Smad3 Selective Inhibitors | Modulators

Catalog No. Product Name Information Selective / Pan IC50 / Ki
S7959 SIS3 HCl SIS3, a novel specific inhibitor of Smad3, inhibits TGF-β and activin signaling by suppressing Smad3 phosphorylation without affecting the MAPK/p38, ERK, or PI3-kinase signaling pathways. Selective
S8318 Alantolactone Alantolactone (helenin, helenine, Eupatal), a naturally occurring eudesmane-type sesquiterpene lactone (SL), could induce activin/SMAD3 signaling and disrupt Cripto-1/activin receptor type II A interaction. Selective
S8144 Halofuginone Halofuginone (RU-19110) is the competitively inhibitor of prolyl-tRNA synthetase with Ki of 18.3 nM.It could also down-regulate Smad3 and blocked TGF-β signaling at 10 ng/ml in mammal. Selective
S0752 AUDA AUDA (compound 43) is a potent inhibitor of soluble epoxide hydrolase (sEH) with IC50 of 18 nM and 69 nM for the mouse sEH and human sEH, respectively. AUDA has anti-inflammatory activity that reduces the protein expression of MMP-9, IL-1β, TNF-α and TGF-β. AUDA downregulates Smad3 and p38 signaling pathways. Pan
