Biological Activity

Description Cefoselis (FK 037 Sulfate) is a widely used beta-lactam antibiotic.
In vitro
In vitro

Cefoselis inhibits GABA-induced currents in a concentration-dependent manner with IC50 of 185 mM. [1] Cefoselis possesses a superior antistaphylococcal activity on MSSA isolates to both other compounds being however equal active to Cefepime and Cefpirome on multiresistant enterobacteriaceae. [2] Cefoselis is dose-dependently appeared in brain extracellular fluid in proportion to its blood level. [3] Cefoselis, a new parenteral cephalosporin, is active against clinical isolates of both gram-positive and gram-negative aerobic bacteria. [4]
In Vivo
In vivo

Cefoselis elicits a massive elevation of extracellular glutamate concentration in normal rats. [3] Cefoselis (50 mg/animal)-induced convulsions are prevented by pretreatment with 5-methyl-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5,10-imine (MK-801), diazepam and phenobarbital (ED(50) values (mg/kg) of 0.78, 1.59 and 33.0, respectively), but not by carbamazepine or phenytoin.

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.
