  • Patent number: 7199115
    Abstract: New 17?-fluorosteroid compounds of formula (I) are disclosed: wherein R1 denotes H or methyl; R2 and R3 each denote H, Cl or methyl; and either a double bond or a single bond is present between C-6 and C-7 and also C-9 and C-10 of the steroid ring system respectively. These compounds have an activity profile with hybrid character so that they act as inhibitors for 5?-reductase and as high potency gestagens. Pharmaceutical compositions containing them are disclosed. They are suitable for treatment of conditions, which are caused by high levels of androgen in organs and tissues. These new compounds can be used in combination with other hormonal substances, such as estrogens, testosterone and other androgens, as contraceptives and for other applications.

  • Patent number: 7186728
    Abstract: 17-methylene-4-azasteroid compounds of formula I: wherein R20 denotes fluoro, chloro or bromo R20a denotes hydrogen, R10 and R4 each denote a hydrogen atom or a methyl group, and R1 and R2 each denote a hydrogen atom or together denote an additional bond, are useful for treating diseases or conditions caused by excessive androgen levels, such as acne, prostate diseases, alopecia and hirsutism, as well as gynecological conditions. Methods of synthesizing the new 17-methylene-4-azasteroid compounds are described.

  • Patent number: 6855836
    Abstract: The invention relates to 17-methylene steroids, process for their production and pharmaceutical compositions that contain these compounds. The compounds according to the invention have a hybrid-type profile of action in the sense that they act as inhibitors of 5?-reductase and simultaneously as gestagens. They are therefore suitable for treating diseases that are the result of elevated androgen levels in certain organs and tissues in men and women. Together with other hormonal substances, such as an estrogen, testosterone or a strong androgen, the compounds according to the invention are suitable as contraceptive agents for women and for men.

  • Patent number: 4598072
    Abstract: A combination of an aromatase-inhibitor and an antiandrogen in a weight ratio of aromatase-inhibitor to antiandrogen of 20:1 to 1:1 is useful in a method of prophylaxis and/or of treatment by therapy of prostatic hyperplasia. The aromatase-inhibitor is, for example, testolactone and the antiandrogen is, for example, cyproterone acetate.
