Abstract

Compounds of formula I are provided where X¹ and X² 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 and X² are both 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
