Definition

ChEBI: Adrenosterone is a 3-oxo Delta(4)-steroid that is androst-4-ene carrying three oxo-substituents at positions 3, 11 and 17. It has a role as an androgen, a human urinary metabolite, a marine metabolite and an EC 1.1.1.146 (11beta-hydroxysteroid dehydrogenase) inhibitor. It is a 3-oxo-Delta(4) steroid, a 17-oxo steroid, an androstanoid and an 11-oxo steroid. It derives from a hydride of an androstane.

Benefits

Adrenosterone is sold as a dietary supplement since 2007 as a fat loss and muscle gaining supplement. It is thought to be a competitive selective 11βHSD1 inhibitor, which is responsible for activation of cortisol from cortisone. Thus preventing muscle breakdown, and contributing to a majority of its effects.

Purification Methods

Dissolve adrenosterone i n Me2CO, decolorise it with charcoal, filter, add H2O, Me2CO evaporate and the solid is recrystallised from aqueous EtOH. Also recrystallise it from Et2O or Et2O/pentane and dry it at 110o/0.1mm for 2hours. It can be sublimed under high vacuum. [Reichstein Helv Chim Acta 20 953, 979 1937, Mason et al.
