本文报道了正常人尿液中5,6-二氢尿苷的鉴定。用硼酸盐凝胶亲和层析和反相高效液相色谱对化合物进行部分纯化和分离,然后用气相色谱/质谱法对其进行表征,确定其为三甲基硅基衍生物。结构证明是基于尿液成分的质谱学和色谱学特征与真实的参考样品的比较。来自高分辨率质量测量和氚同位素标记实验的其他数据证实了碎片离子的结构。还讨论了核苷的高效液相色谱紫外分析中固有的较差的可检测性。
The identification of 5,6-dihydrouridine in normal human urine is reported. Partial purification and isolation of the compound by boronate gel affinity chromatography and reversed-phase high-performance liquid chromatography preceded its characterization as a trimethylsilyl derivative by combined gas chromatography/mass spectrometry. Structure proof is based upon a comparison of mass spectral and chromatographic features of the urinary component to that of an authentic reference sample. Additional data derived from high resolution mass measurements and deuterium isotopelabeling experiments provide confirmation of fragment ion structure. The poor detectability inherent in the HPLC uv analysis of nucleosides is also discussed.
