在疑似2,4-二硝基苯酚(DNP)致命中毒的尸检案例中,对收集的生物流体(血液、尿液、胃内容物和胆汁)进行了液相色谱-串联质谱(LC-MS-MS)分析,从而确定了DNP及其已知代谢物(2-氨基-4-硝基酚和硝基-4-氨基酚)。基于它们的伪分子离子、同位素和裂解模式以及保留特性,可以初步鉴定出三种结合代谢物(DNP葡萄糖苷酸、DNP硫酸盐和2-氨基-4-硝基酚葡萄糖苷酸)。在文献中报道的另一种DNP代谢物,2,4-二氨基酚,在样品中未检测到。尸检血液中DNP的浓度为48.4 mg/L,2-氨基-4-硝基酚的浓度为1.2 mg/L。...
A liquid chromatography-tandem mass spectrometry (LC-MS-MS) analysis of biological fluids (blood, urine, gastric content, and bile) collected at autopsy in a case of suspected 2,4-dinitrophenol (DNP) fatal poisoning allowed the determination of DNP and its known metabolites (2-amino-4-nitrophenol and nitro-4-aminophenol). The tentative identification of three conjugated metabolites (DNP glucuronide, DNP sulfate, and 2-amino-4-nitrophenol glucuronide) could be made on the basis of their pseudomolecular ion, isotopic and fragmentation patterns, and retention characteristics. Another DNP metabolite reported in the literature, 2,4-diaminophenol, was not detected in the samples. Postmortem blood concentrations were 48.4 mg/L for DNP and 1.2 mg/L for 2-amino-4-nitrophenol. ...
