Description:

Mifepristone is a synthetic steroid compound with both antiprogesterone and antiglucocorticoid properties. The compound is a 19-nor steroid with substitutions at positions C11 and C17 (17 beta-hydroxy-11 beta-[4-dimethylamino phenyl] 17 alpha-[1-propynyl]estra-4, 9-dien-3-one), which antagonizes cortisol action competitively at the receptor level.

Mifepristone is a progesterone receptor antagonist used as an abortifacient in the first months of pregnancy, and in smaller doses as an emergency contraceptive. It is also a powerful glucocorticoid receptor antagonist,

Mifepristone was the first antiprogestin to be developed and it has been evaluated extensively for its use as an abortifacient. The original target for the research group, however, was the discovery and development of compounds with antiglucocorticoid properties. These antiglucocorticoid properties are of great interest in the treatment of severe mood disorders and psychosis, although a review of published articles was inconclusive on their efficacy, and considered the use of these drugs in mood disorders at 'proof of concept' stage. It is on the World Health Organization's List of Essential Medicines.
