precursor protein (APP) metabolism is deregulated in Alzheimer’s disease. Indeed, CQ modifies amyloid precursor protein (APP) metabolism by precluding the release of amyloid-beta peptides (Aβ), which accumulate in the brain of Alzheimer patients to form the so-called amyloid plaques. We showed that AQ and analogs have similar effects although having a higher cytotoxicity. Herein, two new series of
氯喹啉支架是抗疟疾药物的特征,例如氯喹(CQ)或阿莫二喹(AQ)。还描述了这些药物对against病毒病,HCV,EBV,埃博拉病毒,癌症,帕金森氏症或阿尔茨海默氏病的潜在效力。淀粉样前体蛋白(APP)的代谢在阿尔茨海默氏病中被放松调节。实际上,CQ通过阻止淀粉样蛋白β肽(Aβ)的释放来修饰淀粉样蛋白前体蛋白(APP)的代谢,该蛋白积聚在阿尔茨海默病患者的大脑中,形成所谓的淀粉样蛋白斑。我们显示,尽管AQ和类似物具有更高的细胞毒性,但它们具有相似的作用。在此,通过用2-氨基甲基苯胺和2-氨基甲基苯基取代AQ的7-氯喹啉-4-胺部分,合成了两个新的系列化合物。它们的结构活性关系基于它们调节APP代谢,Aβ释放的能力以及类似于CQ的细胞毒性。两种化合物图15a,16a显示了对APP代谢的重新导向,即减少Aβ肽释放(与AQ处于同一范围内),并且APP羧基末端片段(CTFα和AICD)的稳定性提高
