  拥有EPA和DHA在其终端位置反转结构的甘油三酯的合成

  摘要：

  本报告描述了LML型的反转结构的三酰基甘油（标签）的合成，具有纯EPA或DHA位于与纯偶数沿甘油骨架的终端1,3位饱和脂肪酸（C6：0-C16：0 ）占据2位。这些化合物通过包括高度选择性固定化的两步化学酶促合成路线合成南极假丝酵母脂肪酶掺入EPA或DHA激活为丙酮肟酯专门为甘油的1,3-位置。随后通过EDCI偶联剂将饱和的脂肪酰基引入剩余的2-位，以高效地完成标题化合物。这是具有上的长链n-3多不饱和脂肪酸的结构颠倒的标签的第一份报告。可以预期的是，这些新的化合物和它们的合成方法将找到的各种重要的用途，例如分析标准，筛选生物活性和在作为前药制药领域。

• Chemical synthesis and NMR characterization of structured polyunsaturated triacylglycerols

  The chemical synthesis of pure triacylglycerol (TAG) regioisomers, that contain long chain polyunsaturated fatty acids, such as arachidonic acid (AA) or docosahexaenoic acid (DHA), and saturated fatty acids, Such as lauric acid (La) or palmitic acid (P), at defined positions, is described. A single step methodology using (benzotriazol-1-yloxy)-tripyrrolidinophosphonium hexafluorophosphate (PyBOP), an activator of carboxyl group commonly used in peptide synthesis and occasionally used in carboxylic acid esterification, has been developed for structured TAG synthesis. Identification of the fatty acyl chains for each TAG species was confirmed by atmospheric pressure chemical ionisation mass spectrometry (APCI-MS) and fatty acid positional distribution was determined by H-1 and C-13 NMR spectra. The generic described procedures can be applied to a large variety Of Substrates and was used for the production of specific triacylglycerols of defined molecular structures, with high regioisomeric purity. Combination of MS and NMR was shown to be an efficient tool for structural analysis of TAG. In particular. some NMR signals were demonstrated to be regioisomer specific, allowing rapid positional analysis of LC-PUFA containing TAG. (C) 2005 Elsevier Ireland Ltd. All rights reserved.

  EPA or DHA activated as acetoxime esters exclusively into the 1,3-positions of glycerol. The saturated fatty acyl groups were subsequently introduced to the remaining 2-position by EDCI coupling agent to accomplish the title compounds highly efficiently. This is the first report on reversed structured TAGs possessing the long-chain n-3 polyunsaturated fatty acids. It is anticipated that these novel
