| Androstenedione Usage And Synthesis | |
|---|---|
| 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. |
| Chemical Properties | White to Off-White Solid |
| 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. |
| 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.] |
