| Description | TGF-β1/Smad3-IN-1 (Compound 5aa) is an orally administrable dual inhibitor of TGF-β1/Smad3 with anti-fibrotic activity and can be used for the study of idiopathic pulmonary fibrosis (IPF). |
| In vitro | TGF-β1/Smad3-IN-1 (100-500 nM; 48 h) induced a decrease in TGF-β1 levels in H2228 cells [1]. TGF-β1/Smad3-IN-1 (2-6 μM; 24 h) dose-dependently inhibited p-Smad3 and α-SMA expression, significantly suppressing NIH3T3 cell migration[1]. TGF-β1/Smad3-IN-1 (3-10 μM; 72 h) increased Cleave-caspase3 expression in NIH3T3 cells and induced apoptosis in a dose-dependent manner [1]. |
| In vivo | TGF-β1/Smad3-IN-1 (p.o.; 100 mg/kg/day; days 2–20) treated a bleomycin-induced mouse model of pulmonary fibrosis, suppressing bleomycin-induced expression of pulmonary TGFβ1 and HYP, reducing extracellular matrix deposition, and alleviating pulmonary fibrosis [1]. |
