Formyl peptide chemoattractants. Synthesis and chemotactic activity.
The tetrapeptides CHO-Met-Leu-Phe-CO-NH-(CH2)n-COOMe (n = 1-5) have been synthesized. These peptides containing an omega-amino acid residue in position 4 exhibit a very high chemotactic activity. Like the chemotactic peptide CHO-Met-Leu-Phe-OMe, these tetrapeptides in solution undoubtedly adopt an "active" conformation which allows a strong interaction with the receptor on the human polymorphonuclear leukocyte surface.
