  • Publication number: 20100210860
    Abstract: The present invention relates to a method for the preparation of dronabinol ((6aR-trans)-6a,7,8,10a-tetrahydro-6,6,9-trimethyl-3-pentyl-6H-dibenzo[b,d]pyran-1-ol, ?9-tetrahydrocannabinol (?9-THC)) from cannabidiol (CBD) by cyclization of cannabidiol (CBD) (2-[1R-3-methyl-6-(1-methylethenyl)-2-cyclohexene-1-yl]-5-pentyl-1,3-benzoldiol) to ?9-THC. The method according to the present invention is characterized in that cannabidiol (CBD) (B) is present in an organic solvent and cyclized to ?9-THC in the presence of a molecular sieve while being heated. It was found out that, in the method of the present invention, the molecular sieve not only has the previously mentioned drying properties, but also exhibits strong catalytic properties which are important in this reaction. Normally, cyclizations carried out in the presence of a Lewis acid catalyst only are distinctly slower and the ?9-THC yield is lower than in cyclizations carried out in the present of a molecular sieve.

  • Patent number: 6939977
    Abstract: Disclosed are novel compounds represented by the following structural formula: R-X-Y; and physiologically acceptable salts thereof. R is a tricyclic core of a cannabinoid or substituted cannabinoid. X is a covalent bond, —CH2— or —CHR1—, wherein R1 a C1 to C3 substituted or unsubstituted alkyl group. Y is a heterocyclic ring, a substituted heterocyclic ring, a carbocyclic ring, a substituted carbocyclic ring, a fused bicyclic ring system, a substituted fused bicyclic ring system, a bridged bicyclic ring system, a substituted bridged bicyclic ring system, a bridged tricyclic ring system or a substituted bridged tricyclic ring system. Also disclosed is a method of stimulating a CB1 and/or CB2 receptor in a subject. The method comprises administering to the subject a therapeutically effective amount of R-X-Y.

  • Publication number: 20040049059
    Abstract: The invention relates to a method for producing an extract from cannabis plant matter, containing tetrahydrocannabinol, cannabidiol and optionally the carboxylic acids thereof. According to said method, the dried plant matter is ground and subjected to a CO2 extraction and the primary extract obtained is separated. The invention method permits &Dgr;8 or &Dgr;9 tetrahydrocannabinol to be selectively obtained both from industrial hemp and from drug-producing hemp, optionally after dissolving the primary extract in ethanol, separating undesirable waxes and removing the solvent under reduced pressure.

  • Patent number: 6610737
    Abstract: Novel non-psychotropic cannabinoids are disclosed and pharmaceutical compositions comprising these novel compounds are described for preventing neurotoxicity, neuroinflammation, immune or inflammatory disorders comprising as active ingredient the stereospecific (+) enantiomer, having (3S,4S) configuration of &Dgr;6 tetrahydrocannabinol type compounds. The compositions are particularly effective in alleviating and even preventing neurotoxicity due to acute injuries to the central nervous system, including mechanical trauma, compromised or reduced blood supply as may occur in cardiac arrest or stroke, or poisonings. They are also effective in the treatment of certain inflammatory disorders and chronic degenerative diseases characterized by neuronal loss and chronic pain including neuropathic pain.
