Treatment Of Immune Dysregulation Using Cannabinoid Derivatives

a cannabinoid derivative and immune system technology, applied in the direction of biocide, heterocyclic compound active ingredients, organic compounds of group 5/15, etc., can solve the problems of patients' failure to comply, virus subversion and progressively destroy the very system on which it is relied, and mixed attempts to achieve the effect of attenuating the dysfunction of the immune system

Problems solved by technology

While a host immune response is mounted against such HIV proteins, due in part to the high degree of mutability of such proteins and their varied glycosylation patterns, such immune response usually is incomplete, resulting in a pool of latent virus that effectively avoids immune surveillance.
Over time, the virus gradually subverts and progressively destroys the very system relied on to ward off infections.
However, due in part to the ability of the virus to spread by syncytia or direct cell-to-cell contact and its ability to acquire ICAM molecules, such attempts have met with mixed results.
Failure of patients to comply with such regimens adds to the failure rate of antiviral therapy.
Many thousands of people are diagnosed with cancer and other neoplastic disorders each year, and although advances have been made in cancer therapy, the existing treatments are not successful in many cases.
For example, many anticancer drugs administered to patients often have toxic effects on non-cancerous cells in the patient's body.
Thus, patients with many types of malignancies remain at significant risk for relapse and mortality.

example 1

[0279]This example demonstrates the synthesis of a compound according to Formula I. A mixture of 2,6-dimethoxyphenol (73.4 g, 0.48 mole), 2,6-dimethyl-2-heptanol (69.0 g, 0.48 mole) and methanesulfonic acid (95 mL) was stirred at 50° C. for 3 h and then at room temperature overnight. The mixture was poured over ice-water (600 mL) with stirring. The mixture was extracted with CH2Cl2 (2×200 mL). The extracts were washed with water, saturated aqueous NaHCO3, saturated aqueous sodium chloride solution and dried over anhydrous Na2SO4. The solution was concentrated under reduced pressure to obtain the product as an oil (130 g, 96%). Analysis of this substance (MS (NAB) m / z 281 (MH)′; 3H NMR (CDCl3) 50.80 (d, 611), 1.0-1.1 (m, 4H), 1.27 (s, 611), 1.40-1.60 (m, 3H), 3.89 (s, 6H), 5.36 (s, 111), 6.54 (s, 211)) revealed it to be 4-(1,1,5-trimethylhexyl)-2,6-dimethoxy phenol:

example 2

[0280]This example demonstrates the synthesis of a compound according to Formula I.

[0281]A solution of crude 4-(1,1,5-trimethylhexyl)-4,6, dimethoxyphenol from Example 1 (130 g, 0.46 mole) in dry CCl4 (100 mL) was cooled in ice-bath and diethyl phosphite (70 mL, 0.54 mole) was added. To the stirred mixture triethylamine (75 mL, 0.54 mole) was added drop-wise at such a rate as to maintain the temperature of the reaction mixture below 10° C. The reaction mixture was stirred in the ice-bath for 2 h and at room temperature overnight. The mixture was then diluted with CH2Cl2 (200 mL), washed with water, 4N aqueous NaOH (100 mL), IN aqueous HCl (125 mL), water and saturated aqueous sodium chloride solution. The extracts were dried over anhydrous Na2SO4 and concentrated under reduced pressure. The crude product was purified by chromatography over a column of silica using cyclohexane:EtOAc (7:1 to 3:1 gradient) as the eluent to obtain 103 g (54%) of the product as a colorless waxy oil.

example 3

[0282]This example demonstrates the synthesis of a compound according to Formula I. A solution of 4-(1,1,5-trimethylhexyl)-2,6-dimethoxyphenyl diethyl phosphate from Example 2 (82 g, 0.197 mole) in Et2O (175 mL) and THE (35 mL) was added slowly to liquid ammonia (450 mL) contained in a 3-neck vessel fitted with mechanical stirrer, thermometer, dry ice condenser and a pressure equalizing addition funnel while adding small freshly cut pieces of lithium wire (2.8 g, 0.40 g-atom) at such a rate as to maintain a blue color. The reaction mixture was stirred further for an hour and then quenched by the addition of saturated aqueous NH4C1 (22 mL). Ether (220 mL) was added and the ammonia was allowed to evaporate overnight. The residue was treated with water (220 mL). The layers were separated and the ether layer was washed with 4N NaOH (200 mL), water (2×200 mL) and saturated aqueous sodium chloride solution. The organic extracts were dried (MgSO4) and concentrated under reduced pressure. T...

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This is a divisional application of U.S. patent application Ser. No. 11 / 978,344 filed on Oct. 29, 2007, which is a continuation of U.S. patent application Ser. No. 10 / 328,242 (now U.S. Pat. No. 7,105,685), filed Dec. 22, 2002, which is a continuation of application Ser. No. 09 / 928,683 (now U.S. Pat. No. 6,566,560) filed on Aug. 13, 2001, which is a continuation-in-part of U.S. patent application Ser. No. 09 / 533,386 (now U.S. Pat. No. 6,274,635) filed on Mar. 22, 2000, which claims priority to U.S. provisional patent application Nos. 60 / 125,674 and 60 / 151,595 filed on Mara 22, 1999 and Aug. 30, 1999, respectively.BACKGROUND OF THE INVENTION[0002]The retroviral Human Immunodeficiency Viruses (HIV) 1 and 2 are the most common causative agents of AIDS. Through a portion of a viral envelope protein (gp120), HIV binds specifically and with high affinity to the CD4 molecule on T-lymphocytes. Following binding, the virus fuses with the cell membr...
