17α-Ethynyl-3α-androstanediol (developmental code names HE-3235, Apoptone), also known as 17α-ethynyl-5α-androstane-3α,17β-diol, is a synthetic androstane steroid and a 17α-substituted derivative of 3α-androstanediol which was never marketed. It was under development for the treatment of prostate cancer but was discontinued.
17α-Ethynyl-3α-androstanediol itself shows very low affinity for steroid receptors, including the ARTooltip androgen receptor, ERαTooltip estrogen receptor alpha, ERβTooltip estrogen receptor beta, PRTooltip progesterone receptor, and GRTooltip glucocorticoid receptor, and its mechanism of action is not well-characterized. It produces 5α-dihydroethisterone (5α-dihydro-17α-ethynyltestosterone), a ligand of several steroid hormone receptors, and 17α-ethynyl-3β-androstanediol, an estrogen, as active metabolites. These metabolites may contribute importantly to the biological activity of 17α-ethynyl-3α-androstanediol, with 17α-ethynyl-3α-androstanediol potentially serving as a prodrug.
Analogues of 17α-ethynyl-3α-androstanediol include 17α-ethynyl-3β-androstanediol, ethinylandrostenediol (17α-ethynyl-5-androstenediol), ethandrostate (17α-ethynyl-5-androstenediol 3β-cyclohexanepropionate), ethinylestradiol (17α-ethynylestradiol), ethisterone (17α-ethynyltestosterone), and 5α-dihydroethisterone (17α-ethynyldihydrotestosterone).
