Biological Activity

Description Vactosertib  (TEW-7197, EW-7197) is a highly potent, selective, and orally bioavailable TGF-β receptor ALK4/ALK5 inhibitor with IC50 of 13 nM and 11 nM, respectively. Phase 1.
Targets
ALK5 [1]
(Cell-free assay)		 ALK4 [1]
(Cell-free assay)
11 nM 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. [1] 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. [3]
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. [2] 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. [3]

Protocol (from reference)

Kinase Assay:

[1]
  • Protein Kinase Assay

    A radioisotopic protein kinase assay (HotSpot assay) is performed at Reaction Biology Corporation.

Cell Assay:

[3]
  • Cell lines

    4T1 and MCF10A cells

  • Concentrations

    ~5 μM

  • Incubation Time

    72 hours

  • Method

    Cells are seeded in 96 well plate and treated with indicated concentrations of EW-7197 in 0.2% HI-FBS medium for 72 h. Cells are dried after incubation with 10% TCA in media. Then, cells are incubated with 0.4% SRB (Sulforhodamine B) in 1% acetic acid for 30 min. After washing with 1% glacial acetic acid, bounded dye is released in 10 mM Tris buffer (pH 10.5) for 30 min. Absorbance is measured at 570 nm.
Animal Study:

[2]
  • Animal Models

    Mouse B16 melanoma model

  • Dosages

    2.5 mg/kg daily

  • Administration

    p.o.
