1,5-Diaryl-1H-1,2,4-triazole-3-carboxamide derivatives were designed, synthesized, and evaluated for its anticonvulsant activity using maximal electroshock (MES) and chemoshock (scPTZ and Strychnine) animal screen methods. Neurotoxicity was also assessed. In MES model, compound 4f showed 100% of phenytoin activity after both 0.5 and 4 h. In scPTZ model, compound 4e showed 100% of sodium valproate activity. In Strychnine model, compound 4e showed 120% more delay of onset of convulsion and 124% more delay of time of death relative to sodium valproate. Most of the target compounds showed mild neurotoxicity especially compound 4f which showed excellent activity against electroshock. Pharmacophoric study reveals that the synthesized compounds showed good fitting on the pharmacophoric query with good RMSDX results.
