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.

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.

(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.

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

Panomifene HCl is a selective anti-estrogenic compound with antitumor activity for the treatment of breast cancer.

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.

Ethynyl estradiol is a semisynthetic alkylated ESTRADIOL with a 17-alpha-ethinyl substitution. It has high estrogenic potency when administered orally, and is often used as the estrogenic component in ORAL CONTRACEPTIVES.

Norethindrone (Norethisterone) is a synthetic progestational hormone with actions similar to those of PROGESTERONE but functioning as a more potent inhibitor of ovulation. It has weak estrogenic and androgenic properties. The hormone has been used in treating amenorrhea, functional uterine bleeding, endometriosis, and for contraception.

2-Hydroxyanthraquinone is an anthraquinone that has been found inSpermacoce latifoliaand has antibacterial and estrogenic activities.1,2It is active againstB. subtilisandB. cereus(MICs = 1.9 and 62.5 μg/ml, respectively).12-Hydroxyanthraquinone (19 μM) induces estrogen receptor α (ERα) activation in a yeast two-hybrid assay.2 1.Luo, Y., Shen, H.-Y., Shen, Q.-X., et al.A new anthraquinone and a new naphthoquinone from the whole plant of Spermacoce latifoliJ.

Thiacloprid is a neonicotinoid insecticide that acts as a selective agonist at insect nicotinic acetylcholine receptors (nAChRs) with IC50values of 2.7 and 860 nM forDrosophilanAChRs and M10 mouse fibroblast cells expressing α4β2 subunit-containing nAChRs, respectively.1It is active against aphids, whiteflies, various species of beetle, andLepidopteraspecies when used at concentrations ranging from 48 to 180 g AI/hectare.2It has anti-estrogenic activity in a yeast estrogen screen and is toxic to adult female houseflies and mice (LD50s = 0.03 and 28 mg/kg, respectively).1,3Formulations containing thiacloprid have been used in the control of insects in agriculture. 1.Tomizawa, M., and Casida, J.E.Selective toxicity of neonicotinoids attributable to specificity of insect and mammalian nicotinic receptorsAnnu.

4-tert-Octylphenol, an endocrine-disrupting chemical with estrogenic properties, notably induces apoptosis in offspring mouse brain neuronal progenitor cells. This compound decreases levels of bromodeoxyuridine (BrdU), mitotic marker Ki67, and phospho-histone H3 (p-Histone-H3), thereby diminishing the proliferation of neuronal progenitors. Consequently, 4-tert-Octylphenol adversely affects brain development and behavior in mice.
