Peptide deformylase (PDF) is a metalloprotease catalyzing the removal of a formyl group from newly synthesized proteins. Thus inhibition of PDF activity is considered to be one of the most effective antibiotic strategies. Reported herein are the synthesis and structure-activity relationship studies of retro-amide inhibitors based on actinonin, a naturally occurring PDF inhibitor. Analysis of the structure-activity relationships led to the discovery of 7a, which exhibits potent enzyme inhibition and antibacterial activity against Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis.
