title: Anticonvulsant properties of N-(4-methylpiperazin-1-yl)- and N-[3-(4-methyl-piperazin-1-yl)propyl] derivatives of 3-aryl- and 3-spirocycloalkyl-pyrrolidine-2,5-dione.
abstract: Two series of N-(4-methylpiperazin-1-yl)- and N-[3-(4-methylpiperazin-1-yl)-propyl]-3-aryl- and 3-spirocycloalkyl-pyrrolidine-2,5-dione derivatives were synthesized and tested for anticonvulsant activity in the maximum electroshock (MES) seizure and pentetrazole (sc PTZ) seizure threshold tests. Compounds with an aromatic ring at position-3 of pyrrolidine-2,5-dione exhibited anticonvulsant activity in the MES test. For that series of compounds, ED50 values were determined. The most potent in the series were derivatives and with a chlorine atom at position-3 or 4 of the aromatic ring. Those compounds exhibited strong anticonvulsant activity, and their ED50 values ranged from 29 to 48 mg/kg. Introduction of the spirocycloalkyl ring into the position-3 of pyrrolidine-2,5-dione made those compounds inactive.
