decreased the RBA values. In the immature mouse assay, 15 (R = CH3) and 19 (R = CH2CF3) had the highest uterotrophic activity. There was no correlation between receptor affinity and estrogenic properties. Compounds 14 (R = H), 17 (R = n-C3H7), the ethane 20, and the oxirane 21 had some antiuterotrophic activity in a low dosage. The MXT tumor was best inhibited by compounds 15 (R = CH3), 16 (R = C2H5), and
为了研究烷基侧链的影响,合成了在位置2处被H,CH3,C2H5,n-C3H7,i-C3H7或CH2CF3取代的1,1-双(4-乙酰氧基苯基)-2-苯基乙烯对雌二醇受体的亲和力,雌激素和抗雌激素特性以及对小鼠激素依赖性MXT乳腺癌的抑制作用。此外,将1,1-双(4-乙酰氧基苯基)-2-苯基丁-1-烯的双键氢化或环氧化,得到相应的乙烷和环氧乙烷衍生物。化合物14(R = H),15(R = CH3)和16(R = C2H5)具有最佳结合亲和力。延长侧链,氢化或环氧化会降低RBA值。在未成熟的小鼠实验中,15(R = CH3)和19(R = CH2CF3)具有最高的子宫营养活性。受体亲和力和雌激素特性之间没有相关性。化合物14(R = H),化合物17(R = n-C3H7),乙烷20和环氧乙烷21在低剂量下具有一定的抗子宫营养作用。在实验结束时确定的化合物15(R = CH3),16(R = C2H5)和18(R
