Abstract: Described are novel equilenin derivatives of general formula I 1

Abstract: Described are novel equilenin derivatives of general formula I methods for producing the same and medicaments containing these compounds. The new compounds have antioxidative activity and are usable for geroprophylaxis in women and men.

Abstract: 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.

Abstract: This invention describes 17&agr;-hydroxy-4-androstene-3-one and its derivatives of the general formula I a method for producing these compounds and pharmaceuticals containing these compounds. The compounds according to the invention can be used for regulating spermatogenesis and for hormone replacement therapy in males by stimulating the inhibin-B secretion by the Sertoli cells. The increased inhibin-B concentration suppresses spermatogenesis in the testicles as it inhibits excretion by the hypophysis of follicle-stimulating hormone (FSH) that is essential in spermatogenesis.

Abstract: Pharmaceutical preparations containing selected steroid compounds and methods of treating estrogen deficiency in the central nervous system (CNS) without influencing other organs or systems are described. These steroids have selective neurotropic estrogen-like transcription action in contrast to the systemically acting natural and synthetic estrogen compounds, such as 17&agr;-estradiol. The selected steroids surprisingly have a selective influence on the transcription estrogen-dependent gene in the CNS and cause changes of physiological parameters as well as CNS-specific transcription effects in the dosages used with no biological effects in reproductive system tissues. They have CNS specific transcription effects at those dosages at which neither 17 &bgr;-estradiol nor 17&agr;-estradiol had any action and the transcription estrogen-dependent gene in the CNS is not influenced by secondarily formed 17&bgr;-estradiol.

Abstract: The method of prophylaxis and therapy of radical-mediated cell damage includes administering an effective amount of at least one steroid and at least one pharmaceutical adjuvant to a human being. The at least one steroid is selected from the group consisting of ent-estradiol, 17&agr;-estradiol, 8-dehydro-estradiol, 8-dehydro-17&agr;-estradiol, 8(14)-dehydroestradiol, 6,8-didehydro-17&agr;-estradiol, 6-dehydroestriol, 9(11)-dehydroestriol, 20-hydroxymethyl-3-hydroxy-19-norpregna-1,3,5(10)-triene, 14&agr;, 15&agr;-methylene-8-dehydroestradiol, 14&agr;, 15&agr;-methylene-estradiol, 2-hydroxy-estradiol-3-methyl ether, 3-hydroxy-1,3,5(10)-estratriene-17S-spirooxirane, 3-hydroxy-1,3,5(10),9(11)-estratetraene-17S-spirooxirane, and 14&bgr;,15&bgr;-methylene-8-dehydroestradiol.
