Some new N-substituted alpha-aryl/alkyl succinimides as possible anticonvulsants.

In view of their expected MAO inhibitory CNS depressant and anticonvulsant properties a number of N-(5-alkyl-1,3,4-thiadiazol-2-yl)-alpha-aryl/alkyl succinimides (1-20) and N-(cyclohexyl)-alpha-aryl/alkyl succinimides (21-25) have been synthesized. Some of them when screened for anticonvulsant activity against pentetrazole induced seizures in mice at a dose of 80 mg/kg were found to be 10 to 50% active.
