Twenty new 1-(substituted benzylidene)-3-(1-(morpholino/piperidino methyl)-2,3-dioxoindolin-5-yl) urea derivatives were designed and synthesized. Antiepileptic screening was performed using MES and scPTZ seizures tests. The neurotoxicity was determined by rotorod test. In the preliminary screening, compounds 5c, 5g, 5j and 5n were found active in MES model, while 5o showed significant antiepileptic activity in scPTZ model. Further all these five compounds were administered orally to rats, 5c, 5g and 5n showed better activity than Phenytoin in oral route. Among these compounds 5c revealed protection in MES at a dose of 30 mg/kg and 100 mg/kg 0.5 h and 4 h after i.p. administration respectively. This molecule provided also protection in the scPTZ at a dose of 300 mg/kg in both time intervals.

D004827 Epilepsy A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy).
