Abstract
The three analogues with D-amino acid substituents at position 1 and 5 of PRP-hexapeptide were synthesized and tested for its biological activity to check the influence of the spacial orientation of aromatic rings on the immune response. One of the analogs (Tyr-Val-Pro-Leu-D-Phe-Pro) was found to have the immunoregulatory activity.
