Estrogen receptors (ERs) are members of a superfamily of ligand-modulated nuclear receptors, which have
been associated with an increased risk of cardiovascular diseases and breast cancer. Based on molecular docking studies,
1,4-dihydrothieno[3’,2’:5,6]thiopyrano[4,3-c]pyrazole-3-carboxamide derivatives as estrogen receptor inhibitors with a
new scaffold , have been synthesized and tested for the antitumor activity on the ER expressing (ER dependent) human
MCF-7 breast cancer cell line. According to the biological activity evaluation, compound 6a demonstrated the most potent
antiproliferative activity (relative inhibitory rate: 100%). Several of these compounds exhibited moderate antitumor activity
and worthy of further modification to obtain more potent anticancer candidate drugs.
雌激素受体(ERs)属于配体调节核受体超级家族,与心血管疾病和乳腺癌风险增加有关。基于分子对接研究,我们合成并测试了具有新型骨架的1,4-二氢噻吩并[3’,2’:5,6]噻吔并[4,3-c]吡唑-3-羧酰胺衍生物作为雌激素受体抑制剂,对表达ER的人类MCF-7乳腺癌细胞株的抗肿瘤活性。生物活性评估显示,化合物6a表现出最强的抗增殖活性(相对抑制率:100%)。多个化合物显示出中等抗肿瘤活性,值得进一步改造以获得更强的候选抗癌药物。
