摘要: 利用体内19F NMR研究了5-氟尿嘧啶在小鼠肝脏及植入肿瘤组织中的代谢过程.5-氟尿嘧啶在肝脏中的生物半衰期为15~20min,而在S180肿瘤中的生物半衰期为50-60min.除5-氟尿嘧啶的信号外.在肝脏中观测到了5-氟尿嘧啶的分解代谢产物FUPA和FBAL,而在肿瘤中则只有合成代谢产物氟代核苷酸的信号.实验结果表明,核磁共振是研究药物在体内代谢过程的有力方法.

Abstract: Metabolism of 5-fluorouracil(5FU) in mouse liver and implanted S180 tumor was studied using in vivo 19F NMR spectroscopy. The half-life of 5FU elimination is about 15-20min in liver and 50-60min in tumor.Catabolites of 5FU,fluorouredopropanic acid and α-fluoro-β-analine,were observed in livel, while only the fluoronucleotides,anabolites of 5FU,were observed in tumor. The results show that NMR spectroscopy is a powerful method for metabolic and pharmacokinetic studies.
