由 tau 蛋白聚集体组成的神经原纤维缠结的扩散是阿尔茨海默病和相关神经退行性疾病的标志。 tau 蛋白的早期寡聚涉及构象重组为平行 β 片层结构以及超分子组装为有毒原纤维。尽管需要选择性的 tau 增殖抑制剂,但富含 β 的蛋白质组装体本质上很难用小分子靶向。在这里,我们描述了一种模仿 tau 内易于聚合的模块的极简方法。我们进行了主链残基扫描,结果表明酰胺 N-氨基化完全消除了这些肽自我聚集的倾向,使它们成为 tau R2 和 R3 结构域有序 β 链的可溶模拟物。几种 N-氨基肽 (NAP) 在体外抑制 tau 原纤维形成。我们进一步证明,NAP 12和13通过与细胞外 tau 的单体或纤维形式相互作用,可有效阻断内源 tau 的细胞播种。拟肽12血清稳定,对神经元细胞无毒,并且相对于 Aβ 42选择性抑制 tau 纤维化。我们的先导 NAP 的结构分析显示 N-氨基施加了相当大的构象限制。所描述的骨架
