that many sigma ligands have been designed from known sigma ligands. We focused on a difference in structural flexibility between haloperidol and apomorphine, and studied chemical modification of apomorphine, a compound with high affinity for dopamine D2 receptors but not for sigma receptors, for discovery of sigma ligands. The first modification yielded good results with 6H-dibenzo[b,d]pyran analogues
似乎已经从已知的sigma配体设计了许多sigma配体。我们着眼于氟哌啶醇和阿扑吗啡之间结构柔性的差异,并研究了阿扑吗啡的化学修饰,该化合物对多巴胺D2受体具有高亲和力但对sigma受体没有高亲和力,以发现sigma配体。第一种修饰对6H-二苯并[b,d]吡喃类似物的合成具有良好的效果,其对sigma受体的亲和力较弱,但对D2受体的亲和力较弱。此外,咔唑类似物(由6H-二苯并[b,d] pyran类似物设计的化合物)可能以高选择性作用于sigma受体。本文介绍了6H-二苯并[b,d]吡喃和咔唑类似物的设计,合成和sigma / D2选择性。
