A series of structurally simple bibenzyl-diol and stilbene-diol core molecules, structural analogs of the well-known hexestrol and diethylstilbestrol non-steroidal estrogens, were prepared and evaluated as estrogen receptor (ER) subtype-selective ligands. Analysis of their ERα and ERβ binding showed that certain substitution patterns engendered binding affinities that were >100-fold selective for ERβ
一系列结构简单的联苄二醇和芪二醇核心分子,众所周知的己雌酚和己烯雌酚非甾体雌激素的结构类似物,被制备并评估为雌激素受体 (ER) 亚型选择性配体。对它们的 ERα 和 ERβ 结合的分析表明,某些取代模式产生了对 ERβ 具有 >100 倍选择性的结合亲和力。当在基于细胞的基因转录测定中进一步研究时,一些分子显示出类似的高相对转录效力选择性,有利于 ERβ。有趣的是,最具 ERβ 选择性的分子是那些在内部碳原子之一上带有非极性取代基的分子。这些化合物应该是确定 ERβ 生理作用的有用探针,
