  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.

  receptor. Exceptionally high CB2 affinity was observed for 1-deoxy-9beta-hydroxy-dimethylhexylhexahydrocannabinol (JWH-361, 9, n = 3) K(i) = 2.7 nM and 1-deoxy-9beta-hydroxydimethylpentylhexahydrocannabinol (JWH-300, 9, n = 2) K(i) = 5.3 nM. In general, the stereochemistry of the 9-hydroxy group is important and the beta-orientation enhances both CB2 receptor affinity and selectivity.

  Delta(8)-Tetrahydrocannabinol (26), 3-(1',1'-dimethylbutyl)- (12), 3-(1',1'-dimethylpentyl)- (13), 3-(1',1'-dimethylhexyl)- (14) and 3-(1',1'-dimethylheptyl)-Delta(8)-tetrahydrocannabinol (15) have been converted into the corresponding 1-bromo-1-deoxy-Delta(8)-tetrahydrocannabinols (25, 8-11). This was accomplished using a protocol developed in our laboratory in which the trifluoromethanesulfonate of a phenol undergoes palladium mediated coupling with pinacolborane. Reaction of this dioxaborolane with aqueous-methanolic copper(II) bromide provides the aryl bromide. The affinities of these bromo cannabinoids for the cannabinoid CB1 and CB2 receptors were determined. All of these compounds showed selectivity for the CB2 receptor and one of them, 1-bromo-1-deoxy-3-(1',1'-dimethylhexyl)-Delta(8)-tetrahydrocannabinol (10), exhibits 52-fold selectivity for this receptor with good (28 nM) affinity.
