Studies on the a-glucoside hydrolase inhibitor, adiposin IV. Effect of adiposin on intestinal digestion of carbohydrates in experimental animals

Abstract

Adiposins showed a potent inhibitory activity against a-glucoside hydrolases such as salivary and pancreatic a-amylases, and intestinal disaccharidases in vivo. They suppressed the increase of the blood glucose level and the secretion of insulin in mice and rats which both had been fasted and then forced-fed on cooked corn starch, sucrose or maltose. The suppression of the increase in the body weight gains, and of the secretion of insulin and triglyceride in blood were observed in the experimental animals which were given diet containing adiposins. Hematological and histopathological examinations of animals treated with adiposins did not reveal any remarkable changes after a 3 months toxicity test. Adiposins did not show any intravenous acute toxicity in mice at dose levels (p.o.) less than 10 g/kg of body weight. © 1982, JAPAN ANTIBIOTICS RESEARCH ASSOCIATION. All rights reserved.
