- Synthetic Nonpsychotropic Cannabinoids with Potent Antiinflammatory, Analgesic, and Leukocyte Antiadhesion Activities
-
Two strategies for the design of therapeutically useful cannabinoids have been combined to produce compounds with greatly increased antiinflammatory activity and with a low potential for adverse side effects.Enantiomeric cannabinoids with a carboxylic acid group at position 7 and with an elongated and branched alkyl sidechain at position 5' have been synthesized and tested for antiinflammatory activity.They were effective when given orally at doses of 10 μg/kg in reducing paw edema in mice that had been induced by either arachidonic acid or platelet activating factor.Leukocyte adhesion to culture dishes was also reduced in peritoneal cells from mice in which the cannabinoids were orally administered in the same dose range as for the paw edema tests.Antinociception could be observed in the mouse hot plate assay; however, little stereochemical preference was seen in contrast to the above tests where the 3R,4R compounds are more active than the 3S,4S enantiomers.Finally, in agreement with earlier reports on the naturally occurring pentyl side chain acids, the synthetic acids showed little activity in producing catalepsy in the mouse, suggesting that they would be nonpsychotropic in humans.

- Ultrapure ajulemic acid has improved CB2 selectivity with reduced CB1 activity
-
Ajulemic acid, a side-chain analog of Δ8-THC-11-oic acid, was designed as a potent therapeutic agent free of the psychotropic adverse effects typical of most cannabinoids. Subsequent studies of ajulemic acid have yielded widely divergent findings on the occurrence of these adverse effects. To help resolve these discrepancies, we have prepared highly purified ajulemic acid using a different synthetic method than previously reported in the literature and compared its cannabinoid receptor binding constants with those obtained using several other preparations from different sources. Whereas CB2 binding did not vary greatly among all of the samples, the CB1 binding showed a wide range of affinities. The highly purified product (JBT-101) reported here had the weakest affinity for CB1 while the original preparation (HU-239) showed the strongest affinity for CB1. The CB1/CB2 ratio of affinities was 12.3 for JBT-101 whereas that for HU-239 was 0.19, a 65-fold difference. Functional responses such as catalepsy and hypothermia using JBT-101 versus HU-239 displayed reduced CB1 activity in keeping with the receptor binding data. Thus, earlier conclusions on the limited therapeutic index for ajulemic acid need to be reconsidered in the light of the data now obtained using JBT-101.

- Studies on the synthesis of (-)-11-nor-9-carboxy-Δ9-tetrahydrocannabinol (THC) and related compounds: An improved oxidative procedure
-
A facile procedure is described whereby Δ9-THC aldehydes 4, as their tert-butyldimethylsilyl derivatives, are conveniently oxidized to the corresponding acids with sodium chlorite in the presence of a large excess of 2-methyl-2-butene without isomerization of the Δ9-double bond. Deprotection of the O-protecting group with tetrabutylammonium fluoride in tetrahydrofuran gave the acids 2 in an overall yield of ≥80%. A study of other oxidizing agents and protecting groups demonstrated that this is the procedure of choice for the preparation of 9-carboxy-Δ9-tetrahydrocannabinols.
