We have identified a potent, cell permeable and CNS penetrant class ha histone deacetylase (HDAC) inhibitor 22, with > 500-fold selectivity over class I HDACs (1,2,3) and similar to 150-fold selectivity over HDAC8 and the class IIb HDAC6 isoform. Dose escalation pharmacokinetic analysis demonstrated that upon oral administration, compound 22 can reach exposure levels in mouse plasma, muscle and brain in excess of cellular class Ha HDAC IC50 levels for similar to 8 h. Given the interest in aberrant class Ha HDAC function for a number of neurodegenerative, neuromuscular, cardiac and oncology indications, compound 22 (also known as CHDI-390576) provides a selective and potent compound to query the role of class ha HDAC biology, and the impact of class ha catalytic site occupancy in vitro and in vivo.
