The bimorphinans 6 and 7 have been prepared from 14-O-methylnaloxone (2) and 14-O-methylnaltrexone (3), respectively. The known compounds 2 and 3 were synthesized by a different route than the route described. Bimorphinan 7 possessed a similar χ receptor affinity to norbinaltorphimine (1) but had a reduced selectivity due to marked increases in μ and δ receptor affinity. Bimorphinan 6 was both a less
双
吗啡喃6和7分别由14 - O-
甲基纳洛酮(2)和14- O-
甲基纳曲酮(3)制备。已知化合物2和3是通过与所述途径不同的途径合成的。双
吗啡喃7具有与norbinaltorphimine(1)相似的χ受体亲和力,但由于μ和δ受体亲和力显着增加,选择性降低。双
吗啡喃6的选择性和活性均低于1。
