A series of novel cannabinoid-type derivatives were synthesized by the coupling of (1S,4R)-(+) and (1R,4S)-(−)-fenchones with various resorcinols/phenols. The fenchone-resorcinol derivatives were fluorinated using Selectfluor and demethylated using sodium ethanethiolate in dimethylformamide (DMF). The absolute configurations of four compounds were determined by X-ray single crystal diffraction. The
通过 (1S,4R)-(+) 和 (1R,4S)-(-)-fenchones 与各种间苯二酚/苯酚的偶联合成了一系列新型大麻素类衍生物。使用 Selectfluor 将小茴香酮-间苯二酚衍生物氟化并使用乙硫醇钠在二甲基甲酰胺 (DMF) 中进行去甲基化。四种化合物的绝对构型由 X 射线单晶衍射测定。fenchone-间苯二酚类似物对 CB2 大麻素受体具有高亲和力和选择性。合成的类似物之一,2-(2',6'-dimethoxy-4'-(2"-methyloctan-2"-yl)phenyl)-1,3,3-trimethylbicyclo[2.2.1]heptan-2- ol (1d),对人 CB2 受体 (hCB2) 具有高亲和力 (Ki = 3.51 nM) 和选择性。在 [35S]GTPγS 结合试验中,我们的先导化合物被发现是一种高效的 hCB2 受体激动剂(EC50 = 2.59 nM,E(最大值)=
