A series of scutellarein-O-acetamidoalkylbenzylamines derivatives were designed based on a multitarget-directed ligands strategy for the treatment of Alzheimer's disease. Among these compounds, compound T-22 demonstrated excellent acetylcholinesterase inhibitory, moderate inhibitory effects on self-induced Aβ1-42 aggregation, Cu2+-induced Aβ1-42 aggregation, human AChE-induced Aβ1-40 aggregation and
基于多靶标指导的配体策略设计了一系列的黄cut素-O-乙酰氨基烷基苄胺衍生物,用于治疗阿尔茨海默氏病。在这些化合物中,化合物T-22表现出优异的乙酰胆碱酯酶抑制作用,对自身诱导的Aβ1-42聚集,Cu2 +诱导的Aβ1-42聚集,人AChE诱导的Aβ1-40聚集和分解的Cu2 +诱导的孔聚集具有中等抑制作用。结构的Aβ1-42原纤维,还可以作为潜在的抗氧化剂和生物金属螯合剂。AChE抑制的动力学分析和分子建模研究均表明T-22与AChE的催化活性位点和外围阴离子位点都相互作用。而且,化合物T-22对H 2 O 2诱导的PC12细胞损伤显示出良好的神经保护作用,并且在SH-SY5Y细胞中毒性低。此外,逐步降低的被动回避测试表明,T-22可以显着逆转东pol碱诱导的小鼠记忆缺陷。两者合计,数据表明T-22是有趣的多功能铅化合物,值得AD进一步研究。
