  摘要：

  A new series of 3-, 7- and 8-substituted pyrazolo[5,1-c][1,2,4]benzotriazine 5-oxides and a series of pyrazolo[5,1-c][1,2,4]benzotriazines were synthesized and their benzodiazepine receptor affinities were evaluated in vitro. A study of structure-affinity relationships within the series is briefly discussed, considering the role of various substituents at the 3-, 7- and 8-positions and the role of N-5-oxide. Compounds 1b, 1c, 1cR, 4c, 4cR, 9d, 12d and 12dR were evaluated in vivo for their anticonvulsant effects.

  The synthesis and the binding study of new 3-arylesters and 3-heteroarylpyrazolo[5,1-c][1,2,4]benzotriazine 5-oxide 8-substituted are reported. The nature of these substituents (in terms of lipophilic and electronic features) seems to influence the binding affinity. High-affinity ligands were studied in mice in vivo for their pharmacological effects, considering six potential benzodiazepine actions:

  报道了新的3-芳基酯和3-杂芳基吡唑并[5,1-c] [1,2,4]苯并三嗪5-氧化物8-取代的合成和结合研究。这些取代基的性质（就亲脂性和电子特性而言）似乎会影响结合亲和力。研究了体内高亲和力配体的药理作用，其中考虑了六种潜在的苯二氮卓类作用：抗焦虑作用，肌肉松弛作用，运动协调，抗惊厥作用，自发运动和乙醇增强作用。化合物4d和6d显示出反向激动剂特征。还评估了这些化合物在GABAA受体复合物（GABAA / BzR复合物）亚型上苯并二氮杂位处的结合，以评估其亚型选择性。
