The predictable relationship between beta-amino acid sequence and folding has inspired several biological applications of beta-peptides. For many such applications, it would be desirable to prepare and screen beta-peptide libraries. However, standard peptide synthesis protocols are not efficient enough to support a library approach for many types of beta-peptides. We recently optimized the solid-phase synthesis of beta-peptides using microwave irradiation, and we have now adapted this approach to synthesis on polystyrene macrobeads. We rapidly prepared a high-quality beta-peptide combinatorial library via a split-and-mix strategy. This library was screened in search of beta-peptide antagonists of the p53-MDM2 protein-protein interaction.
