Abstract Background Tetracarpidium conophorum is one of the numerous folklore medicinal plants for managing diabetes but mode action and bioactive compounds responsible antihyperglycemic property are missing in literatures. This study aimed at investigating possible modes its using both in-vitro ex-vivo methods. Powdered seed (TECOSE) was extracted with methanol standard extraction procedure. G...

A recombinant Bacillus subtilis strain (ATCC 31784) haboring the plasmid pC194 with a thermostable alpha-amylase gene was cultured in a 22-l B. Braun Biostat C fermenter. Traditional batch operations suffer from low cell mass and protein productions because a high initial glucose concentration causes substrate inhibition and also product inhibition due to acetate accumulation. An exponential fe...

1. The comparative effects of raw soya beans on food intake, growth, digestive organ weight, and enzyme activities in goslings and chicks were studied, 2. Goslings were more affected than chicks by the ingestion of a raw soya-bean diet (RSD) in the following ways: reduction in food intake and growth rate; increase in relative weight of the digestive organs; reduction in specific activities of l...

The therapeutic potential of leaf extract of Bryophyllum pinnatum was screened for in vitro antioxidant potential and alpha amylase inhibitory action. Antioxidant activity of the extract was evaluated for hydroxyl radical scavenging activity by Fenton reaction, free radical scavenging by hydrogen peroxide scavenging and superoxide scavenging potential. The in vitro alpha amylase inhibition acti...

We have previously shown that dietary glucose can reduce amylase activity in both adults and larvae of Drosophila; this reduction in enzyme activity reflects a reduction in the quantity of amylase protein, rather than an inhibition of enzyme activity. Here, we report that we have now defined conditions in which the repressive effect of glucose can be greater than 100-fold. Moreover, this repres...

Midgut hydrolytic enzymes of Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) were identified and partially characterized. Km, Vmax, optimum pH, and specific activity were determined for proteolytic enzymes and αamylases. All hydrolytic enzyme activity had an optimum pH value in the alkaline pH range. We observed major serine protease activity, together with minor cysteine-like activity, th...

An in vitro antidiabetic activity on α -amylase and α -glucosidase activity of novel 10-chloro-4-(2-chlorophenyl)-12-phenyl-5,6-dihydropyrimido[4,5-a]acridin-2-amines (3a-3f) were evaluated. Structures of the synthesized molecules were studied by FT-IR, (1)H NMR, (13)C NMR, EI-MS, and single crystal X-ray structural analysis data. An in silico molecular docking was performed on synthesized mole...

This study was designed to investigate the inhibitory effect of Gynura procumbens extract against carbohydrate digesting enzymes and its ability to ameliorate postprandial hyperglycemia in streptozotocin (STZ)-induced diabetic mice. G. procumbens extract showed prominent α-glucosidase and α-amylase inhibitory effects. The half-maximal inhibitory concentration (IC50) of G. procumbens extract aga...

Using homogenates of autopsy tissue, we compared three widely available techniques for separating amylase isoenzymes: wheat-germ inhibition (WI), and electrophoresis on cellulose acetate (CA) or agarose (AG). WI separated amylase into two isoforms, CA into seven (three pancreatic and four salivary), and AG into nine (five pancreatic and four salivary). CA and WI had similar isoamylase detection...

Diabetes mellitus type 2 is a metabolic disorder characterized by hyperglycemia including insulin resistance and relative lack of insulin. Type 2 diabetes is expected to reduce ten-year-shorter life expectancy. In this research article, we have isolated two terpenoids from the stem bark of Syzygium alternifoliumby column chromatography.The isolated compounds were identified as friedelin and 3β-...
