inhibitors. A further docking comparison between the 11a- and 12a-AChE complexes agreed with the different inhibitory potency observed in experiments. Besides, compounds 11f and 11l showed excellent ABTS radical-scavenging activities, with IC50 values of 9.07 ± 1.34 μM and 6.05 ± 1.17 μM, respectively, which were superior to the control, Trolox (IC50 = 11.03 ± 0.76 μM). It is worth noting that 3-aminoquinoline
设计合成了一系列新型含吗啉基的4 - N-苯基氨基喹啉衍生物,并对其抗胆碱酯酶活性和ABTS自由基清除活性进行了测试。其中,化合物11a、11g、11h、11j、11l和12a对AChE的抑制活性与参考加兰他敏相当。特别是,化合物11g对 AChE 和 BChE 显示出最有效的抑制作用,IC 50值分别为 1.94 ± 0.13 μM 和 28.37 ± 1.85 μM。动力学分析表明化合物11a和11g作为混合型 AChE 抑制剂。11a - 和12a -AChE 复合物之间的进一步对接比较与实验中观察到的不同抑制效力一致。此外,化合物11f和11l显示出优异的 ABTS 自由基清除活性,IC 50值分别为 9.07 ± 1.34 μM 和 6.05 ± 1.17 μM,优于对照 Trolox (IC 50 = 11.03 ± 0.76 μM)。值得注意的是,3-氨基喹啉衍生物12a –
