Acefluranol (developmental code name BX-591), also known as 2,3-bis(3,4-diacetoxy-5-fluorophenyl)pentane, is a nonsteroidal antiestrogen of the stilbestrol group that was never marketed. [1] [2]
Fluorometholone, also known as 6α-methyl-9α-fluoro-11β,17α-dihydroxypregna-1,4-diene-3,20-dione, is a synthetic glucocorticoid which is used in the treatment of inflammatory eye diseases. The C17α acetate ester, fluorometholone acetate, is also a glucocorticoid and is used for similar indications.
Oxabolone cipionate, or oxabolone cypionate, also known as 4-hydroxy-19-nortestosterone 17β-cypionate or estr-4-en-4,17β-diol-3-one 17β-cypionate, is synthetic and injected anabolic–androgenic steroid (AAS) and derivative of nandrolone (19-nortestosterone) which has been marketed in Europe. It is the C17β cypionate ester and a prodrug of oxabolone (4-hydroxy-19-nortestosterone).
Bolazine (INN), also known as 2α-methyl-5α-androstan-17β-ol-3-one azine, is a synthetic androgen/anabolic steroid (AAS) of the dihydrotestosterone (DHT) group which was never marketed. It is not orally active and is used as the ester prodrug bolazine capronate via depot intramuscular injection. Bolazine has a unique and unusual chemical structure, being a dimer of drostanolone linked at the C3 position of the A-ring by an azine group, and reportedly acts as a prodrug of drostanolone.
Oxymesterone, also known as methandrostenediolone, as well as 4-hydroxy-17α-methyltestosterone or 17α-methylandrost-4-en-4,17β-diol-3-one, is an orally active anabolic-androgenic steroid (AAS). It was known by 1960.
Metogest, also known as 16,16-dimethyl-19-nortestosterone, is a steroidal antiandrogen that was patented in 1975 and investigated as a treatment for acne but was never marketed.
Penmesterol (INN), or penmestrol, also known as 17α-methyltestosterone 3-cyclopentyl enol ether, is a synthetic, orally active anabolic-androgenic steroid (AAS) that was developed in the early 1960s. It is the 3-cyclopentyl enol ether of methyltestosterone.
Quinestradol, also known as quinestradiol or quinestriol, as well as estriol 3-cyclopentyl ether (E3CPE), is a synthetic estrogen and estrogen ether which is no longer marketed. It is the 3-cyclopentyl ether of estriol. The medication has been studied in the treatment of stress incontinence in elderly women, with effectiveness observed.
Flugestone, also known as flurogestone, as well as 9α-fluoro-11β,17α-dihydroxyprogesterone, is a steroidal progestin of the 17α-hydroxyprogesterone group that was never marketed. An acetate ester, flurogestone acetate, is used in veterinary medicine.
Pentagestrone (INN), also known as 17α-hydroxyprogesterone 3-cyclopentyl enol ether, is a steroidal progestin of the 17α-hydroxyprogesterone group that was never marketed. An acetate ester, pentagestrone acetate, has been marketed for clinical use. Pentagestrone was described in the literature in 1960.
Clogestone, also known as chlormadinol or as 3β,17α-dihydroxy-6-chloropregna-4,6-diene-20-one, is a steroidal progestin that was synthesized in 1964 and was investigated as a progestin-only contraceptive but was never marketed. A diacetate ester, clogestone acetate, also exists and similarly was never marketed.
Amadinone acetate (USAN), also known as 19-norchlormadinone acetate, is a steroidal progestin of the 19-norprogesterone and 17α-hydroxyprogesterone groups that was never marketed. It is the acetate ester of amadinone, which, similarly, was never marketed.
Bolazine capronate (INN), also known as bolazine caproate or bolazine hexanoate, as well as di(drostanolone capronate) azine or 2α-methyl-5α-androstan-17β-ol-3-one 17β-hexanoate azine, is a synthetic, injected androgen/anabolic steroid (AAS), and derivative of dihydrotestosterone (DHT). It is an androgen ester – specifically, the C17β hexanoate ester of bolazine.
Clostebol acetate (BAN), also known as 4-chlorotestosterone 17β-acetate (4-CLTA) or as 4-chloroandrost-4-en-17β-ol-3-one 17β-acetate, is a synthetic, injected anabolic-androgenic steroid (AAS) and a derivative of testosterone that is marketed in Germany and Italy. It is an androgen ester – specifically, the C17β acetate ester of clostebol (4-chlorotestosterone) – and acts as a prodrug of clostebol in the body. Clostebol acetate is administered via intramuscular injection.
Clomifenoxide (INN), also known as clomifene N-oxide, is a nonsteroidal selective estrogen receptor modulator (SERM) of the triphenylethylene group that is described as an antiestrogen and "gonad stimulant" and was never marketed. It is an active metabolite of clomifene.
Androstenediol dipropionate, or 5-androstenediol 3β,17β-dipropionate, also known as androst-5-ene-3β,17β-diol 3β,17β-dipropionate, is a synthetic anabolic–androgenic steroid and an androgen ester – specifically, the dipropionate diester of 5-androstenediol (androst-5-ene-3β,17β-diol) – which has been marketed in Europe, including in Spain, Italy, and Austria.
Estramustine is an estrogen and cytostatic antineoplastic agent which was never marketed. It is an estrogen ester – specifically, the C3 normustine ester of estradiol – and acts in part as a prodrug of estradiol in the body. Estramustine phosphate, the C17β phosphate ester of estramustine and a prodrug of estramustine, estromustine, estradiol, and estrone, is marketed and used in the treatment of prostate cancer.
Dacuronium bromide is an aminosteroid neuromuscular blocking agent which was never marketed. It acts as a competitive antagonist of the nicotinic acetylcholine receptor (nAChR).
Timobesone is a synthetic glucocorticoid corticosteroid which was never marketed.
Cortobenzolone, also known as betamethasone salicylate, is a synthetic glucocorticoid corticosteroid and corticosteroid ester which is marketed in Spain.
Estrone methyl ether, or estrone 3-methyl ether, is a synthetic estrogen and estrogen ether – specifically, the C3 methyl ether of estrone – which was never marketed. It has been used to synthesize mestranol.
