Cefotaxime (sodium salt)
Cefotaxime sodium (CAS 64485-93-4) is a third-generation cephalosporin antibiotic belonging to the β-lactam group, characterized by inhibition of bacterial cell-wall synthesis through binding to penicillin-binding proteins. In vitro analyses show strong inhibitory efficacy against various bacterial species; notably, cefotaxime exhibits an MIC below 0.1 μg/ml against Streptococcus pneumoniae. It also demonstrates high activity against Haemophilus influenzae, including β-lactamase-producing strains. In vivo mouse model studies revealed that combination therapy of cefotaxime with minocycline enhanced survival following Vibrio vulnificus infection compared to single-agent treatments. Clinically, cefotaxime has been evaluated in pneumonia therapy, demonstrating good tolerance and therapeutic utility in targeting susceptible bacterial pathogens.
