Eighteen 1-phenyl-, 1-thiocarbamoyland 1-N-substitutedthiocarbamoyl-3-phenyl-5-heteroaryl-2-pyrazoline derivatives were synthesized and tested for their antidepressant and anticonvulsant activities. Their chemical structures were proved by spectral and microanalysis. The antidepressant activities of the compounds were investigated by the "forced swimming test". Results showed that compounds II-a,b,c, III-1b,1c,4a showed activities equivalent to or higher than pargyline hydrochloride (CAS 306-07-0) and tranylcypromine sulfate (CAS 13492-01-8) that were used as reference antidepressant drugs. Anticonvulsant activities of the compounds were determined by maximal electroshock seizure (MES), subcutaneous metrazol (SeMet.) and rotarod toxicity tests in mice according to the phase I tests of the Andepileptic Drug Development programme. Compounds I-a, II-a,b,c, III-1b,2a,2c were found protective against MES and III-1b,1c,2a,2c were found protective against ScMet.
