采用液相色谱/串联质谱(LC/MS/MS)联用技术对抗焦虑药和抗高血压药在生物基质中的I相和II相代谢产物进行了鉴定。这些研究表明,碰撞激活解离(CAD)扫描技术,即,产物离子扫描、前体离子扫描和中性丢失扫描对于检测未知代谢物和获得关于代谢物的详细结构信息非常有用。此外,结合代谢物的位置异构体可以通过产物离子扫描分析结合简单的化学衍生来表征。
Combined liquid chromatography/tandem mass spectrometry (LC/MS/MS) were used for the identification of the phase I and phase II (conjugated) metabolites of anxiolytic and antihypertensive drugs in biological matrix. These studies demonstrated that the collisionally activated dissociation (CAD) scan technique, i.e., product ion scan, precursor ion scan, and neutral loss scan, were very useful for detecting the unknown metabolites and for obtaining detailed structural information on the metabolites. Furthermore, the positional isomers of conjugated metabolites could be characterized by product ion scan analysis coupled with simple chemical derivatization.
