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.
