6-Keto-hydroxymorphinans having at the 4 position a substituent which is R.sub.1 =H, O lower alkyl, or O lower acyl, and N may be substituted by R.sub.2, which for agonist properties may be lower alkyl, lower alkenyl, cyclopropylmethyl, or phenyl lower alkyl, etc. Additionally, the nitrogen may be substituted by R.sub.2, which is allyl, cyclopropylmethyl, cyclobutylmethyl, dimethylallyl, etc., which function as antagonists to the morphine-like activity of the compound. Such activity is known as antinociceptive.
在4位上具有取代基R.sub.1 = H、O较低烷基或O较低酰基的6-酮基羟吗啡类化合物,N可能被取代为R.sub.2,对于激动剂特性,R.sub.2可以是较低烷基、较低烯基、环丙基甲基或苯基较低烷基等。此外,氮原子也可以被R.sub.2取代,R.sub.2可以是烯丙基、环丙基甲基、环丁基甲基、二甲基烯丙基等,这些对化合物的类似吗啡活性起拮抗剂作用。这种活性被称为镇痛活性。
