potent compounds were 3-[2-(dimethylamino)ethoxy] -10-ethyl-11-(4-hydroxyphenyl)dibenzo[b,f]thiepin (7b) and 3-[2-(dimethylamino)ethoxy]-11-ethyl-12-(4-hydroxyphenyl)-5,6-dihydrodibenzo[a,e]-cyclooctene (7c), which had good binding (approximately 50% relative to estradiol) and good antiestrogenic activity (ca. one-half of the potency of tamoxifen, III). In this series, the O-bridged compound was the
桥接基团O,S,CH2CH2和SCH2用于生产一系列26个三环三芳基乙烯。在竞争结合试验中测量了它们与大鼠子宫雌激素受体的体外结合。大鼠的抗生育和子宫营养测试表明存在抗雌激素活性。最有趣的系列有一个基本侧链,最有效的化合物是3- [2-(二甲基氨基)乙氧基] -10-乙基-11-(4-羟基苯基)二苯并[b,f]噻吩(7b)和3 -[2-(二甲基氨基)乙氧基] -11-乙基-12-(4-羟基苯基)-5,6-二氢二苯并[a,e]-环辛烯(7c),具有良好的结合力(相对于雌二醇约为50%)和良好的抗雌激素活性(约为他莫昔芬(Ⅲ)药效的一半)。在本系列中,O桥化合物的活性最低,这是用二苯并二甲苯环系统的平面度来解释的。在某些化合物中发现了镇静活性。
