Abstact

Herein we report an in vitro kinetic evaluation against the most relevant human carbonic anhydrase (hCA, EC 4.2.1.1) isoforms (I, II, IX and XII) of a small series of lactate dehydrogenase (LDH, EC 1.1.1.27) inhibitors. All compounds contain a primary sulfonamide zinc-binding group (ZBG) substituted with the 2-thio-6-oxo-1,6-dihydropyrimidine scaffold. By means of X-ray crystallographic experiments we explored the ligand-enzyme binding modes, thus highlighting the contribution of the 2-thio-6-oxo-1,6-dihydropyrimidine moiety to the stabilization of the complex.
