Requires at least a dipeptide for an efficient rate of reaction. N-terminal L-methionine is a prerequisite for activity but the enzyme has broad specificity at other positions (By similarity).[HAMAP-Rule:MF_00163] Publication Abstract from PubMed The discovery of a novel series of peptide deformylase inhibitors incorporating a piperazic acid amino acid found in nature is described. These compounds demonstrated potent in vitro enzymatic potency and antimicrobial activity. Crystal structure analysis revealed the piperazic acid optimized a key contact with the PDF protein that accounted for the increased enzymatic potency of these compounds. We describe lead optimization of the P3' region of the series that resulted in a compound with good potency against three target organisms. One molecule showed in vivo efficacy in a rat respiratory infection model but ultimately did not meet candidate progression criteria.
