A series of salicyladimine derivatives were designed, synthesized and evaluated as multi-target-directed ligands for the treatment of Alzheimer’s disease (AD). Biological activity results demonstrated that some derivatives possessed significant inhibitory activities against amyloid-β (Aβ) aggregation and human monoamine oxidase B (hMAO-B) as well as remarkable antioxidant effects and low cell toxicity
设计,合成和评估了一系列水杨二胺衍生物,作为多靶标定向配体用于治疗阿尔茨海默氏病(AD)。生物活性的结果表明,一些具有衍生物对淀粉状蛋白显著抑制活性β(A β)聚集和人类单胺氧化酶B(ħ MAO-B),以及显着的抗氧化作用和低毒性细胞。最佳化合物,5,表现出对抑制的自感应的优良效能β 1-42的聚合(91.3±2.1%,25μM),抑制ħ MAO-B(IC 50,1.73±0.39μM),抗氧化作用( IC 50为43.4±2.6μM用DPPH方法测得,在ABTS方法中等效为0.67±0.06 trolox当量),金属螯合和BBB渗透。此外,化合物5对ROS产生,H 2 O 2诱导的细胞凋亡,6-OHDA诱导的细胞损伤具有神经保护作用,并且具有显着的体外抗炎活性。总的来说,这些发现强调了化合物5是用于开发抗AD药物的潜在的平衡多功能神经保护剂。
