大鼠尿液中N-氧化烟酰胺和伪尿嘧啶核苷的NMR分析

N-氧化烟酰胺和伪尿嘧啶核苷是尿液代谢组的两种重要组成成分,但是其核磁共振信号的归属仍不完善。该文采用多种2D NMR谱(1H-1H COSY,1H-1H TOCSY,1H-1H J-RES,1H-13C HSQC和1H-13C HMBC)对尿液中N-氧化烟酰胺和伪尿嘧啶核苷的结构进行了确定,并对其1H和13C的化学位移进行了归属。...

Nicotinamide N-oxide and pseudouridine are two important metabolites in rat urine. In this studies, the 1H and 13C NMR signals from these two metabolites were assigned using a series of two-dimensional (2D) NMR spectra including 1H-1H COSY, 1H-1H TOCSY, 1H-1H J-RES, 1H-13C HSQC and 1H-13C HMBC.
