    Clavulanic Acid Potassium w/ Cellulose (1:1)

    ₩356,647.50 - ₩1,117,495.50

    Clavulanate Acid Potassium w/ Cellulose (1:1)  is a stable salt preparation of Clavulanic Acid, a natural, low-molecular weight β-lactam antibiotic.  It has weak, broad-spectrum activity but offers synergistic antibacterial activity with penicillins and cephalosporins for greater efficacy against β -lactam resistant strains. 

     We also offer:

    • Clavulanate Lithium (C064)
    • Clavulanic Acid Potassium (C232)
    Mechanism of ActionClavulanate is a potent suicide inhibitor of β -lactamases. It forms a covalent bond with a serine residue in the enzyme’s active site. Inhibition is time-dependent and irreversible. Clavulanic acid β-lactam antibiotics bind and inhibit PBPs (penicillin binding protein) thus inhibiting bacterial cell wall synthesis.
    Microbiology ApplicationsClavulanic acid had poor activity against S.aureus, Enterobacteriaceae, and P. aeruginosa. However, it can act synergistically with penicillins and cephalosporins to inhibit β -lactamase-producing S. aureus and Enterobacteriaceae.
