In this study, a series of multifunctional hybrids against Alzheimer’s disease were designed and obtained by conjugating the pharmacophores of xanthone and alkylbenzylamine through the alkyl linker. Biological activity results demonstrated that compound 4j was the most potent and balanced dual ChEs inhibitor with IC50 values 0.85 μM and 0.59 μM for eeAChE and eqBuChE, respectively. Kinetic analysis
在这项研究中,设计了一系列针对阿尔茨海默氏病的多功能杂种,方法是通过烷基连接体缀合蒽酮和烷基苄胺的药效基团。生物活性结果表明,化合物4j是最有效和平衡的双重ChEs抑制剂,eeAChE和eqBuChE的IC 50值分别为0.85μM和0.59μM。动力学分析和对接研究表明,化合物4j是AChE和BuChE的混合型抑制剂。此外,它还具有很好的渗透BBB,清除自由基(4.6 trolox当量)以及与Cu 2+和Al 3+选择性螯合的能力。配体/金属摩尔比为1:1.4。重要的是,在评估细胞毒性和急性毒性后,我们发现化合物4j可以改善东amine碱诱导的失忆症小鼠的记忆功能。因此,化合物4j可被认为是有前途的先导化合物,用于AD治疗中的进一步研究。
