7,8,9,14-hexahydrodibenz[d,g]azecines are known to be potent dopamine receptor antagonists, whereas the corresponding rigid dibenzo[d,g]quinolizines are inactive. We built the scaffolds of dibenzo[c,g], [c,f] and [d,f]azecines and together with their ring closed, more rigid precursors, evaluated the affinities for the human D1–D5 receptors (radioligand binding) as well as the functionalities (calcium
的适度柔性的7-甲基5,6,7,8,9,14-hexahydrodibenz [ d,克]吖癸因已知是有效的多巴胺受体拮抗剂,而相应的刚性的二苯并[ d,克]喹嗪类是不活动的。我们构建了二苯并[ c,g ],[ c,f ]和[ d,f ] ze嗪的支架,并与它们的闭环,更刚性的前体一起,评估了对人D 1 –D 5的亲和力 受体(放射性配体结合)以及功能(钙测定),因此研究了这些化合物的脱嵌和构象柔韧性对其对人克隆的多巴胺受体的亲和力的影响。
