Epigenetic regulation of gene expression using histone deacetylase (HDAC) inhibitors is a promising strategy for developing new anticancer agents. The most common HDAC inhibitors are hydroxamates, which, though highly potent, have limitations due to their poor pharmacokinetic properties and lack of isoform selectivity. Trifluoromethylketones (TFMK) developed as alternatives to hydroxamates are rapidly metabolized to inactive trifluoromethyl alcohols in vivo, which prevented their further development as potential drug candidates. In order to overcome this limitation, we designed trifluoropyruvamides (TFPAs) as TFMK surrogates. The presence of an additional electron withdrawing group next to the ketone carbonyl group made the hydrate form of the ketone more stable, thus preventing its metabolic reduction to alcohol in vivo. In addition, this structural modification reduces the potential of the TFMK group to act as a covalent warhead to eliminate off-target effects. Additional structural changes in the cap group of the inhibitors gave analogues with IC |
