SW-100, a selective histone deacetylase 6 (HDAC6) inhibitor with an IC50 of 2.3 nM, shows at least 1000-fold selectivity for HDAC6 relative to all other HDAC isozymes. SW-100 displays a significantly improved ability to cross the blood-brain-barrier[1].
SW-100 (0.01-10 µM; 48 hours) shows obvious increase in the acetylated α-tubulin levels in a dose-dependent manner[1].
SW-100 (20 mg/kg; i.p.; twice a day for two days) ameliorates several memory and learning impairments including novel object recognition, temporal ordering, and coordinate and categorical spatial processing in mouse model of Fragile X syndrome[1].
