<unk> , also known as androst-5-ene-3β,17β-diol, is a naturally occurring androstane steroid. It is closely related structurally to<unk> e (A4; androst-4-ene-3,17-dione), dehydroepiandrosterone (DHEA; androst-5-en-3β-ol-17-one), and testosterone (androst-4-en-17β-ol-3-one), as well as to 3β-androstanediol (5α-androstane-3β,17β-diol). Derivatives and analogues of<unk> , such as the 17α-substituted methandriol (17α-methylandrostenediol) and ethinylandrostenediol (17α-ethynylandrostenediol) as well as the naturally occurring 19-norandrostane derivative norandostenediol (19-nor-5-androstenediol), have been synthesized and studied. Methandriol and its esters are androgens and anabolic steroids while ethinylandrostenediol is an estrogen.
