pot heterogeneous synthesis of Δ3-THC from orcinol (1a) and pulegone (2). Four Δ3-THC analogues and corresponding Δ4a-tetrahydroxanthenes (Δ4a-THXs) were synthesized regioselectively and showed differential binding affinities for CB1 and CB2 cannabinoid receptors. Here we report for the first time the CB1 receptor binding of Δ3-THC, revealing a more potent receptor binding affinity for the (S)-(−) isomer
Δ 9 -四氢大麻酚(Δ 9 -THC)为大麻的主要的对精神的大麻素(大麻L.)和负责许多经由大麻素受体介导的药理学作用。尽管在本质上主要的大麻素支架,Δ 9 -THC双键异构体仍然研究甚少。四氢大麻酚的化学支架可以由明显取代的酚和单萜的缩合组装而成。在这里,我们探索了Δ的微波辅助一锅多相合成3从地衣酚(-THC 1A)和胡薄荷酮(2)。四Δ 3 -THC类似物和相应Δ 4a中-tetrahydroxanthenes(Δ 4A -THXs)的区域选择性合成并显示差的结合亲和力为CB 1和CB 2个大麻素受体。这里,我们报告首次CB 1 Δ的受体结合3 -THC,揭示了(更有效的受体结合亲和性小号) -异构体( - ()ħ CB 1 ķ我 比(= 5nm)的ř)-(+)异构体(h CB 1 K i = 29 nM)。像Δ 9 -THC,也Δ 3 -THC类似物是在CB受体部分激动剂所指示[35
