development process of new pharmaceutical drugs. Liquid Chromatography (LC) in combination with Mass Spectrometry (MS) is usually the technique of choice for structural identification but cannot always provide precise structural identification of the studied metabolite (e.g. site of hydroxylation and site of glucuronidation). In order to identify those metabolites, different approaches are used combined
代谢物的结构阐明是新药物开发和发现过程中的重要组成部分。液相色谱(LC)结合质谱(MS)通常是结构鉴定的首选技术,但不能始终提供所研究代谢物的精确结构鉴定(例如,羟基化位点和葡萄糖醛酸化位点)。为了鉴定这些代谢物,将不同的方法与MS数据结合使用,包括核磁共振,氢/氘交换和化学衍生化,然后进行LC-MS。这些技术通常很耗时,并且/或者需要额外的样品预处理。
