  • 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: 5977096
    Abstract: Novel substituted steroid compounds are disclosed which are more effective than known radical-trapping agents in methods of prophylaxis and therapy of radical-mediated cell damage and of treatment of diseases due to radical-mediated cell damage. The novel substituted steroid compounds can be made from steroids having an estrane, androstane, pregnane or cholestane basic skeleton and have a radical-attracting aromatic substituent of the general formula --(CH.sub.2).sub.n X, or .dbd.CH--(CH.sub.2).sub.m X at the 17 or 6 position of the steroid nucleus, wherein X=Y, OY, SY, SeY or NHY; n=0 to 5; m=n-1 and Y is a phenyl group having five substituents A, B, C, D and E, wherein A to E is independently H, alkyl, Oalkyl, Oacyl, OH, or one of the substituents B, C or D is NR.sub.2 wherein R=alkyl and each of the other substituents is hydrogen. Pharmaceutical compositions containing the novel substituted steroid compounds and methods of making them are also part of the invention.

  • Patent number: 5866559
    Abstract: The 17.alpha.-cyanomethylestra-4,9-diene derivative compounds are of formula I: ##STR1## wherein R.sub.1 is an alkyl group having from 1 to 2 carbon atoms; R.sub.2 is an alkyl group with 1 to 10 carbon atoms, an acyl group with 1 to 10 carbon atoms or a trialkylsilyl group; and R.sub.3 is an oxygen atom or a R--O--N group, wherein R is a hydrogen atom, an acyl group with 1 to 10 carbon atoms, an alkyl group with 1 to 10 carbon atoms, a sulfamoyl group, an alkylsilyl group or a trialkylsilyl group. These compounds, particularly in combination with at least one suitable estrogen, are suitable for treatment of endometrioses or gestagen-dependent tumors and for hormonal contraception and climacteric hormone replacement therapy (HRT). Processes for making the new steroids are described as well as methods of making the pharmaceutical compositions containing them.
