  Synthesis and pharmacology of (R)- and (5)-4′-hydroxy-Δ9-tetrahydrocannabinols

  摘要：

  The (R)- and (S)-4'-hydroxy-Delta(9)-tetrahydrocannabinols 1a,b (tetrahydrocannabinol = THC) were synthesized by the condensation of (+)-cis-p-menth-2-ene-1,8-diol 3 with the corresponding (R)- and (S)-4'-acetoxy olivetols 4a,b, followed by base hydrolysis. The optical purity of 1a,b was estimated to be >87% ee. Pharmacological data presented here indicate that 1a is two to three times more potent than 1b in vivo (locomotion, antinociception and catalepsy measures) and eight times more potent in its affinity for the cannabinoid CB1 receptor. Additionally, data from catalepsy and hypothermia measures at both the normal and short time-course evaluations indicate that both isomers possess a short duration of action which is presumably due to rapid metabolism. A comparison of the biological activity of 3'- and 4'-hydroxy-Delta(9)-THCs indicates that although similar specificity resides in both the 3'- and 4'-positions, the 3'-position is more important than the 4'-position since (S)-3'-hydroxy-Delta(9)-THC is much more potent than (R)-4'-hydroxy-Delta(9)-THC. Furthermore 1b has an indication of a lead for separation of hypothermic effects from other pharmacological activities.

  摘要：

  本研究描述了从 3,5-二羟基苯甲酸（4）合成四氢大麻酚衍生物的关键中间体 (R)- 和 (S)-4′-acetoxyolivetols 的合成过程。3,5-二羟基作为其叔丁基二甲基硅烷衍生物受到保护，苯甲酸基则转化为苄基-1,3-二噻烷衍生物 8。 将 8 的阴离子与手性 1,2-环氧丙烷处理后得到二噻烷醇 9，经过乙酰化、脱硫和酚羟基脱保护后，得到所需的 4′-乙酰氧基橄榄醇 (2a,b)，总产率为 13%。
