title: Design, synthesis and pharmacological screening of potential anticonvulsant agents using hybrid approach.
abstract: A series of 9H, 10H, 3-[N- 4 methyl -2-benzamido thiophen 3-yl carbonyl amino [2-(2'-phenyl 1'- ethylenyl)] 10-(aryl) thiazolidino [4, 5-b] 1, 5 benzodiazepine [7a-7h] were designed and synthesized to meet the structural requirements essential for anticonvulsant activity. Anticonvulsant activity was determined after intra-peritoneal administration to mice by supramaximal electroshock seizures model and Isoniazide Hydrazone induced seizures model. Motor impairement was determined using actophotometer and rotarod apparatus. Among the synthesized compounds two [JG 7a and JG 7e] compounds exhibited significant anticonvulsant activity after intra-peritoneal administration. Active compounds carry hydroxy substitutent at 2-position and methoxy at 4-position in the phenyl ring at C(5) of benzodiazepine. In present we study conclude that small polar and electron rich groups contribute significantly for anticonvulsant activity while electronegative substitutents showed lesser contribution for anticonvulsant activity.
