The present invention is directed to a group of compounds which are 3β,17β-hydroxy steroids, and related steroidal structures. These compounds are aromatase inhibitors, and thus, regulate or inhibit the conversion of androgens to estrogens. These compounds may be utilized to treat conditions potentiated by the presence of estrogens. These compounds exhibit a slower onset of action and a longer half life relative to the 10-(2-alkynyl) steroidal aromatase inhibitors disclosed in U.S. Patent 4,322,416.
本发明涉及一组 3β,17β-羟基类
固醇及相关类
固醇结构的化合物。这些化合物是芳香化酶
抑制剂,因此可以调节或抑制雄激素向
雌激素的转化。这些化合物可用于治疗因
雌激素的存在而加重的病症。与美国专利 4,322,416 中公开的 10-(2-炔基)甾体芳香化酶
抑制剂相比,这些化合物的起效较慢,半衰期较长。
