Description and Uses
Cloxacillin is a β-lactam antibiotic and a derivative of oxacillin . It is active against clinical isolates of the Gram-positive bacteria S. aureus and S. epidermidis (MICs = 0.004-0.4 and 0.1-0.8 μg/ml, respectively) but not 34 Gram-negative bacteria (MICs = >128 μg/ml for all). Cloxacillin binds to S. aureus penicillin-binding protein 1 (PBP1), PBP2, PBP3, and PBP4 (IC50s = 0.04, 0.12, 0.21, and 2.5 μg/ml, respectively). It also binds to recombinant type Ib penicillinase, as well as P. vulgaris and C. freundii cephalosporinase (Kis = 15, 0.27, and 0.027 μM, respectively). Cloxacillin decreases the number of staphylococci in the mammary gland in a mouse model of acute, but not chronic, mastitis induced by Staphylococcus infection.
Ropivacaine (R675000) metabolite.
