Definitions

• the present invention relates to agents that act to antagonize the action of the giucagon peptide hormone. It relates particularly to non-peptide giucagon antagonists or inverse agonists.
• giucagon can be suppressed by providing an antagonist or an inverse agonist, substances that inhibit or prevent giucagon induced response.
• the antagonist can be peptide or non-peptide in nature.
• Native giucagon is a 29 amino acid- containing peptide having the sequence: His-Ser-Glu-Gly-Thr-Phe-Thr-Ser-Asp-Tyr-Ser-Lys-Tyr-Leu-Asp-Ser-Arg-Arg-Ala-Gln-Asp- Phe-Val-Gln-Trp-Leu-Met-Asn-Thr-NH 2 .
• Giucagon exerts its action by binding to and activating its receptor, which is part of the Glu- cagon-Secretin branch of the 7-transmembrane G-protein coupled receptor family (Jelinek et al. Science 259, 1614, (1993)).
• the receptor functions by activation of the adenylyl cyclase second messenger system and the result is an increase in cA P levels.
• WO 94/14426 discloses use of skyrin, a natural product comprising a pair of linked 9,10-anthracenedione groups, and its synthetic analogues, as giucagon antagonists.
• Anderson, P.L., U.S. Patent No. 4,359,474 discloses the giucagon antagonistic properties of 1- phenyl pyrazole derivatives.
• Barcza, S., U.S. Patent No. 4,374,130 discloses substituted disi- lacyclohexanes as giucagon antagonists.
• WO 98/04528 (Bayer Corporation) discloses substituted pyridines and biphenyls as giucagon antagonists.
• WO 97/16442 discloses substituted pyridyl pyrroles as giucagon antagonists
• WO 98/21957 discloses 2,4-diaryl-5-pyridylimidazoles as giucagon antagonists. These giucagon antagonists differ structurally from the present compounds. Description of the invention
