  Triazolobenzo- and triazolothienodiazepines as potent antagonists of platelet activating factor

  摘要：

  A series of [1,2,4]triazolo[4,3-alpha][1,4]benzodiazepines bearing an ethynyl functionality at the 8-position and the isosteric thieno[3,2-f][1,2,4]triazolo[4,3-alpha][1,4]diazepines were prepared and evaluated as antagonists of platelet activating factor. The effects of substitution were explored in in vitro and in vivo test systems designed to measured PAF-antagonistic activity. Results are discussed and compared with previously published data. Many of the compounds had activity superior to WEB 2086, compound 1. In general, the thieno analogues exhibited better oral activity than the corresponding benzodiazepines. The duration of activity upon oral administration was modulated by the substitution on the acetylenic side chain. Compounds 71 and 81 were selected for further pharmacological evaluation as a result of their good oral potency and exceptionally long duration of action.

  Ketanserin类似物：5-HT2和5-HT1C血清素受体结合的结构亲和性关系。

  摘要：

  酮色林是原型5-HT2血清素拮抗剂。尽管它一直是研究5-羟色胺药理学的重要工具，但它对药物设计的影响相对较小，因为对其结构亲和性关系知之甚少。此外，酮色林还与5-HT1C受体结合，对其结构特征对5-HT1C受体亲和力的影响知之甚少。本研究表明，酮色林的4-氟苯甲酰基部分的氟和羰基对5​​-HT2结合的贡献很小，完整的苯甲酰基哌啶部分是重要的特征。哌啶环的开环降低了亲和力。尽管喹唑啉-2,4-二酮部分也有助于结合，它似乎起着较小的作用，并且可以通过保留5-HT2亲和力在结构上简化。例如，N-（4-苯基丁基）-4-（4-氟苯甲酰基）哌啶（39）以与酮色林（Ki = 3.5 nM）几乎相同的亲和力（Ki = 5.3 nM）结合。所有检测到的化合物在5-HT1C位点的结合亲和力均比酮色林低，某些简化的类似物以5-HT2C结合酮色林的5-HT1C选择性结合近十倍。但是，没有显示> 120倍的选择性。

  prototypic 5-HT2 serotonin antagonist; although it has been an important tool for the study of serotonin pharmacology, it has had relatively little impact on drug design because remarkably little is known about its structure-affinity relationships. Furthermore, ketanserin also binds at 5-HT1C receptors and even less is known about the influence of its structural features on 5-HT1C receptor affinity. The present
