The invention relates to novel Δ¹⁴-16α,17-dihydroxy-pregnane-16,17-cyclic aldehyde acetal and -cyclic ketone ketal derivatives of general formula (I),
wherein
A stands for hydrogen or hydroxyl group;
X stands for hydrogen or halogen with the proviso that if A is hydrogen, then X also means hydrogen;
R stands for hydrogen,benzoyl or C₁⁻₈alkanoyl group;
R¹ and R², which are the same or different, stand for hydrogen or a C₁⁻₄alkyl group; or one of R¹ and R² is hydrogen and the other is phenyl group; or R¹ and R² together form a C₄⁻₅alkylene group;
--- means a single or double bond between two adjacent carbon atoms,
as well as pharmaceutical compositions containing these compounds and a process for their preparation.
The compounds of general formula (I) possess a very strong antiinflammatory effect and only week harmful side effect. Thus, they can be used as active ingredients of antiinflammatory pharmaceutical compositions being useful in the therapy.
本发明涉及通式(I)的新型Δ¹⁴-16α,17-二羟基
孕甾烷-16,17-环醛
缩醛和-环酮
缩酮衍
生物、
其中
A 代表氢或羟基;
X 代表氢或卤素,但如果 A 是氢,则 X 也代表氢;
R 代表氢、苯甲酰基或 C₁-₈ 烷酰基;
R¹ 和 R²(相同或不同)代表氢或 C₁-₄ 烷基;或 R¹ 和 R² 中的一个是氢,另一个是苯基;或 R¹ 和 R² 共同形成 C₄-₅ 烯基;
----指两个相邻碳原子之间的单键或双键、
以及含有这些化合物的药物组合物及其制备方法。
通式(I)的化合物具有很强的抗炎作用,只有一周的有害副作用。因此,它们可用作抗炎药物组合物的活性成分,在治疗中非常有用。
