    Avibactam sodium


    Avibactam sodium is a β-lactamase inhibitor without a β-lactam core that can inhibit class A and C enzymes, along with some class D enzymes. It is effective against Enterobacteriaceae.  Avibactam sodium can be used for strain manipulation and drug resistance studies.  

    Mechanism of ActionAvibactam is a nucleophilic serine enzyme inhibitor that contains a diazabicyclooctane (DBO) core, unlike the other β -lactamases, or PBPs (penicillin-binding protein) inhibitors, that contain a β -lactam ring.
    Eukaryotic Cell Culture ApplicationsAvibactam can restore the antimicrobial properties of partner cephalosporins in vitro against Enterobacteriaceae (Lagacé-Wiens et al, 2011).
