摘要

The chemical synthesis of #alpha#L-Fucp-(1 -> 3)-#beta#-D-GalpNAc-(1 -> 4)-#beta#-D-GlcpNAc-(1 -> 3)-#alpha#-D-GlypO(CH_2)_5NH_2, #beta#-D-GalpNAc-(1 -> 4)-[#alpha#-L-Fucp-(1 -> 3)]-#beta#-D-GlcpNAc-(1 -> 3)-#alpha#-D-GalpO(CH_2)_5NH_2, and #alpha#-L-Fucp-(1 -> 3)-#beta#-D-GalpNAc-(1 -> 4)[#alpha#-L-Fucp-(1 -> 3)]#beta#-D-GlcpNAc-(1 -> 3)-#alpha#-D-GalpO(CH_2)_5NH_2 is described. These structures represent fucosylated oligosaccharide fragments of the glycocalyx glycan of the cercarial stage of the parasite Schistosoma mansoni, and in protein-conjugated form they are potential diagnostics in the search for antibodies raised against the glycan in the serum of infected humans.
