  Metabolism of 4-hydroxyandrostenedione and 4-hydroxytestosterone: Mass spectrometric identification of urinary metabolites

  摘要：

  4-Hydroxyandrost-4-ene-3,17-dione is a second generation, irreversible aromatase inhibitor and commonly used as anti breast cancer medication for postmenopausal women. 4-Hydroxytestosterone is advertised as anabolic steroid and does not have any therapeutic indication. Both substances are prohibited in sports by the World Anti-Doping Agency, and, due to a considerable increase of structurally related steroids with anabolic effects offered via the internet, the metabolism of two representative candidates was investigated.Excretion studies were conducted with oral applications of 100mg of 4-hydroxyandro-stenedione or 200mg of 4-hydroxytestosterone to healthy male volunteers. Urine samples were analyzed for metabolic products using conventional gas chromatography-mass spectrometry approaches, and the identification of urinary metabolites was based on reference substances, which were synthesized and structurally characterized by nuclear magnetic resonance spectroscopy and high resolution/high accuracy mass spectrometry.Identified phase-I as well as phase-II metabolites were identical for both substances. Regarding phase-I metabolism 4-hydroxyandrostenedione (1) and its reduction products 3 beta-hydroxy-5 alpha-androstane-4,17-dione (2) and 3 alpha-hydroxy-5 beta-androstane-4,17-dione (3) were detected. Further reductive conversion led to all possible isomers of 3 xi,4 xi-dihydroxy,-5 xi-androstan-17-one (4, 6-11) except 3 alpha,4 alpha-dihydroxy-5 beta-androstan-17-one (5).Out of the 17 beta-hydroxylated analogs 4-hydroxytestosterone (18), 3 beta,17 beta-dihydroxy-alpha-androstan-4-one (19),3 alpha,17 beta-dihydroxy-5 beta-androstan-4-one (20), 5 alpha-androstane-3 beta,4 beta,17 beta-triol (21), 5 alpha-androstane-3 alpha,4 beta,17 beta-triol (26) and 5 alpha-androstane-3 alpha,4 alpha,17 beta-triol (28) were identified in the post administration urine specimens. Furthermore 4-hydroxyandrosta-4,6-diene-3,17-dione (29) and 4-hydroxyandrosta-1,4-diene-3,17-dione (30) were determined as oxidation products. Conjugation was diverse and included glucuronidation and sulfatation. (c) 2006 Elsevier Inc. All rights reserved.
