cleavage of amyloid precursor protein by β-secretase (BACE1) is a key step in generating the N-terminal of β-amyloid (Aβ), which further forms into amyloid plaques that are considered as the hallmark of Alzheimer's disease. Inhibitors of BACE1 can reduce the levels of Aβ and thus have a therapeutic potential for treating the disease. We report here the identification of a series of small molecules bearing
β-分泌酶 (BACE1) 对淀粉样前体蛋白进行蛋白水解切割是生成 β-淀粉样蛋白 (Aβ) 的 N 端的关键步骤,其进一步形成被认为是阿尔茨海默病标志的淀粉样斑块。BACE1 抑制剂可以降低 Aβ 的水平,因此具有治疗该疾病的治疗潜力。我们在这里报告了一系列带有吲哚酰基胍核心结构的小分子作为有效的 BACE1 抑制剂的鉴定。最初的弱片段是通过虚拟筛选发现的,然后进行了先导优化。借助已发现的两种抑制剂(化合物 19 和 25)与 BACE1 的共晶结构,我们探索了吲哚和芳基周围的 SAR,并获得了几种 BACE1 抑制剂,其效力比最初命中的片段强约 1,000 倍。
