Reputable factory supply Florfenicol 73231-34-2 in bulk at low price We provide high quality Florfenicol (CAS 73231-34-2), at a very affordable prices to our customers.
Florfenicol is a broad-spectrum fluorinated antibiotic and a derivative of thiamphenicol . 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.
Florfenicol can strongly interfere with the bacterial protein synthesis. It has a rapid absorption rate and is widely distributed in the body; it has long half-life without side effects such as aplastic anemia; not easy for bacteria to evolve drug resistance, and has no cross-resistance. Florfenicol can be used for the treatment of the systemic infection of livestock and aquatic animals, and has significant efficacy on treating respiratory infections and intestinal infections. Poultry: Escherichia coli disease, salmonellosis, infectious rhinitis, chronic respiratory disease, duck plague and other kinds of mixed infections caused by susceptible strains. Animals: Mixed infections such as infectious pleurisy, asthma, streptococcal disease, Escherichia coli disease, salmonellosis, contagious pleuropneumonia, enzootic pneumonia, paratyphoid piglets yellow white diarrhea, edema disease, atrophic rhinitis, lung epidemic, red white diarrhea piglets, and agalactia syndrome occurred in animals such as pigs, cows, and sheep. Crab: appendages ulcer disease, yellow gills, rotten gill, red legs and red fluorescent body inflammatory disease syndrome. Turtle: red neck disease, furunculosis, shot-hole disease, skin fester disease, inflammatory bowel disease, mumps, and bacterial sepsis. Frogs: cataract syndrome, ascites disease, sepsis, enteritis. Fish: enteritis disease, ascites disease, vibriosis, Edward coli disease. Eel: debonding septicemia (unique effect), Edward coli disease, red skin disease, inflammatory bowel disease.
Florfenicol is a fluorinated derivative of thiamphenicol. It is a protein synthesis inhibitor that inhibits bacterial protein synthesis by binding to ribosome 50S and 70S subunits. Florfenicol is used as an antibacterial.
The CAS number of Florfenicol is 73231-34-2.
