administration-induced type 2 diabetes exaggeration in rats.Methods: A study was conducted for three weeks in four rat groups (n=6); viz. type 2 diabetic control group, a caffeine-nicotine diabetic control group (20mg/kg, 0.4mg/kg, ip twice daily), and Canna indica L. extract and caffeine-nicotine treatment group and standard drug treated caffeine-nicotine diabetic group (Glibencamide, 5mg/kg, once daily). Type 2 diabetes was induced by two weeks high fatty diet and a single dose streptozotocin (50mg/kg, ip) on 1th day of the study in all groups. Blood and urine samples were collected every week for serum biochemical analysis.Results: Results of extract treatment and standard drug treatment were compared with untreated caffeine-nicotine co-administration group. Difference in each relevant serum parameter was analyzed through ANOVA and Dunett’s t test. Extract treated caffeine-nicotine-diabetic group showed about 150-200mg/dL (p<0.001) reduction in the serum glucose than untreated caffeine-nicotine-diabetic control group. Extract treatment reduces serum glucose by 10-15 mg/dL than glibenclamide treatment with higher significance (p<0.001). Extract treatment showed better results than standard drug in liver and kidney function test and exhibited its better potential in controlling diabetic complications. Extract treatment increased HDL-C and reduced triglycerides, LDL-C, VLDL-C and TC much better and with higher significance than standard drug. Extract treatment reduced TC by at least 60-80mg/dL (p<0.01) in comparison to caffeine-nicotine-diabetic control group. Extract treatment reduced 10-15mg/dL of more total cholesterol than that of standard drug.Conclusion: Caffeine-nicotine co-administration-induced exaggeration of type 2 diabetes was better treated by CI extract than that of standard drug gibenclamide.

Flavonols aglycones are well established in plant extracts with omnipresence of common flavonols like kaempferol, quercetin and myricetin. Quercetin has been reported for various pharmacological activities with major ones in the field of inflammation, cancer, arthritis, diabetes and its complications. Leaves of plants selected for this study viz. Allium cepa L., Ficus carica L. and Ziziphus mauritiana L. reported to have antioxidant, anticancer, hypoglycemic activities. It is hypothetised thisactivities are due to flavonoids present in these plants. Hence the ethylacetate fraction of methanolic extract of these leaves was obtained as it provides flavanoid rich fraction and the samples were prepared and HPTLC analysis was performed against standard quercetin and their quantitative analysis was performed, the solvent system toluene: ethyl acetate: formic acid (9: 1: 0.5) was selected. It was observed that these plants shows presence of quercetin where A. cepa has highest concentration with F. carica and Z. mauritiana having quercetin in declining order. The calibration curve was linear in the range of 0.1 to 0.7 μg for quercetin. Further a correlation coefficient of 0.999 indicates good linearity between concentration and area. Thus, it was proved that the plants used in the study has presence of quercetin which is possibly the reason having the pharmacological uses.

Objective: Antioxidant potential has protective effects in diabetic neuropathy (DN); hence, the present study was designed with an objective to quantify quercetin from shade-dried leaves of Allium cepa Lam. and to study its effects on streptozotocin (STZ)-induced chronic DN. Materials and Methods: The shade-dried leaves of A. cepa Lam. were extracted with methanol and then fractionated using ethyl acetate (ACEA). The quantification of quercetin in ACEA was evaluated by high-performance thin layer chromatography (HPTLC). The STZ (40 mg/kg) was administered to Sprague-Dawley rats (180-250 g) maintained at normal housing conditions. The STZ was administered once a day for 3 consecutive days. The elevation in blood glucose was monitored for 3 weeks periodically using flavin adenine dinucleotide-glucose dehydrogenase method by Contour TS glucometer. Rats showing blood glucose above 250 mg/dl were selected for the study. Animals were divided into eight groups. ACEA (25, 50, and 100 mg/kg), quercetin (40 mg/kg), metformin (120 mg/kg), and gabapentin (100 mg/kg) were given orally once a day for 2 weeks. The blood glucose level was again measured at the end of treatment to assess DN. Thermal hyperalgesia, cold allodynia, motor incoordination, and neurotoxicity were studied initially and at the end of 2-week treatment. Biochemical parameters were also evaluated after 2-week drug treatment. Results: The quercetin present in ACEA was 4.82% by HPTLC. All the ACEA treatment reduces blood glucose level at the end of the 2-week study and shows a significant neuroprotective effect in STZ-induced DN in the above experimental models. Conclusion: The quercetin present in ACEA proved protective effect in STZ-induced DN.

Conclusion: The BH and CC extracts have elucidated peaks that were corresponding with standard peaks on undertaking chromatographic studies.

Objective: This study evaluated the toxic effect of simultaneously injected normal doses of caffeine and nicotine in diabetic lab animals. Methods: A study was conducted for three weeks in seven rat groups (n=6); viz. first non-diabetic group treated with caffeine (20 mg/kg, ip) twice daily, second with nicotine (0.4 mg/kg, ip) twice daily and third with both treatments simultaneously; whereas other three groups treated in the same way but inducing diabetes; and employing the seventh group as diabetic control. Type 2 diabetes was induced by high fatty diet prior for two weeks and a single streptozotocin injection on 1th day of study in all diabetic groups. Blood and urine samples were collected weekly to estimate blood parameters. Animals were sacrificed, and organs were collected for histopathology analysis. Results: Most blood parameters showed a rapid increase in diabetes in co-addiction group compared with their single addiction or non-addiction control groups. Caffeine-nicotine co-addiction group showed about 60-80 mg/dl (p<0.05) rise in serum glucose, 15-20 U/l in AST (p<0.01), 80-100 U/l in ALT (p<0.01), 20-30 mg/dl in Urea (p<0.01), 02 mg/dl in creatinine (p<0.05), 12-15 mg/dl (p<0.01) in LDL-C, 6-9 mg/dl in VLDL-C (p<0.01) and 60-90 mg/dl in TC levels (p<0.01) when compared with non-addicted diabetic control. There was a significant reduction in HDL-C (p<0.01) while the less significant rise in triglycerides in the case of co-addiction as compared to non-addiction diabetic control group. Histopathology results exhibited moderate to severe tissue damage in agreement with clinical biochemistry results. Conclusion: Nicotine-caffeine co-addiction harms exceptionally more in type 2 diabetes greater than their single addiction or non-addiction.

Background: Tribal groups in India and Bangladesh have been using water extract of Canna indica L. (CI) herb since long time to treat diabetes and its other complications. Objective: Present study was an evaluation of antidiabetic activity of polar compounds from CI rhizome and roots extract by oral administration in streptozotocin-induced type 1 diabetes in rats. Material and methods: Extract was prepared by macerating CI rhizome and roots using mixture of ethanol and water (1:1) and screened phytochemically. Research work was conducted for the period of three weeks on Sprague Dawley (SD) rat groups viz. extract treated normal control group, vehicle treated diabetic control group, and standard drug treated group; and extract treatment groups. Streptozotocin (STZ) (single dose 55 mg/kg, ip) was injected to induce type 1 diabetes, glibenclamide (GB) was given (5 mg/kg, po) once daily as standard drug and CI extract given (100 mg/kg, 200 mg/kg, po) once daily in two test groups. Blood samples were collected weekly and examined for hematological and biochemical parameters. Animals were sacrificed on 21 st day for histopathological study. Results: CI extract exhibited significant (p<0.05) hypoglycemic and hypolipidemic activity comparable to that of standard drug. When 200 mg/kg of extract was administered once daily for three weeks, it reduced 116 mg/dl of mean fasting blood glucose and about 2.5-3 ng/mL of serum insulin; and also elevated pancreatic islets density. Extract significantly elevated HDL cholesterol (20-22 mg/dl) and reduced LDL (25-30 mg/dl) and VLDL (8-10 mg/dl) cholesterol in treatment groups. Histopathological examination demonstrated protective effect of plant extract on pancreas, liver, and kidneys; exhibiting less diabetes-induced degenerative damage. Conclusion: Polar compounds from CI rhizome and roots were found effective in controlling type 1 diabetes and its cardiovascular, renal and hepatic complications.

Carissa congesta and Benincasa hispida are well-known medicinally important plants associated with diabetes, inflammation, protozal infections and cancer. Here, we emphasized up on the immunomodulatory potential of these plants as the source of lupeol, P-sitosterol and ursolic acid. Petroleum ether extracts of C. congesta roots and B. hispida seeds were subjected to acute toxicity studies. They were screened for its immunomodulatory prospective in rats by Haemagglutination Antibody (HA) titre and Delayed-Type Hypersensitivity (DTH) response using Sheep Red Blood Cells (SRBCs of-0.5x10⁹) as antigens. Carbon Clearance test (Phagocytic Index) was estimated by Indian ink suspension. Complete Freund's Adjuvant (CFA) induced arthritis model interpretation was done by paw edema, kene joint erosion (transverse section), body weights, arthritic index and biochemical levels (RBC, WBC and Hb levels). Both the extracts were found to be therapeutically safe up to 5000 mg/kg. Dosage of 100 mg/kg was not satisfactory; and 500 and 250 mg/kg showed significant immunostimmulation (HA Titre) and immunosuppression (DTH response, 48 h). Benincasa hispida seed and Carissa congesta root extracts showed phagocytic Index of 0.0163±0.003, 0.0145±0.003 and 0.0183±0.003, 0.0176±0.003 at 250 mg/kg and 500 mg/kg, respectively. CFA model revealed that the B. hispida seed and C. congesta root extracts decreased paw volume, knee joint erosion, increased body weights and biochemical parameters with an arthritic index of 1.31±0.12, 1.44±0.15 and 1. 16±0.09, 1.36±0.13 at 250 mg/kg and 500 mg, respectively. The results were interpreted by One- way ANOVA followed by Dunnett test. Extracts showed relevance as promising immunostimulators as compared to control.
