| In vitro study | Piperacillin is a penicillin beta-lactam antibiotic used to treat bacterial infections caused by susceptible Gram-positive bacteria. "Penicillin" can refer to both the several isomers of penicillin and the group of antibiotics derived from penicillin. Piperacillin has in vitro antibacterial activity against Gram-positive and Gram-negative and aerobic and anaerobic bacteria. The bactericidal activity of Piperacillin, which inhibits bacterial cell wall synthesis, is regulated by the binding of Piperacillin to penicillin-binding protein (PBPs). Piperacillin inhibits the third and final stage of bacterial cell wall synthesis by binding to a specific penicillin-binding protein (PBPs) located within the bacterial cell wall. Piperacillin is stable to hydrolysis by various β-lactamases, including penicillinase, cephalosporinase, and extended-spectrum β-lactamases. |
