Problems solved by technology

Despite having a rapid onset of action, the magnitude and duration of in vivo CB1 and/or CB2 receptor modulation by many cannabinergic ligands such as Dronabinol and Nabilone are unpredictable due to pharmacokinetic liabilities and erratic pharmacodynamic profiles.
For example, Dronabinol and Nabilone have high lipophilicity (clog P>7), leading to ...

Synthesis of Tricyclic Acid (1.1)

[0150]

Procedure

2-(3,5-dimethoxyphenyl)-2-methylpropanenitrile (1)

[0151]To the stirring suspension of sodium hydride (169.2 mmol) in dry DMF (40 ml) under argon at 0° C. was added drop wise a mixture of 3,5-dimethoxyphenylacetonitrile (56.2 mmol) and iodomethane (169.2 mmol) in dry DMF (40 ml). The reaction mixture was brought to room temperature after stirring at 0° C. for 15 min and stirred for additional 1.5 h. The reaction mixture was quenched with drop wise addition of saturated solution of NH4Cl and diluted with ether. The organic layer was separated and aqueous layer extracted with ether 3 times. The combined organic layers were collected, washed with saturated brine solution, dried over magnesium sulfate and concentrated under vacuum to get crude product which was then chromatographed on silica gel eluting with 25% ethyl acetate / hexane to yield compound 1 as colorless oil (11.01 g, 95% yield). 1H NMR (500 MHz, Chloroform-d) δ ppm 1.71 (s, 6H) ...

example 2

Synthesis of Compounds 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 1.10, 1.24, 1.25, 1.34, 1.35, and 1.36

[0155]Tricyclic acid (1.1) was coupled with side chains using optimized microwave conditions to give respective compounds as shown in scheme 2 and 2a.

[0156]Typical Procedure

[0157]Alkyl side chain (1.5 equivalent) was added to the stirring mixture of 1.1 (1 equivalent) and sodium bicarbonate (1.5 equivalent) in dimethyl formamide (2 ml) in microwave vessel and the resulting solution was heated at 165° C. in microwave for 12 min. The reaction mixture was quenched with water and diluted with ethyl acetate. The organic layer separated and aqueous layer extraced 3 times with ethyl acetate. The combined organic layers were collected, washed with saturated brine, dried over magnesium sulfate and concentrated under vacuum to get crude product which was then chromatographed on silica gel to get pure product.

Synthesis of Compounds 1.11, 1.12, 1.13, 1.14, 1.15, and 1.16

[0172]The synthesis of compounds with monomethyl at 1′ position is depicted in scheme 3, 3a and 3b.

Procedure

2-(3,5-dimethoxyphenyl)propanenitrile (4)

[0173]A solution of 3,5-dimethoxyphenylacetonitrile (28.2 mmoles) and iodomethane (42.3 mmoles) in dry DMF (30 ml) was added at 0° C. to a suspension of sodium hydride (33.8 mmoles, 60% dispersion in oil) in dry DMF (50 ml). The resulting mixture was brought to room temperature and stirred for additional 2 h. The reaction mixture was quenched with saturated ammonium chloride and diluted with ethyl acetate. The organic layer separated and aqueous layer extracted with ethyl acetate three times. The combined organic layers collected, washed with water, saturated brine solution and dried over magnesium sulfate solution to get crude product which is then chromatographed on silica gel eluting with 20% Ethyl acetate:Hexane mixture to get pure intermediate 4 (75% yield) as white solid...

Abstract

Disclosed are compounds and compositions that modulate cannabinoid receptors, methods of modulating cannabinoid receptors, and methods of treating various disorders related to the modulation of cannabinoid receptors. This disclosure is directed to methods of treating cannabinoid dependence, neuropathy, inflammation, glaucoma, a neurodegenerative disorder, a motor function disorder, a gastrointestinal disorder, hypothermia, emesis, loss of appetite, or anorexia associated with AIDS.

Description

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH[0001]The invention was made with government support under Grant DA026795 awarded by NIH / NIDA. The government has certain rights in the invention.FIELD OF THE INVENTION[0002]The present disclosure is in the field of medicinal chemistry. More specifically, this disclosure relates to cannabinoid derivatives and the use of such compounds in methods for treating cannabinoid dependence, pain, inflammation, neuropathy, neurodegenerative disease, anxiety disorder, motor function disorder, fertility disorder, gastrointestinal disorder, appetite disorder, metabolic disorder, movement disorder, and cancer.BACKGROUND[0003]Presently, two Gi / o protein coupled cannabinoid receptors have been characterized in mammals and other organisms: CB1, a central receptor found in the mammalian brain and a number of other sites in peripheral tissues; and CB2, a peripheral receptor found principally in cells related to the immune system. Compounds known as canna...
