Cefquinome
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. Properties Cefquinome is resistant to beta-lactamase. Chemically, its zwitterionic structure can facilitate rapid penetration across biological membranes, including porins of bacterial cell walls. 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 2.5 hours. It is less than 5% protein bound and is excreted unchanged in the urine.Intervet, "Cephaguard Injection Data Sheet," Studies Many studies have been conducted, mostly for animal use.
