Abstract

d-Amino acid containing peptides are promising as drug lead compounds because of their expected higher stability in vivo. A heterochiral random peptide library called the one-bead–2n-peptide (OB2nP) library, which can display 2n peptide diastereomers per bead, has been developed. Through screening of the OB2nP library and subsequent binding assay among the peptide diastereomers synthesized in parallel by means of the SPOTs method, new heterochiral mimotopes for the anti-β-endorphin monoclonal antibody have been obtained. One mimotope was a new ligand for the μ-opioid receptor. The screening strategy enabled d-amino acid containing drug leads to be obtained efficiently by expanding searchable chemical space without increasing the experimental scale.
