Description:


IC50: 0.013 μM


Transforming growth factor-β (TGF-β) belongs to the TGF-β superfamily, which consists of TGF-β1, TGF-β2, TGF-β3. TGF-β and its receptors are often chronically overexpressed in various human diseases, such as cancer, tissue fibrosis, inflammation, and autoimmunity. Therefore, blockade of TGF-β signaling pathway is an attractive target for drug development. Following TGF-β binding to the constitutively active type II receptor, the type I receptor (ALK5) is phosphorylated and creates a binding site for Smad2/Smad3 proteins, which are further phosphorylated. EW-7197 is a highly potent, selective inhibitor of TGF-β type I receptor kinase.


In vitro: 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].


In vivo: 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].


Clinical trial: The First in human dose escalation study of EW-7197 in subjects with advanced stage solid tumors is ongoing [3].
