[Synthesis of cyclic and non-cyclic tachykinin partial sequences. 2. Synthesis of the homocyclic substance P(6-11) hexapeptide].
The authors describe the synthesis of Gln-Phe-Phe-Gly-Leu-Met by cyclization of H-Leu-Met-Gln-Phe-Phe-Gly using three different methods. The linear sequence was obtained by a (2+4)-segment condensation. The resulting cyclopeptide showed only a small kinin activity on isolated guinea pig ileum compared to substance P, but it is a full agonist.
