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

Tamoxifen Citrate is an orally active selective estrogen receptor modulator (SERM) that blocks estrogen activity in breast cells while activating estrogen signaling in cells such as those of the bone, liver, and uterus. As an Hsp90 activator, it enhances the ATPase activity of the Hsp90 chaperone complex, induces autophagy and apoptosis, and can be used to generate gene knockout models in CreER(T2) transgenic mice as well as liver injury models.

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).

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

Bazedoxifene hydrochloride (TSE 424 hydrochloride) is an orally active, selective, and potent estrogen receptor modulator (SERM) that crosses the blood-brain barrier and is an inhibitor of IL-6/GP130 protein interactions with high affinity for ERα and ERβ. It has a high affinity for ERα and ERβ and can be used to study postmenopausal osteoporosis and vasodilator-related diseases.

Fadrozole hydrochloride (CGS 16949A) is a model aromatase inhibitor that effectively suppresses estrogen production in fish ovaries.

DPN (Diarylpropionitrile) is an selective agonist of estrogen receptor β (ERβ) .

FLTX1 is a fluorescent derivative of Tamoxifen, designed to efficiently target and label intracellular Tamoxifen-binding sites (estrogen receptors) both under permeabilized and non-permeabilized conditions. Additionally, FLTX1 demonstrates strong antiestrogenic activity in breast cancer cells, resembling the potent antiestrogenic properties of Tamoxifen. Notably, FLTX1 does not exhibit any estrogenic agonistic effect on the uterus.

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.

Astragaloside IV (AS-IV), an active component isolated from Astragalus membranaceus, suppresses the activation of ERK1/2 and JNK, and downregulates matrix metalloproteases (MMP)-2, (MMP)-9 in MDA-MB-231 breast cancer cells. Astragaloside IV is a bioactive saponin first isolated from the dried plant roots of the genus Astragalus, which is used in traditional Chinese medicine.1 It dose-dependently inhibits human adenovirus type 3 (HAdV-3) in A549 cells (IC50 = 23 μM; LC50 = 865 μM).It inhibits replication of HAdV-3 and decreases HAdV-3-induced apoptosis. It has diverse protective effects for the cardiovascular, immune, digestive, and nervous systems. In particular, it reduces myocardial infarct size in dogs when administered prior to coronary ligation and reduces reperfusion arrhythmias in isolated rat hearts.

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 is an orally active selective estrogen receptor modulator (SERM) that acts as an estrogen antagonist in breast cells and an agonist in bone, liver, and uterine cells. It can be used to induce gene knockout and liver injury models in mice, and also exhibits multiple biological activities, including activation of Hsp90, induction of autophagy and apoptosis, and inhibition of EBOV and MARV viral infections.

10β,17β-dihydroxyestra-1,4-dien-3-one (DHED) is a brain-selective prodrug of 17β-estradiol, which has neuroprotective effects, improves cognitive dysfunction, and can be used to study brain damage.

Acolbifene (SCH 57068) is a selective antagonist of estrogen receptors with IC50s of 2 nM and 0.4 nM for estradiol-induced transcriptional activity of ERα and ERβ. Acolbifene shows an anticarcinogenic property.

Droloxifene (3-Hydroxytamoxifen), a tamoxifen derivative, is an oral active and selective estrogen receptor modulator.Droloxifene induced p53 expression and apoptosis in McF-7 cells.Fluroxifene has anti-estrogen and anti-implantation effects.Fluroxifene prevented bone loss in ovariectomized rats.

Giredestrant tartrate (Estrogen receptor antagonist 1) is a novel, orally active, selective and effective non-steroidal estrogen receptor antagonist. Giredestrant tartrate strongly binds to ER, resulting in the failure of ER to activate the transcription of targeted genes and promoting the degradation of ER protein. Giredestrant tartrate can be used to treat tumor diseases.
