Structure-activity relationship analysis and therapeutic potential of peptide deformylase inhibitors.

Abstract

Peptide deformylase inhibitors (PDFIs) appear to be one of the most exciting classes of antibacterial agents discovered to date. Rapid progress in the development of PDFIs has been possible because peptide deformylase is a metalloprotease, and this class of enzymes shows a high degree of structure-function conservation, and because the most potent PDFIs are hydroxamate derivatives, a well known category of pharmacophores. The current challenge in structure-activity relationship analysis is obtaining molecules with potent in vivo antibacterial activity against a range of drug-resistant pathogens. The PDFIs currently in clinical trials target community-based bacterial infections, with a potential major pharmaceutical market.
