A series of new 4,6-di(heteroaryl)pyrimidines containing an N-methylpiperazino group (6-13) or an ethylenediamine chain (15-20) in position 2 were synthesized and their 5-HT1A and 5-HT2A receptor affinities were determined. It was shown that the substituent effects on the 5-HT2A affinity are additive and could be described quantitatively. In a behavioral(More)
A series of 1,4-piperazine derivatives was synthesized and evaluated for anticonvulsant activity in the maximal electroshock seizure (MES) and subcutaneous pentylenetetrazole seizure threshold (ScMet) assays and for neurotoxicity (TOX). The compounds were only moderately effective. The anticonvulsant activity was accompanied by neurotoxicity.(More)
