Potent Histone Deacetylase Inhibitors Derived from 4‑(Aminomethyl)‑<i>N</i>‑hydroxybenzamide with High Selectivity for the HDAC6 Isoform
A screen for HDAC6 inhibitors identified
acyl derivatives of 4-(aminomethyl)-<i>N</i>-hydroxybenzamide
as potent leads with unexpected selectivity
over the other subtypes. We designed and synthesized constrained heterocyclic
analogues such as tetrahydroisoquinolines that show further enhanced
HDAC6 selectivity and inhibitory activity in cellular assays. Selectivity
may be attributed to the benzylic spacer more effectively accessing
the wider channel of HDAC6 compared to other HDAC subtypes as well
as hydrophobic capping groups interacting with the protein surface
near the rim of the active site
