The observation that 17-cyclopropylmethylmorphinan derivatives without the 4,5-epoxy ring showed more κ selectivity than those with a 4,5-epoxy ring led us to develop a working hypothesis: the position of the plane composed of the A and B rings would influence the opioid receptor type selectivity and that the decrease in the torsion angle C11–C12–C13–C14 could improve the κ selectivity. Consistent
没有4,5-环氧环的17-环丙基甲基吗啡喃衍生物比具有4,5-环氧环的衍生物具有更大的κ选择性,这使我们提出了一个可行的假设:由A和B环组成的平面的位置会影响阿片受体类型的选择性,扭转角C11–C12–C13–C14的减小可以改善κ选择性。与我们的假设一致,具有N-环丙基甲基丙炔结构的KNT-42 (其A和B环固定在大约0°的扭转角中)显示κ选择性激动剂活性。
