  Synthesis and evaluation of novel 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 as anxiolytics

  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.
