I do appreciate that this is a very specific question but I am faced with the situation in which the only published work on a specific class of drug (14-methoxy morphinans) seems to have been carried out by Japanese researchers and with the best will in the world, even if I spend years assiduously studying Japanese, it's unlikely that I would be able to read a technical paper.
I'm not entirely certain that the compound I'm researching is even covered by the patent application I have found BUT I cannot discount the possibility. PubChem does reference the patent, but I'm not sure if THEY are mistaken.
Long story short. In the 70s Bristol-Myers developed the analgesic butorphanol. But they were VERY careful not to cover any analogues that may have been pure agonists. I mean, they avoided mentioning the N-methyl analogue which is almost universally used as a metric with which to measure analogues.
I'm even unable to identify the authors so I'm uncertain if any English-language papers exist.
It's at times like this that I realize just how ignorant I truly am.
Many thanks.
