  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.

  Cannabinoid analogues that exhibit specificity for the CB 2 cannabinoid receptor are provided. The analogues are 1-methoxy-, 1-deoxy-11-hydroxy- and 11-hydroxy-1-methoxy-Δ 8 -tetrahydrocannabinols and 1-alkyl-3(1-naphthoyl)indoles. The compounds are useful for the treatment of pain (especially pain resulting from inflammation) and cancer (especially glioma tumors).

  Three series of new cannabinoids were prepared and their affinities for the CB(1) and CB(2) cannabinoid recptors were determined. These are the 1-methoxy-3-(1',1'-dimethylalkyl)-, 1-deoxy-11-hydroxy-3-(1',1'-dimethylalkyl)- and 11-hydroxy-1-methoxy-3-(1',1'-dimethylalkyl)-Delta(8)-tetrahydrocannabinols, which contain alkyl chains from dimethylethyl to dimethylheptyl appended to C-3 of the cannabinoid

  准备了三个系列的新大麻素，并确定了它们与CB（1）和CB（2）大麻素亲和力的亲和力。这些是1-甲氧基-3-（1'，1'-二甲基烷基）-，1-脱氧-11-羟基-3-（1'，1'-二甲基烷基）-和11-羟基-1-甲氧基-3 -（1'，1'-二甲基烷基）-Delta（8）-四氢大麻酚，其中含有从二甲基乙基到二甲基庚基的烷基链，该烷基链附加在大麻素的C-3上。所有这些化合物对CB（2）受体的亲和力均大于对CB（1）受体的亲和力，但是只有1-甲氧基-3-（1'，1'-二甲基己基）-Delta（8）-THC（JWH- 229，6e）实际上对CB（1）受体没有亲和力（K（i）= 3134 +/- 110nM），对CB（2）的亲和力很高（​​K（i）= 18 +/- 2nM）。

  and CB2 receptors were determined employing previously described procedures. Five of the 3-(1',1'-dimethylalkyl)-1-deoxy-delta8-THC analogues (2, n = 1-5) have high affinity (Ki = < 20 nM) for the CB2 receptor. Four of them (2, n = 1-4) also have little affinity for the CB1 receptor (Ki = > 295 nM). 3-(1',1'-Dimethylbutyl)-1-deoxy-delta8-THC (2, n = 2) has very high affinity for the CB2 receptor (Ki
