fosfomycin brands

Molecular formula: C3H7O4P

Fosfomycin exerts its bactericidal effects by binding covalently to a cysteine in the active site of the UDP-N-acetylglucosamine enolpyruvyl transferase (MurA) enzyme, rendering it inactive. By preventing MurA from catalyzing the condensation of phosphoenolpyruvate (PEP) with UDP-N-acetylglucosamine (UNAG), fosfomycin inhibits the production of the peptidoglycan precursor UDP N-acetylmuramic acid (UDP-MurNAc). Ultimately, the first step of bacterial cell wall synthesis is disrupted. In _Escherichia coli_, fosfomycin gains entry into bacterial cells via two mechanisms: the L-alpha-glycerophosphate system and the hexose-6-phosphate transporter system. Fosfomycin also has important effects on cell adhesion. For example, the adhesion of bacterial cells to urinary epithelial cells is reduced in the presence of fosfomycin. The adhesion of _Streptococcus pneumoniae_ and _Haemophilus influenzae_ to respiratory epithelial cells is also reduced
