appending zinc binding groups to the 4-hydroxystilbene core of 4-hydroxytamoxifen. The resulting hybrids were fully bifunctional, and displayed high nanomolar to low micromolar IC50 values against both the estrogen receptor α (ERα) and HDACs in vitro and in cell-based assays. The hybrids were antiproliferative against ER+ MCF-7 breast cancer cells, with hybrid 28b possessing an improved activity profile
通过将锌结合基团附加到 4-羟基三苯氧胺的 4-羟基二苯乙烯核心,设计了混合抗雌激素/组蛋白脱乙酰酶 (HDAC) 抑制剂。由此产生的杂交体是完全双功能的,并在体外和基于细胞的测定中显示出针对雌激素受体α(ERα)和 HDAC 的高纳摩尔至低微摩尔 IC 50值。杂交体对 ER+ MCF-7 乳腺癌细胞具有抗增殖作用,与4-羟基三苯氧胺或 SAHA 相比,杂交体28b具有改进的活性谱。Hybrid 28b显示出反映 ERα 和 HDAC 抑制的基因表达模式。
