title: Synthesis and anticonvulsant activity of some new hexahydropyrimidine-2,4-dione derivatives.
abstract: In this study, twelve new hexahydropyrimidine-2,4-dione derivatives were synthesized and screened for their anticonvulsant activities. All the compounds (7a-1) which have 6-arylhexahydropyrimidine-2,4-dione and N,N-disubstituted dithiocarbamate structures were prepared by the reaction with appropriate 3-(2-chloroethyl)-6-arylhexahydropyrimidine-2,4diones and the corresponding N,N-disubstituted dithiocarbamate potassium salts. The structure of the synthesized compounds was confirmed by UV, IR, 1H-NMR and elemental analysis. Their anticonvulsant activities were determined by maximal electroshock (MES), subcutaneous pentetrazol (metrazol, scMet) and rotorod toxicity tests for neurological deficits. According to the activity studies, 6-(4-chlorophenyl)hexahydropyrimidine-2,4-dione derivatives (7e-h) were found to be highly protective against MES and scMet. Neurotoxicity was not observed in any of the tested compounds.
