Provided is a tau aggregation inhibitor which can sufficiently inhibit a tau protein from aggregating in cells. The inhibitor includes a 4-substituted catechol structure compound, having, at position 4 of its catechol ring, an electron-donating substituent R other than a hydrocarbon group, or a salt thereof The 4-substituted catechol structure compound is preferably 4-aminocatechol or 1,2,4-benzenetriol. Examples of tauopathies to which this inhibitor is applicable include AD, Down's syndrome, frontotemporal dementia, cotricobasal degeneration (CBD) and progressive supranuclear palsy (PSP).
本研究提供了一种 tau 聚集
抑制剂,它能够充分抑制 tau 蛋白在细胞中的聚集。该
抑制剂包括一种 4-取代
儿茶酚结构化合物,在其
儿茶酚环的第 4 位上具有除烃基以外的电子供能取代基 R,或其盐。这种
抑制剂适用的tauopathies包括AD、唐氏综合征、额颞叶痴呆、同侧基底变性(CBD)和进行性核上性麻痹(P
SP)。
