Abstract

A novel series of biscoumarin-1,2,3-triazole hybrids 6a-n was prepared and evaluated for α-glucosidase inhibitory potential. All fourteen derivatives exhibited excellent α-glucosidase inhibitory activity with IC values ranging between 13.0 ± 1.5 and 75.5 ± 7.0 µM when compared with the acarbose as standard inhibitor (IC = 750.0 ± 12.0 µM). Among the synthesized compounds, compounds 6c (IC = 13.0 ± 1.5 µM) and 6g (IC = 16.4 ± 1.7 µM) exhibited the highest inhibitory activity against α-glucosidase and were non-cytotoxic towards normal fibroblast cells. Kinetic study revealed that compound 6c inhibits the α-glucosidase in a competitive mode. Furthermore, molecular docking investigation was performed to find interaction modes of the biscoumarin-1,2,3-triazole derivatives.

摘要

我们合成了一系列新型的二苯并吡喃-1,2,3-三唑杂合体 6a-n,并评估了它们对α-葡萄糖苷酶抑制潜力。与阿卡波糖(标准抑制剂,IC50=750.0 ± 12.0 μM)相比,这 14 种衍生物均表现出优异的α-葡萄糖苷酶抑制活性,IC50 值在 13.0 ± 1.5 和 75.5 ± 7.0 μM 之间。在所合成的化合物中,化合物 6c(IC50=13.0 ± 1.5 μM)和 6g(IC50=16.4 ± 1.7 μM)对α-葡萄糖苷酶表现出最高的抑制活性,且对正常成纤维细胞无细胞毒性。动力学研究表明,化合物 6c 以竞争性模式抑制α-葡萄糖苷酶。此外,还进行了分子对接研究,以找到二苯并吡喃-1,2,3-三唑衍生物的相互作用模式。
