determined. These series are the (2'R)- and (2'S)-1-methoxy- and 1-deoxy-3-(2'-methylalkyl)-delta8-tetrahydrocannabinols, with alkyl side chains of three to seven carbon atoms. These compounds were prepared by a route that employed the enantioselective synthesis of the resorcinol precursors to the cannabinoid ring system. All of these compounds have greater affinity for the CB2 receptor than the CB1 receptor
制备了两个新系列的大麻素,并确定了它们对CB1和CB2受体的亲和力。这些系列是具有2至3个碳原子的烷基侧链的(2'R)-和(2'S)-1-甲氧基-和1-脱氧-3-(2'-甲基烷基)-delta8-四氢大麻酚。这些化合物是通过将间苯二酚前体对映异构合成至大麻素环系统的途径制备的。所有这些化合物对CB2受体的亲和力均高于CB1受体,其中四个(2'R)-1-甲氧基-3-(2'-甲基丁基)-δ8-THC(JWH-359),(2'S )-1-脱氧-3-(2'-甲基丁基)-δ8-THC(JWH-352),(2'S)-1-脱氧-3-(2'-甲基戊基)-δ8-THC(JWH-255), (2'R)-1-脱氧-3-(2'-甲基戊基)-delta8-THC(JWH-255),对CB2受体具有良好的亲和力(K(i)= 13-47 nM),对CB1受体具有极小的亲和力(K(i)= 1493至> 10,000 nM
