摘要: 克林霉素磷酸酯是临床上广泛使用的一种抗菌类药物. 本文对克林霉素磷酸酯进行了1H、13C、31P NMR检测,通过DEPT、1H-1H COSY、13C-1H HSQC、13C-1H HMBC等2D NMR技术对该化合物的1H、13C谱的信号进行了全归属,并结合量子化学计算和NOESY谱证实了化合物的立体结构. 另外,对克林霉素磷酸酯的飞行时间质谱(TOF-MS)的裂解途径进行了分析.

关键词: 克林霉素磷酸酯, NMR, 归属, TOF-MS

Abstract: Clindamycin phosphate, an antibiotic drug, was used extensively in clinic. In this study, the 1H, 13C and 31P chemical shifts of the compound were assigned using 2D NMR techniques, including DEPT, 1H-1H COSY, 13C-1H HSQC and 13C-1H HMBC. The relative stereochemistry was established by the results obtained from quantum chemical calculation and NOESY spectroscopy. The fragmentation pathway of clindamycin phosphate was also analyzed by TOF-MS/MS.

Key words: NMR, clindamycin phosphate, chemical shift assignment, TOF-MS
