The 8-methoxycarbonyloctyl glycosides of GlcNAcβ, Galβ1-4Glcβ, Fucα1-2Fucα1-3GalNacβ and Fucα1-2Galβ1-3[Fucα1-4]GlcNacβ were converted to primary amines by reaction with neat ethylenediamine and then coupled to bovine serum albumin (BSA) using diethyl squarate as the connector. The average degree of incorporation of the sugar onto the protein, as well as(More)
We report the chemical synthesis of alphaFuc(1-->2)alphaGal-O(CH2)7CH3 (1) an analog of the natural blood group (O)H disaccharide alphaFuc(1-->2)betaGal-OR. Compound 1 was a good substrate for recombinant blood group B glycosyltransferase (GTB) and was used as a precursor for the enzymatic synthesis of the blood group B analog(More)
The Pk-trisaccharide, linked to a solid carrier, is a potential agent for neutralization of shiga-like toxin in the gastrointestinal tract. Two approaches to the multigram-scale synthesis of a linkable Pk-trisaccharide derivative were therefore investigated. A four-step chemical synthesis yielded 8-methoxycarbonyloctyl beta-lactoside in 75% yield from(More)
We report the chemical synthesis of αFuc(1→2)αGal-O(CH2)7CH3 (1) an analog of the natural blood group (O)H disaccharide αFuc(1→2)βGal-OR. Compound 1 was a good substrate for recombinant blood group B glycosyltransferase (GTB) and was used as a precursor for the enzymatic synthesis of the blood group B analog αGal(→3)[αFuc(1→2)]αGal-O(CH2)7CH3 (2).
