[Substance P. New cyclic analogs].
[Adpoc-Glu(N3)6, (Met-N3)11] substance P-(6-11)-peptide was reacted with diamines H2N(CH2) nNH2 (n = 3-10, 12) to give cyclopeptides. Subsequent careful cleavage of the Adpoc group leads to the formation of compounds of type cyclo-[H-Glu-Phe-Phe-Gly-Leu-Met-NH-(CH2) n-NH-] X HCl. The substances produce a specific two-phase myotropic effect in experiments on isolated guinea pig ileum. The compounds where n is 3, 7, 12 exhibit also a hypotensive activity when assayed on anaesthetized rats.
