Description_x000D_ Biochem/physiol Actions_x000D_ Dalbavancin is a semisynthetic, vancomycin class lipoglycopeptide with antibacterial activity against a variety of gram-positive pathogens, including methicillin-resistant S. aureus & S. epidermidis (MRSA & MRSE), but not gram-negative or vancomycin-resistant enterococci that possess VanA gene. Similar to vancomycin and other class members (e.g. teicoplanin, telavancin, ramoplanin, and ritavancin), dalbavancin disrupts bateria cell wall formation and cell membrane integrity by targeting the D-alanyl-D-alanyl residues on the growing peptidoglycan chains, blocking transpeptidation and peptidoglycan elongation.
