  Design and synthesis of new KRN7000 analogues

  摘要：

  Presented by CD1d protein, KRN7000, a potent synthetic cc-galactosylceramide, is known to stimulate the iNKT cells to produce different bioactive cytokines. Six new KRN7000 analogues, in which the amide bond in KRN7000 is replaced with O, NH, or ester groups incorporating variation of the acyl chain, or possessing an additional four-atom linker between the galactose and phytosphingosine moiety, were designed and synthesized. The synthetic compounds were evaluated for their ability to stimulate cytokine release and the preliminary structure activity relationships were discussed. The synthetic strategy will benefit the construction of more KRN7000 derivatives, which may contribute to cytokine profile bias. (C) 2013 Elsevier Ltd. All rights reserved.

  由d-果糖有效合成d-核糖-C 18-植物鞘氨醇和l-阿拉伯糖-C 18-植物鞘氨醇

  摘要：

  d -核糖-C 18 -phytosphingosine和升-阿拉伯-C 18 -phytosphingosine合成从市售廉价的起始d -fructose。金属介导的断裂和立体选择性还原被用作关键步骤提供的亲水性部分d -核糖和升-阿拉伯phytosphingosines。格拉布斯的交叉复分解和氢化作用使疏水尾部得以结合。

  d-ribo-C18-phytosphingosine and l-arabino-C18-phytosphingosine were synthesised starting from commercially inexpensive d-fructose. Metal-mediated fragmentation and stereoselective reduction were used as key steps to provide the hydrophilic portion of d-ribo and l-arabino phytosphingosines. Grubbs’ cross-metathesis and hydrogenation allowed the incorporation of hydrophobic tail.
