synthesis of potential morphinomimetics as agonists of the human mu receptor. The well-known class of alkaloids represented by the isopavine nucleus has a topological resemblance to the morphine skeleton, especially when viewed in a particular way. Enantiopure isopavines can be readily obtained from a 1,2 Stevens rearrangement of 13-substituted dihydromethanodibenzoazocines, prepared in four steps from
视觉图像和关系思维的重要性在启发式方法中得到了体现,该方法用于设计和合成潜在的拟人拟物作为人类mu受体激动剂。以异戊烷核为代表的众所周知的生物碱类别与吗啡骨架具有相似的拓扑结构,尤其是在以特定方式观察时。对映体纯的异链烷可以很容易地从13个取代的D-和L-氨基酸的四个步骤制备的13-取代的二氢甲基二苯并偶氮恶唑的1,2 Stevens重排中获得。为了更好地与吗啡重叠,要考虑氮孤对的拓扑结构和预期取向,因此必须利用d-氨基酸。通过改变芳环上的取代基并明智地选择环取代基,可以获得与人mu受体的低纳摩尔结合,同时保持良好至优异的mu / delta选择性。在功能测定中针对最初衍生自d-丙氨酸的前体的类似物之一表明了激动剂样活性。几种化合物的X射线晶体结构证实了立体化学和整体拓扑。
