Beschreibung

General description

Chemical structure: β-lactam

Application

Dicloxacillin is a β-lactamase resistant penicillin similar to oxacillin. Dicloxacillin has in vitro activity against gram-positive and gram-negative aerobic and anaerobic bacteria. It is resistant to penicillinase. It is used to study bacterial cell wall biosynthesis at the level of peptidogylcan cross-linking and to study mechanisms of penicillinase (β-lactamase) resistance. It is used to study phenylbutazone plasma binding and extracellular and intracellular killing of Staphylococcus aureus[1]

Biochem/physiol Actions

Docloxacillin binds to specific penicillin-binding proteins (PBPs) in the bacterial cell wall and therefore inhibits the last stage of bacterial cell wall synthesis. Cell lysis, mediated by bacterial cell wall autolytic enzymes, is the result. Dicloxacillin may interfere with autolysin inhibitors .
