Abstract
Peptide Leu-Val-Cys-Tyr-Pro-Gln, identical to the bone marrow peptide MP-3, and its Val3and Ser3analogs, lacking SH group, were synthesized by conventional methods of peptide chemistry in solution and, along with the MP-3 S–S-dimerization product, were studied with respect to their effect on the macrophage phagocytic activity. It was shown that the activity was only enhanced by peptide MP-3, which demonstrated the essential role of the SH group in this function. The dimer analog of MP-3, unlike dimer analogs of other monocycteine-containing peptides, glutathione and HP5b, did not exhibit the inhibitory effect.
