Oestrogen related receptor α participated in the regulation of oxidative metabolism and mitochondrial biogenesis, and was overexpressed in many cancers including triple-negative breast cancer. A set of new ERRα inverse agonists based on p-nitrobenzenesulfonamide template were discovered and compound with high potent activity (IC = 0.80 μM) could significantly inhibit the transcription of ERRα-regulated target genes. By regulating the downstream signalling pathway, compound could suppress the migration and invasion of the ER-negative MDA-MB-231 cell line. Furthermore, compound demonstrated a significant growth suppression of breast cancer xenograft tumours (inhibition rate 23.58%). The docking results showed that compound could form hydrogen bonds with Glu331 and Arg372 in addition to its hydrophobic interaction with ligand-binding domain. Our data implied that compound represented a novel and effective ERRα inverse agonist, which had broad application prospects in the treatment of triple-negative breast cancer.
雌激素相关受体α(ERRα)参与氧化代谢和线粒体生物发生的调节,在许多癌症中过表达,包括三阴性乳腺癌。一组基于对硝基苯磺酰胺模板的新型 ERRα反向激动剂被发现,其中具有高活性的化合物 (IC = 0.80 μM)可显著抑制 ERRα 调节的靶基因的转录。通过调节下游信号通路,化合物 可抑制 ER 阴性 MDA-MB-231 细胞系的迁移和侵袭。此外,化合物 对乳腺癌异种移植瘤具有显著的生长抑制作用 (抑制率 23.58%)。对接结果表明,化合物 除了与配体结合域的疏水相互作用外,还可以与 Glu331 和 Arg372 形成氢键。我们的数据表明,化合物 代表了一种新型有效的 ERRα 反向激动剂,在治疗三阴性乳腺癌方面具有广阔的应用前景。
