The invention provides novel compounds of the formula: ##STR1## wherein n is 0 to 4, R.sub.1 and R.sub.2, which can be the same or different are H, OH, alkoxy of 1 to 4 carbon atoms, benzyloxy or methoxymethoxy; R.sub.3 is H, OH, halogen, alkoxy of 1 to 4 carbon atoms, benzyloxy, methoxymethoxy, 2,3-dihydroxypropoxy or ##STR2## wherein m is 1 or 2, R.sub.6 and R.sub.7, which can be the same or different are H or an alkyl group of 1 to 4 carbon atoms, or ##STR3## can form an N-containing three-, four-, five- or six-membered heterocyclic ring; R.sub.4 is OH, F, Cl, Br, I, mesyloxy, tosyloxy, alkylcarbonyloxy of 1 to 4 C-atoms, formyloxy or CH.sub.2 R.sub.4 is replaced by CHO; R.sub.5 is H or OH; or R.sub.4 and R.sub.5 together form an --O-- bridge between the carbon atoms to which they are attached, and their non-toxic pharmaceutically acceptable salts and esters and mixtures thereof. Processes for the preparation of these compounds are described, and also novel pharmaceutical compositions containing them. These compounds exhibit valuable pharmacological properties as estrogenic, anti-estrogenic, and progestanic agents. They are also effective against oestrogen-dependent tumors. Certain compounds are useful as chemical intermediates for the preparation of pharmacologically active compounds of the invention.
本发明提供了新的化合物,其化学式为:##STR1## 其中n为0至4,R.sub.1和R.sub.2可以相同也可以不同,分别为H,OH,1至4个碳原子的烷氧基,苄氧基或甲氧甲氧基;R.sub.3为H,OH,卤素,1至4个碳原子的烷氧基,苄氧基,甲氧甲氧基,2,3-二羟基丙氧基或##STR2## 其中m为1或2,R.sub.6和R.sub.7可以相同也可以不同,分别为H或1至4个碳原子的烷基,或##STR3## 可以形成含氮的三元、四元、五元或六元杂环;R.sub.4为OH,F,Cl,Br,I,甲磺氧基,对甲苯磺酰氧基,1至4个C原子的烷基羰氧基,甲酰氧基或CH.sub.2 R.sub.4被CHO取代;R.sub.5为H或OH;或R.sub.4和R.sub.5一起形成--O--桥,在它们附着的碳原子之间,以及它们的非毒性药用可接受的盐和酯及其混合物。本发明描述了制备这些化合物的工艺,以及含有它们的新型药物组合物。这些化合物具有有价值的药理作用,如雌激素、抗雌激素和孕激素作用。它们还对雌激素依赖性肿瘤有效。某些化合物可用作制备本发明药物活性化合物的化学中间体。
