Area of Science:

  • Organic Chemistry
  • Polymer Chemistry
  • Materials Science

Background:

  • Polyphenylene dendrimers (PPDs) are known for their shape-persistence and monodispersity.
  • Peptide-dendrimer conjugates hold potential for applications in drug delivery and diagnostics.

Purpose of the Study:

  • To develop synthetic strategies for coupling peptides to polyphenylene dendrimers.
  • To create novel, shape-persistent, polyfunctional multiple antigen conjugates.

Main Methods:

  • Synthesis of functionalized cyclopentadienones.
  • Diels-Alder cycloaddition for PPD synthesis.
  • Three distinct methods for peptide attachment: NCA polymerization, carboxyl-amino coupling, and thiol-maleimide addition.

Main Results:
