Abstract

Simple and scalable synthetic approach was used for the preparation of thirteen novel tacrine derivatives consisting of tacrine and N-aryl-piperidine-4-carboxamide moiety connected by a five-methylene group linker. An anti-Alzheimer disease (AD) potential of newly designed tacrine derivatives was evaluated against two important AD targets, acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). In vitro pharmacological evaluation showed strong ChE inhibitory activity of all compounds, with IC values ranging from 117.5 to 455 nM for AChE and 34 to 324 nM for BuChE. As a representative of the series with the best cytotoxicity / ChE inhibitory activity ratio, expressed as the selectivity index (SI), 2-chlorobenzoyl derivative demonstrated mixed-type inhibition on AChE and BuChE, suggesting binding to both CAS and PAS of the enzymes. It also exhibited antioxidant capacity and neuroprotective potential against amyloid-β (Aβ) toxicity in the culture of neuron-like cells. In-depth computational analysis corroborated well with in vitro ChE inhibition, illuminating that all compounds exhibit significant potential in targeting both enzymes. Molecular dynamics (MD) simulations revealed that 2-chlorobenzoyl derivative, created complexes with AChE and BuChE that demonstrated sufficient stability throughout the observed MD simulation. Computationally predicted ADME properties indicated that these compounds should have good blood-brain barrier (BBB) permeability, an important factor for CNS-targeting drugs. Overall, all tested compounds showed promising pharmacological behavior, highlighting the multi-target potential of 2-chlorobenzoyl derivative which should be further investigated as a new lead in the drug development process.

摘要

采用简单且可扩展的合成方法制备了13种新型他克林衍生物,这些衍生物由他克林和通过五亚甲基连接基相连的N-芳基哌啶-4-甲酰胺部分组成。针对两个重要的阿尔茨海默病(AD)靶点,即乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BuChE),评估了新设计的他克林衍生物的抗AD潜力。体外药理学评估显示,所有化合物均具有较强的胆碱酯酶抑制活性,AChE的IC值范围为117.5至455 nM,BuChE的IC值范围为34至324 nM。作为该系列中细胞毒性/胆碱酯酶抑制活性比最佳(以选择性指数(SI)表示)的代表,2-氯苯甲酰衍生物对AChE和BuChE表现出混合型抑制作用,表明其与酶的催化活性位点(CAS)和外周活性位点(PAS)均有结合。它还在类神经元细胞培养中表现出抗氧化能力和针对淀粉样β蛋白(Aβ)毒性的神经保护潜力。深入的计算分析与体外胆碱酯酶抑制结果吻合良好,表明所有化合物在靶向这两种酶方面均具有显著潜力。分子动力学(MD)模拟显示,2-氯苯甲酰衍生物与AChE和BuChE形成的复合物在整个观察到的MD模拟过程中表现出足够的稳定性。计算预测的药物代谢动力学(ADME)性质表明,这些化合物应具有良好的血脑屏障(BBB)通透性,这是中枢神经系统靶向药物的一个重要因素。总体而言,所有测试化合物均表现出有前景的药理行为,突出了2-氯苯甲酰衍生物的多靶点潜力,应在药物开发过程中作为新的先导化合物进一步研究。
