  A PIM2 analogue suppresses allergic airway disease

  摘要：

  Two approaches for the synthesis of a phosphatidylinositol dimannoside (PIM2) analogue 4 that mimics the suppressive activity of natural PIMs and also synthetic PIM2 have been developed. This analogue, where the inositol core was replaced by glycerol, was tested for its ability to suppress cellular inflammation in a mouse model of allergic asthma and shown to be effective in suppressing airway eosinophilia. Suppression of all inflammatory cells monitored was observed, indicating a general blockade of cellular activity. These data indicate that the inositol core is not essential for this suppressive activity. (C) 2010 Elsevier Ltd. All rights reserved.

  phosphatidylinositol (PI) and its dimannosides (PIM2, AcPIM2, and Ac2PIM2) that all possess the predominant natural 19:0/16:0 phosphatidyl acylation pattern were prepared to study their mass spectral fragmentations. Among these, the first synthesis of a fully lipidated PIM (i.e., (16:0,18:0)(19:0/16:0)-PIM2) was achieved from (±)-1,2:4,5-diisopropylidene-d-myo-inositol in 16 steps in 3% overall yield. A key feature

  准备一个均具有主要的天然19：0/16：0磷脂酰酰化模式的天然分枝杆菌磷脂酰肌醇（PI）及其二甘露糖苷（PIM 2，AcPIM 2和Ac 2 PIM 2）家族，以研究其质谱碎裂。其中，完全脂化的PIM（即（16：0,18：0）（19：0/16：0）-PIM 2）的首次合成是由（±）-1,2：4,5实现的-diisopropylidene- d -肌醇肌醇在3％总产率16个步骤。该策略的关键特征是扩展了对-（3,4-二甲氧基苯基）苄基保护基在O上的应用。-3位肌醇允许在合成的后期安装硬脂酰残基。对合成的PIM进行了质谱研究，并将其与从M.的脂质提取物中鉴定出的天然PIM的报道进行了比较。牛眼BCG。这些分析证实，片段化模式可用于从细胞壁脂质提取物中鉴定特定PIM的结构。
