Abstract

A series of novel glycopyranosyl azides were synthesised wherein the carbohydrate moiety was peracylated with four acetyl, propionyl, butanoyl, pentanoyl (valeryl) or 3-methylbutanoyl (isovaleryl) ester linked groups. A panel of glycoconjugates was synthesised from these glycopyranosyl azides using copper-catalysed azide-alkyne cycloaddition. The in vitro metabolic stability, plasma stability and plasma protein binding was then measured to establish the impact of the different acyl group when presented on a common scaffold. The acetyl, propionyl and butanoyl esters exhibited metabolism consistent with esterase processing, and various mono-, di- and tri-acylated hydrolysis products as well as the fully hydrolysed compound were detected. In contrast, the pentanoyl and 3-methylbutanoyl esters were stable.
