  study, we have investigated the effects of replacement of the D-Tic-Oic moiety by various constrained dipeptide mimetics. The resulting compounds were tested for their binding affinity toward the cloned human B(2) receptor and for their functional interaction with the bradykinin-induced contraction of isolated human umbilical vein. Subsequently, we have designed novel bradykinin B(2) receptor agonists

  A series of modifications of the CCK7 analogue (des-NH2)Tyr(SO3-)-Nle-Gly-Trp-Nle-Asp-Phe-NH2 was prepared and tested for binding to guinea pig CCK-A and CCK-B receptors and in CCK-A-mediated functional assays. Selected analogues also were tested for appetite suppressant activity in rats. Several conformationally restricted residues in the C-terminal tetrapeptide region, including DELTA(Z)-Phe33, (N-Me)Phe33, (N-Me)Asp32, (N-Me)Leu31, and 3PP31 (3PP = trans-3-n-propyl-L-proline) were found to be acceptable modifications at one or both receptor subtypes. The (N-Me)Asp32 and (N-Me)Leu31 modifications afforded potent and selective CCK-A and CCK-B ligands, respectively. SAR studies in the N-terminal acyldipeptide region examined structural requirements for the side chain at position 28, where Gly and Pro replacements were found to possess high affinity at both receptor subtypes. Other conformationally restrictive modifications were less active. All of the analogues that showed high affinity (<10 nM) for the CCK-A receptor also were full agonists in amylase release and most were full or nearly full agonists in the phosphoinositide (PI) turnover assay, the most notable exception being the DELTA(Z)-Phe33 analogue, which showed 69% of the maximal response in the PI assay. Potent activity in suppression of food intake in rats was found for selected analogues.
• Design and Synthesis of Photoaffinity-Labeling Ligands of the <scp>l</scp>-Prolyl-<scp>l</scp>-leucylglycinamide Binding Site Involved in the Allosteric Modulation of the Dopamine Receptor

  Pro-Leu-Gly-NH2 (PLG), in addition to its endocrine effects, possesses the ability to modulate dopamine D-2 receptors within the central nervous system. However, the precise binding site of PLG is unknown. Potential photoaffinity-labeling ligands of the PLG binding site were designed as tools to be used in the identification of the macromolecule that possesses this binding site. Six different photoaffinity-labeling ligands were designed and synthesized on the basis of the gamma-lactam PLG peptidomimetic 1. The 4-azidobenzoyl and 4-azido-2-hydroxybenzoyl photoaffinity-labeling moieties were placed at opposite ends of PLG peptidomimetic I to generate a series of ligands that potentially could be used to map the PLG binding site. All of the compounds that were synthesized possessed activity comparable to or better than PLG in enhancing [H-3]-N-propylnorapomorphine agonist binding to dopamine receptors. Photoaffinity ligands that were crosslinked to the receptor preparation produced a modulatory effect that was either comparable to or greater than the increase in agonist binding produced by the respective ligands that were not cross-linked to the dopamine receptor. The results indicate that these photoaffinity-labeling agents are binding at the same allosteric site as PLG and PLG peptidomimetic 1.

  Leu-Gly-NH2 dipeptide segment of PLG was replaced with the gamma-lactam residues 3(S)- and 3(R)-amino-2-oxopyrrolidineacetamide and the delta-lactam residue 3(S)-amino-2-oxopiperidineacetamide. The corresponding gamma-lactam analogues of less than Glu-Leu-Gly-NH2 were also synthesized. In a second series of analogues, the glycinamide residue of PLG was replaced with the 2-ketopiperazine, 3(S)-amino-2-pyrrolidone
