性能描述

Biochem/physiol Actions
Antibiotic that concentrates in kidney and bladder; reduces nephrotoxicity and ototoxicity of platinum-containing anti-tumor agents. Fosfomycin is a phosphoenolpyruvate analog that irreversibly inhibits UDP-GlcNAc enolpyruvyl tranferase (MurA), an enzyme involved in bacterial cell wall biosynthesis. As a result, the production of N-acetylmuramic acid, an essential element of the peptidoglycan cell wall, is inhibited.

Application
Phosphomycin, also known as Fosfomycin, is an antibiotic produced by Streptomyces fradiae. It is used to treat uncomplicated urinary tract infections and to reduce nephrotoxicity and ototoxicity of platinum-containing anti-tumor agents. It is used for susceptibility studies of Klebsiella pneumoniae and to study in vitro susceptibility testing procedures for fosfomycin tromethamine.

用途：磷霉素抑制细菌细胞壁的早期合成，其分子结构与磷酸烯醇丙酮酸相似，故可竞争同一转移酶，使细菌细胞壁的合成受到阻抑而导致细菌死亡。作用于敏感菌后，电镜观察发现细菌形态有明显改变，中膈细胞壁增厚、弯曲和不规则，细胞壁变薄或消失。
