Abstract: The retro-enantio analogue of peptide 66--77 of the chemokine MCP-1 and two hexapeptide fragments 66--71 and 72--77 of the C-terminal sequence of this protein were synthesized using the Fmoc strategy of solid phase peptide synthesis. The effect of the synthetic peptides upon the MCP-1--stimulated migration of THP-1 mononuclear cells was studied in vitro. The activity of the retro-enantio analogue was found to be comparable with that of the initial peptide 66--77: both peptides inhibit the migration of monocytes and granulocytes into inflammation zones of experimental animals.
Key words: MCP-1--stimulated cell migration, monocyte, monocyte chemoattractant protein 1 (MCP-1), solid phase peptide synthesis, synthetic peptides, transpeptidation
