• Synthesis and serotonergic activity of variously substituted (3-amido)phenylpiperazine derivatives and benzothiophene-4-piperazine derivatives: novel antagonists for the vascular 5-HT1B receptor

  日期：2004.4

  The synthesis and vascular 5-HT1B receptor activity of a novel series of substituted 3-amido phenylpiperazine and 4-(4-methyl-1-piperazinyl)-1-benzo[b]thiophene derivatives is described. Modifications to the amido linked sidechains of the 3-amidophenyl-piperazine derivatives and to the 2-sidechain of the 1-benzo[b]thiophene derivatives have been explored. Several compounds were identified which exhibited affinity at the vascular 5-HT1B receptor of pK(B) > 7.0. From the 3-aminophenyl-piperazine series, N-(4-(4-chlorophenyl)thiazol-2-yl-3-(4-methyl-1-piperazinyl)benzamide (30) and from the benzo[b]thiophene-4-piperazine series N-(2-ethylphenyl)-4-(4-methyl-1-piperazinyl)-1-benzo[b]thiophene-2-carboxamide (38) were identified as a highly potent, silent (as judged by the inability of angiotensin II to unmask 5-HT1B receptor mediated agonist activity in the rabbit femoral artery) and competitive vascular 5-HT1B receptor antagonist. The affinity of compounds from these two series of compounds for the vascular 5-HT1B receptor is discussed as well as a proposed mode of binding to the receptor pharmacophore. (C) 2004 Elsevier SAS.
