title: Synthesis of plasmin substrates and relationship between their structure and plasmin activity.
abstract: The plasmin substrates, D-Ile-Phe-Lys-pNA (I), 3-MV-Phe-Lys-pNA (II), Ile-Phe-Lys-pNA (III), D-Pro-Phe-Lys-pNA (IV), CP-Phe-Lys-pNA (V) and Pro-Phe-Lys-pNA (VI), were synthesized by the conventional solution method and the kinetic parameters of their amidolysis by plasmin were determined. It was found that the free amino group of the D-amino acid in substrates (I) and (IV) made a contribution to an increment in affinity between the substrate and plasmin.
