Evernimicin (SCH 27899) is a novel oligosaccharide antibiotic that belongs to the everninomicin family. Its antimicrobial activity results from interference with protein synthesis. In an experimental model of methicillin-resistant S. aureus endocarditis, evernimicin was not significantly more effective than vancomycin [70].
