##STR1## wherein n is 0 to 4, R.sub.1 and R.sub.2, which can be the same or different, are H or OH; R.sub.3 is --O--(CH.sub.2).sub.m --CH.sub.2 --NR.sub.6 R.sub.7 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 --NR.sub.6 R.sub.7 can form a pyrrolidinyl group; and R.sub.4 is halogen, and their non-toxic pharmaceutically acceptable salts and phenolic esters of aliphatic or aromatic carboxylic acids, acid anhydrides or acid chlorides thereof are disclosed. These compounds exhibit valuable pharmacological properties as estrogenic, anti-estrogenic, and progestanic agents. They show activity against oestrogen-dependent tumors.
其中n为0至4,R.sub.1和R.sub.2可以相同或不同,为H或OH;R.sub.3为--O--(CH.sub.2).sub.m --CH.sub.2 --NR.sub.6 R.sub.7,其中m为1或2,R.sub.6和R.sub.7可以相同或不同,为1至4个碳原子的烷基或--NR.sub.6 R.sub.7可以形成吡咯烷基;而R.sub.4为卤素。这些化合物及其无毒的药用可接受盐和脂肪族或芳香族羧酸、酸酐或酸氯化物的酚酯被揭示出来。这些化合物表现出有价值的药理作用,如雌激素、抗雌激素和孕激素作用。它们对雌激素依赖性肿瘤具有活性。
