Primary Target
TGF-β1-dependent Smad3 phosphorylation and Smad3-mediated cellular signaling
The specific inhibitor of Smad3 (SIS3) is a pyrrolopyridine compound. It selectively blocks transforming growth factor (TGF)-β1-dependent mothers against decapentaplegic homolog 3 (Smad3) phosphorylation and Smad3-mediated cellular pathway without affecting Smad2, p38 mitogen-activated protein kinase (MAPK), extracellular-signal-regulated kinase (ERK), or phosphoinositide 3-kinase (PI3K) signaling. Through its inhibitory function, SIS3 regulates fibrosis, apoptosis, and inflammation in mouse unilateral ureteral obstruction (UUO) kidneys. Therefore, SIS3 can be an effective drug in further anti-fibrosis treatment of kidney disease.

Application

The specific inhibitor of Smad3 (SIS3) has been used to block transforming growth factor (TGF)-β/ mothers against decapentaplegic homolog 3 (SMAD3) signaling to characterize the signaling pathways that contribute to the activation of signal transducer and activator of transcription 3 (STAT3) in lung fibroblasts. It has also been used as a SMAD3 inhibitor in serum-free media to assess its ability to prevent the acrolein effect in ARPE-19 cells.Smad3 inhibitor has also been used in in scrape-loading dye-transfer assays to evaluate the functionality of gap junctions in chondrocytes.

General description

Smad3 inhibitor is a cell-permeable pyrrolopyridine compound that selectively inhibits TGF-β1-dependent Smad3 phosphorylation and Smad3-mediated cellular signaling with no effect on Smad2, p38 MAPK, ERK, or PI 3-K signaling.
