improved tissue selectivity profiles compared with tamoxifen, optimal tissue selectivity has not yet been demonstrated. As such there is still a need for additional diversity and new chemical scaffolds to allow for exploration of improved tissue selectivity. Here, we describe the discovery of a novel phenanthrene scaffold for estrogen receptor ligands utilizing a ligand based de novo design approach. The
尽管与他莫昔芬相比,有许多雌激素受体拮抗剂具有改善的组织选择性,但尚未证明最佳组织选择性。因此,仍然需要额外的多样性和新的化学支架以探索改进的组织选择性。在这里,我们描述了利用基于配体的从头设计方法为雌激素受体配体开发的新型菲支架的发现。菲,12b,c,14b,c和15与人重组ERα的纳摩尔结合表明我们基于配体的从头设计方法是成功的。从基因转染测定中,12b,c,14b,c和15仅显示拮抗活性,没有可观察到的激动活性。烷基9 10-二氢菲16(大概是外消旋混合物)是比菲实质上更有效的ER粘合剂。它也仅表现出拮抗活性,并且在抑制雌二醇刺激的MCF-7细胞增殖方面是有效的。这些结果表明,作为潜在的选择性雌激素受体调节剂和/或纯抗雌激素,该菲(和9,10-二氢菲)支架值得进一步研究。
