Florfenicol is currently a commonly used veterinary antibiotic with a broad antibacterial spectrum and a strong antibacterial effect as well as a low the minimum inhibitory concentration (MIC). The antibacterial of florfenicol is about 15-20 times as high as that of chloramphenicol and the thiamphenicol. After administration through feed for 60 minutes, the drug concentration in the tissue can reach peak which can quickly control the disease with having characteristics such as being safe, non-toxic, no residue, and no risk for triggering aplastic anemia. Therefore, it is quite suitable for large-scale farms application. It is mainly used for the treatment of bovine respiratory disease caused by Pasteurella and Haemophilus. It has good efficacy in treating the cattle footrot disease cause by Fusobacterium, and can be also used for treating the infection diseases of pigs and chickens caused by sensitive strains as well as the bacterial disease of fish. structure.
Florfenicol is synthesised from thiamphenicol by replacing the 3-hydroxy group with fluorine, first synthesised at Schering in 1980. By replacing the hydroxy group, it was rationalised that chloramphenicol resistance via chloramphenicol acetyltransferase could be eliminated. Florfenicol is a broad spectrum antibiotic with good activity against Gram negative and anaerobic bacteria. Florfenicol acts by binding to the 23S sub-unit of the 50S ribosome, inhibiting protein synthesis. Florfenicol has been extensively studied with over 400 literature citations.
