PDF Inhibitors

PDF inhibitors primarily target peptide deformylase (PDF), an enzyme crucial for bacterial protein synthesis. The inhibition of PDF is achieved predominantly by binding to the active site of the enzyme, thereby decreasing its interaction with substrate peptides. For instance, Actinonin, a natural product inhibitor, has a mode of action centered on its binding to the PDF active site. Similarly, compounds like BB-83698 and LBM-415 (NVP PDF-713) follow this mechanism of action, with structural designs either inspired by or improved upon from the structure of Actinonin.GM6001, primarily known for its role as a matrix metalloproteinase inhibitor, also displays inhibitory effects on PDF, showcasing that some compounds can act upon multiple targets. The majority of the other listed compounds, including RB-005, BB-3497, and GSK1322322, function by occupying the enzyme's active site, effecting how substrate peptides access it.
