The invention relates to new 11-arylsteroid compounds, having a strong antiprogestin and a weak or nonexistent antiglucocorticoid activity, to processes for preparing said compounds and also to pharmaceutical preparations which contain these derivatives as active constituent, characterized in that said steroids have the following formula:
in which
R₁ is an aryl group with a -X
group as substituent, X and Y each being separately H or a (1-4 C) hydrocarbyl group or together a (2-6 C) hydrocarbyl group which forms a 3- to 7-membered ring together with the nitrogen atom;
R₂ is hydrogen, hydroxyl, an acyloxy or an alkoxy group or a saturated or unsaturated hydrocarbyl group containing 1-8 carbon atoms, which hydrocarbyl group is provided with at least one hydroxyl, oxo, azido, cyano and/or halogen group;
R₃ is a hydroxyl, an acyloxy or an alkoxy group or an acyl group optionally substituted by a hydroxyl, alkoxy, acyloxy or halogen group; or R₂ and R₃ together form a ring system, with the proviso that if R₃ is hydroxyl, R₂ is not hydrogen or hydroxyl; and
R₄ is a methyl or ethyl group;
and the α- and β-bonds are indicated by dashed (---) and wedged () lines respectively.
本发明涉及具有较强的抗孕激素活性和较弱或不存在的抗糖皮质激素活性的新的 11-芳基类固醇化合物,涉及制备上述化合物的工艺,还涉及含有这些衍生物作为活性成分的药物制剂,其特征在于上述类固醇具有下式:
其中
R₁ 是芳基,带有 -X
基团为取代基的芳基,X 和 Y 分别为 H 或(1-4 C)烃基或(2-6 C)烃基,它们与氮原子一起构成 3-7 元环;
R₂ 是氢、羟基、酰氧基或烷氧基或含有 1-8 个碳原子的饱和或不饱和烃基,该烃基上至少含有一个羟基、氧代、叠氮、氰基和/或卤素基团;
R₃ 是羟基、酰氧基或烷氧基,或任选被羟基、烷氧基、酰氧基或卤素基团取代的酰基;或 R₂ 和 R₃ 共同形成一个环系统,但如果 R₃ 是羟基,则 R₂ 不是氢或羟基;以及
R₄ 是甲基或乙基;
α键和β键分别用虚线(---)和楔形线()表示。
