General description

A-83-01 may effectively prevent burn wound contraction without impeding wound closure, due to its ability to inhibit the transforming growth factor-β (TGF-β)-induced rise in myofibroblast population. Additionally, it can hinder TGF-β1-dependent cancer metastasis by suppressing epithelial-mesenchymal transition (EMT) in animals.

Application

A 83-01 has been used as an inhibitor of transforming growth factor β kinase type 1 receptor.
A 83-01 has been used:
  • in the culture medium for organoid formation from dissociated tumor cells,
  • as a component in Dulbecco′s modified Eagle medium/nutrient mixture F-12 (DMEM/F12) for culturing human epidermal stem cells (EpSCs)

Biochem/physiol Actions

A 83-01 is a TGFβ kinase/activin receptor-like kinase (ALK 5) inhibitor (IC50=12 nM) that prevents phosphorylation of Smad2/3 and inhibits growth induced by TGFβ. A 83-01 blocks phosphorylation of Smad2 and inhibits TGF-β-induced epithelial-to-mesenchymal transition. Also, A 83-01 inhibits the transcriptional activity induced by TGFβ type I receptor ALK-5, activin type IB receptor ALK-4 and nodal type I receptor ALK-7. A-83-01 induces an expansion of neonatal Nkx2.5-eGFP (+) cells.
