Synthesis of 2-acetamido-4-O-(2-acetamido-2-deoxy-.BETA.-D-glucopyranosyl)-2-deoxy-3-O-(.ALPHA.-L-fucopyranosyl)-D-glucopyranose (3-O-.ALPHA.-L-fucopyranosyl-di-N-acetylchitobiose).
Synthetic construction of a fucosyl chitobiose as an allergen-associated carbohydrate epitope and the glycopolymer involving highly clustered trisaccharidic sequences
Synthetic construction of fucosyl chitobiose [GlcNAc beta 1 -> 4(Fuc alpha 1 -> 3)GlcNAc] as an allergy-associated carbohydrate epitope was accomplished from three building blocks. The trisaccharidic unit was further transformed into a carbohydrate monomer and polymerization of the glycomonomer proceeded smoothly to provide a series of glycopolymers having various carbohydrate densities. In addition to the organic syntheses, biological evaluations of the glycomonomer and the polymers were carried out and sugar-clustering effects were observed. (C) 2010 Elsevier Ltd.
