A congener of methadone, in which the metabolically labile C-6 dimethylamino moiety was replaced with a piperidinospiro derivative, was reduced and acetylated. This conversion produced a marked increase in the duration of analgesia, a trend similar to that found for methadone.
美沙酮的一种同系物,其中代谢不稳定的C-6二甲基氨基部分被哌啶螺衍生物取代,经还原和乙酰化处理。这种转化使镇痛持续时间显著增加,这一趋势与美沙酮相似。
