A novel Pd-catalyzed cyclization reaction of ureas for the synthesis of dihydroquinazolinone p38 kinase inhibitors
摘要:
A series of potent p38 inhibitors based on the dihydroquinazoline scaffold was synthesized using a novel Pd-catalyzed cyclization reaction of aryl-benzyl ureas. Optimization of this compound class led to compound 20, which inhibits p38alpha in vitro with IC50 = 14 nM and is active in the mouse TNFalpha-release model. (C) 2003 Elsevier Ltd.
