Ceftiofur Usage And Synthesis
Brief introduction Ceftiofur is the veterinary-exclusive third-generation cephalosporins successfully developed by United States in the 1980s. It entered into market for the first time in the United States. Owing to their excellent antibacterial activity and pharmacokinetic characteristics, it has been officially approved by the United States, Canada, Japan and some European countries for being use in the treatment of respiratory therapy of beef cattle, dairy cattle, horses, pigs, and sheep. Its appearance is white to light yellow powder. It is insoluble in water, slightly soluble in acetone, and almost insoluble in ethanol.
Antibacterial activity Ceftiofur has a broad antimicrobial spectrum with strong antibacterial activity with strong antibacterial activity against Gram-positive and Gram-negative bacteria, and some anaerobic bacteria. Yancy RJ et al has studied the 264 pathogen strains from 17 kinds of veterinary clinical bacteria isolated from cattle, pigs, horses, poultry, dogs, and cats. Except S. aureus, the ceftiofur has a stronger antimicrobial activity than ampicillin against almost all strains (including strains production β-lactamase). Salmon S A et al has studied the antibacterial effect of ceftiofur and its major metabolite furan carbonyl ceftiofur on 539 veterinary clinical isolated pathogen strains and has shown that these two drugs has the same or similar antibacterial activity against Gram-negative bacteria.
