Abstract

Nobel PDF inhibitors and novel methods for their use are provided.

Description

field of invention [0001] The present invention relates to the use of novel antibacterial compounds, and pharmaceutical compositions of these compounds as peptide deformylase inhibitors. Background of the invention [0002] Bacterial promoter methionyl tRNA is modified by methionyl tRNA formyltransferase (FMT) to generate formylmethionyl tRNA. Formylmethionine (f-met) then binds to the N-terminus of the newly generated polypeptide. Subsequently, the primary translation product is deformylated by polypeptide deformylase (PDF or Def) to generate N-methionyl polypeptide. Most intracellular proteins are further processed by methionine aminopeptidase (MAP) to generate mature peptides and free methionine, and this process goes on again and again. Both PDF and MAP are essential factors for bacterial growth. In addition, PDF is also a necessary condition for MAP activity. This series of reactions refers to the following methionine cycle (Figure 1). [0003] [0004] Fig...
