Abstract

Novel anti-estrogenic compounds are provided which are useful to treat a variety of disorders, particularly estrogen-dependent disorders. Preferred compounds have a 1,3,5-estratriene nucleus, and are substituted at the C-17 or C-11 position with a molecular moiety which renders the compounds effective to competitively block the binding of estrogen to its receptor. Particularly preferred compounds are 17-desoxy-1,3,5-estratrienes. Therapeutic methods and pharmaceutical compositions are provided as well.

Claims

1. A method for treating an individual with an estrogen-dependent disorder, comprising administering to the individual a therapeutically effective amount of a 17-desoxy-1,3,5(10)-estratriene containing the molecular moiety

2. The method of claim 1, wherein the estrogen-dependent disorder is breast cancer.

3. The method of claim 1, wherein the estrogen-dependent disorder is uterine cancer.

4. A method for treating an individual with an non-estrogen dependent cancer, comprising administering to the individual a therapeutically effective amount of a 17-desoxy-1,3,5(10)-estratriene containing the molecular moiety

5. The method of claim 4, wherein the cancer is multiple drug-resistant.

6. A method for increasing bone mass in the body of a mammalian individual, comprising administering to the individual an effective bone mass increasing amount of a 17-desoxy-1,3,5(10)-estratriene containing the molecular moiety

7. A method for inhibiting bone loss in the body of a mammalian individual, comprising administering to the individual an effective bone loss inhibiting amount of a 17-desoxy-1,3,5(10)-estratriene containing the molecular moiety

8. A method for lowering serum cholesterol in the body of a mammalian individual, comprising administering to the individual an effective serum cholesterol lowering amount of a 17-desoxy-1,3,5(10)-estratriene containing the molecular moiety

9. A method for inhibiting a pulmonary hypertensive disease, comprising administering to an individual in need of such treatment a therapeutically effective amount of a 17-desoxy-1,3,5(10)-estratriene containing the molecular moiety

10. A method for inhibiting skin atrophy, comprising prophylactically administering to a postmenopausal female individual an effective amount of a 17-desoxy-1,3,5(10)-estratriene containing the molecular moiety

11. A method for inhibiting vaginal atrophy, comprising prophylactically administering to a postmenopausal female individual an effective amount of a 17-desoxy-1,3,5(10)-estratriene containing the molecular moiety

12. A method for inhibiting an estrogen-dependent CNS disorder, comprising prophylactically administering to a postmenopausal female individual an effective amount of a 17-desoxy-1,3,5(10)-estratriene containing the molecular moiety

13. A method for treating osteoporosis in the body of a mammalian individual, comprising administering to the individual a therapeutically effective amount of a 17-desoxy-1,3,5(10)-estratriene containing the molecular moiety

14. A method for inhibiting a CNS disorder in a postmenopausal human female, comprising administering to the individual a therapeutically effective amount of a 17-desoxy-1,3,5(10)-estratriene containing the molecular moiety

15. A method for treating an individual with an estrogen-dependent disorder, comprising administering to the individual a therapeutically effective amount of a 17-desoxy-1,3,5(10)-estratriene containing the molecular moiety

16. The method of claim 15, wherein the estrogen-dependent disorder is breast cancer.

17. The method of claim 15, wherein the estrogen-dependent disorder is uterine cancer.

18. A method for treating an individual with an non-estrogen dependent cancer, comprising administering to the individual a therapeutically effective amount of a 17-desoxy-1,3,5(10)-estratriene containing the molecular moiety

19. The method of claim 18, wherein the cancer is multiple drug-resistant.

20. A method for increasing bone mass in the body of a mammalian individual, comprising administering to the individual an effective bone mass increasing amount of a 17-desoxy-1,3,5(10)-estratriene containing the molecular moiety
