Abstract

Twenty-four compounds of 4-methoxy-N-[3-(4-substituted phenyl-piperazine-1-yl)propyl] benzene sulfonamides and N-[3-(4-substituted phenyl-piperazine-1-yl)propyl] naphthyl sulfonamides were prepared and evaluated as 5-HT(7) receptor antagonists. Most of the compounds showed the IC(50) values of 12-580nM. Four methyl branched analogues were also obtained, but the activity for methyl branched analogues was almost same as its straight chain congeners. Among the synthesized compounds, 3c showed a good activity on 5-HT(7) receptors and a good selectivity on 5-HT(1a), 5-HT(2a), 5-HT(2c), and 5-HT(6) receptors.
