Design, synthesis and antiepileptic properties of novel 1-(substituted benzylidene)-3-(1-(morpholino/piperidino methyl)-2,3-dioxoindolin-5-yl)urea derivatives
摘要:
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 50 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. (C) 2011 Elsevier Masson SAS. All rights reserved.

Anticonvulsant Activity of Novel 1-(Substituted Benzylidene)-4-(1-(Morpholino/Piperidino Methyl)-2,3-Dioxoindolin-5-yl) Semicarbazide Derivatives in Mice and Rats Acute Seizure Models
A series of novel 1‐(substituted benzylidene)‐4‐(1‐(morpholino/piperidino methyl)‐2,3‐dioxoindolin‐5‐yl) semicarbazides 6a–6t was designed and synthesized on the basis of semicarbazide‐based pharmacophoric model to meet the structural requirements necessary for anticonvulsant activity. The compounds were subjected to in vivo antiepileptic evaluation using maximal electroshock test and subcutaneous
