converted into the corresponding furans, but formation of the thiophenes and pyrroles from the more highly substituted 1,4-diones was problematical. Of the systems investigated, the tetrasubstituted furans proved to be most interesting. They were ER alpha binding- and potency-selective agents, with the triphenolic 3-alkyl-2,4,5-tris(4-hydroxyphenyl)furans (15a-d) displaying generally higher subtype binding
多种非甾体系统可以充当雌激素受体(ER)的配体,在某些情况下,它们对两种ER亚型之一ERα或ERβ表现出选择性。我们为雌激素受体准备了一系列基于杂环的(呋喃,噻吩和吡咯)配体,并评估了它们作为ER配体的行为。开发了醛烯酮共轭加成方法和烯醇烷基化方法以制备分别为三取代和四取代系统的前体的1,4-二酮系统。所有的二酮都容易转化为相应的呋喃,但是由取代程度更高的1,4-二酮形成噻吩和吡咯是有问题的。在研究的系统中,四取代的呋喃被证明是最有趣的。它们是ERα结合和效能选择剂,三酚3-烷基-2,4,5-三(4-羟苯基)呋喃(15a-d)通常显示出比双酚类似物(15f-一世)。ERα的结合选择性高达50-70倍,转录激活研究表明,该系列的几个成员是ERα选择性激动剂,具有最佳化合物[3-ethyl-2,4,5-tris(4 -羟基苯基)呋喃,15b]对ER alpha具有完全的转录活性,而对ER be
