Multivalent glycopeptides that tightly bind to carbohydrate-binding monoclonal antibody family pgt128

Abstract

The invention relates to a glycopeptide that includes one or more modified amino acid residues having a sidechain comprising a monosaccharide or an oligosaccharide, wherein the glycopeptide binds specifically to a carbohydrate-binding monoclonal antibody from PGT128 family, preferably with an affinity of less than 100 nM. Immunogenic conjugates that include the glycopeptide, and pharmaceutical compositions that include the glycopeptide or the immunogenic conjugate are also disclosed. Various method of using the glycopeptides, immunogenic conjugates, and pharmaceutical compositions are disclosed, including inducing an immune response, inhibiting viral infection, treating a cancerous condition, and detecting a neutralizing antibody.
