title: Synthesis and biological evaluation of novel 2-pyridinyl-[1,2,3]triazoles as inhibitors of transforming growth factor beta 1 type 1 receptor.
abstract: A series of 2-pyridinyl-[1,2,3]triazoles have been synthesized and evaluated for their ALK5 inhibitory activity in the luciferase reporter assays. Compound 8d showed significant ALK5 inhibition (SBE-luciferase activity, 25%; p3TP-luciferase activity, 17%) at a concentration of 5 microM that is comparable to that of SB-431542 (SBE-luciferase activity, 21%; p3TP-luciferase activity, 12%), but weak p38 alpha MAP kinase inhibition (13%) at a concentration of 10 microM that is much lower than that of SB-431542 (54%).
