General description

Chemical structure: β-lactam

Application

Cloxacillin is a semisynthetic antibiotic in the same class as penicillin. Cloxacillin is used against staphylococci that produce β-lactamase. It is used to study the role of pH in antibiotic effectiveness and how oxgall, acid, and hydrogen peroxide stress effects the susceptibility of Bifidobacteria.

Biochem/physiol Actions

Cloxacillin interferes with the last stage of bacterial cell wall synthesis by binding to penicillin-binding proteins. This inhibits the necessary cross-linking and leads to autolysis of the bacteria by autolysins.

Other Notes

Keep container tightly closed in a dry and well-ventilated place.
