Chlorotrianisene (tri-p-anisylchloroethylene) 是长效、可口服、亲脂性高的合成三苯乙烯 (TPE) 衍生物和选择性雌激素受体调节剂，有雌激素活性，也有抗雌激素活性。它还有效抑制COX-1并抑制全血中的血小板聚集。

Tracheloside 是抗雌激素木质素，利用 ERK1 2 刺激促进角质形成细胞增殖，是一种良好的促进伤口愈合的药物。

FLTX1是Tamoxifen的一种荧光衍生物，旨在有效地靶向并标记细胞内的Tamoxifen结合位点（雌激素受体），无论是在渗透性或非渗透性条件下。此外，FLTX1在乳腺癌细胞中展示出强烈的抗雌激素活性，类似于Tamoxifen的强大抗雌激素属性。值得注意的是，FLTX1在子宫上不表现出任何雌激素激动剂效应。

7-Hydroxyflavanone 对肺炎链球菌临床分离株显示出抗菌活性。

22393-62-0_peak 2 exhibits some aspects of the antiestrogenic activity and other actions that may be connected to the estrogenic properties. A mixture of the (Z)- and (E)-isomers (Broparestrol, INN) is used in dermatology.

Endoxifen E-isomer (E-Endoxifen) 是一种 Endoxifen 的 E-异构体，是 Endoxifen Z-isomer 原料中主要的杂质。Endoxifen E-isomer 具有抗雌激素活性。

N-Desmethyltamoxifen, the principal metabolite of tamoxifen in humans, serves as an efficacious modulator of ceramide metabolism within human AML cells by inhibiting ceramide glycosylation, hydrolysis, and sphingosine phosphorylation. Although it demonstrates weak antiestrogenic properties, it acts as a protein kinase C (PKC) inhibitor with a potency ten times greater than that of tamoxifen.

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

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.

RU 45144 is an estradiol derivative with antiestrogenic activity.

LY 183648 has antiestrogenic activity. LY117018 inhibited PAIII metastasis to the gluteal (97%) and iliac lymph nodes (88%).

Arzoxifene (LY353381) is an orally active selective estrogen receptor modulator (SERM) exhibiting a fixed ring structure analogous to raloxifene. This compound demonstrates potent antiestrogenic effects on breast cancer and endometrium while displaying minimal side effects. Additionally, Arzoxifene elicits favorable estrogenic effects on bone health and lipid profile.

HIF-1α-IN-3, also known as Compound (S)-3f, is a hypoxia-selective inhibitor of HIF-1α. It exhibits potent antiestrogenic activity [1].

TAS-108, also known as SR16234, is a synthetic, antiestrogenic steroidal compound with potential antitumor activity. TAS-108 binds to and inhibits estrogenic receptor alpha (ERa), mainly expressed in the mammary gland and uterus and upregulated in estrogen-dependent tumors. Blockage of ERa by TAS-108 prevents the binding and effects of estrogen and may lead to an inhibition of estrogen-dependent cancer cell proliferation. TAS-108 also is a partial agonist of the estrogenic receptor beta (ERb), expressed in many tissues including the central nervous system, urogenital tract, bone and cardiovascular system, thereby exerting a positive effect on these tissues.

Millewanin G shows antiestrogenic activity.

Millewanins H shows antiestrogenic activity.

Pachyaximine A possesses significant antibacterial activity against Escherichia coli, Staphylococcus aureus, Corynebacterium diphtheriae and Corynebacterium pyrogenes. (-)-Pachyaximine A demonstrates significant activity as antiestrogen binding site (AEBS
