Description:

Androsta-1,4-diene-3,17-dione (ADD) and Androst-4-ene-3,17-dione Androstenedione, AD or 4-AD for short are important intermediates of steroid drugs in Chemicalbook. Androstenedione (4-AD) can not only be used as a precursor of androgen, proprotein synthesis hormone and other hormone substances, but also can be used for the synthesis of spirosteroid, hydrocortisone, prednisone oxide, dexthasone and other drugs. Androdienedione (ADD) can be used in the synthesis of estrogen, oral contraceptives and other drugs.

Androstadienedione (1,4-androstadiene-3,17-dione) is a next generation orally active prohormone. It is a direct precursor to the anabolic steroid boldenone. Boldenone is an anabolic steroid most often found in injectable form as a veterinary medication (boldenone undecylenate). It is chemically a derivative of testosterone. 1,4-androstadiene-3,17-dione converts to estrogen at roughly half the rate of androstenedione and testosterone. This significantly reduces the level of estrogen buildup during use compared to that achieved with testosterone precursors, and similarly also lowers the chance of noticing strong estrogen related side effects such as increased body fat, gynecomastia and definition hiding water retention. Androstadienedione is used as a pharmaceutical intermediate for further synthesis of female sex hormones, hormone replacement therapies and oral contraceptives.

Application:

In this legislation Androstadienedione was classified as a controlled substance and bol-dione remained legal. In April 2008 the United States Drug Enforcement Administration published an "Initial Notice of Proposed Rulemaking" concerning the scheduling of three anabolic substances: bol-dione, desoxymethyltestos-terone, and diene-dione.

4-Androstenedione can be synthesized in one of two ways. The primary pathway involves conversion of 17-hydroxypregnenolone to dehydroepiandrosterone by way of 17,20-lyase, with subsequent conversion of dehydroepiandrosterone to 4-Androstenedione via the enzyme 3-β-hydroxysteroid dehydrogenase. The secondary pathway involves conversion of 17-hydroxyprogesterone, most often a precursor to cortisol, to 4-androstenedione directly by way of 17,20-lyase. Thus, 17,20-lyase is required for the synthesis of 4-androstenedione, whether immediately or one step removed.

The production of adrenal 4-Androstenedione is governed by ACTH, whereas production of gonadal 4-Androstenedione is under control by gonadotropins. In premenopausal women, the adrenal glands and ovaries each produce about half of the total 4-androstenedione(about 3 mg/day). After menopause, 4-androstenedione production is about halved, due primarily to the reduction of the steroid secreted by the ovary. Nevertheless, 4-androstenedione is the principal steroid produced by the postmenopausal ovary.
