Synthesis of N-(β-d-glucopyranosyl) monoamides of dicarboxylic acids as potential inhibitors of glycogen phosphorylase
摘要:
O-Peracetylated N-(beta-D-glucopyranosyl)imino trimethylphosphorane obtained in situ from 2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl azide and PMe3 was reacted with saturated and unsaturated aliphatic and aromatic dicarboxylic acids, or their anhydrides. or monoesters to give the corresponding N-(beta-D-glucopyranosyl) monoamides of dicarboxylic acids or derivatives. The acetyl protecting groups were removed according to the Zemplen protocol to give a series of compounds which showed moderate inhibitory effects against rabbit muscle glycogen phosphorylase b. The best inhibitor was 3-(N-beta-D-glucopyranosyl-carbamoy)propanoic acid (7) with K-i = 20 mu M. (c) 2006 Elsevier Ltd. All rights reserved.
