displayed moderate binding affinity and selectivity at the μ receptor, with compound 7b showing the highest affinity at this receptor with a Ki value of 40 nM, and 6- and 25-fold selectivity against δ and κ receptors, respectively. Function assays showed that indolopropellanes 7b and 7c possessed full agonistic activity at all the opioid receptors indicating a different interaction model existed.
通过3-甲氧基-N-甲基-14-羟基吗啡喃-6-one 12的N-去甲基化,然后进行N-重烷基化,还原和Fischer吲哚环化,获得了一系列骨架重排的吲哚吗啡喃7a-d。通过X射线分析证实了该新型骨架的结构。这些新的吲哚在μ受体上表现出中等的结合亲和力和选择性,化合物7b在该受体上显示出最高亲和力,其K i值为40 nM,对δ和κ受体的选择性分别为6倍和25倍。功能测定表明吲哚丙二酮7b和7c 在所有阿片样物质受体上都具有完全激动作用,表明存在不同的相互作用模型。
