The invention relates to 11-aryl steroid derivatives, having the structure
wherein:
R₁ is a homocyclic or heterocyclic aryl group having one of the following substituents: an optionally saturated or unsaturated, branched or unbranched hydrocarbon radical containing 1-10 carbon atoms, the hydrocarbon radical being optionally provided with a hydroxyimino, oxo and/or hydroxyl group, or a
group, where X and Y are each separately H or a hydrocarbon (1-4 C) radical or are together a hydrocarbon (2-6 C) radical;
R₂ is an alkyl group containing 1-4 carbon atoms;
R₃ is H, OH, a saturated or unsaturated hydrocarbon radical containing 1-8 carbon atoms, optionally provided with one or more hydroxyl, azido, nitrile, oxo and/or halogen groups, or is a (1-18 C) acyloxy or (2-8 C) alkoxyalkyl or (1-18 C) acyl or (1-12 C) alkoxy group;
R₄ is H, OH, a saturated or unsaturated hydrocarbon grup containing 1-8 carbon atoms, optionally provided with one or more hydroxyl, azido, nitrile, oxo and/or halogen groups, or is a (1-18 C) acyloxy or (2-8 C) alkoxyalkyl or (1-18 C) acyl or (1-12 C) alkoxy group; or R₃ and R₄ together form a ring system or an alkylidene group having 1-6 carbon atoms and the dotted line represents an optional bond between the carbon atoms 16 and 17 of the steroid skeleton, with the proviso that R₃ or R₄ is absent if said bond between said carbon atoms 16 and 17 is present
and to processes for their preparation and to pharmaceuticals comprising these compounds.
these compounds exhibit a strong anti-progestinic activity and a weak or non-existent anti-glucocorticoid activity.
