Ligands which selectively activate only one of the estrogen receptors, ERα or ERβ, are current pharmaceutical targets. Previously, we have reported on substituted cis A-CD ligands in which the B-ring of the steroidal structure has been removed and cis refers the stereochemistry of the CD ring junction as compared to trans in estradiol. These compounds often showed good potency and selectivity for ERβ
仅选择性激活一种雌激素受体 ERα 或 ERβ 的配体是当前的药物靶点。以前,我们报道了取代的顺式A-CD 配体,其中甾体结构的 B 环已被去除,顺式是指与雌二醇中的反式相比,CD 环连接的立体化学。这些化合物通常对 ERβ 表现出良好的效力和选择性。在这里,我们报告了类似系列的反式A-CD 配体的合成和结合亲和力,并将它们与顺式系列进行了比较。与直觉相反,反式A-CD 配体在结构上与天然配体雌二醇更密切相关,与它们的顺式配体相比,显示出较弱的结合和较低的 β 选择性。
