A series of 2-benzylamino-4(5)-(6-methylpyridin-2-yl)-5(4)-([1,2,4]triazolo[1,5-a]pyridin-6-yl)thiazoles 12a-ab, 13a, 13b, and 18a-d has been synthesized and evaluated for their ALK5 inhibitory activity in an enzyme assay and in a cell-based luciferase reporter assay. The N-(3-fluorobenzyl)-4-(6-methylpyridin-2-yl)-5-([1,2,4]triazolo[1,5-a]pyridin-6-yl)thiazol-2-amine (12b) inhibited ALK5 phosphorylation with an IC50 value of 7.01 nM and showed 61% inhibition at 30 nM in a luciferase reporter assay using HaCaT cells permanently transfected with p3TP-luc reporter construct.
