A novel series of graveolinine derivatives were synthesized and evaluated as potential anti-Alzheimer agents. Compound 5f exhibited the best inhibitory activity for acetylcholinesterase (AChE) and had surprisingly potent inhibitory activity for butyrylcholinesterase (BuChE), with IC50 values of 0.72 μM and 0.16 μM, respectively. The results from Lineweaver-Burk plot and molecular modeling study indicated
合成了一系列新型的gravolinine衍生物,并将其评估为潜在的抗阿尔茨海默病药物。化合物5f对乙酰胆碱酯酶(AChE)表现出最好的抑制活性,并且对丁酰胆碱酯酶(BuChE)表现出令人惊讶的有效抑制活性,IC50值分别为0.72μM和0.16μM。Lineweaver-Burk图和分子建模研究的结果表明,化合物5f对AChE的非竞争性抑制作用。另外,这些衍生物显示出有效的自我诱导的β-淀粉样蛋白(Aβ)聚集抑制作用。此外,在50μM下5f对PC12和HepG2细胞没有明显的毒性。最后,体内研究证实5f可以显着改善东pol碱治疗的ICR小鼠的认知能力。所以,
