摘要:
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.
摘要:
Disclosed are novel classes of anti-androgen including dihydrophenanthrene derivatives, their method of synthesis and their use in treating disorders associated with excessive androgenic activities.
摘要:
Described herein are compounds which either act as pure antiprogestins or as antiprogestins with partial agonistic activity and methods of treating cancer using such compounds.
摘要:
Novel 17.alpha.-aryl-steroids of the formula ##STR1## wherein R.sub.1 is alkyl of 1 to 3 carbon atoms, R.sub.2 is selected from the group consisting of hydrogen, alkyl of 1 to 12 carbon atoms and acyl of an organic carboxylic acid of 1 to 18 carbon atoms, R.sub.3 is aryl of 6 to 12 carbon atoms optionally substituted with at least one substituent selected from the group consisting of --OH, halogen, alkoxy and alkyl of 1 to 4 carbon atoms and --CF.sub.3, the dotted line in the B ring indicating an optional double bond in the 9(10)-position, and A and B are hydrogen and when there is a double bond in the 9(10)-position, A and B form a double bond in the 11(12) position or B is hydrogen and A is an 11.beta.-hydroxy having progestomimetic activity activity without androgenic activity and a process for their preparation and novel intermediates produced therein.
摘要:
The invention relates to novel ligands of the estrogen receptors α and β of general formula II, which are useful as an active substance of pharmaceuticals, for example pharmaceutical compositions useful for hormone replacement therapy, as well as for the treatment of tumors and inflammatory diseases. The invention also relates to a novel preparation method of these ligands comprising cyclotrimerization of ethynylestradiol with the appropriate diyne in an organic solvent. Further, the invention relates to pharmaceuticals comprising the novel compounds according to the invention.

摘要:
New non-estrogenic derivative compounds of estradiol, which have no estrogenic activity and comparatively high anti-oxidative activity, are disclosed. These new non-estrogenic derivative compounds are potentially useful as non-estrogenic antioxidants, especially for administration in post-menopausal women and in men. The compounds of the invention can also inhibit aromatase and sulfatase.
