A new series of 1,2,4-triazine derivatives bearing carbazole moiety 7a-7p were designed, synthesized, and evaluated for their α-glucosidase inhibitory activity. The majority of the screened compounds displayed potent α-glucosidase inhibitory activity, with IC50 values in the range of 4.27±0.07-47.75±0.25μM as compared to the standard drug acarbose. Among the series, compound 7k represented the most
设计,合成了一系列新的带有咔唑部分7a-7p的1,2,4-三嗪衍生物,并评估了其对α-葡萄糖苷酶的抑制活性。与标准药物阿卡波糖相比,大多数被筛选的化合物显示出有效的α-葡萄糖苷酶抑制活性,IC50值在4.27±0.07-47.75±0.25μM范围内。在该系列中,化合物7k表现出最强的α-葡萄糖苷酶抑制活性,IC50值为4.27±0.07μM。动力学分析表明,化合物7k是一种非竞争性抑制剂,Ki为4.43μM。此外,通过分子对接证实了化合物7k与α-葡糖苷酶的结合相互作用。这项研究表明,这些带有咔唑部分的1,2,4-三嗪衍生物是一类新型的α-葡萄糖苷酶抑制剂。
