一般說明
Chemical structure: ß-lactam
應用
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.
生化／生理作用
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.
其他說明
Broad spectrum third generation cephalosporin antibiotic.
Keep container tightly closed in a dry and well-ventilated place.

In an innovative therapeutic exploitation against antibiotic-resistant Streptococcus pneumoniae, here we have evaluated the in vitro activity of a purified bacterially-encoded cell wall lytic enzyme, LytA (the major pneumococcal autolysin), and compared it with those of Cpl-1 and Pal (pneumococcal

The CTX-M β-lactamases are an increasingly prevalent group of extended-spectrum β-lactamases (ESBL). Point mutations in CTX-M β-lactamases are considered critical for enhanced hydrolysis of cefotaxime. In order to clarify the structural determinants of the activity against cefotaxime in CTX-M β-lactamases

In an attempt to determine the susceptibility breakpoints for amoxycillin, co-amoxiclav and cefotaxime in pneumococcal pneumonia, a neutropenic mouse model was established and tested with two strains having different susceptibility to penicillins and cefotaxime. With a penicillin-sensitive strain (MIC/MBC =
