A novel family of donepezil–ferulic acid hybrids were designed, synthesized and biologically evaluated as multi-target-directed ligands against Alzheimer's disease by fusing a fragment of donepezil and ferulic acid. The in vitro assay indicated that some of these molecules exhibited potent cholinesterase inhibitory activities, outstanding radical scavenging activities and good neuroprotective effects
通过将多奈哌齐和阿魏酸的片段融合,设计,合成了一个新的多奈哌齐-阿魏酸杂种家族,作为针对阿尔茨海默氏病的多靶标配体进行生物学评估。在体外测定法表明,一些这些分子的有力的显示胆碱酯酶抑制活性,杰出的自由基清除活性和良好的神经保护作用对PC12细胞,并能渗透到中枢神经系统。化合物5c特别显示出中等的乙酰胆碱酯酶抑制活性(电鳗乙酰胆碱酯酶的IC 50值为0.398μM)和丁酰胆碱酯酶的抑制活性(IC 50对于马血清丁酰胆碱酯酶为0.976μM)。它还显示出显着的抗氧化活性(ABTS方法为1.78 trolox当量,DPPH方法为IC 50值为24.9μM)。动力学研究和分子对接表明化合物5c与乙酰胆碱酯酶的外围阴离子位点和催化结合位点都相互作用。总体而言,这些结果表明,化合物5c是具有前景的药物,具有治疗阿尔茨海默氏病的平衡特性。
