A series of 2-(3-arylureido)pyridines and 2-(3-benzylureido)pyridines were synthesized and evaluated as potential modulators for amyloid beta (Aβ)-induced mitochondrial dysfunction in Alzheimer's disease (AD). The blocking activities of forty one small molecules against Aβ-induced mitochondrial permeability transition pore (mPTP) opening were evaluated by JC-1 assay which measures the change of mitochondrial
合成了一系列的2-(3-芳基脲基)吡啶和2-(3-苄基脲基)吡啶,并将其评估为淀粉样β(Aβ)诱导的阿尔茨海默氏病(AD)中的线粒体功能障碍的潜在调节剂。通过测量线粒体膜电位(ΔΨm)变化的JC-1分析评估了41个小分子对Aβ诱导的线粒体通透性转变孔(mPTP)开口的阻断活性。25种化合物对Aβ诱导的mPTP开放的抑制活性优于标准环孢菌素A(CsA)。就线粒体和细胞安全性而言,已鉴定出六种命中化合物可能是安全的,并对其对Aβ诱导的ATP产生的恶化和细胞毒性的保护作用进行了评估。其中,化合物7fb已被鉴定为保护神经元细胞免受67%的神经细胞毒性和43%的5μM浓度的Aβ诱导的线粒体ATP抑制抑制的先导化合物。使用CDocker算法,分子对接模型以亲环蛋白D(CypD)受体作为mPTP的主要成分,为这些化合物提供了一种可能的结合模式。因此,本报告提出化合物7fb作为一种新的非肽基mPTP阻断剂
