The novel therapeutic strategy of vilazodone-donepezil chimeras as potent triple-target ligands for the potential treatment of Alzheimer's disease with comorbid depression
pharmacophores of the antidepressant vilazodone (5-HT1Areceptor partial agonist and serotonin transporter inhibitor) and the anti-AD drug donepezil (acetylcholinesterase inhibitor) together to develop a series of multi-target-directed ligands for potential therapy of the comorbidity of AD and depression. Accordingly, 55 vilazodone-donepezil chimeric derivatives were designed and synthesized, and their triple-target
抑郁症是阿尔茨海默病 (AD) 最常见的共病精神症状之一,迄今为止还没有专门为此目的批准的有效药物。在此,我们提出了一种新的治疗策略,将抗抑郁药维拉佐酮(5-HT 1A受体部分激动剂和5-羟色胺转运蛋白抑制剂)和抗AD药物多奈哌齐(乙酰胆碱酯酶抑制剂)的关键药效团结合在一起,开发了一系列多靶点。用于潜在治疗 AD 和抑郁症共病的定向配体。因此,设计并合成了 55 种维拉佐酮-多奈哌齐嵌合衍生物,以及它们对乙酰胆碱酯酶 5-HT 1A的三靶点活性。受体和血清素转运蛋白进行了系统评估。其中,化合物5在体外表现出很强的三靶点生物活性、低hERG钾通道抑制和可接受的脑分布。重要的是,口服 5 mg/kg 的化合物5二盐酸盐可显着减轻小鼠模型的抑郁症状并改善认知功能障碍。简而言之,这些结果突出了维拉佐酮-多奈哌齐嵌合体作为治疗 AD 和抑郁症合并症的前瞻性治疗方法。
Novel Vilazodone–Tacrine Hybrids as Potential Multitarget-Directed Ligands for the Treatment of Alzheimer’s Disease Accompanied with Depression: Design, Synthesis, and Biological Evaluation
complications of Alzheimer’sdisease (AD), affecting up to 50% of the patients. A novel series of hybrid molecules were designed and synthesized by combining the pharmacophoric features of vilazodone and tacrine as potential multitarget-directed ligands for the treatment of AD with depression. In vitro biological assays were conducted to evaluate the compounds; among the 30 hybrids, compound 1e showed
