Progesterone Receptor Modulator

Asoprisnil (J867), a selective progesterone receptor modulator, exhibits mixed progesterone agonist and antagonist effects on various progesterone targeted tissues in animal and human.

Ulipristal (CDB 3236) is a selective progesterone receptor modulator (SPRM). Ulipristal binds to the progesteron receptor, thereby inhibiting PR-mediated gene expression, and interfering with progesterone activity in the reproductive system.

Vilaprisan is a selective progesterone receptor modulator (SPRM), which targets progesterone receptors. Vilaprisan can inhibit cell proliferation and stimulate apoptosis. Vilaprisan has oral efficacy and anti-proliferative activity against uterine leiomyoma (UF).

Trimegestone (RU 27987) is an orally active, selective progestogen and PR ligand, with an IC₅₀ of 7.6 nM for hPR, 4.4 nM for rabbit PR, and 3.3 nM for rat PR. Trimegestone induces Alkaline phosphatase activity. Trimegestone exhibits antiandrogenic activity (IC₅₀ = 303 nM). Trimegestone can be used in research related to menopausal symptoms and osteoporosis.

Telapristone acetate (CDB-4124) is a potent progesterone receptor (PR) modulator. Telapristone acetate inhibits the proliferation of ovarian cancer cells by inducing cell cycle arrest and apoptosis. Telapristone effectively inhibits the occurrence and development of spontaneous and chemically induced mammary tumors in rats. Telapristone acetate can be used for breast and ovarian cancer research.

EC 313 is a selective progesterone receptor modulator. EC 313 can dose dependently reduce the weight of fibroids. EC 313 can reduce the expression of ER and PR. EC 313 can be used for the study of uterine fibroids.

Brofoxine is a progesterone receptor modulator with anti-anxiety properties.

Asoprisnil ecamate (J 956) is an orally active antiprogestin, and can be used for contraception.

ORG 33628 is a potent and selective progesterone receptor modulator. ORG 33628 shows anti-progestational and anti-glucocorticoid activity. ORG 33628 shows ovulation-inhibitory activity. ORG 33628 has the potential for the research of breast and endometrium.

Ulipristal-d₃ (CDB-3236-d₃) is deuterium labeled Ulipristal. Ulipristal (CDB 3236) is a selective progesterone receptor modulator (SPRM). Ulipristal binds to the progesteron receptor, thereby inhibiting PR-mediated gene expression, and interfering with progesterone activity in the reproductive system.
