11-Hydroxy-3-(1',1'-dimethylheptyl)hexahydrocannabinol (1) was synthesized from the known cannabimimetic analog (+/-)-nabilone. Racemic 1 was resolved by HPLC on a semipreparative CHIRALCEL OD column (Daicel, Inc.), and pharmacological activities of the individual enantiomers were evaluated in the mouse model. The (-)-enantiomer was found to be much more potent than the (+)-enantiomer in all the four measures with the potency ratios in the production of catalepsy (RI), hypoactivity (SA), hypothermia (RT), and antinociception (TF) being 93, 143, 186, and 322, respectively. The racemic 11α-OH diastereomer (2), a reaction side product, was also evaluated in the mouse model. Only small differences in the pharmacological activity of racemic 1 and 2 were found in the above four measures.

The 1,1-dimethylheptyl (DMH) homologue of 7-hydroxy-Δ6-tetrahydrocannabinol (3) is the most potent cannabimimetic substance reported so far.Hydrogenation of 3 leads to a mixture of the epimers of 5'-(1,1-dimethylheptyl)-7-hydroxyhexahydrocannabinol or to either the equatorial (7) or to the axial epimer (8), depending on the catalysts and conditions used.Compound 7 discriminates for Δ1-THC (2) in pigeons (ED50 = 0.002 mg/kg, after 4.5 h), at the potency level of 3, and binds to the cannabinoid receptor with a KD of 45 pM, considerably lower than the Ki of 180 pM measured for compound 3 and the Ki of 2.0 nM measured for CP-55940 (1), a widely employed ligand.Tritiated 7 was used as a novel probe for the cannabinoid receptor.
