Description: SW-100 is a potent, selective, brain penetrable HDAC6 inhibitor. SW-100 demonstrates good brain penetrance, low-nanomolar potency for the inhibition of HDAC6 (IC50 = 2.3 nM), with at least a thousand-fold selectivity over all other class I, II, and IV HDAC isoforms. SW-100 upregulates α-tubulin acetylation with no effect on histone acetylation and selectively restores the impaired acetylated α-tubulin levels in the hippocampus of Fmr1-/- mice. SW-100 ameliorates several memory and learning impairments in Fmr1-/- mice, thus modeling the intellectual deficiencies associated with FXS,
