概览

Oritavancin is an antibacterial agent used to treat acute bacterial skin and skin structure infections caused by susceptible Gram-positive bacteria.

作用机制

The cell wall is vital for the survival and replication of bacteria, making it a primary target for antibiotic therapy. Oritavancin works against susceptible gram-positive organisms via three separate mechanisms. Firstly, it binds to the stem peptide of peptidoglycan precursors, inhibiting transglycosylation (polymerization). This process normally occurs during cell wall synthesis. Secondly, oritavancin inhibits crosslinking during bacterial cell wall biosynthesis via binding to cell wall pentaglycyl peptide bridging segments. Finally, this drug also acts by disrupting the bacterial cell membrane, interfering with its integrity, which eventually leads to cell death by various mechanisms.
