Product Description
Mechanism of Action
Clavulanic acid is a β‑lactamase inhibitor structurally related to penicillins but possessing minimal intrinsic antibacterial activity. It covalently binds serine β‑lactamases, generating inactive acyl‑enzyme intermediates. It restores activity of β‑lactam antibiotics against resistant organisms producing TEM, SHV and certain ESBL-type enzymes.
Benefits and Advantages
Used in inhibitor‑resistance research, β‑lactamase structural studies, combination‑drug PK/PD modelling, synergy evaluation and enzyme‑mechanism profiling of serine‑hydrolase inhibition.
Side Effects and Risks
Risks include GI discomfort, hypersensitivity, hepatic dysfunction and rash. Handle with β‑lactamase‑inhibitor precautions.
