  Synthesis and biological evaluation of truncated α-galactosylceramide derivatives focusing on cytokine induction profile

  摘要：

  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.

  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.
