BB-3497
BB-3497 is a potent, orally active and selective peptide deformylase (PDF) inhibitor. BB-3497 is highly selective for PDF (IC50 = 7 nM for E. coli PDF.Ni) over the other mammalian metalloenzymes (MMP-1/2/3/7 and enkephalinase). BB-3497 exhibits potent activity against gram-positive bacteria and some gram-negative pathogens. BB-3497 protects mice from infection in systemic models of Staphylococeus aureus. BB-3497 can be used for anti-bacterial infection research.

Biological Activity
BB-3497 binds to PDF such that the oxygen atoms of its N-formyl-hydroxylamine group occupy the positions of the two Ni-bound water molecules observed in the PDF-Met-Ala-Ser product complex[1].
BB-3497 shows superior in vitro antibacterial activity against E. coli DH5α and E. coli BL21(DE3) strains harboring a control plasmid (pET24) or pET24-PDF, with MIC values of 4, 8, 32, and 128 μg/mL, but shows an MIC of >128 μg/mL against an E. coli formyltransferase mutant, confirming that its antibacterial action is mediated through PDF inhibition[1].
BB-3497 (4-8x MIC, 24 h) results in <1-log-unit decreases in viable counts of S. aureus and E. coli, conforming its antibacterial effect[1].
BB-3497 (2-4x MIC, 24 h) results in resistant mutants at frequencies of 1 x 10-7 for E. coli and 2 x 10-7 for S. aureus, with high-level resistance conferred by mutations in the fmt gene and low-level resistance exhibited by mutants having a wild-type def-fmt operon[1].
