estrogen receptor/err

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.

Vepdegestrant (ARV-471) is a selective and highly potent estrogen receptor (ER, ESR1) PROTAC degrader with strong degrading activity against the ER protein. By directly degrading the ER protein rather than merely antagonizing its activity, vepdegestrant effectively inhibits the ER signaling pathway and demonstrates significant antitumor activity in ER-positive (ER⁺) breast cancer, with a DC50 value of approximately 2 nM. It is particularly effective against tumors harboring ESR1 mutations.

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.

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.

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.

Camizestrant (Estrogen receptor antagonist 2) is an antagonist of the estrogen receptor and can be used in studies about ER+ HER2-advanced breast cancer[1].

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

Pipendoxifene hydrochloride is a selective modulator of estrogen receptor.

(Rac)-Acolbifene (EM-343) is the racemic form of Acolbifene. Acolbifene is a estrogen receptor antagonist. (Rac)-Acolbifene exhibits anti-estrogenic and estrogenic activities. (Rac)-Acolbifene contains a piperidine ring and exhibits good pharmacological profile,relative binding affinity (RBA)=380.

G36 is a cell-permeable non-steroidal antagonist of GPER. G36 inhibits activation by either 17β-estradiol or the GPER-selective agonist G-1 (IC50 = 112 and 165 nM, respectively). G36 has no detectable binding activity to either ERα or ERβ. G36 blocks the activation of PI3K or calcium mobilization triggered by estrogen through GPER and it suppresses ERK activation by estrogen or G-1 but not by EGF. G-36 can be used in combination with GPER-selective agonists, like G-1, to distinguish the roles of GPER from those of ERα and ERβ in complex biological systems.

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.

Endoxifen hydrochloride, a principal active metabolite of Tamoxifen (TAM), exhibits heightened affinity and specificity towards the estrogen receptor and possesses aromatase inhibitory capability. It holds promise for breast cancer research.

LY88074 is a raloxifene analog in which the basic side chain has been removed. LY88074 is an agonist of ERβ (EC50 = 232 nM).This compound stimulates uterine cell proliferation.

Cancer-Targeting Compound 1 can be used in the study of hormone-related cancers, including the treatment or prevention of fibroids, uterine leiomyomas, polycystic ovarian syndrome, or hormone-dependent Cancer, among others.

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

Indazole-Cl is a selective ERß agonist and a selective estrogen receptor modifier (SERM).

Estredox (E2 CDS) is a redox-based estradiol (E2) chemical delivery system.E2-CDS provides sustained and brain-selective delivery of estradiol.

Fispemifene (HM-101) is an estrogen receptor modulator (SERM) used to treat genitourinary syndromes and vaginal atrophy.

GLL398 is an oral selective estrogen receptor down-regulating agent that strongly binds to ERα (IC50 =1.14 nM) and effectively degrades ERα in MCF-7 breast cancer cells (IC50 = 0.21 μM).
