Abstract

A series of 1-substituted-3(5)-(6-methylpyridin-2-yl)-4-(quinoxalin-6-yl) pyrazoles 14a-d, 15a-d, 17a, 17b, 18a-d, 19a, and 19b has been synthesized and evaluated for their ALK5 inhibitory activity in an enzyme assay and in a cell-based luciferase reporter assay. The 2-[3-(6-methylpyridin-2-yl)-4- (quinoxalin-6-yl)-1H-pyrazol-1-yl]-N-phenylethanethioamide (18a) inhibited ALK5 phosphorylation with an IC ₅₀ value of 0.013 μM and showed 80% inhibition at 0.1 μM in a luciferase reporter assay using HaCaT cells permanently transfected with p3TP-luc reporter construct.
