in drug discovery for Alzheimer's disease (AD), resulting in many small molecules and biological drug candidates. Most of the drugs marketed for AD are cholinergic. Herein, we report our efforts in the discovery of cholinesterases inhibitors (ChEIs) as multi-target-directed ligands. A series of tacrine-ferulic acid hybrids have been designed and synthesised. All these compounds showed potent acetyl-(AChE)
长期以来,胆碱能假说一直是阿尔茨海默氏病(AD)药物发现中的“极星”,导致了许多小分子和生物候选药物。市场上大多数用于AD的药物都是胆碱能的。在此,我们报告了我们在胆碱酯酶抑制剂(ChEIs)作为多靶标定向配体的发现中所做的努力。已经设计并合成了一系列他克林-阿魏酸杂种。所有这些化合物均显示出有效的乙酰基(AChE)和丁酰胆碱酯酶(BuChE)抑制作用。其中,最佳化合物10g是最有效的抗AChE抑制剂(电泳(eeAChE)半数最大抑制浓度(IC50)= 37.02 nM),它也是对BuChE的强抑制剂(马血清(eqBuChE)IC50 = 101.40 nM)。此外,它还能抑制淀粉样β蛋白自我聚集65。25μM时为49%。在随后的东碱诱导的体内AD模型中,化合物10g明显改善了认知障碍,并在肝毒性评估中显示出初步的安全性。这些数据表明化合物10g在针对AD的药物发现过程中是有希望的多功能剂。
