  • Synthesis of α-Galactosyl Ceramide (KRN7000) and Analogues Thereof via a Common Precursor and Their Preliminary Biological Assessment

    日期:2008.11.21
    practical synthesis of alpha-GalCer and of its analogues is presented, opening the chance to easily modify the sphingosine chain. The common precursor is a disaccharide, obtained by coupling tetra-O-benzyl-D-galactose with allyl 2,3-O-isopropylidene-D-lyxofuranoside. Introduction of alkyl chains via Wittig reaction (for alpha-GalCer and OCH) or via Williamson reaction (for oxa analogues) followed by
    提出了一种新的实用的α-GalCer及其类似物的合成方法,这为轻松修饰鞘氨醇链提供了机会。常见的前体是二糖,其通过将四-O-苄基-D-半乳糖与烯丙基2,3-O-异亚丙基-D-呋喃呋喃糖苷偶联而获得。通过Wittig反应(对于α-GalCer和OCH)或Williamson反应(对于oxa类似物)引入烷基链,然后进行标准合成步骤,可以使人们有效地获得此类化合物。当表达CD1d的细胞呈递时,这些类似物能够激活iNKT细胞。
  • Synthesis and biological evaluation of truncated α-galactosylceramide derivatives focusing on cytokine induction profile

    日期:2012.5
    A series of truncated analogs of alpha-galactosylceramide with altered ceramide moiety was prepared, and evaluated for Th2-biased response in the context of IL-4/IFN-gamma ratio. Phytosphingosine-modified analogs including cyclic, aromatic and ethereal compounds as well as the C-glycoside analog of OCH (2) with their cytokine inducing profile are disclosed.

  • Minimum structure requirement of immunomodulatory glycolipids for predominant Th2 cytokine induction and the discovery of non-linear phytosphingosine analogs
    作者:Tetsuya Toba、Kenji Murata、Kyoko Nakanishi、Bitoku Takahashi、Naohiro Takemoto、Minako Akabane、Takashi Nakatsuka、Seiichi Imajo、Takashi Yamamura、Sachiko Miyake、Hirokazu Annoura
    DOI:10.1016/j.bmcl.2007.02.081
    日期:2007.5
    Analogs of immunomodulatory glycolipid OCH (2) were prepared and minimum structure requirement to exhibit equivalent profiles was disclosed. Analogs bearing non-linear hydrocarbon chain in the phytosphingosine moiety (18, 19) were shown for the first time to possess comparable cytokine inducing profile to 2. Molecular modeling of 2/hCD1d complex based on the crystal structure of alpha-GalCer (1)/hCDld complex is also described. (c) 2007 Elsevier Ltd. All rights reserved.

    A practical and efficient total synthesis of (2S,3S,4R)-1-O-(α-d-galactosyl)-2-tetracosanoylamino-1,3,4-nonanetriol, OCH 1b, a potential therapeutic candidate for Th1-mediated autoimmune diseases, is described. The synthesis incorporates direct alkylation onto epoxide 5 and stereospecific halide ion catalyzed α-glycosidation reaction. A key intermediate 10 was obtained in only eight steps and 37% overall
