cefotaxime

Cefotaxime 是头孢类抗生素和耐内酰胺酶的头孢菌素，具有抗革兰氏阳性菌和革兰氏阴性菌的作用。

Cefotaxime sodium (Cefotaxim sodium salt) 是头孢类抗生素和耐内酰胺酶的头孢菌素，有抗革兰氏阳性菌和革兰氏阴性菌作用。

3-Desacetyl Cefotaxime lactone, the active metabolite of Cefotaxime, is derived from its sodium salt form, which is recognized as a third-generation cephalosporin antibiotic.

Cefotaxime-d3 是一种氘标记的 Cefotaxime，其为对 β-内酰胺酶稳定的头孢菌素，属于第三代头孢菌素抗生素，具有对多种革兰氏阳性菌及革兰氏阴性菌的广谱抗生素活性。

Desacetylcefotaxime is an active metabolite of the cephalosporin antibiotic cefotaxime .1It is active against 60 clinical isolates derived from patients with meningitis, includingH. influenzae,S. pneumoniae,S. agalactiae, andN. meningitidis(MIC90s = 0.008-0.12 μg/ml). 1.Jones, R.N.Cefotaxime and desacetylcefotaxime antimicrobial interactions.

Desacetylcefotaxime, Cefotaxime的一种体内代谢物，具有类似其母体化合物对多种需氧和厌氧细菌的体外抗菌活性。

Ceftizoxime, a third-generation cephalosporin effective against Gram-negative and Gram-positive bacteria, binds penicillin-binding proteins (PBPs) to inhibit the bacterial cell wall synthesis. It rather resembles cefotaxime in its properties but is not su

Desacetyl cefapirin is an active metabolite of the cephalosporin antibiotic cefapirin .1 Desacetyl cefapirin is active against E. coli, K. pneumoniae, P. mirabilis, and S. aureus with MIC values of 120, 24, 34, and 0.42 μg ml, respectively.References1.
