CANNABINOID DERIVATIVES
-
Paragraph 0144, (2021/04/10)
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

Page/Page column 51; 54; 56, (2020/12/30)
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.
PROCESS FOR PURIFICATION OF CANNABINOIC ACIDS FROM PLANT MATERIAL EXTRACT
-
Paragraph 0037, (2020/02/14)
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.
METHODS FOR SYNTHESIS OF CANNABINOID COMPOUNDS
-
Paragraph 0032-0033, (2020/03/02)
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.
SYNTHESIS OF PHYTOCANNABINOIDS INCLUDING A DEMETHYLATION STEP
-
, (2019/03/05)
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
-
Sheet 1/4, (2016/04/09)
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.
