title: Anticonvulsant effect of denzimol in DBA/2 mice.
abstract: The anticonvulsant activity of N-[beta-[4-beta-phenylethyl)phenyl]-beta-hydroxyethyl]-imidazole hydrochloride, denzimol, was studied following intraperitoneal administration in DBA/2 mice (seizures induced by sound). Protection against sound-induced seizures was observed after intraperitoneal administration of denzimol (3-15 mg/kg). The ED50 values for the suppression of tonic, clonic and wild running phases of sound-induced seizures were 1.24, 2.61 and 6.03 mg/kg, respectively. This protective action was significantly reduced by pretreatment with aminophylline (25 mg/kg i.p.), CGS 8216 (1 or 5 mg/kg i.p.) and Ro 15-1788 (2.5 mg/kg i.p). The present experiments suggest an involvement of purinergic and benzodiazepine mechanisms in the anticonvulsant action of denzimol.
