respectively) and MAO-B (IC50 = 20.1 ± 0.16 μM and 43.8 ± 2.0% at 10 μM, respectively) inhibitory activities, moderate self-induced Aβ1–42 aggregation inhibitory potency (35.4 ± 0.42% and 48.0 ± 1.53% at 25 μM, respectively) and potential antioxidant activity. In addition, the two representative compounds displayed high BBB permeability in vitro. Taken together, these multifunctional properties make 11b and
设计,合成和评估了一系列5,6-二甲氧基苯并[ d ]异噻唑-3(2 H)-N-烷基苄胺衍生物,作为治疗阿尔茨海默氏病(AD)的潜在多功能剂。在体外测定法表明,大部分这些衍生物的有选择性的AChE抑制剂具有良好的多功能性质。其中,化合物11b和11d具有综合优势,具有良好的AChE(IC 50 = 0.29±0.01μM和0.46±0.02μM),MAO-A(IC 50 = 8.2±0.08μM和7.9±0.07μM)和MAO-B(IC 50 分别为20.1±0.16μM和10μM时的43.8±2.0%)抑制活性,中度自我诱导的Aβ1–42聚集抑制能力(25μM时分别为35.4±0.42%和48.0±1.53%)和潜在的抗氧化活性。另外,这两种代表性化合物在体外显示出高的BBB渗透性。综上所述,这些多功能特性使11b和11d成为开发抗AD高效药物的有希望的候选者。
