A new series of quinoxaline-hydrazidehydrazone-1,2,3-triazole hybrids, 14a–j, 15a–j and 16a–e, was designed, synthesized and screened for in vitro α-glucosidase and antioxidant activities. For the synthesis of the target compounds, quinoxaline hydrazides were condensed with benzaldehyde triazoles in the presence of AcOH (cat) in ethanol. The key step in the preparation of compounds 8a–j was the Cu(I)-catalyzed
设计,合成并筛选了一系列新的喹喔啉-酰肼-1,2,3-三唑杂种14a–j,15a–j和16a–e,用于体外α-葡萄糖苷酶和抗氧化活性。为了合成目标化合物,在乙醇中存在AcOH(催化剂)的情况下,将喹喔啉酰肼与苯甲醛三唑缩合。在化合物的制备中的关键步骤8A-J是铜(我)催化的[3 + 2]环加成反应加成(CuAAC)与适当的炔烃(6,7)和叠氮化物,和图13A-J由与最终步骤相同的点击反应,由简单的醛制备而成。通过邻苯二胺和丙酮酸经三步反应,包括环化,烷基化和酰化反应,合成喹喔啉酰肼(3,3a)。在这些杂种中,14a(IC 50 = 21.92μgmL -1),14b(IC 50 = 22.32μgmL -1),14c(IC 50 = 23.58μgmL -1)和15a(IC 50 = 24.50μgmL -1))与标准阿卡波糖(IC 50 = 22.32μgmL -1)相比,显示出良好的α
