Further, their inhibitory activity against α-glucosidase enzyme was investigated. Among various synthesized 2-(pyridin-2-yl)H-imidazo[1,2-a]pyridines, compound 5 g exhibited the best inhibitory potency having IC50 value of 3.7 μM which was 18 times more potent than acarbose as standard inhibitor (IC50 = 67.4 μM). The antioxidant activity of these compounds was evaluated by using in vitro 2-azinobis-3-
设计并通过Suzuki 偶联和缩合反应分两步合成了一系列新型 2-(pyridin-2-yl) H-咪唑并[1,2 - a ]吡啶衍生物,具有广泛的底物范围和良好的收率。使用不同的光谱技术表征合成化合物的结构。此外,研究了它们对α-葡萄糖苷酶的抑制活性。在各种合成的 2-(pyridin-2-yl) H - imidazo[1,2 - a ]pyridines 中,化合物5 g表现出最好的抑制效力,IC 50值为 3.7 μM,是标准抑制剂阿卡波糖的 18 倍(集成电路50 = 67.4 微米)。这些化合物的抗氧化活性通过使用体外2-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) 和 2,2-diphenyl-1-picrylhydrazyl (DPPH) 自由基生物测定来评估。进行分子对接以建立与靶酶的相互作用,这也证实了体
