Triphenylchloroethylene
Triphenylchloroethylene (TPCE; brand names Gynosone, Oestrogyl), or triphenylchlorethylene, also known as chlorotriphenylethylene or as phenylstilbene chloride, is a synthetic nonsteroidal estrogen of the triphenylethylene group that was marketed in the 1940s for the treatment of menopausal symptoms, vaginal atrophy, lactation suppression, and all other estrogen-indicated conditions. The estrogenic effects of triphenylethylene, the parent compound of triphenylchloroethylene, were discovered in 1937. Triphenylchloroethylene was first reported in 1938 and was found to have 20 to 100 times the estrogenic activity of the relatively weak triphenylethylene, a potentiation of effect that was afforded by its halogen substituent. The drug has a relatively long duration of action when administered via subcutaneous injection but a duration similar to that of diethylstilbestrol or estradiol benzoate when administered orally. Along with diethylstilbestrol and triphenylmethylethylene, triph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triphenylbromoethylene
Triphenylbromoethylene (TPBE; brand names Bromylene, Eitriphin, Oestronyl, Prostilban, Tribenorm), also known as bromotriphenylethylene or as phenylstilbene bromide, is a synthetic nonsteroidal estrogen of the triphenylethylene group that was marketed in the 1940s similarly to the closely related estrogen triphenylchloroethylene. A di ethoxylated derivative of triphenylbromoethylene, estrobin (DBE), is also an estrogen, but, in contrast, was never marketed. An ethylated derivative of triphenylbromoethylene, broparestrol (BDPE), is a selective estrogen receptor modulator (SERM) that has been marketed.

Nonsteroidal Estrogen
A nonsteroidal estrogen is an estrogen with a nonsteroidal chemical structure. The most well-known example is the stilbestrol estrogen diethylstilbestrol (DES). Although nonsteroidal estrogens formerly had an important place in medicine, they have gradually fallen out of favor following the discovery of toxicities associated with high-dose DES starting in the early 1970s, and are now almost never used. On the other hand, virtually all selective estrogen receptor modulators (SERMs) are nonsteroidal, with triphenylethylenes like tamoxifen and clomifene having been derived from DES, and these drugs remain widely used in medicine for the treatment of breast cancer among other indications. In addition to pharmaceutical drugs, many xenoestrogens, including phytoestrogens, mycoestrogens, and synthetic endocrine disruptors like bisphenol A, are nonsteroidal substances with estrogenic activity. Pharmacology Nonsteroidal estrogens act as agonists of the estrogen receptors, ERα and ERβ. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synthetic Compound
In chemistry, organic compounds are generally any chemical compounds that contain carbon-hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. The study of the properties, reactions, and syntheses of organic compounds comprise the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonate salts and cyanide salts), along with a few other exceptions (e.g., carbon dioxide, hydrogen cyanide), are not classified as organic compounds and are considered inorganic. Other than those just named, little consensus exists among chemists on precisely which carbon-containing compounds are excluded, making any rigorous definition of an organic compound elusive. Although organic compounds make up only a small percentage of Earth's crust, they are of central importance because all known life is based on organic compounds. Living t ...

Triphenylethylene
Triphenylethylene (TPE) is a simple aromatic hydrocarbon that possesses weak estrogenic activity. Its estrogenic effects were discovered in 1937. TPE was derived from structural modification of the more potent estrogen diethylstilbestrol, which is a member of the stilbestrol group of nonsteroidal estrogens. TPE is the parent compound of a group of nonsteroidal estrogen receptor ligands. It includes the estrogens chlorotrianisene, desmethylchlorotrianisene, estrobin (DBE), M2613, triphenylbromoethylene, triphenylchloroethylene, triphenyliodoethylene, triphenylmethylethylene; the selective estrogen receptor modulators (SERMs) afimoxifene, brilanestrant, broparestrol, clomifene, clomifenoxide, droloxifene, endoxifen, etacstil, fispemifene, idoxifene, miproxifene, miproxifene phosphate, nafoxidine, ospemifene, panomifene, and toremifene. The antiestrogen ethamoxytriphetol (MER-25) is also closely related, but is technically not a derivative of TPE and is instead a triphenyleth ...

Broparestrol
Broparestrol () (brand names Acnestrol, Longestrol; former developmental code name LN-107), also known as α-bromo-α,β-diphenyl-β-p-ethylphenylethylene (BDPE), is a synthetic, nonsteroidal selective estrogen receptor modulator (SERM) of the triphenylethylene group that has been used in Europe as a dermatological agent and for the treatment of breast cancer. The drug is described as slightly estrogenic and potently antiestrogenic, and inhibits mammary gland development and suppresses prolactin levels in animals. It is structurally related to clomifene and diethylstilbestrol. Broparestrol is a mixture of ''E-'' and ''Z-'' isomers (LN-1643 and LN-2299, respectively), both of which are active and are similarly antiestrogenic but, unlike broparestrol, were never marketed.

Chlorotrianisene
Chlorotrianisene (CTA), also known as tri-''p''-anisylchloroethylene (TACE) and sold under the brand name Tace among others, is a nonsteroidal estrogen related to diethylstilbestrol (DES) which was previously used in the treatment of menopausal symptoms and estrogen deficiency in women and prostate cancer in men, among other indications, but has since been discontinued and is now no longer available. It is taken by mouth. CTA is an estrogen, or an agonist of the estrogen receptors, the biological target of estrogens like estradiol. It is a high-efficacy partial estrogen and shows some properties of a selective estrogen receptor modulator, with predominantly estrogenic activity but also some antiestrogenic activity. CTA itself is inactive and is a prodrug in the body. CTA was introduced for medical use in 1952. It has been marketed in the United States and Europe. However, it has since been discontinued and is no longer available in any country. Medical uses CTA has been used i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estrobin
Estrobin, also known as α,α-di(''p''-ethoxyphenyl)-β-phenylbromoethylene and commonly abbreviated as DBE, is a Organic compound#Synthetic compounds, synthetic, nonsteroidal estrogen of the triphenylethylene group that was never marketed. Chlorotrianisene, and subsequently clomifene and tamoxifen, were derived from it. Estrobin, similarly to other triphenylethylenes, is very lipophilic and hence very long-lasting in its duration of action. Similarly to chlorotrianisene, estrobin behaves a prodrug to a much more potent estrogen in the body.

Organoiodides
Organoiodine compounds are organic compounds that contain one or more carbon–iodine bonds. They occur widely in organic chemistry, but are relatively rare in nature. The thyroxine hormones are organoiodine compounds that are required for health and the reason for government-mandated iodization of salt. Structure, bonding, general properties Almost all organoiodine compounds feature iodide connected to one carbon center. These are usually classified as derivatives of I−. Some organoiodine compounds feature iodine in higher oxidation states. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I. This periodic order also follows the atomic radius of halogens and the length of the carbon-halogen bond. For example, in the molecules represented by CH3X, where X is a halide, the carbon-X bonds have strengths, or bond dissociation energies, of 115, ...
