Analogs of chemotactic peptides (Formyl-Met-X-Phe-OMe) containing the stereochemically constrained residues α-aminoisobutyric acid (Aib), 1-aminocyclopentanecarboxylic acid (Acc5) and 1-aminocyclohexanecarboxylic acid (Acc6) at position 2 are compared with the parent sequence (X=Leu) for their ability to induce lysozyme release in rabbit neutrophils. The Acc6analog is about 78 times more active than the parent peptide, For-Met-Leu-Phe-OH, whereas Aib and Acc5analogs are approximately 3 and 2 times, respectively, less active than the parent peptide. NMR and model building studies clearly favour a Met-Acc6β-turn solution conformation in the Acc6analog, suggesting that the neutrophil receptor is capable of recognizing a folded peptide structure. The significant differences in the activities of the Acc5and Acc6analogs suggest an important role for the residue 2 sidechain in receptor interactions.
