Abstract

The relative position of the Asp and Trp residues in a peptide chain is important for recognizing a tetraguanidinium receptor through hydrogen bonding and cation-π interactions. The molecule not only binds with high affinity (K_a = 1.1 x 10⁸M^-1), it also stabilizes the helical schematic representation) as demonstrated by NMR and CD spectroscopy.
