of phthalide alkyl tertiary amine derivatives were designed, synthesized and evaluated as potential multi-target agents against Alzheimer’s disease (AD). The results indicated that almost all the compounds displayed significant AChE inhibitory and selective activities. Besides, most of the derivatives exhibited increased self-induced Aβ1-42 aggregation inhibitory activity compared to the lead compound
设计,合成和评估了一系列邻苯二甲酰基烷基叔胺衍生物,作为对抗阿尔茨海默氏病(AD)的潜在多靶标药物。结果表明,几乎所有化合物均显示出显着的AChE抑制和选择性活性。此外,大多数的衍生物显示出增加的自感甲β 1-42相比,铅化合物聚集抑制活性DL -NBP,有些化合物也发挥良好的抗氧化活性。具体而言,化合物I-8对AChE的抑制力最高(IC 50 = 2.66 nM),明显优于多奈哌齐(IC 50 = 26.4 nM)。此外,分子对接研究表明I-8可以与AChE的催化活性位点和外围阴离子位点结合。此外,化合物I-8在体外显示出优异的BBB渗透性。重要的是,逐步降低的被动回避测试表明,I-8可显着逆转东amine碱诱导的小鼠记忆缺陷。总的来说,这些结果表明I-8可能是用于进一步抗AD药物开发的有效且选择性的AChE抑制剂。
