Optimized substituent patterns in 4-aryl-pyridine glucagon receptor antagonists were merged to produce highly potent derivatives containing both a 3-[(1R)-hydroxyethyl] and a 2′-hydroxy group. Due to restricted rotation of the phenyl-pyridine bond, these analogues exist as four isomers. A diastereoselective methylcopper reaction was developed to facilitate the synthesis, and single isomers were isolated with activities in the range IC50=10-25 nM.

A narrow structure-activity relationship was established for the 4-aryl group in 4-aryl-pyridine glucagon antagonists, with only small substituents being well-tolerated, and only at the 3′- and 4′-positions. However, substitution with a 2′-hydroxy group gave a ca. 3-fold increase in activity (e.g., 4′-fluoro-2′-hydroxy analogue 33, IC50=190 nM). For efficient preparation of 2′-substituted phenylpyridines, a novel synthesis via pyrones and 4-methoxy-pyridines was developed.
