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 8&bgr;-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.
本发明描述了新的8&bgr;-取代的环雌
三烯通式I,其中R2、R3、R6、R6'、R7、R7'、R9、R11、R11'、R12、R14、R15、R15'、R16、R16'、R17和R17'的含义如说明书所示,而R8表示直链或支链,可选部分或完全卤代的含有最多5个碳原子的烷基或烯基基团,一个
乙炔基或丙-1-炔基,作为药物活性成分,具有比大鼠子宫
雌激素受体制备更高的亲和力,而且在体内更倾向于对骨骼而不是子宫产生优先作用和/或对5HT2a受体和5HT2a转运体的表达刺激作用显著,本发明还描述了这些化合物的生产、治疗用途和含有新化合物的药物配制形式。本发明还描述了这些化合物用于治疗
雌激素缺乏引起的疾病和病症,以及在化合物的总结构中使用8&bgr;-取代的环雌
三烯结构部分,以使其更倾向于对骨骼而不是子宫产生
雌激素作用的解离。
