Abstract:
A series of di- and tripeptides containing aspartic or asparagine as N-terminal or intermediate amino acid were synthesized and tested for their effect on human platelet aggregation in vitro. It was found that only Met-Asp(or Asn)-Phe-NH2 inhibited platelet aggregation induced by collagen, ADP or adrenaline. Asn-Phe-NH2 and to a small extent Asp-Phe-NH2 presented strong aggregatory activity at low concentrations (at 0.5 mM or lower than this). All the other peptides tested, did not show any effect on platelet aggregation even at the concentration of 10 mM.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
