Synthesis and in vitro antibacterial activity of oxazolidine LBM-415 analogs as peptide deformylase inhibitors
摘要:
The drug resistant bacteria pose a severe threat to human health. The increasing resistance of those pathogens to traditional antibacterial therapy renders the identification of new antibacterial agents with novel antibacterial mechanisms an urgent need. In this study, a series of (2S)-N-substituted-1-[(formyhydroxyamino) methyl]-1-oxohexyl]-2-oxazolidinecarboxamides were designed, synthesized and evaluated for in vitro antibacterial activity. Most of these compounds displayed good activities against Gram-positive organisms comparable to reference agent LBM-415. Crown Copyright (C) 2010 Published by Elsevier Ltd. All rights reserved.

The present invention is directed to a process for preparing intermediates that are useful to prepare certain antibacterial N-formyl hydroxylamine compounds which are peptide deformylase inhibitors. The process makes use α β-lactam intermediate. Certain optically pure intermediates are also claimed.
A facile and a practical synthesis of peptide-deformylase inhibitor 1 is described using an acid-catalyzed aminolysis of β-lactam 12 with pyrrolidine 6 as the key transformation. In addition, simplified conditions for the conversion of a β-hydroxy acid to a β-lactam are reported.
