    Defluorinated Sparfloxacin as a New Photoproduct Identified by Liquid Chromatography Coupled with UV Detection and Tandem Mass Spectrometry
    摘要:
    通过高压液相色谱联合紫外检测和液相色谱联合紫外检测和串联质谱(LC-MS/MS),观察到了斯帕氟沙星的光降解。检测到了三种产物。与独立合成的斯帕氟沙星衍生物进行比较,揭示了其中一种产物的结构,被认为是8-去氟斯帕氟沙星。第二种产物可能是通过氟和环丙基环的分裂形成的。因此,第一次通过LC-MS/MS发现并证明了喹诺酮抗菌剂的光去氟作用。
