EW-7197 Chemical Properties,Usage,Production

Description

EW-7197 is a potent inhibitor of activin receptor-like kinase 5 (ALK5, also known as TGF-β receptor type 1; IC₅₀ = 12.9 nM). It also inhibits ALK2 and ALK4 at nanomolar concentrations. EW-7197 blocks TGF-β/Smad signaling, cell migration, invasion, and lung metastasis in mouse mammary tumor virus/c-Neu mice and 4TI orthotopic-grafted mice. It also inhibits epithelial-to-mesenchymal transition (EMT) in TGF-β-treated breast cancer cells. EW-7197 is used to block TGF-β signaling and EMT in animal models of cancer and fibrosis.

Description

EW-7197 is a novel ALK-5 kinase inhibitor as well as TGF-β Type I Receptor Kinase Inhibitor. Study has shown that it can potently inhibit the breast to lung metastasis. Mice study has demonstrated that EW-7197 inhibited Smad/TGFβ signaling, cell migration, invasion, and lung metastasis in MMTV/c-Neu mice and 4T1 orthotopic-grafted mice. EW-7197 also inhibited the epithelial-to-mesenchymal transition (EMT) in both TGFβ-treated breast cancer cells and 4T1 orthotopic-grafted mice. Furthermore, EW-7197 enhanced cytotoxic T lymphocyte activity in 4T1 orthotopic-grafted mice and increased the survival time of 4T1-Luc and 4T1 breast tumor-bearing mice. It can also inhibit hepatic, renal, and pulmonary fibrosis by blocking TGF-β/Smad and ROS signaling. Therefore, it is a potential antitumor reagent.

Uses

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

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].
