  RCAI-61 and related 6′-modified analogs of KRN7000: Their synthesis and bioactivity for mouse lymphocytes to produce interferon-γ in vivo

  摘要：

  We synthesized ten new analogs of 6'-modified KRN7000 (A): RCAI-58, 61, 64, 83, 85-87, 113, 119, and 125. They could be synthesized by alpha-selective galactosylation of ceramide 9 with the 6-modified D-galactopyranosyl fluorides (8a-8f) or L-arabinopyranosyl fluoride (17), or by etherification of the known alcohol 19. Bioassay of the ten analogs demonstrated that RCAI-61 (1, 6'-O-methylated analog of A) was the most potent immunostimulant among them, and could induce the production of a large amount of IFN-gamma even at a low concentration in mice in vivo.

  RCAI-61, the 6'-O-methylated analog of KRN7000, and six other analogs with modified 6'-position of the galactose moiety of KRN7000 were synthesized to examine their bioactivity for mouse lymphocytes. Methyl alpha-D-galactopyranoside was the starting material for RCAI-58, 61, 64, 83, 85, and 86, while RCAI-87 was prepared from methyl beta-L-arabinopyranoside. Bioassay showed RCAI-61 to be a Much more potent stimulant of mouse lymphocytes than KRN7000 and RCAI-56 to induce the production of a large amount of IFN-gamma in vivo. (C) 2008 Elsevier Ltd.
