Background: A series of ferulic acid-donepezil hybrids were designed, synthesized and
evaluated as multifunctional agents for Alzheimer’s disease (AD) in vitro.
Methods: Among the synthesized compounds, compound TM-I-3 acted as an antioxidant (1.1eq of
Trolox), showed the highest BuChE inhibitory activity with IC50 value of 3.4 ± 0.21 μM, the result
of molecular provided a possible mechanism for its unexpected inhibitory activity against BuChE.
In addition, compound TM-I-3 inhibited and disaggregated self-induced Aβ1-42 aggregation by
61.1±1.8% and 53.1 ±3.4% at 25μM respectively, which was consistent with the transmission electron
microscopy (TEM) and molecular modeling study. Moreover, TM-I-3 exhibited a good protective
effect against H2O2-induced PC12 cell injury, with low toxicity in PC12 cells. Furthermore, our
investigation proved that TM-I-3 could penetrate the blood-brain barrier (BBB) in vitro, and abided
by the Lipinski’s rule of five.
Results and Conclusion: These data suggest that compound TM-I-3, an interesting multi-targeted
active molecule, offers an attractive starting point for further lead optimization in the drugdiscovery
development against the advanced stages of AD.
背景:设计、合成并评估了一系列阿魏酸-多奈哌齐杂化物,作为阿尔茨海默病(AD)的体外多功能药物。方法:在合成的化合物中,化合物TM-I-3具有抗氧化剂(1.1当量的Trolox)的作用,表现出最高的BuChE抑制活性,IC50值为3.4±0.21μM,其结果为分子提供了对BuChE具有意外抑制活性的可能机制。此外,化合物TM-I-3在25μM时分别抑制和分解了自诱导的Aβ1-42聚集,抑制率分别为61.1±1.8%和53.1±3.4%,这与透射电子显微镜(TEM)和分子建模研究的结果一致。此外,TM-I-3对H2O2诱导的PC12细胞损伤表现出良好的保护作用,对PC12细胞毒性低。此外,我们的研究证明,TM-I-3可以在体外穿透血脑屏障(BBB),并符合Lipinski的五项规则。结果和结论:这些数据表明,化合物TM-I-3是一种有趣的多靶点活性分子,为针对AD晚期药物研发的进一步先导药物优化提供了有吸引力的起点。
