Amino Acids and Peptides. XVI. Synthesis of N-Terminal Tetrapeptide Analogy of Fibrin .ALPHA.-Chain and Their Inhibitory Effects on Fibrinogen/Thrombin Clotting.
N-Terminal tetrapeptide analogs of fibrin α-chain were synthesized by the solution method using a new active ester, the ester of the oxime of p-nitroacetophenone, and by the solid-phase method. Their inhibitory effects on fibrinogen/thrombin clotting were examined. Of the synthetic peptides, amide analogs of Gly-Pro-Arg-Pro exhibited a more potent inhibitory effect.

A series of shorter peptide analogues of Bactenecin7 (RP, PRP, GPRP and RPRP) were synthesized and conjugated to 3-(4-oxo-3,4-dihydroquinazolin-2-yl)propanoic acid to study the effect of conjugation. All the peptides and their conjugates were characterized by analytical and spectroscopic techniques. The synthesized compounds viz., peptides, heterocyclic conjugates and the hydrogenolyzed products were
