摘要

基于在毒理学相关生长促进剂领域的选定实例,描述了LC-MS/MS在动物异种代谢途径鉴定中的应用。复杂生物基质中外源代谢物的结构阐明使用各种分析方法和策略,使用LC-MS与ESI或APCI电离技术,结合内部CAD或MS/MS实验。使用一些特殊的分析工具(例如H/D交换或MSn多序列实验)来解决特定的结构歧义也进行了讨论。

Use of LC-MS/MS for xenobiotic metabolism studies in animals
The use of LC-MS/MS in the identification of xenobic metabolism pathawys in animals is described, on the basis of selected examples in the field of toxixologically relevant growth promoting agents. The structural elucidation of xenobiotic metabollites in complex biological matrices is archieved using various analytical methods and strategies using LC-MS with ESI or APCI ionisation techniques in combination with in-source CAD or MS/MS experiments. The use of some particular analytical tools (e.g. H/D exchange or MSn multisequential experiments) for solving specific structural ambiguities is also discussed.
