Competitive progesterone antagonists, including two novel steroids, viz., 11β,19-[4-(cyanophenyl)-o-phenylene]-17β-hydroxy-17α-(3-hydroxyprop-1(Z)-enyl)-4-androsten-3-one and 11β,19-[4-(3-pyridinyl)-o-phenylene]-17β-hydroxy-17α-(3-hydroxyprop-1(Z)-enyl)-4-androsten-3-one, inhibit formation of endometrial glands at below their ovulation inhibiting dose and the abortive dose, and thus achieve oral contraception in females without adversely affecting the menstrual cycle and without risk of aborting a previous implanted fertilized egg or a fetus.

The invention belongs to the technical field of medicine and relates to a 1,4-dihydrobithiophene [3', 2': 5, 6] bithiapyran [4, 3-c] pyrazol-3-carboxylic acid derivative and application thereof used as an estrogen receptor, in particular to a 1,4-dihydrobithiophene [3', 2': 5, 6] bithiapyran [4, 3-c] pyrazol-3-carboxylic acid derivative and a pharmaceutically acceptable salt, or a stereoisomer thereof and a prodrug as well as a pharmaceutically acceptable vector in compatibility or a diluent used as an estrogen receptor. The structural general formula of the derivative is disclosed in the specification, and in the structural formula, n R1 can be independently selected from a substituted or unsubstituted amido group, and R2 can be independently selected from H or an acetyl group. The derivative can be used for treating and preventing various diseases related to estrogen functions, such as diseases related to estrogen deficiency, estrogen sensitive cancer and hyperplasia, endometriosis, uterus myoma and osteoarthritis. Compounds or compositions of the derivative can also be independently used or combined with progestogen or a hormoneantagonist as a contraceptive.

The subject matter of the instant invention is pertinent to the field of cancer treatment. In particular, the instant invention is relevant to the treatment and or prevention of breast cancer in a patient. Compositions for practicing the methods, comprising selective progesterone receptor modulators, which function as progesterone agonists in the uterus and as progesterone antagonists in the breast tissue and exhibit only low affinity for glucocorticoid and estrogen receptors, are also disclosed. Embodiments of the instant invention also disclose methods for preventing the development of breast cancer in patients undergoing hormone replacement therapy or estrogen therapy.
