The synthesis of sterols (cholestane, Vitamin D, and cholesterol) starts with squalene. Typically, cholesterol BACKGROUND OF THE INVENTION synthesis takes place in the cytoplasm of liver and intestinal cells through hydroxymethylglutaryl-CoA reductase (HMG 0001.

There is therefore a need to finding 0002 Throughout the world there are public and govern additional targeted therapies to treat cancer with fewer side ment concerns about the increasing prevalence cancer. Many effects as compared to conventional therapies. treatments exist but severe side effects and limited survival rate are pushing the research community into new approaches SUMMARY OF THE INVENTION for treatments. 0003 Cancer is a disease marked by the uncontrolled 0010. The invention features a substantially pure prepara growth of abnormal cells. Cancer cells have overcome the tion of a compound described by the formula (I) barriers imposed on normal cells, which have a finite lifespan, to grow indefinitely. As the growth of cancer cells continue, genetic alterations may persist until the cancerous cell has (I) manifested itself to pursue a more aggressive growth pheno type. If left untreated, metastasis, the spread of cancer cells to distant areas of the body by way of the lymph system or bloodstream, may ensue, destroying healthy tissue. 0004. According to a recent American Cancer Society study, approximately 1,268,000 new cancer cases were expected to be diagnosed in the United States in the year 2001 alone. Lung cancer is the most common cancer-related cause of death among men and women, accounting for over 28% of all cancer-related deaths. It is the second most commonly occurring cancer among men and women; it has been esti mated that there were more than 169,000 new cases of lung cancer in the U.S. in the year 2001, accounting for 13% of all new cancer diagnoses. While the rate of lung cancer cases is or a prodrug thereof. declining among men in the U.S., it continues to increase I0011. In formula (I), each of Rs. Rs, and R is, indepen among women. According to the American Cancer Society, dently, selected from OH, SH, and NH; the stereochemistry an estimated 157,400 Americans were expected to die due to at positions 3, 5, and 6 is either 3C, 53, 6(3 or 3 B, 5C, 6C.: each lung cancer in 2001. of R-7, Rs.

An exemplary compound of formula (I) has the structure: 0005 Cells require a flexible, permeable, fluid, active membrane. The cell membrane, which defines the cell and boundaries of cell organelles, is generally composed of lipid (II) cholesterol, phospholipids, sphingolipids, proteins, and car bohydrates. Cholesterol plays an important role in the flex ibility, the fluidity, and the permeability of the membrane and the maintenance of these properties across a range of tem peratures. Cholesterol Synthesis and Uptake 0006 Mammalian cells receive cholesterol through uptake of exogenic cholesterol and endogenous synthesis. 0007 Exogenic uptake is mediated by specific receptors on the membrane itself: cholesterol is adsorbed from body H fluids in contact with the cell. This uptake occurs through endocytosis of lipoprotein particles that contain cholesterol. 0012. The compound can be part of a composition also The isomerization process of the phosphatidylcholine (FIG. including a pharmaceutically acceptable carrier and be Suit 2) CC double bond cis/trans allow phospholipids with low able for oral, intravenous, topical, Subcutaneous, buccal, density lipoprotein to contain specific receptors for choles intramuscular, inhalation, intrathecal, intraarticular, intratu terol adsorption. Most animal cells acquire cholesterol by moral, or rectal administration. When formulated for oral receptor-mediated endocytosis of low density lipoproteins administration, the compound can be present, for example, in that contain cholesterol to form endosomes which migrate to an amount between 0.005 mg and 500 mg, more desirably lysosomes for degradation and release of cholesterol into the between 1 mg and 100 mg (e.g., 1, 5, 10, 20, 25, 30, 50, 75, or cell. 100 mg).

The invention also features a process for preparing dermatitis; alopecia greata; alopecia universalis; amyloido 24-ethyl cholestane 3,5,6 triol comprising the step of oxidiz sis; anaphylactoid purpura; anaphylactoid reaction, aplastic ing sitosterol. Using this process, for example, 24-ethyl anemia; angioedema, hereditary; angioedema, idiopathic; cholestane 3 B.5C,6O. triol can be prepared from B-sitosterol, ankylosing spondylitis; arteritis, cranial; arteritis, giant cell; and 24-ethyl cholestane 3C.5 B.6? triol can be prepared from arteritis, Takayasu’s; arteritis, temporal; asthma; a-telang C-sitosterol. There are many methods by which the sitosterol iectasia; autoimmune oophoritis; autoimmune orchitis; can be oxidized to prepare 24-ethyl cholestane 3,5,6 triol.
