    摘要: 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.

    摘要: 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. This method strongly inhibits changes in cells and tissues, such as lipid peroxidation and oxidation of low-density lipoprotein (LDL) cholesterol, triggered by reaction oxygen species, free oxygen radicals and other forms of radicals and thus reduces attendant irreversible membrane and endothelial damage.
