Progesterone Receptor

Medroxyprogesterone Acetate (Farlutin) is a synthetic progestin that is derived from 17-hydroxyprogesterone. It is a long-acting contraceptive that is effective both orally or by intramuscular injection and has also been used to treat breast and endometrial neoplasms.

Ulipristal acetate (CDB-2914) is an orally bioavailable, acetate salt of ulipristal, a selective progesterone receptor modulator with anti-progesterone activity. Ulipristal binds to the progesterone receptor (PR), thereby inhibiting PR-mediated gene expression, and interfering with progesterone activity in the reproductive system. As a result, this agent may suppress the growth of uterine leiomyomatosis. Furthermore, by inhibiting or delaying ovulation and effecting endometrial tissue, ulipristal can be used as an emergency contraception.

Mifepristone (C-1073) is a Progestin Antagonist. The mechanism of action of mifepristone is as a Progestational Hormone Receptor Antagonist.

Levonorgestrel (D-Norgestrel) is a Progestin and Progestin-containing Intrauterine Device. The physiologic effect of levonorgestrel is by means of Inhibit Ovum Fertilization.

Vilaprisan (BAY 1002670) is a novel orally available and selective progesterone receptor modulator (SPRM) with antiproliferative activity against uterine fibroids (UF) and can be used for the study of uterine fibroids.

Benzonitrile, 4-[[5-cyclopropyl-3-methyl-1-[(methylsulfonyl)methyl]-1H-pyrazol-4-yl]oxy]-2,6-dimethyl- is a progesterone receptor antagonist with antiprogestin effects.

PF-02413873 is a competitive antagonist of nonsteroidal progesterone receptor with a Ki of 2.6 nM. PF-02413873 can be used in studies about the treatment of gynecological conditions such as endometriosis.

Progesterone (Pregn-4-ene-3,20-dione) is the major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production.

Ethynodiol diacetate (Ethynodiol acetate) is a synthetic progestational hormone used alone or in combination with estrogens as an oral contraceptive.

Dydrogesterone is a potent progestogen which can be used in progesterone deficiency studies.

Gestodene (WL 70) is a progestogen hormonal contraceptive.

Desogestrel (Cerazette) is a synthetic progestational hormone used often as the progestogenic component of combined oral contraceptive agents.

Megestrol acetate (BDH1298) is a progestogen with actions and uses similar to those of the progestogens in general. Megestrol acetate also has anti-androgenic properties. It is given by mouth in the palliative treatment or as an adjunct to other therapy in endometrial carcinoma and in breast cancer. Megestrol acetate has been approved to treat anorexia and cachexia.

Medroxyprogesterone is used in the treatment of renal carcinoma. It is a synthetic progestational hormone used in veterinary practice as an estrus regulator.

Chlormadinone acetate (Gestafortin) is an orally active synthetic progestational hormone used often in combinations as an oral contraceptive.

Estradiol dipropionate (17-Beta-Estradiol-3,17-Dipropionate) is a synthetic ester, specifically the 3, 17-dipropanoyl ester, of the natural estrogen, estradiol.

Lynestrenol is a synthetic progestational hormone, is the progesterone receptor agonist

Norethindrone acetate (19-Norethindroneacetate) is an oestrogen with inhibitory effects on adolescent menstruation and hepatic adenomas and is often used in combination with progestins in the study of endometriosis.

Etonogestrel (Implanon) is a steroidal progestin used as hormonal contraceptives.

Cridanimod (10-carboxymethyl-9-acridanone, CMA) is a potent STING agonist that directly binds to STING and triggers a strong antiviral response through the TBK1/IRF3 route.

Nestoron (Segesterone Acetate), a synthetic progestin, is a high-affinity agonist of the progesterone receptor (EC50: 10.3 nM).

U-46619 is an effective thromboxane A2 (TXA2) agonist and a thromboxane A2 analog (endoperoxide), capable of inducing contraction in the aortic smooth muscle (SM) of mice with a myosin light chain 9 (Myl9) gene deletion.

Dienogest (STS 557) is an orally-active, semisynthetic, fourth generation, nonethinylated progestogen with antiproliferative, antiandrogenic, anti-inflammatory and antiangiogenic activities that is used in hormone therapy and as a female contraceptive.

Ulipristal is a selective SPRM for emergency contraception after an unprotected intercourse or contraceptive failure.

Norgestimate is an acetylated progestinused in combination with ethinyl estradiol as an oral contraceptive.

Melengestrol acetate is a derivative of progesterone and acts as a corticosteroid hormone. Melengestrol acetate promotes endometrial proliferation delay of menstrual activity and pregnancy maintenance.

Nomegestrol acetate is a widely used progestin-like drug,which is characterized as a full agonist at the progesterone receptor

Altrenogest (Allyltrenbolone)(A35957; RU2267), a progestogen, has structural relation with veterinary steroid trenbolone.

Norethindrone (Norethisterone) is a synthetic progestational hormone with actions similar to those of PROGESTERONE but functioning as a more potent inhibitor of ovulation. It has weak estrogenic and androgenic properties. The hormone has been used in treating amenorrhea, functional uterine bleeding, endometriosis, and for contraception.

Drospirenone (ZK 3059) is a synthetic spironolactone analogue and progestin with progestational and anti-mineralocorticoid activity.

17α-Hydroxyprogesterone (17-OHP) is a physiological progestin that is produced during glucocorticoid and steroid hormone synthesis and is increased during the third trimester of pregnancy. Hydroxyprogesterone binds to the cytoplasmic progesterone receptors in the reproductive system and subsequently activates progesterone receptor-mediated gene expression.
