  Synthesis and α-amylase inhibitory activity of glucose–deoxynojirimycin conjugates

  摘要：

  Inhibitors of alpha-amylase have attracted attention for their putative effects against diabetes mellitus. Although numerous studies have explored natural small molecule inhibitors, acarbose is currently the only compound with sufficient inhibitory potency and drug-like characteristics to be considered as a potential therapeutic agent. We have synthesized conjugates of the potent glucosidase inhibitor, 1-deoxynojirimycin, and glucose, with the aim of enhancing inhibitory activity against alpha-amylase. This synthetic conjugate showed increased inhibition of alpha-amylase compared to 1-deoxynojirimycin alone, suggesting that similar modifications of existing glucosidase inhibitors may yield more potent alpha-amylase inhibitors.
