EW-7197 is a highly potent, selective, and orally bioavailable TGF-β I receptor ALK4/ALK5 inhibitor.

ew-7197 inhibited alk5 with ic50 value of 0.013 μm in a kinase assay and with ic50 values of 0.0165 and 0.0121 μm in hacat stable cells and 4t1 stable cells, respectively, in a luciferase assay. selectivity profiling of ew-7197 using a panel of protein kinases revealed that it is a highly selective alk5/alk4 inhibitor [1].

ew-7197 inhibited smad/tgf-βsignaling, invasion, cell migration, and lung metastasis in mmtv/c-neu mice and 4t1 orthotopic–grafted mice. ew-7197 inhibited the epithelial-to-mesenchymal transition in both tgf-β-treated breast cancer cells and 4t1 orthotopic–grafted mice as well[2].
