Ulipristal acetate

Ulipristal acetate, also known as CDB-2914, is a selective progesterone receptor modulator (SPRM) approved for contraception, and for uterine fibroid. As a SPRM, ulipristal acetate has partial agonistic as well as antagonistic effects on the progesterone receptor. It also binds to the glucocorticoid receptor, but is only a weak antiglucocorticoid relative to mifepristone, and has no relevant affinity to the estrogen, androgen and mineralocorticoid receptors.
