RJW100 是一种有效的肝受体同源物 1 (LRH-1，NR5A2) 和类固醇生成因子-1 (SF-1，NR5A1) 激动剂，pEC50 分别为 6.6 和 7.5。RJW100 还可有效激活 miR-200c (miRNA-200c, microRNA-200c) 启动子。
RJW100 is a potent liver receptor homolog 1 (LRH-1, NR5A2) and steroidogenic factor-1 (SF-1, NR5A1) agonist with pEC50s of 6.6 and 7.5, respectively[1]. RJW100 also causes strong activation of the miR-200c (miRNA-200c, microRNA-200c) promoter[2].
RJW100 (compound 24-exo) treatment induces a significant dose-dependent increase in small/short heterodimer partner (SHP) transcripts beginning at 5 µM[1].RJW100 (compound 24-exo) clearly displaces the bound PIP2 phospholipid from SF-1 almost completely at 1 µM[1].Using hLRH-1 LBD alone that had not been complexed with any phospholipids, the result shows a clear dose-dependent shift in hLRH-1 LBD (ligand binding domain) native PAGE migration upon RJW100 (compound 24-exo; 0-100 µM) binding[1].RJW100 causes strong activation of the miR-200c promoter and exhibits strong ability to downregulate ZEB1 and ZEB2 proteins[2].
