The aggregation of β-amyloid peptides is associated to neurodegeneration in Alzheimer’s disease (AD) patients. Consequently, the inhibition of both oligomerization and fibrillation of β-amyloid peptides is considered a plausible therapeutic approach for AD. Herein, the synthesis of new naphthalene derivatives and their evaluation as anti-β-amyloidogenic agents are presented. Molecular dynamic simulations
β-淀粉样肽的聚集与阿尔茨海默氏病(AD)患者的神经退行性疾病有关。因此,抑制β-淀粉样肽的低聚和原纤维化被认为是AD的合理治疗方法。在此,提出了新的萘衍生物的合成及其作为抗β淀粉样生成剂的评价。分子动力学模拟预测了化合物,Aβ1-42肽和原纤维之间热力学稳定的复合物的形成。在人小胶质细胞中,这些化合物抑制Aβ1-42肽的聚集。铅化合物8在小鼠脑离体测定中显示出对淀粉样斑块的高亲和力,并具有足够的log Poct / PBS值。化合物8还改善了3xTg-AD雌性小鼠大脑的认知功能并降低了海马β-淀粉样蛋白负担。总之,我们的结果表明8可能是AD的新型治疗剂。
