  Four cyclic analogues of the C-terminal hepta- or hexapeptide of substance P were prepared by the solution method. The cyclizations were obtained by substituting with cysteine the residues normally present in positions 5 or 6 or 11 of substance P and by subsequent disulfide bond formation. The final products were identified by ordinary analytical procedures and advanced mass spectroscopy. The biological activities were determined on three bioassays: the guinea pig ileum, the guinea pig trachea and the rabbit mesenteric vein. Results obtained with these assays indicate that all peptides with a disulfide bridgehead in position 11 are inactive and that a cycle between positions 5 and 6 already strongly reduces the biological activity. The acyclic precursors containing thiol protection groups display weak biological activities. These results further underline the importance of the side chain in position 11 of substance P and suggest that optimal biological activities may require a linear peptide sequence.
