title: Chemical modification of antibiotic eremomycin at the asparagine side chain.
abstract: AA3-Carboxyeremomycin 2, obtained by selective hydrolysis of antibiotic eremomycin was used as a starting compound for the eremomycin chemical modifications at the asparagine side chain to be transformed into eremomycin AA3, AA7 bis-amides (3a-c). Bis-benzylamide 3b displayed an activity (8 microg/ml) against an E. faecium VanA strain.
