Mechanism of Action

Targets/IC₅₀/Ki	ALK5 (Cell-free assay) 11 nM ALK4 (Cell-free assay) 13 nM
In vitro	In HaCaT (3TP-luc) and 4T1 (3TP-luc) stable cells, 12b potently inhibits the TGF-β1-induced luciferase reporter activity with IC50 of 16.5 and 12.1 nM, respectively. EW-7197 inhibits TGFβ-induced Smad2 or Smad3 phosphorylation and the epithelial-to-mesenchymal transition (EMT) in TGFβ-treated breast cancer cells. In addition, EW-7197 also abrogates TGFβ1-induced tumor cell migration and invasion in breast cells.
Kinase Assay	Protein Kinase Assay
Kinase Assay	A radioisotopic protein kinase assay (HotSpot assay) is performed at Reaction Biology Corporation.
In vivo	In rats, EW-7197 shows an oral bioavailability of 51% with high systemic exposure (AUC) of 1426 ng×h/mL and maximum plasma concentration (Cmax) of 1620 ng/mL. EW-7197 also shows low toxicity on the cardiovascular system, central nervous system, and respiratory system. [1] In a mouse B16 melanoma model, EW-7197 (2.5 mg/kg daily p.o.) suppresses the progression of melanoma with enhanced cytotoxic T-lymphocyte (CTL) responses. EW-7197 enhances cytotoxic T lymphocyte activity in 4T1 orthotopic-grafted mice and increased the survival time of 4T1-Luc and 4T1 breast tumor-bearing mice.
