MSH: One of the PENICILLINS which is resistant to PENICILLINASE but susceptible to a penicillin-binding protein. It is inactivated by gastric acid so administered by injection.,CSP: semisynthetic penicillin used as an antibacterial in resistant staphylococcal infections.,NCI: A semisynthetic, narrow spectrum beta-lactamase-resistant penicillin antibiotic with bactericidal and beta-lactamase resistant activity. Methicillin binds to specific penicillin-binding proteins (BPBs) on the bacterial cell wall, thereby preventing the cross-linkage of peptidoglycans, which are critical components of the bacterial cell wall. This leads to an interruption of the bacterial cell wall and causes bacterial lysis.
