Biological Activity

Mifepristone (RU-486) is a potent steroidal antagonist exhibiting subnanomolar affinity for progesterone receptors (PR IC₅₀ = 0.2 nM) and nanomolar activity against glucocorticoid receptors (GR IC₅₀ = 2.6 nM). This dual-receptor modulator competitively blocks endogenous hormone binding while inducing distinct conformational changes that prevent coactivator recruitment, demonstrating differential antagonism between PR and GR signaling pathways.
