General description

1,4-Androstadiene-3,17-dione is a 17-keto anabolic steroid.

Biochem/physiol Actions

1,4-Androstadiene-3,17-dione is a prohormone that converts to an active steroid through the 17bHSD enzyme. 1,4-Androstadiene-3,17-dione is a metabolite of progesterone.
1,4-Androstadiene-3,17-dione is useful in forming pharmaceutically important steroids. Regio- and stereospecific hydroxylation of 1,4-androstadiene-3,17-dione increases its biological activity. Its derivative is also used to produce high-value bile acids. 1,4-Androstadiene-3,17-dione serves as a precursor for the synthesis of progesterone, testosterone, cortisol, estradiol, cortisone, prednisolone, and prednisone.

Current evidence suggests that neo formation of the anabolic steroid boldenone (androsta-1,4-diene-17-ol-3-one) occurs in calves' faecal material, making it difficult to distinguish between illegally administered boldenone and its potential endogenous presence. This strengthens the urgent need to elucidate the pathway
