  Discovery of N-((4-([1,2,4]Triazolo[1,5-a]pyridin-6-yl)-5-(6-methylpyridin-2-yl)-1H-imidazol-2-yl)methyl)-2-fluoroaniline (EW-7197): A Highly Potent, Selective, and Orally Bioavailable Inhibitor of TGF-β Type I Receptor Kinase as Cancer Immunotherapeutic/Antifibrotic Agent

  摘要：

  A series of 2-substituted-4-([1,2,4]triazolo[1,5-a]pyridin-6-yl)-5-(6-methylpyriclin-2-yl)imidazoles was synthesized and evaluated to optimize a prototype inhibitor of TGF-beta type I receptor kinase (ALK5), 6. Combination of replacement of a quinoxalin-6-yl moiety of 6 with a [1,2,4]triazolo[1,5-a]pyridin-6-yl moiety, insertion of a methyleneamino linker, and a o-F substituent in the phenyl ring markedly increased ALK5 inhibitory activity, kinase selectivity, and oral bioavailability. The 12b (EW-7197) inhibited ALKS with IC50 value of 0.013 mu M in a kinase assay and with IC50 values of 0.0165 and 0.0121 mu M in HaCaT (3TP-luc) stable cells and 4T1 (3TP-luc) stable cells, respectively, in a luciferase assay. Selectivity profiling of 12b using a panel of 320 protein kinases revealed that it is a highly selective ALKS/ALK4 inhibitor. Pharmacokinetic study with 12b center dot HCl in rats showed an oral bioavailability of 51% with high systemic exposure (AUC) of 1426 ng x h/mL and maximum plasma concentration (C-max) of 1620 ng/mL. Rational optimization of 6 has led to the identification of a highly potent, selective, and orally bioavailable ALK5 inhibitor 12b.

  A series of 4-([1,2,4]triazolo[1,5-a]pyridin-6-yl)-5(3)-(6-methylpyridin-2-yl)imidazoles and -pyrazoles 14a-c, 15a-c, 16a, 16b, 19a-d, 21a, and 21b has been synthesized and evaluated for their ALK5 inhibitory activity in an enzyme assay and in a cell-based luciferase reporter assay. Among them, the pyrazole derivative 21b inhibited ALK5 phosphorylation with an IC50 value of 0.018 mu M and showed 95% inhibition at 0.03 mu M in a luciferase reporter assay using HaCaT cells permanently transfected with p3TP-luc reporter construct. The 21b showed a high selectivity index of 284 against p38 alpha MAP kinase. The binding pose of 21b generated by docking analysis reveals that it fits well into the ATP binding cavity of ALK5 by forming several hydrogen bond interactions. (C) 2014 Elsevier Ltd.
