Abstract

Compounds of formula I are provided where X¹, X², and X³ are independently selected from H or hydroxy protecting groups. Such compounds may be used in preparing pharmaceutical compositions and are useful in treating a variety of biological conditions.

Claims

1. A compound having the formula I

2. The compound of claim 1, wherein X¹ and X² are both hydroxy protecting groups.

3. The compound of claim 2, wherein X¹ and X² are both t-butyldimethylsilyl groups.

4. The compound of claim 1, wherein X¹, X², and X³ are all H and the compound has the formula IA

5. A pharmaceutical composition, comprising an effective amount of the compound of claim 4 and a pharmaceutically acceptable carrier.

6. The pharmaceutical composition of claim 5 wherein the effective amount comprises from about 0.01 μ

g to about 1 mg of the compound per gram of the composition.

7. The pharmaceutical composition of claim 5 wherein the effective amount comprises from about 0.1 μ

g to about 500 μ

g of the compound per gram of the composition.

8. A method of treating a subject suffering from a biological condition, comprising administering an effective amount of the compound of claim 4 to the subject, wherein the biological condition is selected from psoriasis;

leukemia;

colon cancer;

breast cancer;

prostate cancer;

multiple sclerosis;

lupus;

diabetes mellitus;

host versus graft reaction;

rejection of organ transplants;

an inflammatory disease selected from rheumatoid arthritis, asthma, or inflammatory bowel diseases;

a skin condition selected from wrinkles, lack of adequate skin firmness, lack of adequate dermal hydration, or insufficient sebum secretion;

renal osteodystrophy;

or osteoporosis.

9. The method of claim 8, wherein the biological condition is psoriasis.

10. The method of claim 8, wherein the biological condition is selected from leukemia, colon cancer, breast cancer, or prostate cancer.
