Abstract

A method of generating synthetic metabolites of tanaproget derivatives thereof is provided. These compounds and methods of using these derivatives for detecting tanaproget metabolites in samples are provided.

Claims (20)

1. An isolated and purified S-glucuronide of tanaproget characterized by the structure:

2. A synthetic S-glucuronide of tanaproget characterized by the structure:

3. The synthetic S-glucuronide of tanaproget of claim 2 having a purity of greater than about 98%.

4. The synthetic S-glucuronide of tanaproget of claim 2 prepared by reacting tanaproget, sodium hydride, and acetobromo-α-D-glucuronide acid methyl ester.

5. The synthetic S-glucuronide of tanaproget of claim 2 prepared by:

(a) reacting tanaproget, sodium hydride, and acetobromo-α-D-glucuronide acid methyl ester;

(b) reacting the product of step (a) with a solution of methanol and Hunig's base; and

(c) acidifying the product of step (b) using hydrochloric acid.

6. The synthetic S-glucuronide of tanaproget of claim 5 , further prepared by:

(d) separating the synthetic S-glucuronide of tanaproget by chromatography.

7. A composition comprising a pharmaceutically acceptable carrier and a S-glucuronide of tanaproget according to claim 2 .

8. A method for preparing a synthetic S-glucuronide of tanaproget characterized by the structure:

said method comprising reacting tanaproget, sodium hydride, and acetobromo-α-D-glucuronide acid methyl ester.

9. A method for preparing a synthetic S-glucuronide of tanaproget characterized by the structure:

said method comprising:

(a) reacting tanaproget, sodium hydride, and acetobromo-α-D-glucuronide acid methyl ester;

(b) reacting the product of step (a) with a solution of methanol and Hunig's base; and

(c) acidifying the product of step (b) using hydrochloric acid.

10. The method according to claim 9 , further comprising:

(d) separating the synthetic S-glucuronide of tanaproget using chromatography.
