  A formyl peptide substituted with a conformationally constrained phenylalanine residue evokes a selective immune response in human neutrophils

  摘要：

  Formyl-Met-Leu-Phe-OH (fMLP) binds to formyl peptide receptors, FPR1 and FPR2, and evokes migration and superoxide anion production in human neutrophils. To obtain a more effective and selective ligand, fMLP analogs in which the Phe residue was substituted with four isomers of cyclopropanephenylalanine were synthesized. While Z-isomer peptides induced both migration and superoxide anion production, E-isomer peptides elicited only chemotaxis. Homologous receptor desensitization experiments revealed that E-isomer peptides bound to FPR2. Although a selective agonist of chemotaxis also binds to FPR2 without increasing intracellular calcium concentration, E-isomer peptide elevated the concentration to the same level as fMLP. Understanding of mechanisms responsible for the selectivity of the reported selective agonists and rPhe-substituted analogs should prove useful for revealing the relationship between receptor-ligand interactions and biological responses of human neutrophils.

  to]dirhodium. The carbenoid structure has a critical effect on the degree of asymmetric induction, and the combination of a small electron-withdrawing group such as a methyl ester and an electron-donating group such as vinyl or phenyl resulted in the highest levels of enantioselectivity. The use of electron neutral alkenes and pentane as solvent also enhanced the enantioselectivity of the process.

  E selectivity, while reactions in the presence of meso-tetraphenylporphyrin iron chloride gave predominantly the corresponding Z isomers. The synthetic utility of this process was demonstrated in the synthesis of (+/-)-(Z)-2,3-methanophenylalanine [(+/-)-(Z)-1], the anti-Parkinson (+/-)-(E)-2,3-methano-m-tyrosine [(+/-)-(E)-2], and the natural product (+/-)-coronamic acid [(+/-)-3].
