Novel N-formyl hydroxylamine compounds and their derivatives are disclosed. These N-formyl hydroxylamine compounds inhibit peptidyl deformylase (PDF), an enzyme present in prokaryotes. The compounds are useful as antimicrobials and antibiotics. The compounds of the invention display selective inhibition of peptidyl deformylase versus other metalloproteinases such as MMPs. Methods of preparation and use of the compounds are also disclosed.
A practical synthesis of the peptide deformylase inhibitor LBM415, (2S)-N-(5-fluoro-1-oxido-2-pyridinyl)-1-[(2R)-2-[(formylhydroxyamino)methyl]-1-oxohexyl]-2-pyrrolidinecarboxamide, magnesium salt 11, is described. The key chiral intermediate, (2S)-N-(5-fluoro-2-pyridinyl)-1-[(2R)-2-[[formyl(phenylmethoxy)amino]methyl]-1-oxohexyl]-2-pyrrolidinecarboxamide 8, was made by coupling the corresponding amino
Certain N-formyl hydroxylamine compounds, such as N-[1-oxo-2-alkyl-3-(N-hydroxyformamido)-propyl]-(carbonylamino-aryl or -heteroaryl)-azacyclo4-7alkanes or thiazacyclo4-7alkanes or imidazacycIo4-7alkanes are useful in the treatment of bacterial infections. Disclosed are crystalline salts of such compounds of formula (I), wherein M is a mono- or di-valent metal; a is ½ or 1.
