Abstract
Five novel 2-[2[(pyridin-3-yl) phenyl] acetamides and ureas were designed based on a two-point pharmacophore, synthesized by improved methods, and screened for anticonvulsant activity in maximal electroshock seizure (MES) and ScPTZ-induced seizure models in Swiss mice at doses of 30, 100, and 300 mg/kg body weight. Compound 15 displayed potent anticonvulsant activity in MES test with ED50 value of 8.28 mg/kg and higher protective index (TD50/ED50 = 26) compared with Phenytoin, which can be considered as a promising lead.
