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 is a steroid hormone that regulates the menstrual cycle and is essential for pregnancy. It is also commonly used to induce melasma models.

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

Ethynodiol diacetate (Ethynodiol acetate) is a synthetic progestational hormone utilized alone or combined with estrogens as an oral contraceptive.

Mifepristone (C-1073) is a progesterone-receptor (IC50=0.2 nM) and glucocorticoid-receptor antagonist (IC50=2.6 nM). Mifepristone is used to terminate pregnancy, treat uterine fibroids, and treat endometriosis.

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.

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

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.

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.

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.

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.

Ulipristal acetate (CDB-2914) is an orally bioavailable selective progesterone receptor modulator with anti-progesterone activity. It binds to the progesterone receptor (PR), inhibiting PR-mediated gene expression and interfering with progesterone activity in the reproductive system, potentially suppressing the growth of uterine leiomyomatosis. Additionally, ulipristal can be used as emergency contraception by inhibiting or delaying ovulation and affecting endometrial tissue.

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

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.

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

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.

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

Gestonorone Capronate  is a progesterone used to treat benign prostatic hyperplasia and endometrial cancer.

Gestodene (WL 70) is a progestogen hormonal contraceptive.

CJ-42794 (CJ-042794) is a selective antagonist of the prostaglandin E receptor subtype 4 (EP4), inhibiting [3H]-PGE2 binding to the human EP4 receptor with a mean pKi of 8.5. It exhibits a binding affinity that is at least 200-fold more selective for the human EP4 receptor than for other human EP receptor subtypes (EP1, EP2, and EP3) (IC50: 8.5 (pKi)).

Norethisterone enanthate (NSC-9564) is a long-acting parenteral progestogen with antigonadotropic effects.

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