on chalcone derivatives as AChE inhibitors, a series of ferulic acid (FA) tertiary amine derivatives similar to chalcone compounds were designed and synthesized. The results of bioactivity evaluation revealed that most of new synthesized compounds had comparable or more potent AChE inhibitory activity than the control drug Rivastigmine. The alteration of carbon chain linking tertiary amine groups and
基于我们最近对查尔酮衍生物作为AChE抑制剂的研究,设计并合成了一系列类似于查尔酮化合物的阿魏酸(FA)叔胺衍生物。生物活性评估的结果表明,大多数新合成的化合物具有比对照药物Rivastigmine相当或更强的AChE抑制活性。碳链连接的叔胺基团和阿魏酸支架的变化显着影响了对AChE的抑制活性。其中化合物6d(IC 50:0.71±0.09μmol/ L)和6e(IC 50:1.11±0.17μmol/ L)的抑制活性分别是Rivastigmine对AChE(IC的抑制作用)的15倍和9倍。50:10.54±0.86μmol/ L)。此外,化合物6d对AChE的选择性比对丁酰胆碱酯酶(BuChE)最高(比率:18.3)。动力学研究表明化合物6d显示出对AChE的混合型抑制作用。分子对接的结果表明,化合物6d在酶结构域中分别与具有三个氨基酸位点(Trp84,Tyr334和Trp279)的AC
