      Mifepristone(RU-38486; RU486) is a progesterone receptor antagonist(IC50= 0.2 nM) used as an abortifacient in the first months of pregnancy, and in smaller doses as an emergency contraceptive.;IC50 Value: 0.2 nM (Progesterone receptor); 2.6 nM (Glucocorticoid receptor) [1];Target: Progesterone receptorMifepristone is a synthetic steroid compound used as a pharmaceutical. It is a progesterone receptor antagonist used as an abortifacient in the first months of pregnancy, and in smaller doses as an emergency contraceptive. Mifepristone is also a powerful glucocorticoid receptor antagonist, and has occasionally been used in refractory Cushing's Syndrome.;In vitro: Mifepristone had no effect onHeLa cell proliferation inhibition rate during 24 and 48 hours (p > 0.05). Mifepristone at low concentrations (< or = 10 micromol/l) combined withcisplatin can significantly enhance the inhibitory effect of cisplatin on HeLa cell line [2].
