studies, we demonstrated the use of Marfey’s reagent─a chiral derivatization reagent for amines and phenolic OH groups─for the LC–MS/MS resolution and quantification of amines and amino acid stereoisomers. In this study, a heavy atom isotope labeled Marfey’s reagent approach for the stereoselective detection and quantification of amines and amino acids was developed. Heavy (13C2) l-Marfey’s (Hl-Mar)
生物胺和氨基酸在许多生化过程中发挥着重要作用。生物样品的化学复杂性具有挑战性,胺和氨基酸立体异构体的选择性鉴定和定量对于以胺为重点的“氨基组学”研究非常有用。许多胺和氨基酸是手性的,如果不进行手性衍生化,它们的立体异构体就无法在非手性介质上拆分。在之前的研究中,我们展示了使用 Marfey 试剂(一种胺和酚羟基的手性衍生化试剂)对胺和氨基酸立体异构体进行 LC-MS/MS 分辨率和定量。在这项研究中,开发了一种重原子同位素标记的 Marfey 试剂方法,用于胺和氨基酸的立体选择性检测和定量。由13 C 2 - l -Ala 和2 H 3 - d -Ala 合成重 ( 13 C 2 ) l -Marfey's (H l -Mar) 和重 ( 2 H 3 ) d -Marfey's (H d -Mar),分别。轻质和重质 Marfey 试剂均用于衍生标准胺混合物,并通过 LC-QToF-HRMS

[13C2]-glycine in 15 steps and 2.5% overall yield. With the availability of [13C6]-3,5-dichloroaniline, the sulfonamide [13C6]-(2) was prepared in 12 steps and in 5.6% overall yield. For the carbon-14synthesis, a six-step synthesis gave both compounds [14C]-(1) and [14C]-(2) from the common sulfonyl chloride intermediate [14C]-(15) in 18% and 4% radiochemical yields and specific activities of 44 and 40.5 mCi/mmol
