OP-1074 is a pure antiestrogen and a selective degrader of ER, shows specific antiestrogenic activity for ERα and ERβ.

Acolbifene hydrochloride binds to estrogen receptors in the body. It is a type of selective estrogen receptor modulator

Levormeloxifene is a selective modulator of the estrogen receptor. It inhibits the production of vaginal tropoelastin and transforming growth factor-beta 1.

Estrogen receptor β antagonist 2 是一种选择性的、有效的雌激素受体βestrogen receptor β (ERβ) 拮抗剂，作用于 Erα (IC50: 109.10 μM)和 Erβ (IC50: 0.63 μM)。

(1S,3R)-GNE-502 (compound 179) 是一种 Erα 的有效降解剂，能够在 MCF7 HCS 细胞中降解 ERα (EC50: 13 nM)。(1S,3R)-GNE-502 可以用于与雌激素受体相关癌症的研究。

MK-6913 is a potent and selective agonist of estrogen receptor β.

Zuclomiphene citrate is a cis isomer of Clomiphene citrate, and has an antiestrogenic effect and can inhibit the secretion of luteinizing hormone (LH) more than the trans isomer.

NNC45-0781 is a tissue-selective partial-agonist of estrogen.

GNE-274, a non-degrader compound structurally similar to GDC-0927 (an ER degrader), serves as a partial ER agonist in breast cancer cell lines without triggering ER turnover. Notably, GNE-274 enhances chromatin accessibility at ER-DNA binding sites, unlike GDC-0927. Acting as a potent inhibitor of the ER-ligand binding domain (LBD), GNE-274 exhibits potential for cancer research purposes.
