Compounds and compositions for inhibiting estrogen sulfotransferase transferase activity, process and novel intermediates therein

摘要

The present invention concerns the novel compounds having fluoro, amino, nitro or hydroxy monosubstituted at the 2- or 4- position on deoxyestrone as well as deoxyestra-17-ol. The compounds are useful as estrogen sulfotransferase inhibitors. Such estrogen sulfotransferase inhibition provides the novel use for treating a female mammal to prevent implantation of a blastocyst. Additionally, the invention concerns the novel synthesis and novel intermediates in the synthesis of the estrogen sulfotransferase inhibiting compound of the present invention.
