Description

General description

Chemical structure: β-lactam

Application

Cefotaxim has been used to find new residues involved in cefotaxime hydrolysis in CTX-M β-lactamases, to study antibiotic-susceptible and -resistant Streptococcus pneumoniae infections, and to study pneumococcal pneumonia and the pharmokinetics of various treatments. It may be used to study the effects of binding and inhibition of penicillin binding protein 2 (PBP2) on bacterial mucopeptide synthesis.

Biochem/physiol Actions

Cefotaxim inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls. As a result, bacteria lyse due to cell wall autolytic enzymes.

Mode of Action: Inhibits bacterial cell wall synthesis.

Other Notes

Broad spectrum third generation cephalosporin antibiotic.

Keep container tightly closed in a dry and well-ventilated place.
