For other types of ligands, e.g. longer nucleotides and peptides, a manually drawn representation of the molecule may be provided. It was reported that Kumar tested positive for a banned substance called anabolic steroid drostanolone metabolite on the day of the race.

A sprinter who ran a 100m final all by himself after his seven rivals fled drug testers has failed a drug test. The 40 year-old rugby player tested positive for the presence of the prohibited substances Drostanolone and Trenbolone (metabolite 17-epitrenbolone).

In continuation of our structural transformation studies on steroidal drugs,14–20 biotransformation of drostanolone heptanoate (1) was carried out. The purpose of this study was to synthesize structurally diverse analogues of drostanolone heptanoate (1) for their potential use in the biomedical research, by employing mild, and low-cost biotransformation procedures. Calculated molecular properties are available for small molecules and natural products (not peptides). All properties were selected to enable the prediction of the Lipinski Rule-of-Five profile or ‘druglikeness’ for each ligand.

The present study reports the biotransformation of an anabolic-androgenic steroid (AAS) drostanolone heptanoate (1) by using two microbial cultures, Beauveria bassiana, and Macrophomina phaseolina. Phaseolina it afforded two new 7–8, and two known 9–10 metabolites. The main sites of hydroxylation in the steroidal skeleton of 1 were at C-5, C-7, C-11, C-14, C-15, and C-20, hydrolysis of the ester moiety at C-17, and reduction of the carbonyl group at C-3. The structures of the transformed products were determined by using mass, NMR, and other spectroscopic techniques.
