咪唑并[2,1- b ]噻唑,咪唑并[ 2,1- b ]咪唑和吡咯并[1,2- c ]咪唑。苯二氮杂receptor受体结合的合成,结构及评价
摘要:
作为我们对具有苯并二氮杂receptor受体亲和力的双环杂环的研究的延续,具有5:5双环骨架的衍生物,即咪唑并[2,1- b ]噻唑,咪唑并[2,1- b ]咪唑和吡咯并[1,2-制备了c ]咪唑。这些化合物具有芳族取代基,该芳族取代基具有不同的空间排列和距双环骨架的距离。对Z-2-(4-氯亚苄基)-5,5-二苯基-2,3,5,6-四氢咪唑并[2,1 - b ]咪唑啉-3,6-二酮(6a)进行了X射线结构分析和5-氨基-6-氰基-7-苯基-1-氧代-3-硫代氧-2,3-二氢-1 H-吡咯并[1,2- c ]咪唑(20a)。与先前描述的芳基亚二唑并[2,1- b ]噻嗪酮相反,该研究中研究的较小的杂环体系缺乏有意义的苯并二氮杂receptor受体亲和力和抗惊厥活性。

of our search for new ligands acting on benzodiazepinereceptors among the fused 2-thiohydantoin derivatives, a series of 5-substituted imidazo[2,1-b]thiazepines was synthesized and investigated in radioligand binding studies at the benzodiazepinebinding site of GABA(A) receptors in rat brain cortical membranes. Among ortho-substituted 5-arylidene-imidazo[2,1-b]thiazepines compounds could be identified
