title: Helvecardins A and B, novel glycopeptide antibiotics. III. Biological properties.
abstract: Helvecardins (HVCs) A and B were strongly active against aerobic and anaerobic Gram-positive bacteria including methicillin-resistant Staphylococcus aureus (MRSA), but they were inactive against Gram-negative bacteria and fungi. Though HVC A showed only slightly stronger antimicrobial activity than beta-avoparcin (AVP), its in vivo protective activity against S. aureus infection in mice was greatly superior to AVP.
