Abstract

Compounds of formula IA or IB are provided where X₁, X₂ and X₃ are independently selected from H or hydroxy protecting groups and R₁ is selected from straight or branched chain alkyl groups having from 1 to 8 carbon atoms; straight or branched chain alkenyl groups having from 2 to 8 carbon atoms; straight or branched chain hydroxy-substituted alkyl groups having from 1 to 8 carbon atoms; straight and branched chain hydroxy-substituted alkenyl groups having from 2 to 8 carbon atoms. Such compounds are used in preparing pharmaceutical compositions and are useful in treating a variety of biological conditions.

Claims

1. A compound having the formula IA or IB

2. The compound of claim 1, wherein X₁, X₂ and X₃ are hydroxy protecting groups.

3. The compound of claim 2, wherein X₁, X₂ and X₃ are t-butyldimethylsilyl groups.

4. The compound of claim 1, wherein X₁, X₂ and X₃ are H and R₁ is CH₃ and the compound has the formula IIA or IIB

5. A pharmaceutical composition, comprising an effective amount of the compound of claim 1 and a pharmaceutically acceptable carrier.

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