Cell lines | HaCaT (3TP-luc) and 4T1 (3TP-luc) stable cells, TGFβ-treated breast cancer cells |
Preparation method | Soluble in DMSO. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
Reacting condition | 96 hours |
Applications | In HaCaT (3TP-luc) and 4T1 (3TP-luc) stable cells, EW-7197 potently inhibited the TGF-β1-induced luciferase reporter activity with IC50 of 16.5 and 12.1 nM, respectively. EW-7197 inhibited TGFβ-induced Smad2 or Smad3 phosphorylation and the epithelial-to-mesenchymal transition (EMT) in TGFβ-treated breast cancer cells. EW-7197 abrogated TGFβ1-induced tumor cell migration and invasion in breast cells. |
Animal models | Mouse mammary tumor virus (MMTV)/c-Neu mice and 4T1 orthotopic–grafted mice |
Dosage form | intraperitoneal injection, 40 mg/kg, three times per week for 10 weeks |
Application | EW-7197 inhibited Smad/TGFβ signaling, cell migration, invasion, and lung metastasis in MMTV/c-Neu mice and 4T1 orthotopic–grafted mice. EW-7197 inhibited the epithelial-to-mesenchymal transition (EMT) in 4T1 orthotopic–grafted mice. 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. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
| 产品描述 | 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]. Reference: |
