in vitro evaluation of benzo-fused benzodiazepines 1-6 are described. These "molecular yardsticks" were employed to probe the spatial dimensions of the lipophilic pocket L2 in the benzodiazepine receptor (BzR) cleft and to determine the effect of occupation of L2 with respect to agonist activity. Of the new analogs synthesized, the 7,8-benzo-fused benzodiazepine 6 displayed moderately high affinity
描述了苯并稠合的苯并二氮杂1-6的合成和体外评估。这些“分子尺度”用于探查苯并二氮杂receptor受体(BzR)裂口中亲脂性口袋L2的空间尺寸,并确定L2占用对激动剂活性的影响。在合成的新类似物中,7,8-苯并稠合的苯并二氮杂6 6对BzR表现出中等程度的亲和力(IC50 = 55 nM),并同时显示抗惊厥药(ED50约15 mg / kg)和肌肉松弛剂(ED50约15 mg / kg)。 kg)活动。如预期的那样,2和4与相互作用的排斥区S1和S2相互作用,并且对BzR表现出低亲和力。这些分子尺度的刚性(尤其是图7中的6)已被用来探测L2的深度。此外,
