Abstract

$Formyl-Met-Leu-{\Delta}^z-Phe-Ome$, an analog of the chemotactic tripeptide Formyl-Met-Leu-Phe has been synthesized to evaluate the effect of substitution of \alpha, \beta-dehydrophenylalanine on activity and conformation. The analog peptide shows high biological activity in stimulating superoxide production by rabbit neutrophils. An NMR analysis of the solution conformation of the ${\Delta}^z-Phe$ analog, using nuclear Overhauser effects and comparisons with the corresponding saturated peptides, favours a significant population of extended backbone conformations.
