Abstract: YopH plays a relevant role in three pathogenic species of Yersinia. Due to its importance in the prevention of the inflammatory response of the host, this enzyme has become a valid target for the identification and development of new inhibitors. In this work, an in-house library of 283 synthetic compounds was assayed against recombinant YopH from Yersinia enterocolitica. From these, four chalcone derivatives and one sulfonamide were identified for the first time as competitive inhibitors of YopH with binding affinity in the low micromolar range. Molecular modeling investigations indicated that the new inhibitors showed similar binding modes, establishing polar and hydrophobic contacts with key residues of the YopH binding site.
