  Conformationally Constrained CCK4 Analogues Incorporating IBTM and BTD β-Turn Mimetics

  摘要：

  To test whether a turnlike arrangement is involved in the bioactive conformation of CCK4 analogues upon CCK1 receptor recognition, we describe the preparation of two series of CCK4 derivatives, in which the central dipeptide Met-Asp has been replaced by recognized beta-turn mimetics (2S,5S,11bR)- and (2R,5R,11bS)-2-amino-5-carboxy-3-oxo-2,3,5,6,11,11b-hexahydro-1H-indolizino[8,7-b]indole (IBTM) and beta-turn dipeptide, 2-oxo-7-thio-1-azabicyclo[4.3.0]nonane (BTD)}. The incorporation of the indolizinoindole IBTM type II beta-turn mimetic is preferred over its type II' counterpart for efficient CCK1 receptor recognition, while BTD derivatives were completely inactive. The structure-conformation-activity relationship study in the IBTM series has shown some essential requirement of these CCK4 derivatives to favorably interact with CCK1 receptors: (a) the adoption of turnlike conformations, (b) the presence of an 1-Phe residue and a C-terminal carboxamide moiety, and (c) the indole ring of the IBTM skeleton. Moreover, the existence of pi-pi interactions between the phenyl ring of D-Phe residues and the indole ring of IBTM framework is detrimental for binding affinity. A series of potent and selective CCK1 receptor antagonists, exemplified by compounds 8a and 8b, emerges among these IBTM-containing derivatives.

  approximately 6-fold higher CCK(1) selectivity than analogue 16a, with the type II mimetic. From these results, we propose that the presence of a beta-turn-like conformation within the peptide backbone of dipeptoids could contribute to their bioactive conformation at the CCK(1) receptor subtype. Concerning functional activity, compounds 15a and 16a behave as CCK(1) receptor antagonists.
