Abstract
Anticonvulsant activity of 7-phenyl-5H-thiazolo[5,4-e][1,2,3,4]tetrazolo[5,1-c]pyrrolo[1,2-a][1,4]diazepine (5) and 7-phenyl-5H-thiazolo[5,4-e][1,3,4]triazolo[5,1-c]pyrrolo[1,2-a][1,4]diazepines (6a-d) was measured against pentylenetetrazole (PTZ)-induced seizures in mice. Intraperitoneal injections of different doses (12.5, 25 and 50 mg/kg, i.p.) of test compounds decreased PTZ-induced seizure significantly in a dose-dependent manner.The test compounds were administered 30 min befor PTZ (80 mg/kg, i.p.) injection. The maximum response was obtained with 50 mg/kg of compound 6d that showed more anticonvulsant activity compared to diazepam (0.5 mg/kg). The frequency of mortality was also decreased by all listed compounds. Pretreatment of animals with flumazenile (as a benzodiazepine, BDZ receptor antagonist) decreased, but not completely inhibited the anticonvulsant activity of compound 6d (50 mg/kg). These results indicate that besides BZD receptors, other neurotransmitter systems may be involved in anticonvulsant activity of the tested compounds.
