  C-terminal anthranoyl–anthranilic acid derivatives and their evaluation on CCK receptors

  摘要：

  A series of C-terminal anthranoyl-anthranilic acid derivatives arising from a strict bond disconnection approach of asperlicin were synthesized and examined for their CCK receptor affinities. These compounds represent the second step of our investigation directed toward the search for alternative substructures of asperlicin as a starting point for the development of a new class of CCK ligands. The obtained micromolar affinities for CCK-A rather than CCK-B receptor confirm that the anthranilic acid dimer represents a useful template for the development of selective CCK-A receptor ligands.

  Anthranilic acid based CCK1 receptor antagonists: Blocking the receptor with the same ‘words’ of the endogenous ligand

  摘要：

  The anthranilic acid diamides represent the more recent class of nonpeptide CCK1 receptor antagonists. This class is characterized by the presence of anthranilic acid, used as a molecular scaffold, and two pharmacophores selected from the C-terminal tetrapeptide of CCK. The lead compound coded VL-0395, endowed with sub-micromolar affinity towards CCK1 receptors, was characterized by the presence of Phe and 2-indole moiety at the C- and N-termini of anthranilic acid, respectively. Herein we describe the first step of the anthranilic acid C- terminal optimization using, instead of Phe, aminoacids belonging to the primary structure of CCK-8 and other not coded residues. Thus we demonstrate that the CCK1 receptor affinity depends on the nature of the aminoacidic side chain as well as that the free carboxy group of the alpha-aminoacids is crucial for the binding. The R enantiomers of the most active compounds represent the eutomers of this class of antagonists confirming thus the stereo preference of the receptor. Moreover this SAR study demonstrates that the receptor binding pocket, that host the aminoacidic side chain, results much more tolerant respect to that accommodating the indole ring. As a result, an appropriate variation of the aminoacidic side chain could provide a better CCK1 receptor affinity diorthosis. (C) 2009 Elsevier Ltd. All rights reserved.

  Transition‐metal‐free synthesis of α‐aryl esters and nitriles using arylboronic acids with α‐aminoesters and α‐aminoacetonitriles, respectively, as the starting materials has been developed. The reaction represents a rare case of converting C(sp3)N bonds into C(sp3)C(sp2) bonds. The reaction conditions are mild, demonstrate good functional‐group tolerance, and can be scaled up.
