SIS3 free base is a potent and selective inhibitor of Smad3 phosphorylation. SIS3 free base inhibits the myofibroblast differentiation of fibroblasts by TGF-β1 . SIS3 free base does not affect the phosphorylation of Smad2
In Vitro
SIS3 free base attenuates the TGF-beta1-induced phosphorylation of Smad3 and interaction of Smad3 with Smad4. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Western Blot AnalysisCell Line: Human dermal fibroblasts Concentration: 0.3, 1, 3, 10 μM Incubation Time: For 1 hour Result: Attenuated the TGF-beta1-induced phosphorylation of Smad3 and interaction of Smad3 with Smad4.
