Compound G-5b, an estrogen receptor modulator 10, functions as an estrogen receptor (ER) antagonist (IC50=6.7 nM) and degrader (DC50=0.4 nM). It has the capability to induce apoptosis and block cells at the G1 G0 phase, making it applicable in cancer research [1].

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.

Estradiol 3-sulfamate (BLE 00084) is an orally active and highly potent steroidal estrone sulfatase (ES) inhibitor.Estradiol 3-sulfamate has a K(i) value of 73 nM for ES in human placental microsomes and can be used in the study of breast cancer.

Camizestrant TFA (AZD-9833 TFA) is a potent and orally active antagonist of estrogen receptor (ER).

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

Vepdegestrant (ARV-471) is an estrogen receptor (ER) α PROTAC molecule that degrades ER in ER-positive breast cancer cell lines with a DC50 of approximately 1 nM. It can reduce the expression of classically regulated ER target genes and inhibit the growth of ER-dependent cell lines (including those expressing ESR1 variants, such as Y537S and D538G) by degrading ER.

Erteberel (LY500307) is a potent, selective estrogen receptor β agonist with EC50 of 0.66 nM, 32-fold selectivity against estrogen receptor α. Phase 2.

CHF-4227 is a novel, potent and selective estrogen receptor modulator that reduces cholesterol and LDL cholesterol concentrations.

Cyclopenta[c][1]benzopyran-8-ol, 1,2,3,3a,4,9b-hexahydro-4-(4-hydroxyphenyl)-, (3aR,4S,9bS)-rel- is an estrogen receptor beta (ERβ) agonist.

Octinoxate (Octyl 4-methoxycinnamate) is used is in sunscreens and other cosmetics to absorb UV-B rays from the sun, protecting the skin from damage,primarily as an ingredient in some sunscreens and lip balms. It is also used to reduce the appearance of scars.

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

Cholesterol is the primary sterol in mammals, accounting for approximately 20–25% of the plasma membrane structure. It plays a key role in regulating membrane fluidity, permeability, and protein function. As an endogenous agonist of estrogen-related receptor α (ERRα), cholesterol is widely involved in metabolic regulation and serves as a precursor for the synthesis of hormones and bile acids. It is commonly used in experimental models of hyperlipidemia.

Estrone (Aquacrine) is an aromatized C18 steroid with a 3-hydroxyl group and a 17-ketone, a major mammalian estrogen. It is converted from ANDROSTENEDIONE directly, or from TESTOSTERONE via ESTRADIOL. In humans, it is produced primarily by the cyclic ovaries, PLACENTA, and the ADIPOSE TISSUE of men and postmenopausal women.

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).

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.

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.

Palbociclib (PD 0332991) is a CDK inhibitor that inhibits CDK4 and CDK6 (IC50=11 16 nM) and is orally active. Palbociclib has anti-tumorigenic activity and has investigational potential for use in ER-positive and HER2-negative breast cancer.

Prochloraz (Prelude) is a broad-spectrum contact imidazole fungicide. Prochloraz inhibits human placental microsomal aromatase in vitro (IC50 = 40 nM). Prochloraz also acts as an estrogen receptor (IC50s = 25 μM) and androgen receptor (IC50 = 4 μM) antagonist, and activates aryl hydrocarbon receptors (EC50 = 1 μM).
