Through drug discovery strategies of repurposing and redeveloping existing drugs, a series of novel tadalafil derivatives were rationally designed, synthesized, and evaluated to seek dual-target AChE/PDE5 inhibitors as good candidate drugs for Alzheimer’s disease (AD). Among these derivatives, 1p and 1w exhibited excellent selective dual-target AChE/PDE5 inhibitory activities and improved blood-brain barrier (BBB) penetrability. Importantly, 1w·Cit (citrate of 1w) could reverse the cognitive dysfunction of scopolamine-induced AD mice and exhibited an excellent effect on enhancing cAMP response element-binding protein (CREB) phosphorylation in vivo, a crucial factor in memory formation and synaptic plasticity. Moreover, the molecular docking simulations of 1w with hAChE and hPDE5A confirmed that our design strategy was rational. In summary, our research provides a potential selective dual-target AChE/PDE5 inhibitor as a good candidate drug for the treatment of AD, and it could also be regarded as a small molecule probe to validate the novel AD therapeutic approach in vivo.

口服可利用的第一代乙酰胆碱酯酶（AChE）和磷酸二酯酶5（PDE5）的双目标选择性抑制剂的设计，合成和生物学评估

通过重新利用和重新开发现有药物的药物发现策略，合理地设计，合成和评估了一系列新型他达拉非衍生物，以寻找双靶点AChE / PDE5抑制剂作为阿尔茨海默氏病（AD）的良好候选药物。在这些衍生物中，1p和1w表现出优异的选择性双靶AChE / PDE5抑制活性和改善的血脑屏障（BBB）渗透性。重要的是1w·Cit（柠檬酸盐为1w）可以逆转东pol碱诱导的AD小鼠的认知功能障碍，并在增强体内cAMP反应元件结合蛋白（CREB）磷酸化方面表现出优异的作用，这是记忆形成和突触可塑性的关键因素。此外，与hAChE和hPDE5A的1w分子对接模拟证实了我们的设计策略是合理的。总而言之，我们的研究提供了一种潜在的选择性双靶AChE / PDE5抑制剂，作为治疗AD的良好候选药物，它也可以被视为小分子探针，以验证体内新颖的AD治疗方法。
