A series of novel ferulic acid-O-alkylamines derivatives were designed, synthesized, and evaluated as multitarget-directed ligands against Alzheimer's disease. In vitro studies displayed that all the synthesized target compounds showed impressive inhibitory activity against butyrylcholinesterase (BuChE), significant inhibition/disaggregation of self-induced β-amyloid (Aβ) aggregation and acted as potential
设计,合成和评估了一系列新颖的阿魏酸-O-烷基胺衍生物,作为针对阿尔茨海默氏病的多靶标定向配体。体外研究表明,所有合成的目标化合物均显示出对丁酰胆碱酯酶(BuChE)的出色抑制活性,对自诱导的β-淀粉样蛋白(Aβ)聚集具有显着的抑制/解聚作用,并充当了潜在的抗氧化剂。特别是,发现化合物7f是最有效的BuChE抑制剂之一(马血清BuChE的IC50值为0.021μM,ratBuChE的IC50值为8.63μM,人血清的BuChE的IC50值为0.07μM),是良好的乙酰胆碱酯酶(AChE)抑制剂(IC50 =电鳗AChE为2.13μM,ratAChE为1.8μM,人红细胞AChE为3.82μM),分子对接的结果为其选择性BuChE抑制活性提供了解释。化合物7f对自诱导的Aβ1-42聚集(50.8±0.82%)也具有显着的抑制作用,并且发现其使自诱导的Aβ1-42聚集(38.7±0.65%)分
