  摘要：

  A series of 2-aryl-2,5,6,7-tetrahydro-3H-thieno[2',3':6,7]cyclohepta[1,2-c]pyridazin-3-ones and 2-aryl-5,6-dihydrothieno[2,3-h]cinnolin-3(2H)-ones were synthesized and evaluated for their affinity to benzodiazepine receptors (BZRs) in the excised brain of rats and also for their intrinsic efficacy in augmentation of the gamma-aminobutyric acid-induced chloride currents in the dissociated sensory neurons of frogs. The synthesized compounds showed a high affinity to BZRs. In these compounds, the substituents at the 2-position and at either the 8- or the 9-position and the ring size of the condensed ring affected the biological activity of the compounds. Thus, an introduction of 4-methyl- or 4-chloro-substitute phenyl ring into the 2-position, an introduction of methyl or ethyl into either the 8- or the 9-position, and an expansion of the 6-membered condensed ring to a 7-membered ring brought about a continuous shift of compounds from inverse to full agonists. Among the synthesized compounds, 8-(1 hydroxyethyl)-2-(4-methylphenyl)-5,6-dihydrothieno[2,3-h]cinnolin-3(2H)-one which can be classified as a BZR partial agonist, was found to exhibit an anxio-selective feature.

  Starting from benzo- or thienocycloalkaneacetic acids, we have prepared a series of 1-(3-p-fluorobenzoylpropyl)-4-(1-oxo-benzo- or thienocycloalkyl-2-ethyl)piperazines 8a-e containing both semirigid and linear butyrophenones pharmacophores. The affinities of these compounds for dopamine (D2) and 5-hydroxytryptamine (5-HT2A) receptors were evaluated in vitro in receptor-binding assays and in functional experiments. The ratios of pKi's for 5-HT2A/D2 receptors may be useful for rapid screening of new compounds and assessing potential induction of extrapyramidal symptoms; ratio values ≥-1.12 (Meltzer's ratio) are predictive of an atypical antipsychotic profile. The new molecules had a ratio in the range of 0.96-1.11 while haloperidol showed a ratio of 0.93. The 2-piperazinoethyl thiotetralone derivative 8d (QF 0506B) with a ratio of 1.11 was the most active compund.

  A series of 52 conformationally constrained butyrophenones have been synthesized and pharmacologically tested as antagonists at 5-HT2A, 5-HT2B, and 5-HT2C serotonin receptors, useful for dissecting the role of each 5-HT2 subtype in pathophysiology. These compounds were also a consistent set for the identification of structural features relevant to receptor recognition and subtype discrimination. Six compounds were found highly active (pK(1) > 8.76) and selective at the 5-HT2A receptor vs 5-HT2B and/or 5-HT2C receptors. Piperidine fragments confer high affinity at the 5-HT2A receptor subtype, with benzofuranone- and thiotetralonepiperidine as the most selective derivatives over 5-HT2C and 5-HT2B receptors, respectively; K-1 2A/2C and/or K-B 2A/2B ratios greater than 100 were obtained. Compounds showing a more pronounced selectivity at 5-HT2A/5-HT2C than at 5-HT2A/5-HT2B bear 6-fluorobenzisoxazolyl- and p-fluorobenzoylpiperidine moieties containing one methylene bridging the basic piperidine, to the alkanone moiety. An ethylene bridge between the alkanone and the amino moieties led to ligands with higher affinities for the 5-HT2B receptor. Significant selectivity at the 5-HT2B receptor vs 5-HT2C was observed with 1-1[(1-oxo-1,2,3,4-tetrahydro-3-naphthyl)methyl-4-[3-(p-fluorobenzoyl)propyl]piperazine (more than 100-fold higher). Although piperidine fragments also confer higher affinity at 5-HT2C receptors, only piperazine-containing ligands were selective over 5-HT2A. Moderate selectivity was observed at 5-HT2C vs 5-HT2B (10-fold) with some compounds bearing a 4-[3-(6-fluorobenzisoxazolyl)]piperidine moiety in its structure. Molecular determinants for antagonists acting at 5-HT2A receptors were identified by 3D-QSAR (GRID-GOLPE) studies. Docking simulations at 5-HT2A and 5-HT2C receptors suggest a binding site for the studied type of antagonists (between transmembrane helices 2, 3, and 7) different to that of the natural agonist serotonin (between 3, 5, and 6).
