Area of Science:

  • Organic Chemistry
  • Peptide Chemistry
  • Biotechnology

Background:

  • Solid-phase peptide synthesis (SPPS) is a cornerstone of peptide research.
  • Current SPPS methods can be limited in generating complex peptide architectures.
  • Efficient methods for creating peptides with diverse epitope presentations are needed.

Purpose of the Study:

  • To develop a versatile method for synthesizing peptide assemblies with controlled epitope presentation.
  • To explore the use of achiral dicarboxylic acids in peptide coupling strategies.
  • To enable the creation of peptides with multiple N to C and C to N orientations.

Main Methods:

  • Coupling achiral dicarboxylic acids to two peptide chains attached to a synthesis resin.
  • Simultaneous cleavage from the resin and side-chain deprotection.
