Four metabolites of the antitumor agent 1-(tetrahydro-2-furanyl)-5-fluorouracil, formed in vitro by rat liver microsomes, were isolated by thin-layer chromatography or high-performance liquid chromatography. On the basis of mass spectrometry, 1H-NMR spectral analysis, and comparison with authentic samples, these metabolites were identified as 1-(trans-4-hydroxytetrahydro-2-furanyl)-5-fluorouracil, 1-(cis-4-hydroxytetrahydro-2-furanyl)-5-fluorouracil, 1-(trans-3-hydroxytetrahydro-2-furanyl)-5-fluorouracil and 1-(4, 5-dehydrotetrahydro-2-furanyl)-5-fluorouracil. These metabolites were also found in the plasma and urine of rats after administration of 1-(tetrahydro-2-furanyl)-5-fluorouracil.
通过薄层色谱法或高效液相色谱法分离了大鼠肝脏微粒体在体外形成的抗肿瘤药物 1-(四氢-2-呋喃基)-5-氟尿嘧啶的四种代谢物。根据质谱、1H-NMR 光谱分析以及与真实样品的比较,确定这些代谢物为 1-(反式-4-羟基四氢-2-呋喃基)-5-氟尿嘧啶、1-(顺式-4-羟基四氢-2-呋喃基)-5-氟尿嘧啶、1-(反式-3-羟基四氢-2-呋喃基)-5-氟尿嘧啶和 1-(4,5-脱氢四氢-2-呋喃基)-5-氟尿嘧啶。大鼠服用 1-(四氢-2-呋喃基)-5-氟尿嘧啶后,其血浆和尿液中也发现了这些代谢物。
