series of related tacrine hybrid analogues were synthesized and evaluated as cholinesterase (ChE) inhibitors. The in vitro ChE assay results revealed that 1 showed moderate dual acetylcholinesterase (AChE)/ butyrylcholinesterase (BChE) inhibitory activity, while the hybrid 12j proved to be the most potent dual inhibitor among the designed derivatives, being almost as active as tacrine. Molecular modeling
合成了海洋天然产物肺病菌素B(1)和一系列相关的他克林杂种类似物,并作为胆碱酯酶(ChE)抑制剂进行了评估。体外ChE分析结果显示1显示出中等的双重乙酰胆碱酯酶(AChE)/丁酰胆碱酯酶(BChE)抑制活性,而杂种12j被证明是所设计衍生物中最有效的双重抑制剂,其活性几乎与他克林一样。分子模型研究和动力学分析表明12j与AChE的催化活性位点和外围阴离子位点都相互作用。化合物1和12j也可以抑制自我诱导的和AChE诱导的Aβ聚集。此外,针对人肝癌细胞系(HepG2)的基于细胞的分析显示,与他克林和多奈哌齐相比,1和12j没有显示出明显的肝毒性。两者合计,本研究证实化合物1是潜在的抗阿尔茨海默氏病(AD)命中,并且12j可以作为抗AD药物开发的多功能先导化合物得到强调。
