Discovery of (aryloxopropenyl)pyrrolyl hydroxyamides as selective inhibitors of class IIa histone deacetylase homologue HD1-A

J Med Chem. 2003 Nov 6;46(23):4826-9. doi: 10.1021/jm034167p.

Abstract

Chemical manipulations performed on aroyl pyrrolyl hydroxyamides, a new class of HDAC inhibitors previously reported by us, led to (aryloxopropenyl)pyrrolyl hydroxyamides 3a-g. Such compounds, showing better inhibitory activity against maize HD1-A than HD1-B (two homologues of mammalian class IIa and I HDACs, respectively), are the first class of IIa-selective inhibitors (fold selectivity: 7-78). They could be useful as tools for probing the biology of these enzymes and eventually as new anticancer agents with low toxicity.
