are synthesized via an indirect pathway involving side chain amidation of misacylated glutamyl-tRNAGln (Glu-tRNAGln) and/or aspartyl-tRNAAsn (Asp-tRNAAsn) by an amidotransferase. A series of chloramphenicolanalogs have been synthesized and evaluated as inhibitors of Helicobacter pylori GatCAB amidotransferase. Compound 7a was identified as the most active competitive inhibitor of the transamidase activity
