Metabolism of anabolic steroids in humans: Synthesis of 6β-hydroxy metabolites of 4-chloro-1,2-dehydro-17α-methyltestosterone, fluoxymesterone, and metandienone
摘要:
Hydroxylation at position 6 beta of testosterone I (17 beta-hydroxyandrost-4-en-3-one) and the anabolic steroids 17 alpha-methyltestosterone II (17 beta-hydroxy-17 alpha-methylandrost-4-en-3-one), metandienone III (17 beta-hydroxy-17 alpha-methylandrosta-1, ,4-dien-3-one), 4-chloro-1,2-dehydro-17 alpha-methyltestosterone IV (4-chloro-17 beta-hydroxy-17 alpha-methylandrosta-1 ,4-dien-3-one), and fluoxymesterone V (9-fluoro-11 beta, 17 beta-dihydroxy-17 alpha-methylandrost-4-en-3-one) was achieved via light-induced autooxidation of the corresponding trimethylsilyl 3,5-dienol ethers dissolved in isopropanol or ethanol. The reaction further yielded the 6 alpha-hydroxy isomer in low amounts. The 6 beta-hydroxy isomers of I-V and the 6 alpha-hydroxy isomers of I, III, and IV were isolated and characterized by H-1 and C-13 NMR, high-performance liquid chromatography, gas chromatography, and mass spectrometry. Human excretion studies with single administered doses of boldenone (17 beta-hydroxyandrosta-1,4-dien-3-one), 4-chloro-1,2 -dehydro-17 alpha-methyltestosterone, fluoxymesterone, metandienone, 17 alpha-methyltestosterone, and [16, 16, 17-H-2(3)]testosterone showed that 6 beta-hydroxylation is the major metabolic pathway in the metabolism of 4-chloro-1,2-dehydro-17 alpha-methyltestosterone, fluoxymesterone, and metandienone, whereas for boldenone, 17 alpha-methyltestosterone, and testosterone, 6 beta-hydroxylation is negligable.

The detection of anabolicandrogenicsteroids (AAS) is one of the most important topics in doping control analysis. Gaschromatographycoupled to (tandem) mass spectrometry (GC–MS(/MS)) with electron ionization and liquid chromatographycoupled to tandem mass spectrometry have been traditionally applied for this purpose. However, both approaches still have important limitations, and, therefore, detection
