Abstract

A DNA-encoded macrocyclic peptide library was designed and synthesized with 2.4 × 1012 members composed of 4–20 natural and non-natural amino acids. Affinity-based selection was performed against two therapeutic targets, VHL and RSV N protein. On the basis of selection data, some peptides were selected for resynthesis without a DNA tag, and their activity was confirmed.
