A facile synthesis of cyclopeptide-centered multivalent glycoclusters using Cu(I) catalyzed Huisgen 1,3-dipolar cycloaddition of azides and terminal alkynes, so called ‘click chemistry’, has been developed. The affinities of mannose-specific protein Concanavalin A (Con A) toward two synthetic glycoclusters respectively bearing divalent or tetravalent mannoses were investigated by surface plasmon resonance (SPR). It is founded that the tetravalent glycocluster has 3.0-fold increase in binding affinity relative to the divalent glycoluster (valency-corrected values), which indicates the potential of this system in investigating carbohydrate–protein interactions.
