Selective α-glucosidase substrates and inhibitors containing short aromatic peptidyl moieties
摘要:
We constructed a library of sugar-dipeptide conjugate to find out the best complementary against hydrophobic pocket of alpha-glucosidase. The best substrate showed 150-fold improved K-m value relative p-acetaminophenyl-alpha-D-glucopyranoside for alpha-glucosidase from Bacillus stearothermophillus. Using information from the complementary, we synthesized sp-WY and beta-Glc-sp-WY, which selectivity inhibited the cognate enzyme. (C) 2011 Elsevier Ltd. All rights reserved.
A method of producing a phenol derivative glycoside is provided. The method comprises the step of allowing a saccharide and a phenol derivative to react with each other in the presence of an enzyme to produce the phenol derivative glycoside. The enzyme is selected from the group consisting of neopullulanase, cyclomaltodextrinase, maltogenic &agr;-amylase, and saccharifying amylase having cyclodextrin synthesizing capability.
