New Pyrrole-based Histone Deacetylase Inhibitors: Binding Mode, Enzyme- and Cell-based Investigations

Aroyl-pyrrolyl-hydroxy-amides (APHAs) are a class of synthetic HDAC inhibitors described by us since 2001. Through structure-based drug design, two isomers of the APHA lead compound 1, the 3-(2-benzoyl-1-methyl-1H-pyrrol-4-yl)-N-hydroxy-2-propenamide 2 and the 3-(2-benzoyl-1-methyl-1H-pyrrol-5-yl)-N-hydroxy-2-propenamide 3 (iso-APHAs) were designed, synthesized and tested in murine leukemia cells as antiproliferative and cytodifferentiating agents. To improve their HDAC activity and selectivity, … Continued
