Modification of Receptor Selectivity and Functional Activity in Cholecystokinin Peptoid Ligands

Hybrid analogs of the cholecystokinin A (CCK-A) receptor selective tetrapeptide agonist Boc-Trp-Lys(Tac)-Asp-MePhe-NH2 (1, A-71623) and the CCK-B receptor selective antagonists PD-135118 (2) and CI-988 (3) were prepared.Incorporation of the Lys(Tac) side
