search for potent ligands at the benzodiazepine site on the GABAA receptor, new fluoro derivatives of the pyrazolo[5,1-c][1,2,4]benzotriazine system were synthesized to evaluate the importance of the introduction of a fluorine atom in this system. Biological and pharmacological studies indicate that the substitution at position 8 with a trifluoromethyl group confers pharmacological activity due to potential
在寻找GABA A受体的苯并二氮杂site位点的有效配体时,合成了吡唑并[5,1- c ] [1,2,4]苯并三嗪系统的新含氟衍生物,以评估引入氟的重要性这个系统中的原子。生物学和药理研究表明,与无活性的8-甲基取代类似物相比,由于其潜在的代谢稳定性,在8位被三氟甲基取代的化合物具有药理活性。特别是化合物3-(2-甲氧基苄氧基羰基)-8-三氟甲基吡唑并[5,1- c ] [1,2,4]苯并三嗪5-氧化物(21)的出现是由于其选择性的抗焦虑作用而没有副作用。对我们药效图中所有新合成的化合物的分析证实了结合识别所必需的相互作用点以及亲和力调节的重要区域。仅当氟原子不在位置3时,它才能形成氢键相互作用。
