Abstact

The 4-(5-fluoro-6-methyl-pyridin-2-yl)-5-quinoxalin-6-yl-1H-imidazol-2-ylamine 3 is a potent and selective inhibitor of TGF-betaR1. Substitution of the amino group of 3 typically led to a slight decrease in the affinity for the receptor and in TGF-beta-inducted PAI-luciferase reporter activity. However, 2-acetamidoimidazoles were identified as attractive candidates for further optimization as a result of their significant activity combined to their superior pharmacokinetic profile.
