Product Description
Mechanism of action
Carbenicillin is a broad‑spectrum β‑lactam antibiotic belonging to the carboxypenicillin class. It inhibits bacterial cell‑wall synthesis by binding to penicillin‑binding proteins (PBPs), preventing crosslinking of peptidoglycan layers. It is particularly active against *Pseudomonas* species and gram‑negative rods.
Benefits and advantages
Used in antibacterial‑mechanism research, PBP‑binding assays, β‑lactam resistance studies, gram‑negative metabolism modelling, biofilm‑formation studies and comparative β‑lactam SAR research.
Side effects and risks
Risks include hypersensitivity reactions, bleeding tendencies (platelet dysfunction), electrolyte disturbances due to sodium load, and nephrotoxicity. Handle with antimicrobial compound safety precautions.
