measured and correlated with the effects of these drugs on cell proliferation kinetics. Affinities for ER and AEBS were highly correlated, illustrating that vinyl substituents influence binding to ER and AEBS in a parallel manner. All compounds except 7 had biphasic effects on cell proliferation kinetics, indicating the presence of at least two distinct mechanisms by which hydroxytriarylethylenes inhibit
合成了一系列与4-羟基克罗米芬(2)有关的三芳基乙烯化合物,其中乙烯基Cl取代基被乙基(5),Br(6),H(7),CN(8)或NO2(9)取代基取代以促进合成非甾体类抗雌激素分子作用的研究。测量了这些化合物对MCF 7人乳腺癌细胞中雌激素受体(ER)和抗雌激素结合位点(AEBS)的相对结合亲和力,并与这些药物对细胞增殖动力学的影响相关。ER和AEBS的亲和力高度相关,说明乙烯基取代基以平行方式影响与ER和AEBS的结合。除7种化合物外,所有化合物均对细胞增殖动力学具有双相影响,表明存在至少两种不同的机制,羟基三芳基乙烯通过这些机制抑制乳腺癌细胞增殖。在10(-10)-10(-8)M的浓度范围内,细胞增殖被抑制60-70%,这些作用是雌激素可逆的,并且生长抑制的程度为Cl大于Et大于Br大于NO2大于CN大于H,这与ER的亲和力顺序平行。在10(-8)和10(-6)M之间没有对细胞生长的进
