  Synthesis and Evaluation of Sphinganine Analogues of KRN7000 and OCH

  摘要：

  The phytosphingosine-containing alpha-galactosylceramides (alpha-GalCers), KRN7000 and OCH, have been shown to activate NKT cells via interaction with CD1d, a member of the CD1 family of antigen presenting proteins. Evidence from KRN7000 stimulation of NKT cells suggests that alpha-GalCers may have applications in the treatment or prevention of a range of viral, bacterial, and autoimmune conditions. Moreover, OCH, a truncated analogue of KRN7000, appears to induce a T(H)2 bias, which could have implications for the treatment of autoimmune and inflammatory conditions. We have prepared the direct sphinganine-containing analogues of KRN7000 and OCH, 1 and 2, and found them to be comparable in activity to the parent compounds in inducing the release of IL-2, IL-4, and IFN gamma. In addition, compound 2 leads to a cytokine bias similar to that seen with OCH. This is significant because sphinganines are more easily accessed than phytosphingosines, which should facilitate SAR studies.

  An alpha-galactosyl ceramide (alpha-GalCer) 2 was synthesized and evaluated for its ability to stimulate iNKTcell proliferation and elicit T-helper cytokines, IL-4 and IFN gamma. Compound 2 combines the acyl chain of the potent, Th2 biasing alpha-GalCer 1 with a sphingoid base of the same length as that found in OCH, which also exhibits Th2 skewing, Such complementation may enhance cytokine bias, which is thought to be important for therapeutic applications of iNKT cell stimulation. Two related alpha-GalCers, 3 and 4, with saturated acyl chains were prepared for comparison. (C) 2009 Elsevier Ltd. All rights reserved.
