摘要:
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 GalNAc beta 1 -> 4Glc beta 1 -> sequence. We have synthesized glycosphingolipids, beta-D-GalNAcp-(1 -> 4)-beta-D-Glcp-(1 -> 1)Cer (1), beta-D-GlcNAcp-(1 -> 3)-beta-D-GalNAcp-(1 -> 4)-beta-D-Glcp-(1 -> 1)Cer (2) and beta-D-Galp-(1 -> 4)-beta-D-GlcNAcp-(1 -> 3)-beta-D-GalNAcp-(1 -> 4)-beta-D-Glcp-(1 -> 1)Cer (3).
