The orvinols are a class of potent opioids which have been extensively studied, yet little is known about the effects of introducing substituents into the 18- and 19-positions. The etheno bridge of thevinone was hydroxylated to give both the 18- and 19-hydroxyl substituted thevinols. After 3-O-demethylation to the corresponding orvinols, binding and GTPgammaS functional assays indicated that hydroxyl substitution at the 18- and 19-positions differentially affects the mu opioid efficacy of orvinols.
奥维诺醇类是一类经过广泛研究的强效阿片类药物,但对于在18位和19位引入取代基的影响却知之甚少。将蒂巴因酮的乙烯桥羟基化,得到18位和19位羟基取代的奥维诺醇。在将其3-O-去甲基化转化为相应的奥维诺醇后,结合和GTPγS功能测定表明,18位和19位的羟基取代对奥维诺醇的μ阿片样物质效能有不同影响。
