The novel cyclic analogues cyclo(Phe-Leu-Leu-Arg-epsilonLys-Dap) (1) and cyclo(D-Phe-Leu-Leu-Arg-epsilonLys-Dap) (2), which differ only in the absolute conformation of Phe, have been designed and synthesized based upon the minimal peptide sequence Phe-Leu-Leu-Arg which has been found to exhibit biological activity for the thrombin receptor. Compound 1, in which all amino acids have the L-configuration
