The synthesis and pharmacological evaluation of a series of pyrazolo[b][1,5]benzodiazepines are described. Some of the 4-piperazinyl-2,10-dihydropyrazolo[3,4-b][1,5]benzodiazepine derivatives demonstrated potent anxiolytic activity in the three-part operant anticonflict test in rats. Compounds 21 and 30 were more active than the clinically effective anxiolytic chlordiazepoxide in releasing conflict-suppressed
描述了一系列吡唑并[b] [1,5]苯并二氮杂s的合成和药理学评价。在大鼠的三部分操作性抗冲突试验中,一些4-哌嗪基-2,10-二氢吡唑并[3,4-b] [1,5]苯并二氮杂卓衍生物具有较强的抗焦虑活性。化合物21和30在释放冲突抑制行为方面比临床上有效的抗焦虑药氯氮卓更具活性。这项研究表明,分别在噻吩和二苯并二氮杂卓衍生物氟美沙平和氯氮平中发现的抗焦虑和抗多巴胺能活性已解离。描述并评估了其他三个其他二氢吡唑并[b] [1,5]苯并二氮杂ring环系统的实例,发现它们的活性较低。
