디에틸스틸베스트롤 C화학적 특성, 용도, 생산
화학적 성질
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.
용도
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).
Indications
Diethylstilbestrol is one of the older synthetic estrogens in use. It was used to treat prostate cancer but is now rarely used for this purpose because of its adverse effects，although it is occasionally used in postmenopausal women with breast cancer. It is taken orally in tablet form.
정의
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Diethylstilbestrol is an olefinic compound that is trans-hex-3-ene in which the hydrogens at positions 3 and 4 have been replaced by p-hydroxyphenyl groups.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.
World Health Organization (WHO)
Diethylstilbestrol, a synthetic estrogen which is a stilbene
derivative, was introduced into obstetric practice in the late 1940s and
subsequently widely used for the treatment of threatened abortion. This use was
later shown to be associated with an increased risk of vaginal cancer in the
offspring which resulted in restrictive regulatory action in several countries.
Diethylstilbestrol and other stilbenes remain available in many countries, however,
for the treatment of certain hormone-dependent neoplasms including carcinoma of
the prostate and postmenopausal breast cancer.

These include sodium retention and oedema，nausea，gynaecomastia and impotence in men, and venous and arterial thrombosis. It can cause bone pain and hypercalcaemia when used for breast cancer.
Safety Profile
Confirmed carcinogen
producing skin, liver, and lung tumors in
exposed humans as well as uterine and other
reproductive system tumors in the female
offspring of exposed women. Experimental
carcinogenic, neoplas tigenic, tumorigenic,
and teratogenic data. A transplacental
carcinogen. A human teratogen by many
routes. Poison by intraperitoneal and
subcutaneous routes. It causes glandular
system effects by sktn contact. Human
reproductive effects by ingestion: abnormalspermatogenesis; changes in testes, epididymis, and sperm duct; menstrual cycle
changes or disorders; changes in female
ferulity; unspecified maternal effects;
developmental abnormalities of the fetal
urogenital system; germ cell effects in
offspring; and delayed effects in newborn.
Implicated in male impotence and
enlargement of male breasts. Other
experimental reproductive effects.
Mutation data reported. When heated to
decomposition it emits acrid smoke and
fumes. See also ETHINYL ESTRADIOL.
Carcinogenicity
Diethylstilbestrol is known to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in humans.
환경귀착
Diethylstilbestrol is a known teratogen and carcinogen.
Experimental studies using transgenic estrogen receptor
knockout animals suggest that binding and activation of the
estrogen receptor is required to elicit diethylstilbestrol
toxicity. Hence, diethylstilbestrol lesions primarily appear in
tissues enriched with estrogen receptors. Diethylstilbestrol
binds to the estrogen receptor with a very high affinity and
forms a complex with the target tissue. The complex then
internalizes in to the cell and translocates to the nucleus. Once
in the nucleus, diethylstilbestrol may directly bind with the
cellular DNA and cause mutations and unscheduled DNA
synthesis. Diethylstilbestrol is also known to induce
aneuploidy.
