The cannabinoid side chain is a key pharmacophore in the interaction of cannabinoids with their receptors (CB1 and CB2). To study the stereochemical requirements of the side chain, we synthesized a series of cannabinoids in which rotation around the C1'-C2' bond is blocked. The key steps in the synthesis were the cuprate addition of a substituted resorcinol to (+)-apoverbenone, the TMSOTf-mediated
大麻素侧链是大麻素与其受体(CB1和CB2)相互作用的关键药效团。为了研究侧链的立体化学要求,我们合成了一系列大麻素,其中围绕C1'-C2'键的旋转被阻止。合成中的关键步骤是向(+)-apoverbenone取代的间苯二酚进行铜酸盐的加成,TMSOTf介导的二氢吡喃环的形成以及β-11-羟甲基的立体定向引入。所有测试的类似物均显示出对受体的纳摩尔亲和力,其中顺式-庚-1-烯侧链对CB1的亲和力最高(Ki = 0.89 nM),并且在CB1和CB2亲和力之间的分离范围最广。母体正庚基-β-11-羟基六氢大麻酚与CB1的结合力最低(Ki = 8。
