Derivatives of glycosides of D-galactosamine were prepared in order to study further the binding requirement of the Gal/GalNAc receptor in mammalian hepatocytes. These structures included N-propanoyl, N-benzoyl, and N,N-phthaloyl derivatives of 2-hydroxyethyl 2-amino-2-deoxy-beta-D-galactopyranoside, 6-amino-hex-1-yl 2-deoxy-2-(trifluoroacetamido)-beta-D-galactopyranoside, the mono- and di-O-methyl
制备D-半乳糖胺糖苷的衍生物是为了进一步研究哺乳动物肝细胞中Gal / GalNAc受体的结合需求。这些结构包括2-羟乙基2-氨基-2-脱氧-β-D-吡喃半乳糖苷,6-氨基-己-1-基2-脱氧-2的N-丙酰基,N-苯甲酰基和N,N-邻苯二甲酰基衍生物。 -(三氟乙酰氨基)-β-D-吡喃半乳糖苷,烯丙基2-乙酰氨基-2-脱氧-β-D-吡喃半乳糖苷和烯丙基2-乙酰氨基-2,4-二甲氧基-4的单和二-O-甲基衍生物-氟-α-D-吡喃半乳糖苷。抑制结果证实了我们先前有关羟基参与的一些发现,并提供了有关N取代基参与以及结合中4-羟基需要氢键的新信息。
