Alzheimer’s disease (AD) is one of the most devastating neurodegenerative disorders, characterized by multiple pathological features. Therefore, multi-target drug discovery has been one of the most active fields searching for new effective anti-AD therapies. Herein, a series of hybrid compounds are reported which were designed and developed by combining an aryl-sulfonamide function with a benzyl-piperidine moiety, the pharmacophore of donepezil (a current anti-AD acetylcholinesterase AChE inhibitor drug) or its benzyl-piperazine analogue. The in vitro results indicate that some of these hybrids achieve optimized activity towards two main AD targets, by displaying excellent AChE inhibitory potencies, as well as the capability to prevent amyloid-β (Aβ) aggregation. Some of these hybrids also prevented Aβ-induced cell toxicity. Significantly, drug-like properties were predicted, including for blood-brain permeability. Compound 9 emerged as a promising multi-target lead compound (AChE inhibition (IC50 1.6 μM); Aβ aggregation inhibition 60.7%). Overall, this family of hybrids is worthy of further exploration, due to the wide biological activity of sulfonamides.
阿尔茨海默病(AD)是最具破坏性的神经退行性疾病之一,其特征是多种病理特征。因此,多靶点药物发现一直是寻找新有效抗AD疗法最活跃的领域之一。在这里,报道了一系列杂合化合物,这些化合物是通过将芳基磺酰胺功能与苯基哌啶基团结合设计和开发的,这是多奈哌齐(一种当前的抗AD乙酰胆碱酯酶AChE抑制剂药物)或其苯基哌嗪类似物的药效团。体外结果表明,其中一些杂合物实现了优化活性,对两个主要的AD靶点具有出色的AChE抑制活性,以及预防淀粉样蛋白β(Aβ)聚集的能力。其中一些杂合物还预防了Aβ诱导的细胞毒性。值得注意的是,预测了药物样性质,包括血脑屏障通透性。化合物9被确定为一种有前景的多靶点先导化合物(AChE抑制(IC50 1.6 μM);Aβ聚集抑制60.7%)。总的来说,这类杂合物家族值得进一步探索,因为磺胺类化合物具有广泛的生物活性。
