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 GalNAcbeta1-->4Glcbeta1-->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).
已成功实现从曼氏血吸虫成虫中合成三种中性糖鞘脂。这些结构与其他寄生虫的结构有显著差异,并呈现出一种独特的结构基序,称为“血吸虫核心”,由GalNAcbeta1-->4Glcbeta1-->序列组成。我们已经合成了糖鞘脂,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) 和 β-D-Galp-(1-->4)-β-D-GlcNAcp-(1-->3)-β-D-GalNAcp-(1-->4)-β-D-Glcp-(1-->1)Cer (3)。
