The SAR of 2-pyridyl-3,5-diaryl pyrroles, ligands of the human glucagon rec
eptor and inhibitors of p38 kinase, were investigated. This effort resulted
in the identification of 2-(4-pyridyl)-5-(4-chlorophenyl)-3-(5-bromo-2-pro
pyloxyphenyl)pyrrole 49 (L-168,049), a potent (Kb = 25 nM), selective antag
onist of glucagon. (C) 1999 Elsevier Science Ltd. All rights reserved.
