A series of salicylamide derivatives were designed, synthesized and evaluated as multifunctional agents for the treatment of Alzheimer's disease. In vitro assays demonstrated that most of the derivatives were selective AChE inhibitors. They showed good inhibitory activities of self- and Cu2+-induced Aβ1-42 aggregation, and significant antioxidant activities. Among them, compound 15b exhibited good
设计,合成和评估了一系列水杨酰胺衍生物,作为治疗阿尔茨海默氏病的多功能药物。体外测定表明,大多数衍生物是选择性的AChE抑制剂。他们表现出良好的自我和Cu2 +诱导的Aβ1-42聚集的抑制活性,以及显着的抗氧化活性。其中,化合物15b显示出对RatAChE和EeAChE的良好抑制活性,IC 50值分别为10.4μM和15.2μM。此外,15b表现出较高的抗氧化活性(2.46 Trolox当量),良好的自我和Cu2 +诱导的Aβ1-42聚集抑制能力(在25.0μM时分别为42.5%和31.4%)以及对自我和Cu2 +诱导的Aβ1的中等分解能力。 -42聚集原纤维(25μM时分别为23.4%和27.0%)。此外,图15b还显示了生物金属螯合能力,抗神经炎能力和BBB通透性。这些多功能特性表明,化合物15b值得选择用于进一步的药代动力学,毒性和行为研究,以测试其在AD治疗中的潜力。
