How to use

In Vitro:

SIS3 HCl (0.3-10 μM; for 1 hour) attenuates the TGF-beta1-induced phosphorylation of Smad3 and interaction of Smad3 with Smad4. SIS3 HCl (0.1 , 10, 50 μM; 30 min) significantly suppresses the expression of FN and α-SMA, but not that of Sphk2 provoked by TGF-β1. SIS3 HCl (10 μM; 24 hours) significantly reduces both α-SMA and palladin expression that is enhanced by TWEAK in Primary human dermal fibroblasts. SIS3 HCl significantly inhibits L4 development at five concentrations from as low as 2 µM to 50 µM (5 µM, 10 µM, 20 µM and 50 µM) in a dose-dependent manner.
