of them showed better antiproliferative efficacy in MCF-7 cell lines with IC50 up to 3.7 μM. In vivo experiments in a MCF-7 breast cancer model in Balb/c nude mice indicated that compound 26a was more potent than tamoxifen. Exploration of the compliancy of the structure against ER specificity utilizing these types of isomeric three-dimensional ligands indicated that one enantiomer had much better biological
在这项工作中,我们通过将已知的NF-κB抑制剂白藜芦醇(RES)掺入到小鼠体内,开发了一个具有双重抑制活性的新型OBHS-RES杂合化合物的小型文库,该化合物具有针对雌激素受体α(ERα)和NF-κB的双重抑制活性。雌激素受体(ER)的特权间接拮抗结构基序(OBHS,氧杂环庚烯磺酸盐)。OBHS-RES偶联物可以很好地与ER结合,并表现出显着的ERα拮抗活性,并且在巨噬细胞RAW 264.7细胞中也表现出出色的NO抑制作用。用4-羟基他相比,它们中的一些显示在MCF-7细胞系IC更好的抗增殖功效50达3.7μM。在Balb / c裸鼠的MCF-7乳腺癌模型中进行的体内实验表明,化合物26a比他莫昔芬更有效。利用这些类型的异构体三维配体探索结构对内质网特异性的顺应性表明,一种对映异构体具有比另一种对映异构体更好的生物学活性。
