A series of novel 2-(4-(4-substituted piperazin-1-yl)benzylidene)-1H-indene-1,3(2H)-diones were designed, synthesized and appraised as multifunctional anti-Alzheimer agents. In vitro studies of compounds 27–38 showed that these compounds exhibit moderate to excellent AChE, BuChE and Aβ aggregation inhibitory activity. Notably, compounds 34 and 38 appeared as most active multifunctional agents in the
设计,合成和评价了一系列新型的2-(4-(4-取代的哌嗪-1-基)亚苄基)-1 H-茚-1,3(2 H)-二酮作为多功能抗阿尔茨海默病药物。化合物27 – 38的体外研究表明,这些化合物具有中等至极好的AChE,BuChE和Aβ聚集抑制活性。值得注意的是,化合物34和38在整个系列中是最具活性的多功能剂,并且对AChE表现出优异的抑制作用(IC 50 = 0.048μM:34 ; 0.036μM:38),Aβ聚集(最大抑制百分比为82.2%,IC 50 = 9.2) μM:34; 最大抑制百分比为80.9%,IC 50 = 10.11μM:38),并且在ORAC-FL分析中显示出显着的抗氧化潜能。两种化合物还成功减少了SH-SY5Y细胞中H 2 O 2诱导的氧化应激。令人着迷的是,化合物34和38在SH-SY5Y细胞中对H 2 O 2和Aβ诱导的毒性表现出了令人钦佩的神经保护作用。另
