Abstract
Comparison of the in vivo and in vitro effects of S-(2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl)thiuronium bromide (1), 2-(2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosylthio-1,3,4-thiadiazolin-5-thione (2), and 2-(2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosylthio)-1,3-benzoxazole (3), as well as the antidiabetics Daonil and insulin on glycosidase enzymes has been investigated. Compound 1 inhibited both alpha- and beta-glucosidases, but the inhibition was more potent with the beta-enzyme. Compound 2 was found to be a weaker inhibitor of these enzymes, while compound 3 showed a slight apparent activation.
