Clavulanate Potassium

Clavulanic acid is a beta-lactam antibiotic produced by several species of the genus Streptomyces. The free acid degrades and is isolated and maintained as either the sodium or potassium salt. Clavulanate is a weak antibiotic but is a potent inhibitor of beta- lactamases. In combination with penicillin and cephalosporins it shows potent synergistic activity. Clavulanic acid is a suicide inhibitor, covalently binding to a serine residue in the active site of the beta-lactamase. Source: Streptomyces sp.
