This paper deals with molecular modeling of new therapeutic agents for treating the Alzheimer's disease. The therapeutic line adopted for this study is the cholinergic hypothesis. To modulate positively the cholinergic function through the inhibition of the acetylcholinesterase, a set of candidates was designed from a natural compound extracted from the cashew nutshell liquid, anacardic acid. In silico screening of this chemical library revealed a ligand that is more promising once it is correlated with an active drug through specific topological and electronic descriptors. The protein-ligand docking showed stable binding modes and the binding free energy computed for the active site of the receptor suggests that our ligand presents a potential biological response. Graphical Abstract Representation of the three dimensional structure of the AChE, showing the important binding sites of the Gorge and the conformation of the ligand.
本文探讨了用于治疗阿尔茨海默病的新型治疗药物的分子建模。本研究采用的治疗思路是胆碱能假说。为了通过抑制乙酰胆碱酯酶来正向调节胆碱能功能,从腰果壳液中提取的天然化合物——漆树酸设计了一组候选药物。对该化学文库进行计算机筛选后发现了一种配体,一旦通过特定的拓扑和电子描述符将其与活性药物相关联,该配体就更具前景。蛋白质-配体对接显示出稳定的结合模式,为受体活性位点计算的结合自由能表明我们的配体具有潜在的生物学反应。乙酰胆碱酯酶三维结构的图形摘要,展示了峡谷的重要结合位点和配体的构象。
