In Vitro Metabolism of Doping Agents (Stanozolol, LGD-4033, Anastrozole, GW1516, Trimetazidine) by Human Seminal Vesicle and Liver Fractions.

ABSTRACT: Background: In order to address complex scenarios in anti-doping science, especially in cases where an unintentional exposure of athletes to prohibited substances and a corresponding contamination of doping control samples at the collection event are argued, an understanding of tissue-specific drug metabolism is essential. Hence, in this study, the metabolic capacity of the seminal vesicle using in vitro assays was investigated. Methods: The aim was to assess whether selected doping-relevant substances-stanozolol, LGD-4033, GW1516, trimetazidine, and anastrozole-are metabolised in seminal vesicle cellular fractions (SV-S9) and how that metabolism compares to biotransformations induced by human liver S9 fractions (HL-S9).
