Beschreibung

Allgemeine Beschreibung

Chemical structure: ß-lactam

Anwendung

Nafcillin sodium is a narrow-spectrum β-lactam antibiotic. It is used to treat infections caused by Gram-positive bacteria, in particular, species of Staphylococci that are resistant to other penicillins. It has been used to study penicillin-binding proteins (PBPs), such as 2a, and heterogeneous expression of methicillin resistance in Staphylococcus aureus[1]. It is a potential therapy of meningitis due to Staphylococcus aureus[2].

Biochem./physiol. Wirkung

Nafcillin inhibits bacterial cell wall formation by inhibiting PBPs. The irreversible inhibition of the PBPs prevents the final crosslinking (transpeptidation) of the nascent peptidoglycan layer, which disrupts cell wall synthesis.
