Estrogens diffuse into their target cells and interact with a protein receptor, the estrogen receptor. Target cells include the female reproductive tract, the mammary gland, the hypothalamus, and the pituitary. The effect of Estrogen binding their receptors causes downstream increases the hepatic synthesis of sex hormone binding globulin (SHBG), thyroid-binding globulin (TBG), and other serum proteins and suppress follicle-stimulating hormone (FSH) from the anterior pituitary. The combination of an estrogen with a progestin suppresses the hypothalamic-pituitary system, decreasing the secretion of gonadotropin-releasing hormone (GnRH).

使用Diethylstilbestrol is a synthetic nonsteroidal estrogen that was formerly used in estrogenic hormone therapy (for menstrual disorders, postpartum breast engorgement, postcoital contraceptive, prevention of spontaneous abortion) and in chemotherapy of various cancers, including postmenopausal breast cancer and prostate cancer. It was also used in biomedical research and veterinary medicine (growth promoter for cattle and sheep; veterinary drug to treat estrogen deficiency disorders).

56-53-1、6898-97-1DTXSID3040770化学的特性Diethylstilbestrol is an odorless, white crystalline powder, with a molecular weight of 268.36. Its cisisomer tends to revert to the trans-form. It is a nonsteroidal, synthetic stilbene derivative with estrogenic activity. recomended solvents are DMSO, DMF and ethanol, even in these solvents do not store in solution for any prolonged period of time.
定義ChEBI: Diethylstilbestrol is an olefinic compound that is trans-hex-3-ene in which the hydrogens at positions 3 and 4 have been replaced by p-hydroxyphenyl groups. It has a role as an antineoplastic agent, a carcinogenic agent, a xenoestrogen, an EC 3.6.3.10 (H(+)/K(+)-exchanging ATPase) inhibitor, an antifungal agent, an endocrine disruptor, an EC 1.1.1.146 (11beta-hydroxysteroid dehydrogenase) inhibitor, an autophagy inducer and a calcium channel blocker. It is a polyphenol and an olefinic compound.
