title: Selective group II glutamate metabotropic receptor agonist LY354740 attenuates pentetrazole- and picrotoxin-induced seizures.
abstract: There are several data indicating the involvement of metabotropic glutamate receptors (mGluR) in seizures and epileptogenesis. In the present experiments, the selective group II mGluR agonist (+)-2-aminobicyclo-[3.1.0]hexane-2,6-dicarboxylic acid (LY 354740) at doses from 4 to 16 mg/kg) administered prior to the injection of pentetrazole (80 mg/kg) or picrotoxin (3.2 mg/kg) produced a dose-dependent decrease in the number of mice exhibiting clonic convulsions. Our data suggest that group II mGluR agonist LY 354740 possesses antiseizure activity.
