The detection of metabolites of the anti-estrogenic substance cyclofenil, listed on the World Anti-Doping Agency (WADA) Prohibited List since 2004 is described. Target substances are hydroxylated metabolites, bearing an aliphatic hydroxyl group either in the 2-, 3- or 4-position of the aliphatic ring, in addition to the phenolic functions on the aromatic rings. Structural identification used NMR as well as high-resolution mass spectrometry after nano-electrospray ionisation (ESI). Unambiguous detection of all three synthesised cyclofenil metabolites M1M3 was done using gas chromatography for separation and electron ionisation mass spectrometry for detection of the per-silylated compounds in comparison with a reference urine deriving from an excretion study within the WADA 2007 Educational Programme.

介绍了对 2004 年被列入世界反兴奋剂机构(WADA)禁用清单的抗雌激素物质环芬 尼代谢物的检测。目标物质是羟基化的代谢物,除了芳香环上的酚醛功能外,还在脂肪环的 2-、3-或 4-位上带有脂肪族羟基。结构鉴定使用了核磁共振以及纳米电喷雾离子化(ESI)后的高分辨率质谱。使用气相色谱法进行分离,使用电子电离质谱法检测过硅烷化的化合物,并与世界反兴奋剂机构 2007 年教育计划排泄研究中的参考尿液进行比较,从而对合成的所有三种环非尼尔代谢物 M1M3 进行了明确检测。版权所有 © 2008 约翰威利父子有限公司。
