说明

头孢噻肟钠盐已被用作抗生素敏感性试验（AST）方法中的试验抗生素。它也被用作抗生素去除O中的细菌。金牛座文化。
头孢噻肟通过与青霉素结合蛋白（PBP）结合来抑制细菌细胞壁合成，所述青霉素结合蛋白抑制细菌细胞壁中肽聚糖合成的最终转肽步骤。结果，由于细胞壁自溶酶，细菌裂解。
头孢噻肟是一种头孢菌素抗生素，对革兰氏阴性菌和革兰氏阳性菌均有活性。另外，头孢噻肟阻断蓝细菌的分裂。它还具有抑制低等植物细胞器/质体的细胞分裂的能力，例如青光眼植物的光合细胞器和苔藓植物的叶绿体。

一般描述

Chemical structure: ß-lactam

应用

Cefotaxime sodium salt has been used as an test antibiotic in antibiotic susceptibility testing (AST) methods. It has also been used as an antibiotic to remove bacteria from O. tauri cultures.

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.

Cefotaxime, a cephalosporin antibiotic, is active against both gram-negative and gram-positive bacteria. In addition, cefotaxime blocks the division of cyanobacteria. It also has an ability to inhibit the cell division of lower plant organelles/plastids such as the photosynthetic organelles of glaucophytes and chloroplasts of bryophytes.

其他说明

Broad spectrum third generation cephalosporin antibiotic.
