A novel series of 2,4,5-triarylimidazole-1,2,3-triazole derivatives were synthesized via copper(I)-catalyzed azide-alkyne click chemistry, and evaluated for their α-glucosidase inhibitory activity. All tested compounds showed potent α-glucosidase inhibitory activity with IC50 ranging from 15.16±0.18 to 48.15±0.37μM, in comparison to the standard drug, acarbose (IC50=817.38±6.27μM). Among all the tested
通过铜(I)催化的叠氮化物-炔炔点击化学合成了一系列新的2,4,5-三芳基咪唑-1,2,3-三唑衍生物,并对其α-葡萄糖苷酶抑制活性进行了评估。与标准药物阿卡波糖(IC50 = 817.38±6.27μM)相比,所有测试化合物均显示出有效的α-葡萄糖苷酶抑制活性,IC50为15.16±0.18至48.15±0.37μM。在所有测试的化合物中,发现5j是最具活性的化合物,IC50值为15.16±0.18μM,并且表现为非竞争性抑制剂,Ki为14.78μM。另外,进行了分子对接研究以探索这些化合物与α-葡萄糖苷酶的结合相互作用。
