In an endeavor to find a novel series of antihyperglycemic agents, new benzimidazole and pyrimidine derivatives were successfully synthesized efficiently in high yield with high purity, starting from amino acids in the presence of phosphorus oxychloride (POCl3). The synthesized compounds were identified by 1H-NMR, 13C-NMR, FT-IR spectroscopic techniques and elemental analysis. All products were...

Inhibitory effects of root endophytic actinomycete A-12 from Azadirachta indica A. Juss (Indian lilac, neem) against α-amylase and α-glucosidase were studied. The antioxidant capability was assessed through 2,2-diphenyl-picrylhydrazyl (DPPH), hydroxy radical scavenging and reducing power assays. In vitro antidiabetic activity of ethyl acetate extract revealed good inhibition exhibiting IC50 val...

BACKGROUND Mangifera mekongensis (Anacardiaceae) is cultivated for its edible fruit and has been used in traditional Vietnamese medicine for its anti-aging properties and for treating diabetes, vermifuge, and dysentery. As part of a search for biologically active compounds with reduction of the rate of glucose absorption, a screening has been initiated to evaluate natural product extracts for t...

A soil microorganism producing αand β-glucosidase inhibitors was identified as Bacillus lentimorbus, based on the fatty acid and morphological analyses, along with biochemical and physiological tests. The α-glucosidase inhibitor was highly produced by this strain in a culture medium containing 0.25% of sodium glutamate and 0.5% of glucose, pH 8.0 at 30C for 2 days. The α-glucosidase inhibitor f...

A novel series of 2-substituted-4,6-diarylpyrimidines 6a-6t has been synthesized, characterized by ¹H-NMR, 13C-NMR and HRMS, and screened for in vitro α-glucosidase inhibitory activity. The majority of the screened compounds possessed significant α-glucosidase inhibitory activity with IC50 values ranging from 19.6 ± 0.21 to 38.9 ± 0.35 μM, which is more potent than the positive control α-glucos...

This study was designed to investigate the inhibitory effects of Polyopes lancifolia extract (PLE) on α-glucosidase activity, α-amylase activitiy, and postprandial hyperglycemia in streptozotocin (STZ)-induced diabetic mice. The results of this study revealed a marked inhibitory effect of PLE on α-glucosidase and α-amylase activities. The IC50s of PLE against α-glucosidase and α-amylase were 0....

Diabetes mellitus is a metabolic disorder and the management is an important criterion for pharmacotherapy. The medicinal plants play very important role in preventing the progress of the disease. Present study deals with screening of polyherbal extracts using in-vitro techniques for its antidiabetic activity. The plants used in the study are Eugenia jambolana and Cinnamomum zeylenicum. The pol...

Hemi-pyocyanin (HPC) is a heterocyclic nitrogenous compound with some reported potential medical effects. The current report aimed to investigate the use of organic industrial waste for production HPC via microbial fermentation. novel antidiabetic activity was also accessed and in this work. A peanut oil processing by-product (groundnut cake) screened as best substrate Pseudomonas aeruginosa TU...

Diabetes mellitus is a metabolic disorder of glucose metabolism which correlates with postprandial hyperglycemia and oxidative stress. Control of blood glucose level is imperative in the management of diabetes. The present study tested the hypothesis that Costus afer, an antihyperglycemic medicinal plant, possesses inhibitory activity against carbohydrate hydrolyzing enzymes. Hexane, ethyl acet...
