This invention describes the new 8beta-substituted estratrienes of general formula I in which R<SUP>2</SUP>, R<SUP>3</SUP>, R<SUP>6</SUP>, R<SUP>6'</SUP>, R<SUP>7</SUP>, R<SUP>7'</SUP>, R<SUP>9</SUP>, R<SUP>11</SUP>, R<SUP>11'</SUP>, R<SUP>12</SUP>, R<SUP>14</SUP>, R<SUP>15</SUP>, R<SUP>15'</SUP>, R<SUP>16</SUP>, R<SUP>16'</SUP>, R<SUP>17</SUP>, R<SUP>17'</SUP> have the meanings that are indicated in the description, and R<SUP>8 </SUP>means a straight-chain or branched-chain, optionally partially or completely halogenated alkyl or alkenyl radical with up to 5 carbon atoms, an ethinyl- or prop-1-inyl radical, as pharmaceutical active ingredients that have in vitro a higher affinity to estrogen receptor preparations of rat prostates than to estrogen receptor preparations of rat uteri and in vivo preferably a preferential action on bone rather than the uterus and/or a pronounced action with respect to stimulation of the expression of 5HT2a-receptors and 5HT2a-transporters, their production, their therapeutic use and pharmaceutical dispensing forms that contain the new compounds. The invention also describes the use of these compounds for treatment of estrogen-deficiency-induced diseases and conditions as well as the use of an 8beta-substituted estratriene structural part in the total structures of compounds that have a dissociation in favor of their estrogenic action on bones rather than the uterus. |
