Androsterone
|
A metabolite of androgen. A male hormone isolated from adult male urine by AFJ Butenandt et al. (1934). Colorless crystals with a melting point of 185-185.5°C. It is sparingly soluble in water but readily soluble in most organic solvents. It is the standard substance for the international unit of male hormone activity, with 1 international unit being the increase in the comb area of a castrated rooster caused by 0.1 mg of it. Its biological activity is about one-tenth that of testosterone. It was synthesized from cholesterol by LS Ruzicka et al. (34) and its structure was determined.
