treatment targeting acetylcholinesterase (AChE). Inhibition of phosphodiesterase 5A (PDE5A) has recently been validated as a potentially novel therapeutic approach for Alzheimer’s disease (AD). In this work, series of new compounds were designed, synthesized and evaluated as dual cholinesterase and PDE5A inhibitor. Biological results revealed that some of these compounds display good biological activities against
随着分子生物学和技术的最新研究进展,关于阿尔茨海默氏病(AD)进展的多种可信假说已被提出。多靶点药物已经成为AD的创新治疗方法。当前针对AD患者的临床治疗主要是针对乙酰胆碱酯酶(AChE)的姑息治疗。磷酸二酯酶5A(PDE5A)的抑制作用最近已被证实是阿尔茨海默氏病(AD)的一种潜在的新型治疗方法。在这项工作中,设计,合成和评估了一系列新化合物,作为双胆碱酯酶和PDE5A抑制剂。生物学结果表明,其中一些化合物对AChE表现出良好的生物学活性,IC 50值约为44.67–169.80 nM(多奈哌齐IC 5050.12 nM)。值得注意的是,化合物12表现出对PDE5A的有效活性,IC 50值约为50μM(sildenafil IC 50为12.59μM),其中一些化合物在体外对A549细胞的毒性较低。
