Mifepristone is a progesterone receptor antagonist with antiglucocorticoid and antiandrogen properties. In neuroscience, it is investigated for its role in modulating stress responses and glucocorticoid signaling. Its high affinity for glucocorticoid receptors positions it as a potential modulator of neuroendocrine and neuroinflammatory pathways.
