说明

头孢菌素类强效β-内酰胺酶耐药抗生素。对革兰氏阳性和革兰氏阴性生物（包括革兰氏阴性厌氧菌）具有活性。抑制细胞壁合成。
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。

一般描述

Potent β-lactamase-resistant antibiotic of cephalosporin class. Active against Gram-positive and Gram-negative organisms, including Gram-negative anaerobes. Inhibits cell wall 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.
Primary Target
Gram-positive
Secondary Target
Gram-negative
