Multivalent peptoid architectures

Multivalent glycopeptoids (linear and cyclic) are being currently developed to obtain high-affinity ligands for lectin receptors.

Solution-phase synthesis of linear and cyclic β- and α,β-peptoids was coupled to photo-induced thiol–ene coupling (TEC) reactions to readily access multivalent thioglycoclusters. A tetrameric cyclic β-peptoid scaffold displaying 1-thio-β-D-galactose or 1-thio-α-D-mannose has revealed efficient binding potency for bacterial lectins LecA and BC2L-A.
