개요Acarbose, a complex oligosaccharide isolated from Actinoplanes, is reportedly useful as an adjuvant therapy in diabetes. By inhibiting alpha-glucosidase, acarbose delays carbohydrate metabolism in the gastrointestinal tract and modulates changes in food induced blood sugar levels.

용도Acarbose is pseudo-oligosaccharide with a terminal C7-cyclitol patented in 1975 by Bayer. Acarbose is a component of the amylostatin complex produced by a species of Actinoplanes and Streptomyces. Acarbose acts as a potent inhibitor of alpha-glucosidases and saccharases. Since 1990, acarbose has been used therapeutically for the treatment of type 2 diabetes.

일반 설명Acarbose is a naturally occurring oligosaccharide,which is obtained from the microorganism Actinoplanes utahensis. It is a white to off-white powder that is soluble in water and has a pKa of 5.1. As one mightexpect, its affinity for α-glucosidase is based on it being apolysaccharide that the enzyme attempts to hydrolyze. Thisallows acarbose to act as a competitive inhibitor, which inturn reduces the intestinal absorption of starch, dextrin, anddissacharides.It is sold as 25-, 50-, and 100-mg tablets (Precose,generics) dosed with the first bite of each meal, up to t.i.d. Acarbose potently inhibits the glucoamylase activity of MGAM α-glucosidases and the sucrase activity of α-glucosidases, where as isomaltase activity is at most moderately inhibited at concentrations in the range of those in theintestinal lumen upon oral dosing, and trehalase and lactaseare not significantly inhibited. Some inhibition of pancreaticα-amylases may also contribute to the clinical effects.https://www.sciencedirect.com
