Liquiritigenin (4',7-Dihydroxyflavanone), a flavonoid aglycone from licorice, is a highly selective estrogen receptor β (ERβ) agonist.

Alpha-Estradiol (Epiestradiol) is an estrogen that inhibits 5alpha-reductase and has potential in the study of androgenetic alopecia.

NXT629 is a selective and highly efficient PPAR-α antagonist with anticancer activity. It inhibits PPARδ, PPARγ, Erβ, GR, and TRβ and can be used in research on ovarian cancer and melanoma.

Elacestrant (RAD1901) with IC50s of 48 and 870 nM for ERα and ERβ, respectively.Elacestrant  is an orally available selective estrogen receptor degrader .

ERα ERβ antagonist-1 (Compound 10) functions as a partial antagonist of both ERα and ERβ. It reduces the activity of ERα and ERβ in HepG2 liver cells in a dose-dependent manner.

(±)-Equol ((R,S)-Equol) is a non-steroidal estrogen produced from the metabolism of the isoflavonoid phytoestrogen daidzen by human intestinal microflora. The estrogen receptor (ER) agonist activity of the naturally occurring (S)-enantiomer (EC50 = 85 and 65 nM for human ERα and ERβ, respectively) is similar to that of genistein but exceeds that of daidzein. (±)-Equol preferentially binds ERβ (Ki = 0.73 nM) and demonstrates approximately 9-fold lower affinity for ERα (Ki = 6.41 nM). (±)-Equol is also a potent antagonist of dihydrotestosterone, which has important implications for prostate cancer and other androgen-mediated pathologies.

PHTPP is a selective ERβ antagonist.

Fulvestrant (ZM 182780) is an estrogen receptor (ER) antagonist (IC50=9.4 nM) and an agonist of GPR30. Fulvestrant has antitumor activity, inhibiting cell proliferation and inducing apoptosis and autophagy.

4-Hydroxytamoxifen (ICI 79280) is the active metabolite of Tamoxifen, an estrogen receptor modulator (SERM) with selective and oral potency. 4-Hydroxytamoxifen has antitumor activity and may be used in breast cancer research.

Tamoxifen (ICI47699) is a selective and orally effective estrogen receptor modulator (SERM). Tamoxifen has both inhibitory (e.g., mammary cells) and activating (e.g., bone, liver, and uterine cells) activity against estrogens.

Zindoxifene (D 16726) is an anti-estrogenic compound with antitumor activity that can be used in studies of breast and prostate cancer.

Estrogen receptor antagonist 8 acts as an estrogen receptor (ER) antagonist with anti-uterine activity and potential anti-tumorigenic activity and can be used to study ovarian dysfunction.

Estradiol (E2) is a naturally occurring steroidal sex hormone that is essential for female fertility and maintenance of secondary sexual characteristics. Estradiol upregulates IL-6 expression through estrogen receptor beta (ERβ).

Ethisterone (17α-Ethynyltestosterone) is a progestogen hormone.

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.

Tamoxifen is an antineoplastic nonsteroidal selective estrogen receptor modulator (SERM).

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.

Raloxifene hydrochloride (LY156758 hydrochloride) is a second generation selective estrogen receptor modulator (SERM) used to prevent osteoporosis in postmenopausal women. It has estrogen agonist effects on bone and cholesterol metabolism but behaves as a complete estrogen antagonist on mammary gland and uterine tissue.

Kaempferol (Robigenin) is a natural flavonoid and an inverse agonist of ERRα and ERRγ. Kaempferol has a wide range of antitumor, anti-inflammatory, antioxidant, antibacterial and antiviral activities.

Ferrous Bisglycinate (Bisglycine iron(II) salt) is used in the fortification of infant formulations and foods.

Ethynyl estradiol is a semisynthetic alkylated ESTRADIOL with a 17-alpha-ethinyl substitution. It has high estrogenic potency when administered orally, and is often used as the estrogenic component in ORAL CONTRACEPTIVES.

OBHSA(Oxabicycloheptane sulfonamide) is a novel selective estrogen receptor depressant (SERD) that can be used to study breast cancer.
