 Context examples 

Mifepristone blocks the action of progesterone, a hormone that helps some cancers grow.

(Mifepristone, NCI Dictionary)

Mifepristone competitively binds to the progesterone receptor, resulting in inhibition of the effects of endogenous or exogenous progesterone.

(Mifepristone, NCI Thesaurus)

Also called mifepristone and RU 486.

(Mifeprex, NCI Dictionary)

Unlike many other antiprogestins such as mifepristone, this agent does not appear to convert to an agonist in the presence of protein kinase A (PKA) activators and shows high antiprogestagenic activity on both progesterone receptor (PR) isoforms PR-A and PR-B.
