A series of chalcone Mannich base derivatives were designed, synthesized and evaluated as multifunctional agents for the treatment of Alzheimer’s disease based on the multi-target directed ligands design strategy. In vitro assays demonstrated that most of the derivatives exerted potent selective inhibitory potency on AChE with good multifunctional properties. Among them, representative compound 7c
基于多靶点定向配体设计策略,设计,合成和评估了一系列查尔酮曼尼希碱衍生物,作为治疗阿尔茨海默氏病的多功能药物。体外试验表明,大多数衍生物对AChE都具有强大的选择性抑制作用,并具有良好的多功能性能。其中,代表性的化合物7c中显示出中度抑制效力为的Ee的AChE(IC 50 = 0.44μM)和MAO-B的抑制(IC 50 = 1.21μM),自诱导的良好的抑制作用β 1-42聚集(55.0%,在25μM时),生物金属螯合性能,适度的抗氧化活性,是Trolox的1.93倍。此外,对AChE抑制的动力学分析和分子模型研究均显示7c表现出混合型抑制,同时与AChE的CAS和PAS结合。另外,7c还显示出高的BBB渗透性。这些性质表明7c可能是用于治疗AD的有前途的多功能剂。
