A series of 2-(3-hydroxybenzyl)benzo[d]isothiazol-3(2H)-one Mannich base derivatives were designed as potential multifunctional agents against Alzheimer’s disease. The twelve derivatives were synthesized and evaluated with various biological activities. In vitro, biological assays showed that most of the target compounds are selective AChE inhibitors and good antioxidants. Among them, compounds 6d
设计了一系列2-(3-羟基苄基)苯并[ d ]异噻唑-3(2H)-一个曼尼希碱衍生物作为对抗阿尔茨海默氏病的潜在多功能剂。合成了十二种衍生物,并用各种生物活性对其进行了评估。在体外,生物学分析表明,大多数目标化合物是选择性的AChE抑制剂和良好的抗氧化剂。其中化合物6d和13D是显示出显著选择性的AChE抑制代表剂(IC 50 = 1.09μM和2.01μM,分别地),有效的抗氧化剂活性,自诱导A的中等抑制β 1-42聚集,选择性金属螯合活性与Fe 2+和Cu 2+,对H 2 O 2诱导的PC12细胞损伤具有优异的神经保护作用,并具有良好的血脑屏障通透性。此外,逐步降低被动回避测试表明6d和13d可以改善东pol碱引起的小鼠认知功能障碍。以上结果表明,可以将化合物6d和13d设想为用于进一步开发抗AD药物的多功能先导化合物。
