Abstract: A series of 2-(6-methylpyridin-2-yl)-1H-imidazoles were synthesized and evaluated for ALK5 inhibitory activity in cell-based luciferase reporter assays. The compound 4-(((1-(benzo[d][1,3]dioxol-5-yl)-2-(6-methylpyridin-2-yl)-1H-imidazol-4-yl)methyl)amino)benzenesulfonamide (27a) exhibited slightly higher inhibition (IC50=0.24μM) than SB431542 (IC50=0.35μM), a well known potent ALK5 inhibitor. The binding mode of 27a generated by flexible docking study shows that it fits well into the site cavity of ALK5 by forming several tight interactions.
