A series of 3- and 5-aryl-1,2,4-oxadiazole derivatives were prepared and tested for anticonvulsant activity in a variety of models. These 1,2,4oxadiazoles exhibit considerable activity in both pentylenetetrazole (PTZ) and maximal electroshock seizure (MES) models. Compound 10 was protective in the PTZ model in rats with an oral ED50 of 25.5 mg/kg and in the MES model in rats with an oral ED50 Of 14.6 mg/kg. Neurotoxicity (rotarod) was observed with an ED50 Of 335 mg/kg. We found several oxadiazoles that acted as selective GABA potentiating compounds with no interaction to the benzodiazepine binding site. (c) 2007 Elsevier Masson SAS. All rights reserved.
