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.

3-Ketosteroid-Delta(1)-dehydrogenase, KsdD(M), was identified by targeted gene disruption and augmentation from Mycobacterium neoaurum NwIB-01, a newly isolated strain. The difficulty of separating 4-androstene-3,17-dione (AD) from 1,4-androstadiene-3,17-dione (ADD) is a key bottleneck to the microbial transformation of phytosterols in industry. This

Modified beta-cyclodextrins have been shown previously to enhance sterol conversion to 4-androstene-3,17-dione (AD) and 1,4-androstadiene-3,17-dione (ADD) by growing Mycobacterium spp. The enhancement effect was mainly attributed to steroid solubilization by the formation of inclusion complexes with modified cyclodextrins. In this

Steroids are a group of organic compounds that include sex hormones, adrenal cortical hormones, sterols, and phytosterols. In mammals, steroid biosynthesis starts from cholesterol via multiple steps to the final steroid and occurs in the gonads, adrenal glands, and placenta.

Microorganisms were isolated from industrial wool scouring effluents and from the soil adjacent to the wastewater treatment lagoon, both sterols-rich environments, in order to search for novel biocatalysts able to transform cholesterol. The isolates were identified on the basis of

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
