The invention describes new compounds as pharmaceutical active ingredients, which have in vitro a higher affinity to estrogen receptor preparations from rat prostates than to estrogen receptor preparations from rat uteri and in vivo a preferential action on bone rather than the uterus, their production, their therapeutic use and pharmaceutical dispensing forms that contain the new compounds.
The new compounds are 16α- and 16β-hydroxy-estra-1,3,5(10)-estratrienes, which carry additional substituents on the steroid skeleton and can have one or more additional double bonds in the B-, C- and/or D-rings.
该发明描述了新的化合物作为药物活性成分,它们在体外与来自大鼠前列腺的
雌激素受体制剂的亲和力高于与来自大鼠子宫的
雌激素受体制剂的亲和力,并在体内对骨骼而非子宫具有优先作用,还包括它们的生产、治疗用途以及含有新化合物的药物分配形式。新化合物为16α-和16β-羟基-雌-1,3,5(10)-
三烯,其携带类
固醇骨架上的额外取代基,并且可以在B,C和/或D环中具有一个或多个额外的双键。
