Product name:Cefquinome
Product description:Cefquinome is a fourth generation cephalosporin with pharmacological and antibacterial properties valuable in the treatment of coliform mastitis and other infections. It is only used in veterinary applications.
Cefquinome is resistant to beta-lactamase. Chemically, its zwitterionic structure can facilitate rapid penetration across biological membranes, including porins of bacterial cell wall. Plus, it has a higher affinity to target penicillin binding proteins. The reactive site is a beta-lactam nucleus, while the main peripheral functional groups are a quaternary quinolinium, an aminothiazolyl moiety and an unusual O-alkylated oxime.
Cefquinome acts by inhibition of the cell wall synthesis, but it has a relatively short half-life of about two and half hours. It is less than 5% protein bound and is excreted unchanged in the urine.
