Discovery of piperazic acid peptide deformylase inhibitors with in vivo activity for respiratory tract and skin infections.
Bioorg.Med.Chem.Lett., 29:2410-2414, 2019

PubMed Abstract: 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.
