Meprednisone is a glucocorticoid. It is a methylated derivative of prednisone.
Zuclomifene (INN; or zuclomiphene (USAN)) is a nonsteroidal selective estrogen receptor modulator (SERM) of the triphenylethylene group that was never marketed. It is one of the two stereoisomers of clomifene, which itself is a mixture of 38% zuclomifene and 62% enclomifene. Zuclomifene is the (Z)-stereoisomer of clomifene, while enclomifene is the (E)-stereoisomer. Whereas zuclomifene is described as mildly estrogenic, enclomifene is described as antiestrogenic. In accordance, unlike enclomifene, zuclomifene is antigonadotropic due to activation of the estrogen receptor and reduces testosterone levels in men. It is also about five times more potent than enclomifene in inducing ovulation.
Canrenoic acid is a synthetic steroidal antimineralocorticoid which was never marketed.
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.
Tiomesterone is a synthetic, orally active anabolic-androgenic steroid (AAS) and a 17α-alkylated derivative of testosterone. It was described in 1963.
Gestaclone, also known as 6-chloro-1α,2α:16α,17-bismethylene-4,6-pregnadiene-3,20-dione, is a steroidal progestin of unique chemical structure derived from progesterone that was first described in 1967 and was never marketed.
Chloroprednisone acetate is a synthetic glucocorticoid corticosteroid and a corticosteroid ester. It is the 21-acetate ester of chloroprednisone.
Butidrine (INN), or butedrine or butydrine, also known as hydrobutamine or idrobutamine, is a beta blocker related to pronethalol and propranolol that was developed in the 1960s. Similarly to certain other beta blockers, butidrine also possesses local anesthetic properties.
Haloprogesterone, sold under the brand name Prohalone, is a progestin medication which was previously marketed by Ayerst but is now no longer available.
Furostilbestrol (INN), also known as diethylstilbestrol di(2-furoate) or simply as diethylstilbestrol difuroate, is a synthetic, nonsteroidal estrogen of the stilbestrol group related to diethylstilbestrol, that was never marketed. It is an ester of diethylstilbestrol and was described in the literature in 1952.
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.
Stenbolone acetate (USAN), also known as 2-methyl-4,5α-dihydro-δ1-testosterone 17β-acetate or as 2-methyl-5α-androst-1-en-17β-ol-3-one 17β-acetate, is a synthetic, injected anabolic–androgenic steroid (AAS) and derivative of dihydrotestosterone (DHT) which has been marketed in Spain.
Nisterime (INN), also known as 2α-chloro-4,5α-dihydrotestosterone 3-O-(p-nitrophenyl)oxime or as 2α-chloro-5α-androstan-17β-ol-3-one 3-O-(p-nitrophenyl)oxime, is a synthetic anabolic-androgenic steroid (AAS) and a derivative of dihydrotestosterone (DHT) that was never marketed. The C17α acetate ester of nisterime, nisterime acetate (ORF-9326), also exists and was developed as a postcoital contraceptive but was similarly never marketed.
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.
Dicirenone is a synthetic, steroidal antimineralocorticoid of the spirolactone group which was developed as a diuretic and antihypertensive agent but was never marketed. It was synthesized and assayed in 1974. Similarly to other spirolactones like spironolactone, dicirenone also possesses antiandrogen activity, albeit with relatively reduced affinity.
Deprodone, also known as desolone, is a synthetic glucocorticoid corticosteroid.
Cloticasone is a synthetic glucocorticoid corticosteroid which was never marketed.
Timobesone is a synthetic glucocorticoid corticosteroid which was never marketed.
Oxisopred is a synthetic glucocorticoid corticosteroid which was never marketed.
