- CANNABINOID DERIVATIVES
-
This disclosure relates generally to cannabinoid derivatives having the formula (I), wherein R4 is hydrogen, -C(Q1)N(R4a)(R4b) or -C(R4J)(R4k)N(R4e)C(0)R4f, R6 is hydrogen, -C(Q2)N(R6a)(R6b) or -C(R6J)(R6k)N(R6e)C(0)R6f, provided that R6 is not hydrogen when R4 is hydrogen. Pharmaceutical compositions for the prevention or treatment of a disease associated with a cannabinoid receptor (such as CB1 or CB2) in a subject in need thereof, and methods of using the cannabinoid derivatives are also described.

- METHODS FOR EXTRACTION, PROCESSING, AND PURIFICATION OF A SELECTED FAMILY OF TARGET COMPOUNDS FROM CANNABIS
-
Disclosed are methods for separating, recovering, and purifying tetrahydrocannabinolic acid (THCA) salts from an organic solvent solution comprising a mixture of cannabinoids. The methods comprise solubilizing the mixture of cannabinoids in a selected C5-C7 hydrocarbon solvent, adding thereto a selected amine to thereby precipitate a THCA-amine salt therefrom, dissolving the recovered THCA-amine salt in a selected solvent and then adding thereto a selected antisolvent to thereby recrystallize a purified THCA-amine salt therefrom. The recrystallized THCA-amine salt may be decarboxylated to form a mixture of Δ9-tetrahydrocannabinol (Δ9-THC) and amine. The Δ9-THC amine mixture may be acidified to separate the amine from Δ9-THC. The recovered Δ9-THC may be concentrated to produce a highly purified Δ9-THC. Also disclosed are THCA-amine salts produced with amines selected from groups of diamines, amino alcohols, and tertiary amines.

- METHODS FOR SYNTHESIS OF CANNABINOID COMPOUNDS
-
The present invention provides simple synthetic routes for the preparation of cannabinoid compounds such as CBD, CBDV, THC, THCV, CBN, HU-308, CBG, CBC, and derivatives thereof, which are stereoselective and provide the desired cannabinoid compound in high yield.

- PROCESS FOR PURIFICATION OF CANNABINOIC ACIDS FROM PLANT MATERIAL EXTRACT
-
The present invention relates to a highly economic process for the purification of a cannabinoid acid, more specifically THCA or CBDA, from either a crude cannabis plant material or a cell culture of said cannabis plant, using ion exchange resins. The purified cannabinoid acid obtained may then be decarboxylated to yield the corresponding cannabinoid, i.e., THC or CBD, respectively.

- SYNTHESIS OF PHYTOCANNABINOIDS INCLUDING A DEMETHYLATION STEP
-
A method for demethylating a methylated phytocannabinoid compound of Formula I to form a phytocannabinoid compound of Formula II: Formula I Formula II wherein: R1 is selected from the group consisting of: substituted or unsubstituted C1-C5 alkyl; R2 is selected from the group consisting of: OH or O, and R3 is selected from the group consisting of: a substituted or unsubstituted cyclohexene, a substituted or unsubstituted C2-C8 alkene, or a substituted or unsubstituted C2-C8 dialkene; or R2 is O, and R2 and R3 together form a ring structure in which R2 is an internal ring atom; wherein the method includes: heating a reaction mixture comprising the methylated phytocannabinoid compounds and a polar aprotic solvent in the presence of a dissolved inorganic alkaline salt for a time sufficient to demethylate at least a portion of the methylated phytocannabinoid compounds and form the phytocannabinoid compound.

- CANNABICHROMENIC ACID SYNTHASE FROM CANNABIS SATIVA
-
Nucleic acid molecules from cannabis have been isolated and characterized and encode polypeptides having cannabichromenic acid synthase activity. Expression or over-expression of the nucleic acids alters levels of cannabinoid compounds. The polypeptides may be used in vivo or in vitro to produce cannabinoid compounds.
