Application

SB-505124 hydrochloride hydrate was used to study the role of TGF-β pathway in development and differentiation studies.3,4

Biochem/physiol Actions

SB-505124 is an inhibitor of activin receptor-like kinase (ALK) 5, also known as transforming growth factor-α type I receptor kinase, with an IC50 of 47 ± 5 nM.
SB-505124 selectively inhibits TGF-β type I receptors, activin receptor-like kinases (ALK) 4, 5 and 7. It inhibits ALK4-, 5- and 7-mediated activation of Smad2, Smad3 and MAPK pathway induced by TGF-β.1 SB-505124 inhibits the human fibroblast trans-differentiation induced by the co-culture with Esophageal squamous cell carcinoma.2
