The invention provides novel compounds of the formula
or
wherein R1 is hydrogen, hydroxy, alkoxy of 1 to 4 carbon atoms, benzyloxy, allyloxy, 2,3-epoxypropoxy, 2,3-dihydroxypropoxy, methoxymethoxy, ethoxymethoxy, or
wherein one of R5 and R6 is hydrogen or R5 and R6 are alkyl groups of 1-4 carbon atoms which may be the same or different, or the -NR5R6 group stands for a nitrogen containing 5 to 7 membered heterocyclic radial and m is 1 or 2; R2 is an alkyl of 1 to 4 carbon atoms
wherein R7 has the same meanings as R1, except that R7 and R, cannot simultaneously be the same; R3 is an alkyl of 2 to 4 carbon atoms, cyclopentyl or hydroxy-cyclopentyl; R4 is hydrogen or hydroxy; and n is 0 to 3, provided that when R4 is hydrogen, then R2 and R3 are not simultaneously lower alkyl containing up to 4 carbon atoms, and their non-toxic pharmaceutically acceptable acid addition salts and esters and mixtures thereof. Processes for the preparation of these compounds are described, as are novel pharmaceutical compositions of the compounds or their salts. The compounds and their non-toxic salts exhibit valuable pharmacological properties as estrogenic, anti-estrogenic, progestanic and anti-tumour activity. Certain compounds of the group are useful as chemical intermediates for the preparation of pharmaceutically active compounds of the invention.
本发明提供了如下式子的新型化合物
或
其中 R1 是氢、羟基、1-4 个碳原子的烷氧基、苄氧基、烯丙基氧基、2,3-环氧丙氧基、2,3-二羟基丙氧基、甲氧基甲氧基、乙氧基甲氧基,或
其中 R5 和 R6 之一为氢,或 R5 和 R6 为 1-4 个碳原子的烷基,可以相同或不同,或 -NR5R6 基团代表含氮的 5-7 位杂环径向基团,且 m 为 1 或 2;R2 为 1-4 个碳原子的烷基
其中R7的含义与R1相同,但R7和R,不能同时相同;R3是2至4个碳原子的烷基、环戊基或羟基环戊基;R4是氢或羟基;n是0至3,但当R4是氢时,则R2和R3不能同时是含最多4个碳原子的低级烷基,以及它们的无毒药学上可接受的酸加成盐和酯及其混合物。本文介绍了这些化合物的制备方法,以及这些化合物或其盐的新型药物组合物。这些化合物及其无毒盐具有宝贵的药理特性,如雌激素活性、抗雌激素活性、孕激素活性和抗肿瘤活性。该组化合物中的某些化合物可用作制备本发明具有药用活性的化合物的化学中间体。
