说明

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

Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards

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.

其他说明

Broad spectrum third generation cephalosporin antibiotic.
