  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.

  A concise synthesis of (3S,4S,5R)-1-(α-d-galactopyranosyl)-3-tetracosanoylamino-4,5-decanediol, a C-glycoside analogue of immunomodulating α-galactosylceramide OCH

  摘要：

  A concise and convergent synthesis of the C-glycoside analogue 2b of immunomodulating alpha-galactosylceramide OCH 1b starting from readily available 2,3,4,6-tetra-O-bensyl-D-galactose 3 and L-arabinose 6 is described. The synthesis features the nucleophilic addition of an alpha-ethynyl sugar 5 to the phytosphingosine-precursor aldehyde 9 and would be applicable to a variety of C-glycoside analogues of interest.
