摘要: A tau aggregation inhibitor 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).

摘要: A tau aggregation inhibitor reduces tau aggregation in cells. The tau aggregation inhibitor can include a catechol structure-containing compound or a salt thereof, and the catechol structure-containing compound can be one of isoprenaline, dopamine, dobutamine, levodopa, levodopa/carbidopa, trimetoquinol, hexoprenaline, methyldopa, and droxidopa. One example of the catechol structure-containing compound is isoprenaline, which can be d-enantiomer of isoprenaline or d/l-racemic mixture of isoprenaline. Tauopathies to be prevented or treated by the inhibitor include AD, Down's syndrome, Pick's disease, corticobasal degeneration, and progressive supranuclear palsy.
