  Synthesis and biological evaluation of α-galactosylceramide (KRN7000) and isoglobotrihexosylceramide (iGb3)

  摘要：

  Glycoceramides call activate NKT cells by binding with CD1d to produce IFN-gamma, IL-4, and other cytokines. An efficient synthetic pathway for alpha-galactosylceramide (KRN7000) was established by coupling a protected galactose donor to a properly protected ceramide. During the investigation, it was discovered that when the ceramide was protected with benzyl groups, only beta-galactosylceramide was produced from the glycosylation reaction. In contrast, the ceramide with benzoyl protecting groups produced alpha-galactosylceramide. Isoglobotrihexosylceramide (iGb3) was prepared by glycosylation of Gal alpha 1-3Gal beta 1-4Glc donor with 2-azidosphingosine in high yield. Biological assays on the synthetic KRN7000 and iGb3 were performed using human and murine iNKT cell clones or hybridomas. (C) 2006 Elsevier Ltd. All rights reserved.

  Agelasphin-9b, (2S,3S,4R)-1-O-(alpha-D-galactopyranosyl)-16-methyl-2-[N-((R)-2-hydroxytetracosanoyl)-amino]-1,3,4-heptadecanetriol, is a potent antitumor agent isolated from the marine sponge Agelas mauritianus. Various analogues of agelasphin-9b (a lead compound) were synthesized, and the relationship between their structures and biological activities was examined using several assay systems. From the results, KRN7000, (2S,3S;4R)-1-O-(alpha-D-galactopyranosyl)2-(N-hexacosanoylamino)-1,3,4-octadecanetriol, was selected as a candidate for clinical application.
