实验参考方法
In Vitro

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

In VivoCefoselis elicits a massive elevation of extracellular glutamate concentration in normal rats. 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.
