these analogs revealed several structural features that were important for maintaining CB(1) receptor recognition and in vivo activity, including the presence of a branched lipophilic side chain and free phenols as well as substitution of a cyclohexane as the second ring of these bicyclic cannabinoids. Many of these analogs exhibited CB(2) selectivity, particularly the dimethoxyresorcinol analogs, and
尚不十分了解Delta(9)-四氢大麻酚的苯并吡喃取代基的氧在定义对脑大麻素(CB(1))受体的亲和力中的作用;然而,众所周知,打开吡喃环会导致效力和亲和力的提高,如CP 55940 [[-)-顺-3- [2-羟基-4(1,1-二甲基庚基)苯基]-反式-4-(3-羟基-丙基)环己醇]或在非活性大麻素中(如大麻二酚)。在本研究中,合成了一系列类似于大麻二酚的双环间苯二酚,并在体外和体内进行了测试。对这些类似物的结构-活性关系的分析显示了几个结构特征,这些特征对于维持CB(1)受体的识别和体内活性非常重要,包括存在分支的亲脂性侧链和游离酚,以及取代环己烷作为这些双环大麻素的第二个环。这些类似物中的许多表现出CB(2)选择性,特别是二甲氧基间苯二酚类似物,并且更长的侧链长度增强了这种选择性。因此,与大麻二酚不同,这些间苯二酚衍生物具有对CB(1)和/或CB(2)受体的良好亲和力以及强大的体内活性
