Abstract
Glycosyl 1,2,3-triazoles with α-D-gluco, β-D-gluco, α-D-galacto, β-D-galacto and β-2-acetamido-2-deoxygluco (GlcNAc) stereochemistry were prepared by reaction of the corresponding azides with vinyl acetate under microwave irradiation. The deprotected glucosyl and galactosyl triazoles did not display inhibitory activity against the tested glycosidases at 1 mM.
Of the four fungal glycosidases evaluated, GlcNAc-triazole was found to be hydrolyzed by Talaromyces flavus CCF 2686 β-N-acetylhexosaminidase. β-GlcNActriazole was furthermore established to act as a strong ligand of rat and human natural killer cell activating receptors.
