Fosfestrol, sold under the brand name Honvan and also known as diethylstilbestrol diphosphate (DESDP), is an estrogen medication which is used in the treatment of prostate cancer in men. It is given by slow intravenous infusion once per day to once per week or by mouth once per day.
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.
Fenpentadiol (INN), also known as phenpentanediol, is a drug described as a tranquilizer and antidepressant that was formerly marketed in Europe. It also has stimulant, sedative, and anxiolytic effects, with the latter two occurring only at higher doses.
Paroxypropione, also known as paraoxypropiophenone, is a synthetic nonsteroidal estrogen which has been used medically as an antigonadotropin in Spain and Italy but appears to no longer be marketed. It was first synthesized in 1902. The antigonadotropic properties of the drug were discovered in 1951 and it entered clinical use shortly thereafter.
Doisynolic acid is a synthetic, orally active, nonsteroidal estrogen that was never marketed. The reaction of estradiol or estrone with potassium hydroxide, a strong base, results in doisynolic acid as a degradation product, which retains high estrogenic activity, and this reaction was how the drug was discovered, in the late 1930s. The drug is a highly active and potent estrogen by the oral or subcutaneous route. The reaction of equilenin or dihydroequilenin with potassium hydroxide was also found to produce bisdehydrodoisynolic acid, whose levorotatory isomer is an estrogen with an "astonishingly" high degree of potency, while the dextrorotatory isomer is inactive. Doisynolic acid was named after Edward Adelbert Doisy, a pioneer in the field of estrogen research and one of the discoverers of estrone.
Bifluranol is a synthetic nonsteroidal estrogen of the stilbestrol group related to diethylstilbestrol that has been used as an antiandrogen in the United Kingdom in the treatment of benign prostatic hyperplasia. The drug is described as a weak estrogen, and possesses about one-eighth the potency of diethylstilbestrol.
Dimestrol, also known as dianisylhexene, 4,4'-dimethoxy-α,α'-diethylstilbene, diethylstilbestrol dimethyl ether, and dimethoxydiethylstilbestrol, is a synthetic nonsteroidal estrogen of the stilbestrol group which is related to diethylstilbestrol. It has been used clinically as a hormonal therapy in cases of delayed female puberty, hypogonadism, menopausal, and postmenopausal symptoms. It is known to induce the development of female secondary sexual characteristics in the case of female delayed puberty or hypogonadism. The drug has also been used as a growth promoter in livestock.
Gestadienol, also known as 6-dehydro-17α-hydroxy-19-norprogesterone, is a steroidal progestin of the 19-norprogesterone group that was never marketed.
Cismadinone (INN), also known as 6α-chloro-17α-hydroxypregna-1,4-diene-3,20-dione or 6α-chloro-δ1-dehydro-17α-hydroxyprogesterone, is a steroidal progestin closely related to the 17α-hydroxyprogesterone derivatives that was never marketed. An acetylated form, cismadinone acetate, also exists, but similarly to cismadinone, was never marketed.
Clomegestone (INN), or clomagestone, also known as 6-chloro-17α-hydroxy-16α-methylpregna-4,6-diene-3,20-dione, is a steroidal progestin of the 17α-hydroxyprogesterone group that was never marketed. An acetate ester, clomegestone acetate, also exists, and similarly was never marketed.
Mestilbol, also known as diethylstilbestrol monomethyl ether, is a synthetic nonsteroidal estrogen of the stilbestrol group related to diethylstilbestrol. It was developed by Wallace & Tiernan Company, patented in 1940, and introduced for medical use in the 1940s, but is now no longer marketed. Mestilbol was available both as oral tablets and in oil for intramuscular injection. The drug is gradually demethylated in the body into diethylstilbestrol and hence is a prodrug of diethylstilbestrol. Mestilbol is a highly active estrogen, although somewhat less so than diethylstilbestrol, but is longer-lasting in comparison.
Terfluranol is a synthetic, nonsteroidal estrogen of the stilbestrol group related to diethylstilbestrol that was developed for the treatment of breast cancer but was never marketed. It was described in the medical literature in 1974.
Pentafluranol is a synthetic, nonsteroidal estrogen of the stilbestrol group related to diethylstilbestrol that was developed for the treatment of benign prostatic hyperplasia never marketed. It was described in the medical literature in 1974.
Diethylstilbestrol diacetate (DESDA) is a synthetic, nonsteroidal estrogen of the stilbestrol group and an ester of diethylstilbestrol (DES) that was introduced for clinical use in the 1940s and was formerly marketed but is now no longer available.
Diethylstilbestrol dilaurate is a synthetic, nonsteroidal estrogen of the stilbestrol group and an ester of diethylstilbestrol (DES) that was previously marketed but is now no longer available. It was formulated and used as a micronized topical medication to treat acne in adolescent boys and young men. The drug was marketed as early as 1951.
Diethylstilbestrol monobenzyl ether, also known as benzelstilbestrol, is a synthetic, nonsteroidal estrogen of the stilbestrol group and an ether of diethylstilbestrol (DES) that is described as a pituitary gland inhibitor (antigonadotropin) and was formerly marketed but is now no longer available. It was first synthesized by Wallace & Tiernan Company in 1952, and was described by them as having only weak estrogenic activity. The drug was used to treat gynecological conditions and infertility in women.
Diethylstilbestrol disulfate is a synthetic, nonsteroidal estrogen of the stilbestrol group and an ester of diethylstilbestrol (DES) that was formerly marketed but is now no longer available. It is described as an antineoplastic agent.
ICI-85966, also known as diethylstilbestrol (DES) bis(di carbamate), is a synthetic, nonsteroidal estrogen and cytostatic antineoplastic agent of the stilbestrol group and a nitrogen mustard ester of diethylstilbestrol (DES) which was developed for the treatment of breast cancer and prostate cancer but was never marketed.
Triphenylchloroethylene, 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.
