variety of derivatives synthesized, only the 7-chloro compound 1b showed receptor affinity comparable to 1a with slightly improved in vivo activity. The poor correlation between receptor binding and in vivo activity may be due to variability in absorption or pharmacological responses unrelated to affinity for the benzodiazepine receptor.
制备了一系列的氧代吡咯并苯并噻嗪(氮杂吩噻嗪),并评估了其与苯并二氮杂in受体的结合,戊戊四唑诱发的抽搐试验中的抗惊厥活性,以及在两种情况下,通过标准冲突试验提高了惩罚能力。尽管母体化合物1a的结合亲和力可与氯二氮杂卓(CDP)媲美,但其在抗惊厥试验和抗冲突试验中的功效比CDP弱得多。在合成的各种衍生物中,只有7-氯化合物1b的受体亲和力与1a相当,体内活性略有改善。受体结合与体内活性之间的不良相关性可能归因于与苯二氮卓受体亲和力无关的吸收或药理反应差异。
