Histone Deacetylases are considered promising targets for cancer epigenetic therapy, and small molecules able to modulate their biological function have recently gained an increasing interest as potential anticancer agents. In spite of their potential application in cancer therapy, most HDAC inhibitors unselectively bind the several HDAC isoforms, giving rise to different side-effects. In this context, we have traced out the structural elements responsible of selective binding for the therapeutically relevant different HDAC isoforms. The structural analysis has been carried out by molecular modeling, docking in the binding pockets of HDAC1-4 and HDAC6-8, 36 inhibitors presenting a well defined selectivity for the different isoforms. As quick proof of evidence, we have designed, synthesized and experimentally tested three selective ligands. The experimental data suggest that the obtained structural guidelines can be useful tools for the rational design of new potent inhibitors against selected HDAC isoforms.
