Peptide analogs in which one or more amino acids is replaced by a diaza- or triazacyclohexenone, or by an aza-, diaza-, or triazacyclohexenone that is substituted at the α-position with a side chain of an amino acid, display an improved ability to assume a β-strand conformation and to enter into β-sheet-like interactions with peptides in an affinity-specific manner. The peptide analogs of this invention therefore have utility as β-strand mimics offering advantages over both native peptides and β-strand mimics of the prior art.
