  A new sulphate metabolite as a long-term marker of metandienone misuse

  摘要：

  Metandienone is one of the most frequently detected anabolic androgenic steroids in sports drug testing. Metandienone misuse is commonly detected by monitoring different metabolites excreted free or conjugated with glucuronic acid using gas chromatography mass spectrometry (GC-MS) and liquid chromatography tandem mass spectrometry (LC-MS/MS) after hydrolysis with beta-glucuronidase and liquid-liquid extraction. It is known that several metabolites are the result of the formation of sulphate conjugates in C17, which are converted to their 17-epimers in urine. Therefore, sulphation is an important phase II metabolic pathway of metandienone that has not been comprehensively studied. The aim of this work was to evaluate the sulphate fraction of metandienone metabolism by LC-MS/MS. Seven sulphate metabolites were detected after the analysis of excretion study samples by applying different neutral loss scan, precursor ion scan and SRM methods. One of the metabolites (M1) was identified and characterised by GC-MS/MS and LC-MS/MS as 18-nor-17 beta-hydroxymethyl-17 alpha-methylandrost-1,4,13-triene-3-one sulphate. M1 could be detected up to 26 days after the administration of a single dose of metandienone (5 mg), thus improving the period in which the misuse can be reported with respect to the last long-term metandienone metabolite described (18-nor-17 beta-hydroxymethyl-17 alpha-methylandrost-1,4,13-triene-3one excreted in the glucuronide fraction).

  17种β-羟甲基-17α-甲基-18-norandrost-13-烯类甾醇的基于CH乙氧基化的化学合成

  摘要：

  在具有独特的17β-羟甲基-17a-甲基-18-nor-13-烯D片段的类固醇的第一个化学合成中，钯催化的CH乙酰氧基化已被提议作为关键转化。此CH功能化步骤对于反转易于获得的合成中间体的四级立体中心的构型至关重要。所开发的方法被用于制备抗兴奋剂分析中作为参考物质所需的甲氧萘醌代谢物，以控制这种雄激素合成代谢类固醇的滥用。

  product in a single hydroxylation step. The obtained results demonstrate that CYP21 and to a lesser extent also CYP3A4 expressing strains can catalyze this steroid hydroxylation. Subsequent 5 l-scale fermentation resulted in the production and purification of 10 mg of metabolite and its unequivocal structure determination via NMR.

  摘要 合成代谢雄激素类固醇是人类运动中最常被误用的药物之一。最近，通过 LC-MS/MS 和 GC-发现了一种以前未知的甲二烯酮尿代谢物 17β-羟甲基-17α-甲基-18-norandrosta-1,4,13-trien-3-one (20OH-NorMD)。小姐。据报道，在服用美二烯酮后长达 19 天的尿样中可检测到这种代谢物。然而，到目前为止，还无法获得该代谢物的纯化参考物质并通过 NMR 确认其结构。筛选了表达不同人类肝脏或类固醇细胞色素 P450 酶的裂殖酵母粟酒裂殖酵母的 11 种重组菌株，以在全细胞生物转化反应中生产这种代谢物。17,17-Dimethyl-18-norandrosta-1,4,13-trien-3-one，化学衍生自美二烯酮，被用作生物转化的底物，因为它可以在单个羟基化步骤中转化为最终产物。获得的结果表明CYP21和在较小程度上还有CYP3A4表达菌株可以催化这种类固醇羟基化。随后的

  The goal of this work was a good-yielding chemical synthesis of a metandienone metabolite which is of interest in doping analysis. 20 beta OH-NorMD (IUPAC: 17 beta-hydroxymethyl-17 alpha-methyl-18-norandrosta-1,4,13-triene-3-one) has been identified as a long-term urinary metabolite which can be detected and attributed to metandienone up to almost 3 weeks after exposure. The chemical synthesis of its epimer 20 alpha OH-NorMD has been described before, as was an enzymatic synthesis of 20 beta OH-NorMD, but no chemical synthesis was published. (C) 2016 Elsevier Inc.
