Enhanced binding of radioligands to receptors of gamma-aminobutyric acid and benzodiazepine by a new anticonvulsive agent, LY81067.


A diaryltriazine, LY81067, effectively protects against pentylenetetrazole- and picrotoxin-induced convulsions in mice, with ED50 values of 5.7 and 5.8 mg/kg i.p., respectively. LY81067 enhances the binding of both 3H-GABA and 3H-flunitrazepam to specific sites in rat brain membranes. The degree of enhancement by LY81067 varies from one brain region to… (More)
