  摘要：

  油酸及其磷脂衍生物是细胞膜结构和功能的基础。因此，对于许多核磁共振、红外、质谱和中子散射研究，人们对获得其氘代形式越来越感兴趣。在这里，我们首次提出了一种直接的大规模（克级）合成高度氘代[D32]油酸的方法，该方法使用了多个简单且产率高的反应步骤。合成[D32]油酸的前体是[D14]壬二酸和[D17]壬酸，它们是通过金属催化水热H/D交换反应实现了完全氘化（>98% D）的1H形式得到的。合成的油酸具有约94%的D同位素纯度，并且不含反式异构体（反油酸）污染。此外，还描述了从[D32]油酸合成[D64]二油酰-sn-甘油-3-磷酸胆碱的过程。版权所有©2013 John Wiley & Sons, Ltd.

  Di(2-ethylhexyl) phthalate (DEHP) is a common plasticizer that is largely used for PVC blood bags. The migration of DEHP from medical devices into labile blood products (LBP) is a well-known situation. While DEHP has beneficial effects on the storage of red blood cells, it can have toxicological impact due to its potential reprotoxic effects (classified group 1B). Since July 1st, 2015, the French law prohibits the use of tubing made in DEHP-plasticized PVC in paediatric, neonatal and maternity wards. This provision, which could extend in several years more widely to medical devices used for drugs infusion, dialysis, feeding and blood bags, has led manufacturers to replace DEHP to alternative plasticizers such as diisononylcyclohexane-1,2-dicarboxylate (DINCH). In this paper, a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method has been developed and validated for the determination of DEHP, DINCH and their corresponding monoester metabolites (MEHP and MINCH) in four labile blood products (LBP): whole blood (WB), red cells concentrate (RCC), plasma and platelet concentrate (PC). Due to strong contamination of blank LBP by DEHP because of its ubiquitous presence in working environment and despite the attention paid to avoid contamination of solvents and glassware, a trap chromatographic column was implemented between the solvent mixing chamber and the injector of the LC system. This set-up permitted to discriminate DEHP present in the sample to DEHP brought by the environmental contamination. In the optimized conditions, all compounds were separated in less than 10 min. The analytes were extracted from LBP samples using a liquid-liquid extraction. After optimization, recoveries were ranged from 47 to 96 %, depending on the analytes and the nature of LBP. Except for DEHP which exhibited RSD values of intermediate precision higher than 20 % at a concentration of 25 nM, all the precision results (repeatability and intermediate precision) were lower than 16 % and trueness values ranged from -16.2-19.8%. Using the validated method, the leachability of DEHP and DINCH from corresponding PVC-blood bags was investigated and the concentrations of their corresponding metabolites, MEHP and MINCH, were determined in whole blood, red cells concentrate, plasma and platelet concentrate.

  Oleic acid and its phospholipid derivatives are fundamental to the structure and function of cellular membranes. As a result, there has been increasing interest in the availability of their deuterated forms for many nuclear magnetic resonance, infrared, mass spectroscopy and neutron scattering studies. Here, we present for the first time a straightforward, large-scale (gram quantities) synthesis of highly deuterated [D32]oleic acid by using multiple, yet simple and high yielding reactions. The precursors for the synthesis of [D32]oleic acid are [D14]azelaic acid and [D17]nonanoic acid, which were obtained by complete deuteration (>98% D) of their 1H forms by using metal catalysed hydrothermal H/D exchange reactions. The oleic acid was produced with ca. 94% D isotopic purity and with no contamination by the trans-isomer (elaidic acid). The subsequent synthesis of [D64]dioleoyl-sn-glycero-3-phosphocholine from [D32]oleic acid is also described. Copyright © 2013 John Wiley & Sons, Ltd.
