Dalbavancin is a second generation, semi-synthetic lipoglycopeptide antibiotic that is active against Gram-positive bacteria. It was designed to improve upon the natural glycopeptides currently available (vancomycina and teicoplanin) and was launched in 2014. It is used to combat the bacteria causing acute bacterial skin and skin structure infections.
| Mechanism of Action | Dalbavancin HCl disrupts cell wall biosynthesis. It binds to the D-alanyl-D-alanyl residue on growing peptidoglycan chains and prevents transpeptidation. Unlike naturally occurring glycopeptides, Dalbavancin can dimerize and anchors itself in the bacterial membrane whcih improves stabilizationa nd increases its affinity for peptidoglycan. |
| Microbiology Applications | Dalbavancin has more potent in vitro bactericidal activity than vancomycin or teicoplanin against many resistant organisms such as MRSA and Methicillin-resistant Staphylococcus epidermidis (MRSE). It is active in vitro against S. pneumonieae, S. pyogenes, vancomycin-Sensitive Enterococcus. |
