the resulting cis- and trans-stilbene derivatives, and ether cleavage with BBr3. The cis-stilbenes were catalytically hydrogenated to give meso-1,1,1,4,4,4-hexafluoro-2,3-bis(4- and 3-hydroxyphenyl)butanes 6 and 8. Compounds 2, 4, 6, and 8 showed 2- to 10-fold increased binding affinities for the estradiol receptor (E2R) and enhanced estrogenicity in the uterine weight test of the immature mouse compared
通过对甲氧基取代的α,α,α进行还原偶联(TiCl4 / Zn /吡啶),制备反式1,2-双(三氟甲基)-1,2-双(4-和3-羟基苯基)乙烯2和4。 -三氟苯乙酮,分离所得顺式和反式-二苯乙烯衍生物,并用BBr3进行醚裂解。顺式-苯乙烯基苯甲酸酯被催化氢化,得到内消旋1,1,1,1,4,4,4-六氟-2,3-双(4-和3-羟基苯基)丁烷6和8。化合物2、4、6、6与未氟化类似物相比,图8和图8在未成熟小鼠的子宫重量测试中显示出对雌二醇受体(E2R)的结合亲和力提高了2到10倍,并且雌激素性增强。化合物8表现出对雌酮刺激的子宫生长的46%抑制。使用可移植物评估抗肿瘤活性,BD2F1小鼠的激素依赖性MXT乳腺肿瘤。所有化合物均显示出与其RBA值相对应的肿瘤生长抑制活性。最有趣的化合物8导致DMBA诱导的Sprague-Dawley大鼠激素依赖性乳腺癌的肿瘤生长受到显着抑制。
