63-05-8 Usage

Uses

Testosterone precursor and metabolite with androgenic activity. Controlled substance (anabolic sterid)

Definition

ChEBI: A 3-oxo Delta4-steroid that is androst-4-ene substituted by oxo groups at positions 3 and 17. It is a steroid hormone synthesized in the adrenal glands and gonads.

Safety Profile

An experimental teratogen. Otherexperimental reproductive effects. Questionablecarcinogen with experimental tumorigenic data. Whenheated to decomposition it emits acrid smoke andirritating fumes.

Chemical Properties

White to Off-White Solid

Biological Metabolism

The in vitro perfusion of the human placental lobule with 7-ethoxycoumarin gives 7-hydroxycoumarin, and perfusion with androstenedione gives the conversion products, estrone, estradiol, and testosterone. The human placenta has only a limited capacity for the metabolism of xenobiotics.

Purification Methods

Crystallise the dione from hexane. It is soluble in *C6H6, CHCl3 and EtOH. It has max at 239nm. It is a precursor of estrone or testosterone and has androgenic activity. [Ruzicka & Wettstein Helv Chim Acta 18 980 1935, Beilstein 7 III 3636, 7 IV 2381.]
