  A New Class of Nonpeptide Bradykinin B₂ Receptor Ligand, Incorporating a 4-Aminoquinoline Framework. Identification of a Key Pharmacophore To Determine Species Difference and Agonist/Antagonist Profile

  摘要：

  Introduction of various aliphatic amino groups at the 4-position of the quinoline moiety of our nonpeptide bradykinin (BK) B-2 receptor antagonists afforded highly potent ligands for human B-2 receptor with various affinities for guinea pig B-2 receptor, indicating remarkable species difference. A representative 4-dimethyamino derivative 40a exhibited subnanomolar and nanomolar binding affinities for human and guinea pig B-2 receptors, respectively, and significantly inhibited BK-induced bronchoconstriction in guinea pigs at 10 mug/kg by intravenous administration. Further chemical modification led us to discover unique partial agonists for the human B-2 receptor that increase inositol phosphates (IPs) production by themselves in Chinese hamster ovary (CHO) cells expressing the cloned human B-2 receptor. Although their potency and efficacy were much lower than those of BK, we identified them as screening leads for nonpeptide B-2 agonists. In these studies it was revealed the 4-substituent of the quinoline moiety is the key pharmacophore to determine species difference and agonist/antagonist profiles.
