Abstract

Official abstract text for this publication.

This invention concerns Selective Progesterone Receptor Modulators (SPRM) in a prodrug form as well as their application in therapy. (3α, 11β,17β)-1 1-[4-(methylsulfonyl)phenyl]-17-(pentafluoroethyl)estra-4,9-diene-3,17-diol (Compound 1) is one of the invention prodrugs.

First claim

Opening claim text (preview).

The invention claimed is: 1. A prodrug of a Selective Progesterone Receptor Modulator (SPRM), wherein the SPRM is (11β,17β)-17-Hydroxy-11-[4-(methylsulphonyl)phenyl]-17-(pentafluoroethyl)estra-4,9-dien-3-one and wherein the prodrug is (3α,11β, 17β)-11-[4-(methyl sulfonyl)phenyl]-17-(pentafluoroethyl)estra-4,9-diene-3,17-diol (Compound 1) or a pharmaceutically acceptable salt thereof. 2. A pharmaceutical composition comprising the prodrug according to claim 1 , optionally admixed with a pharmaceutically acceptable excipient or carrier. 3. A method for fertility control and emergency contraception comprising administering to a patient an effective amount of a prodrug according to claim 1 . 4. A method for the treatment of a gynaecological disease, or a symptom thereof, comprising administering to a patient an effective amount of a prodrug according to claim 1 . 5. The method according to claim 4 wherein the gynaecological disease is selected from the group consisting of Uterine Fibroids, Endometriosis, and symptoms thereof. 6. A method for producing the prodrug according to claim 1 , which method comprises reacting (11β,17β)-17-hydroxy-11-[4-(methylsulfonyl)phenyl]-17-(pentafluoroethyl)estra-4,9-dien-3-one (Compound 2) in the presence of a reducing agent. 7. The method according to claim 6 wherein the prodrug is produced by a reaction that is catalyzed by an isolated Aldo-Keto Reductase (AKR) enzyme. 8. A pharmaceutical composition comprising an isolated Cytochrome P450, a prodrug according to claim 1 , and a pharmaceutically acceptable excipient or carrier. 9. An ex vivo method for activating the prodrug according to claim 1 , which method comprises contacting the prodrug with an activating agent, wherein the activating agent is an isolated Cytochrome P450. 10. The method according to claim 6 wherein the reducing agent is sodium borohydride. 11. The pharmaceutical composition according to claim 8 , wherein the isolated Cytochrome P450 is CYP3A4. 12. The method of claim 9 , wherein the isolated cytochrome P450 is CYP3A4.
