A series of 5-(pyridin-2-yl)thiazoles (14a-l and 15a-l) has been synthesized and evaluated for their ALK5 inhibitory activity in cell-based luciferase reporter assays. Among them, 3-[[5-(6-methylpyridin-2-yl)-4-(quinoxalin-6-yl)thiazol-2-ylamino]methyl]benzamid e (15i) and 3-[[5-(6-ethylpyridin-2-yl)-4-(quinoxalin-6-yl)thiazol-2-ylamino]methyl]benzamide (15k) showed more than 95% inhibition at 0.1

has been synthesised and evaluated for their ALK5 inhibitory activity in an enzyme assay and in a cell-based luciferase reporter assay. Incorporation of a quinoxalin-6-yl moiety and a methylene linker at the 4- and 2-position of the imidazole ring, respectively, and a m-CONH2 substituent in the phenyl ring generated a highly potent and selective ALK5 inhibitor 11e.
