一般描述
Chemical structure: ß-lactam
应用
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. It is a potential therapy of meningitis due to Staphylococcus aureus.
生化/生理作用
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.

Expression of methicillin resistance in heterogeneous strains of Staphylococcus aureus is enhanced by 2 to 5% NaCl in the medium and by selection with beta-lactam antibiotics. Resistance is associated with production of a penicillin-binding protein (PBP), PBP 2a, with low

In this study, an anti-amoxicillin single chain variable fragment (ScFv) antibody was evolved by directional mutagenesis of a contact amino acid residue based on the analysis of virtual mutation. Comparison with its parental ScFv, the mutant showed highly improved affinity
