of our unexpected finding that opioid antagonists can be obtained in the 5-phenylmorphan series of opioids without sterically hindering the rotation of the phenolic ring. We determined the opioid receptor binding affinity of these new analogues, as well as the efficacy of the more interesting ligands. One of the new compounds [(1R,5S)-(-)-3-[2-(3'-phenylpropyl)-2-azabicyclo[3.3.1]non-5-yl]-phenol,
合成和评估了5-(3-羟苯基)吗啡配体的对映异构体,因为我们出乎意料地发现,可以在5-苯基吗啡系列阿片类药物中获得阿片类拮抗剂,而不会在空间上阻碍酚环的旋转。我们确定了这些新类似物的阿片受体结合亲和力,以及更有趣的配体的功效。发现一种新化合物[(1R,5S)-(-)-3- [2-(3'-苯丙基)-2-氮杂双环[3.3.1]壬-5-基]-苯酚,15]在[(35)S] GTPgammaS分析中,纳洛酮(一种有效的阿片类药物拮抗剂)的功效只有一半,而另外两种(1R,5S)-(-)-3- [2-(4'-苯基丁基)-2 -氮杂双环[3.3.1]非-5-基]-苯酚,17和(1R,5S,1'S)-(+)-3- [2-(1'-甲基-2'-苯乙基)-2-氮杂双环[3.3.1] non-5-yl]-苯酚,26,充当中度有效的阿片类药物拮抗剂。获得了三种化合物的X射线晶体结构数据。其中两个有三个手性中心。25 [(1R,5S,1'R)-(-)-3-
