Nuclear receptor binding agents
The present invention relates to a novel class of selective estrogen receptor modulators (SERMs). The SERM compounds are applicable for use in the prevention and/or treatment of a variety of diseases and conditions including prevention and treatment of cancers such as prostate and breast cancer, osteoporosis, hormone-related diseases, hot flashes or vasomotor symptoms, neurological disorders, cardiovascular disease and obesity.

7. The pharmaceutical composition of claim 3 , wherein the pharmaceutical composition is for topical application to the skin surface of the subject.
8. The pharmaceutical composition of claim 3 , wherein the pharmaceutical composition is a pellet, a tablet, a capsule, a solution, a suspension, an emulsion, an elixir, a gel, a cream, a suppository or a parenteral formulation.
9. The pharmaceutical composition of claim 8 , wherein said pharmaceutical composition is a patch.
10. A composition comprising the nuclear receptor binding agent (NRBA) compound of 1 and a suitable carrier or diluent.
11. A method of treating osteoporosis in a subject, the method comprising administering a composition comprising the nuclear receptor binding agent (NRBA) of claim 1 to said subject.
12. A method of improving a lipid profile in a subject, the method comprising administering a pharmaceutical composition comprising the nuclear receptor binding agent (NRBA) of claim 1 to said subject.
13. A method of treating androgen-deprivation induced osteoporosis, bone fractures and/or loss of bone mineral density (BMD) in men having prostate cancer, the method comprising administering a pharmaceutical composition comprising the nuclear receptor binding agent (NRBA) of claim 1 to a male subject in need, having prostate cancer.
14. A method of ameliorating symptoms and/or clinical complications associated with menopause in a female subject, the method comprising administering a pharmaceutical composition comprising the nuclear receptor binding agent (NRBA) of claim 1 to a female menopausal subject.
15. A method of treating prostate cancer in a subject, the method comprising administering a pharmaceutical composition comprising the nuclear receptor binding agent (NRBA) of claim 1 to said subject.
16. A method of treating, inhibiting or reducing the risk of breast cancer in a subject, comprising administering a pharmaceutical composition comprising a nuclear receptor binding agent (NRBA) of claim 1 to said subject.
17. A method of reducing circulating lipid levels in a male subject with prostate cancer having undergone Androgen Deprivation Therapy (ADT), said method comprising administering to said subject a composition comprising a nuclear receptor binding agent (NRBA) of claim 1 .
18. The method of claim 17 , wherein said lipid levels, which are reduced comprise a triglyceride, low density lipoprotein (LDL) cholesterol, or a combination thereof.
19. The method of claim 17 , wherein said method comprises increasing circulating levels of high density lipoprotein (HDL) cholesterol in said subject.
20. The method of claim 17 , wherein said method further comprises reducing the ratio of total circulating cholesterol levels to high density lipoprotein (HDL) levels in said subject.
21. The method of claim 17 , wherein said subject further suffers from atherosclerosis and its associated diseases, premature aging, Alzheimer's disease, stroke, toxic hepatitis, viral hepatitis, peripheral vascular insufficiency, renal disease, hyperglycemia, or any combination thereof.
22. The nuclear receptor binding agent (NRBA) of claim 1 , in the form of its pharmaceutically acceptable salt.
23. The nuclear receptor binding agent (NRBA) compound of claim 22 , wherein said pharmaceutically acceptable salt is a bisulfate, borate, bromide, chloride, hemisulfate, hydrobromate, hydrochlorate, hydroxyethylsulfonate, iodate, iodide, isothionate, nitrate, persulfate, phosphate, sulfate, sulfamate, sulfanilate, sulfonic acid, sulfonate or thiocyanate.
24. The nuclear receptor binding agent (NRBA) compound of claim 22 , wherein said pharmaceutically acceptable salt is a hydrochloride salt.
25. A method of reducing the severity of osteoporosis in a subject, the method comprising administering a composition comprising the nuclear receptor binding agent (NRBA) of claim 1 to said subject.
26. A method of reducing the incidence of, inhibiting or suppressing androgen-deprivation induced osteoporosis, bone fractures and/or loss of bone mineral density (BMD) in men having prostate cancer, the method comprising administering a pharmaceutical composition comprising the nuclear receptor binding agent (NRBA) of claim 1 to said subject.
27. A method of suppressing, inhibiting, or reducing the incidence of hot flashes, gynecomastia, and/or hair loss in a male subject having prostate cancer, the method comprising administering a pharmaceutical composition comprising the nuclear receptor binding agent (NRBA) of claim 1 to said subject.
28. A method of suppressing, inhibiting or reducing the risk of developing prostate cancer in a subject, the method comprising administering a pharmaceutical composition comprising the nuclear receptor binding agent (NRBA) of claim 1 to said subject.
29. A method of suppressing, inhibiting or reducing the amount of precancerous precursors of prostate adenocarcinoma lesions in a subject the method comprising administering a pharmaceutical composition comprising the nuclear receptor binding agent (NRBA) compound of claim 1 to said subject.
