Vactosertib (EW-7197) 是一种有效的，具有口服活性且具有 ATP 竞争性激活素受体样激酶 5 (ALK5) 抑制剂，IC₅₀ 为 12.9 nM。Vactosertib 还以纳摩尔浓度抑制 ALK2 和 ALK4 (IC₅₀ 为 17.3 nM)。Vactosertib 具有强大的抗转移活性和抗癌作用。

Vactosertib (EW-7197) is a potent, orally active and ATP-competitive activin receptor-like kinase 5 (ALK5) inhibitor with an IC 50 of 12.9 nM. Vactosertib also inhibits ALK2 and ALK4 (IC 50 of 17.3 nM) at nanomolar concentrations. Vactosertib has potently antimetastatic activity and anticancer effect.

ALK5 12.9 nM (IC50)

Vactosertib (10-1000 nM; 30 minutes; 4T1 cells) treatment blocks the TGFβ-induced phosphorylation of Smad2 or Smad3 in a dose-dependent manner in 4T1 cells.
Vactosertib suppresses the TGFβ-induced nuclear translocation of Smad2/3 in 4T1 cells and MCF10A cells. The IC50 value of Vactosertib on pSmad3 in 4T1 cells is 10-30 nM.
Vactosertib abrogates TGFb1-induced tumor cell migration and invasion.
TGFβ1 downregulated the mRNA level of CDH1 and upregulated the mRNA levels of FN1, HMGA2 (high-mobility group AT-hook 2), SNAI1, and SNAI2 (Snail family zinc finger 1 and 2, respectively). Moreover, Vactosertib abolishes the TGFβ1-induced effects on genes related to epithelial-to-mesenchymal transition (EMT). has not independently confirmed the accuracy of these methods. They are for reference only.

Vactosertib (40 mg/kg; intraperitoneal injection; every other day; for 10 weeks; MMTV/c-Neu female mice) treatment inhibits Smad/TGFβ signaling, cell migration, invasion, and lung metastasis in MMTV/c-Neu mice.
Vactosertib also inhibits the epithelial-to-mesenchymal transition (EMT) in both TGFβ-treated breast cancer cells and 4T1 orthotopic-grafted mice. Furthermore, Vactosertib enhances cytotoxic T lymphocyte activity in 4T1 orthotopic-grafted mice and increased the survival time of 4T1-Luc and 4T1 breast tumor-bearing mice. has not independently confirmed the accuracy of these methods. They are for reference only.
