Branched Peptide
Branched Peptide — A peptide with one or more side chain branch points where additional peptide chains extend, used to increase valency and binding avidity.
What Is a Branched Peptide?
A branched peptide has one or more peptide chains extending from side-chain functional groups (typically Lys epsilon-amine or Glu/Asp side-chain carboxyl) of the main chain, creating a tree-like architecture. Branched designs are used for multivalent display (multiple copies of a targeting peptide) and as multiple antigenic peptides (MAP) for immune stimulation.
Types
- MAP (multiple antigenic peptide): 4-8 copies of an epitope on a Lys dendrimer core for vaccine immunization
- Multivalent targeting: 2-4 copies of a receptor-binding peptide for enhanced avidity
- Synthesis: Sequential deprotection of orthogonal protecting groups on branch-point Lys residues
