Synthetic access to three neutral glycosphingolipids from the parasite Schistosoma mansoni adult worm has been achieved. These structures differ significantly from those of other parasites and exhibit a unique structural motif termed “schisto-core” consisting of GalNAcβ1→4Glcβ1→sequence. We have synthesized glycosphingolipids, β-D-GalNAcp-(1→4)-β-D-Glcp-(1→1)Cer (1), β-D-GlcNAcp-(1→3)-β-D-GalNAcp-(1→4)-β-D-Glcp-(1→1)Cer (2) and β-D-Galp-(1→4)-β-D-GlcNAcp-(1→3)-β-D-GalNAcp-(1→4)-β-D-Glcp-(1→1)Cer (3).
