Biological Activity

Description Ceftiofur HCl (U-67279A,Excenel hydrochloride) is a cephalosporin antibiotic, used to treat both Gram-positive and Gram-negative bacteria infection.
In vitro
In vitro

Ceftiofur can downregulate tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), and interleukin-6 (IL-6), but did not affect interleukin-10 (IL-10) production. Ceftiofur significantly inhibits extracellular signal-regulated kinase (ERK), p38, and c-jun NH(2)-terminal kinase (JNK) phosphorylation protein expression in RAW 264.7 cells. Ceftiofur also inhibits p65-NF-kappaB translocation into the nucleus in RAW 264.7 cells. [1]

In vivo

Ceftiofur treatment is associated with a significant decrease in rectal temperature and diarrhea in neonatal calves. Ceftiofur results in a significant decrease in fecal shedding of Salmonella organisms in neonatal calves. [2] Ceftiofur hydrochloride (intrauterine (i.u.)) reduces the prevalence of positive uterineculture in cows with clinical endometritis (29.0 vs. 51.4%) and reduces the overall prevalence of Arcanobacterium pyogenes (1.0 vs. 7.6%) at 51 d in milk (DIM) . Ceftiofur hydrochloride reduces the prevalence of uterine infection in cows with clinical endometritis, and the prevalence of A. pyogenes, but does not affect the prevalence of subclinical endometritis or fertility of dairy cows already receiving PGF(2alpha). [3] Ceftiofur hydrochloride (i.m. injection) results in C(max) of 11.8 mg/mL at 1-4 hours after injection, the mean area under the curve (AUC) of 216 m g x h/mL in pigs. [4] Ceftiofur hydrochloride （2.2 mg of CE/kg, SC or IM, once daily for 5 days） is efficacious for treatment of acute postpartum metritis (APM) in dairy cows. [5]

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
