Description_x000D_ Application_x000D_ Phosphomycin, also known as Fosfomycin, is an antibiotic produced by Streptomyces fradiae. It is used to treat uncomplicated urinary tract infections. It is used for susceptibility studies of Klebsiella pneumoniae and to study in vitro susceptibility testing procedures for fosfomycin tromethamine._x000D_ Biochem/physiol Actions_x000D_ 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._x000D_ Other Notes_x000D_ 1g,5g,50g_x000D_ Keep container tightly closed in a dry and well-ventilated place.Keep in a dry place.
