diabetes. Xanthones were naturally occurring antioxidants, and they may also be potential AGIs. In this study, eleven 1,6- and 1,3-substituted xanthone compounds were designed and synthesized, of which four were new compounds. Their α-glucosidase inhibitory activities in vitro and in silico were evaluated. Five xanthone compounds with higher activity than acarbose were screened out, and the xanthones substituted
α-葡萄糖苷酶抑制剂(AGI)是临床上常用的治疗2型糖尿病的药物。氧杂蒽酮是天然存在的抗氧化剂,它们也可能是潜在的 AGI。本研究设计并合成了11种1,6-和1,3-取代的呫吨酮化合物,其中4种为新化合物。评估了它们的体外和计算机模拟的α-葡萄糖苷酶抑制活性。筛选出5种比阿卡波糖活性更高的呫吨酮化合物,其中1,6位取代的呫吨酮化合物更可能是潜在的α-葡萄糖苷酶非竞争性抑制剂。采用分子对接方法进一步研究了氧杂蒽酮与α-葡萄糖苷酶的结合方式,结果表明非竞争性抑制剂对α-葡萄糖苷酶1位点的抑制作用可能与带有氨基的化合物形成的氢键有关。酸残基 ASN165、HIS209、TRY207、ASP243 和 SER104。该研究为α-葡萄糖苷酶非竞争性呫吨酮抑制剂的快速发现和结构修饰提供了理论基础。
