Popis: The automated Fmoc solid-phase technique was used to synthesize Cys-containing linear peptide fragments of monocyte chemoattractant protein-1, chemokine domain of fractalkine, and their analogues, with the Cys residue being either modified or replaced with Ser. Chimeric symmetric and asymmetric disulfides were also prepared from the linear precursors. A SAR study of a set of the newly synthesized peptides showed that the capacity to stimulate migration of monocytes and influence cell motility in vitro critically depends, in general, on the presence of free Cys thiol group in the molecule. Notably, all analogues, including chimeric disulfides, containing no SH groups demonstrated the lack of chemokinetic properties.
