Abstract

A series of pseudopeptide analogues of the C-terminal heptapeptide of cholecystokinin in which each peptide bond, one at a time, has been replaced by a CH2NH bond were synthesized: Z-Tyr (S03-)-Nle-Gly-Trp-Nle-Asp $-(CHzNH) P he-NH2 (1 1, Z-Tyr (SO,-)-Nle- Gly-Trp-Nle $(CH2NH) Asp-Phe-NH2 (2), Z-Tyr (SO,-)-Nle-Gly-Trp $-
