New 17α-fluorosteroid compounds of formula (I) are disclosed:
wherein R
1
denotes H or methyl; R
2
and R
3
each denote H, Cl or methyl; and either a double bond or a single bond is present between C-6 and C-7 and also C-9 and C-10 of the steroid ring system respectively. These compounds have an activity profile with hybrid character so that they act as inhibitors for 5α-reductase and as high potency gestagens. Pharmaceutical compositions containing them are disclosed. They are suitable for treatment of conditions, which are caused by high levels of androgen in organs and tissues. These new compounds can be used in combination with other hormonal substances, such as estrogens, testosterone and other androgens, as contraceptives and for other applications.
本发明公开了新的式(I)17α-类
固醇化合物:
其中 R
1
表示 H 或甲基;R
2
和 R
3
分别表示 H、Cl 或甲基;类
固醇环系统的 C-6 和 C-7 之间以及 C-9 和 C-10 之间存在双键或单键。这些化合物具有混合性质的活性特征,因此它们既是 5α 还原酶的
抑制剂,又是高效的
雌激素。本研究还公开了含有这些化合物的药物组合物。它们适用于治疗因器官和组织中雄激素
水平过高而引起的疾病。这些新化合物可与其他激素物质(如
雌激素、
睾酮和其他雄激素)结合使用,作为
避孕药和用于其他用途。
