Abstract:
... Herein we report the synthesis of 3-aminopropyl glycosides of A (type 2) and B (type 2) tetrasaccharides via [3 + 1] block scheme. Peracetylated trichloroacetimidates of A and B trisaccharides were used as glycosyl donors. The well-known low reactivity of 4-OH group of N-acetyl-d-glucosamine forced us to test four glucosamine derivatives (3-Bz-1,6-anhydro-GlcNAc and 3-trifluoroacetamidopropyl β-gl ...

Abstract:
... Seven lipophilic constructs containing Lewis (Lea, Leb, Ley) or chimeric Lewis/ABH (ALeb, BLeb, ALey, BLey) glycans were obtained starting from corresponding oligosaccharides in form of 3-aminopropyl glycosides. ALeb and BLeb pentasaccharides were synthesized via [3 + 1] blockwise approach. The constructs (neoglycolipids, or FSLs) were inserted in erythrocyte membrane, and obtained “kodecytes” wer ...

Subject:
blood groups; glycosides; humans; trisaccharides
Abstract:
... Blood group A tetrasaccharides of different types have the same terminal trisaccharide fragment that allows using a block scheme in their synthesis. 3-Aminopropyl glycosides of tetrasaccharides GalNAcα1-3(Fucα1-2)Galβ1-3GlcNAcβ (A type 1), GalNAcα1-3(Fucα1-2)Galβ1-3GalNAcα (A type 3), and GalNAcα1-3(Fucα1-2)Galβ1-3GalNAcβ (A type 4) were synthesised using acetylated Galα1-3(Fucα1-2)Gal trichloroac ...
