摘要
目的建立美洛西林钠化学结构的确证方法。方法通过热分析(TA)、元素分析(EA)、紫外吸收光谱(UV)、红外吸收光谱(IR)、核磁共振(NMR)以及质谱(MS)等分析手段对美洛西林钠样品进行结构分析。结果证实了美洛西林钠的结构为(2S,5R,6R)-3,3-二甲基-6-[(2R)-[3-(甲磺酰基)-2-氧代-1-咪唑烷甲酰氨基]-2-苯乙酰氨基]-7-氧代-4-硫杂-1-氮杂双环[3.2.0]庚烷-2-甲酸钠盐。结论该方法准确可行,可为美洛西林钠的生产和鉴定提供较全面的参考依据。
OBJECTIVE To establish a method for the determination of the chemical structure of mezlocillin sodium. METHODS Thermal analysis(TA), elemental analysis(EA), ultraviolet absorption spectrum(UV), infrared Fourier transform spectroscopy(FT-IR), nuclear magnetic resonance(NMR) and mass spectrometry(MS) were adopted to analyze the chemical structure of mezlocillin sodium. RESULTS The chemical structure of mezlocillin sodium was (2S,5R,6R)-3,3-dimethyl-6- [[(R)-2-[(3-methylsulfonyl-2-oxo-imidazolidin- 1-yl)carbonylamino]-2-phenyl-acetyl] amino]-7-oxo-4-thia- 1-azabicyclo[3.2.0] heptane -2-carboxylic acid sodium salt. CONCLUSION The result of the method is accurate, general and can provide a comprehensive reference for production and identification of mezlocillin sodium.
