  Synthesis and evaluation of immunostimulant plasmalogen lysophosphatidylethanolamine and analogues for natural killer T cells

  摘要：

  Plasmalogen lysophosphatidylethanolamine (pLPE) had been identified as a self antigen for natural killer T cells (NKT cells). It is very important in the development, maturation and activation of NKT cells in thymus. Besides, pLPE is a novel type of antigen for NKT cells. To evaluate the structure-activity relationship (SAR) of this new antigen, pLPE and its analogues referred to different aliphatic chains and linkages at the sn-1 position of the glycerol backbone were synthesized, and the biological activities of these analogues was characterized. It is discovered that the linkages between phosphate and lipid moiety are not important for the antigens' activities. The pLPE analogues 1, 3, 4, 7 and 9, which have additional double bonds on lipid parts, were identified as new NKT agonists. Moreover, the analogues 4, 7 and 9 were discovered as potent Th2 activators for NKT cells. (C) 2014 Elsevier Ltd. All rights reserved.

  立体化学，脂质长度和分支影响单酰基甘油酯的Mincle激动剂活性。

  摘要：

  在这里，我们报道了一系列对映体纯的线性，异支化和α支化单酰基甘油酯（MAGs）的合成，总收率为63-72％。探索了使用NFAT-GFP报告基因细胞通过人巨噬细胞诱导型C型凝集素（hMincle）发出信号的能力，以及化合物激活人单核细胞的能力。从这些研究中，人单核细胞的Mincle激活和白介素8（IL-8）的产生需要酰基链长度≥C22的MAG。此外，与线性MAG相比，异支MAG导致更明显的免疫反应，而含有C-32酰基链的α支MAG则比典型的Mincle激动剂海藻糖二山hen酸酯（TDB）活化细胞的程度更高。在整个复合类别中，sn的活动-1个取代的异构体大于sn -3对应的异构体。代表性化合物均无细胞毒性，因此可减轻细胞毒性，将其作为细胞活性的潜在介质。两者合计，6h（sn -1，iC26 + 1），8a（sn -1，C32）和8b（sn -3，C32）表现出最佳的免疫刺激特性，因此具有作为疫苗佐剂的潜力。

• Pheromone synthesis. Part 253: Synthesis of the racemates and enantiomers of triglycerides of male Drosophila fruit flies with special emphasis on the preparation of enantiomerically pure 1-monoglycerides

  日期：2012.10

  3-ditigloyloxypropyl esters of palmitic, palmitoleic, stearic, oleic, and linoleic acids) of male Drosophila fruit flies were synthesized in three steps from the racemate and enantiomers of 2,3-acetoneglycerol (2) via 1-monoglycerides 4a–e derived from the above fatty acids. Appropriate conditions were established for the preparation of enantiomerically pure 1-monoglycerides 4a–e, and their enantiomeric purities

• Synthesis and hydrolytic stability of cyclic phosphatidic acids: implications for synthetic- and proto-cell studies

  日期：——

  Cyclic phosphatidic acids (cPAs) are bioactive compounds with therapuetic potential, but are in short supply. We describe a robust synthesis of cPAs employing an efficient cyclophosphorylation procedure and report on their hydrolytic properties – which should facilitate the study of their biological properties and as plausible proto- and synthetic-cell components.

• Pheromone synthesis. Part 255: Synthesis and GC–MS analysis of pheromonal triacylglycerols of male Drosophila fruit flies
  作者：Kenji Mori

  DOI：10.1016/j.tet.2014.06.049

  日期：2014.9

  Pheromonal triacylglycerols and their analogs, 1A, 1B, 2A, 2B, 3A, 3B, and 3C, of male Drosophila fruit flies were synthesized and analyzed by GC-MS. Their GC retention times were found to be a reliable measure to analyze and identify these triacylglycerols with acetyl, oleoyl and tigloyl groups, although the stereoand regioisomers of 1 (1A and 1B), 2 (2A and 213), and 3 (3A, 3B, and 3C) could not be distinguished from each other by MS alone.
