  Structure–activity relationships for 1′,1′-dimethylalkyl-Δ 8 -tetrahydrocannabinols

  摘要：

  A series of 1',1'-dimethylalkyl-Delta(8)-tetrahydrocannabinol analogues with C-3 side chains of 2-12 carbon atoms has been synthesized and their in vitro and in vivo pharmacology has been evaluated. The lowest member of the series, 1',1'-dimethylethyl-Delta(8)-THC (8, n = 0) has good affinity for the CB1 receptor, but is inactive in vivo. The dimethylpropyl (8, n = 1) through dimethyldecyl (8, n = 8) all have high affinity for the CB1 receptor and are full agonists in vivo. 1',1'-Dimethylundecyl-Delta(8)-THC (8, n = 9) has significant affinity for the receptor (K-i = 25.8 +/- 5.8 nM), but has reduced potency in vivo. The dodecyl analogue (8, n = 10) has little affinity for the CB1 receptor and is inactive in vivo. A quantitative structure-activity relationship study of the side chain region of these compounds is consistent with the concept that for optimum affinity and potency the side chain must be of a length which will permit its terminus to loop back in proximity to the phenolic ring of the cannabinoid.
