Florfenicol

Florfenicol is a broad-spectrum fluorinated antibiotic and a derivative of thiamphenicol (Cay-21357). It is active against human clinical isolates of enteric bacteria, including E. coli, Klebsiella, Enterobacter, Citrobacter, P. mirabilis, and Salmonella (MIC50s = 6.3-12.5 µg/ml). Florfenicol is also active against clinical isolates of various bovine and porcine respiratory tract pathogens, including P. multocida, A. pleuropneumoniae, and B. bronchiseptica (MIC50s = 0.25-4 µg/ml). It inhibits peptidyl transferase activity in 70S ribosomes isolated from E. coli when used at a concentration of 1 mM. Formulations containing florfenicol have been used in the treatment of infectious respiratory disease in cattle.Formal Name: 2,2-dichloro-N-[(1S,2R)-1-(fluoromethyl)-2-hydroxy-2-[4-(methylsulfonyl)phenyl]ethyl]-acetamide.
