How to use

In Vitro:

SM16 inhibits TGFβ-induced plasminogen activator inhibitor-luciferase activity (IC50=64 nM) and TGFβ- or activin-induced Smad2 phosphorylation at concentrations between 100 and 620 nM. SM16 is tested against >60 related and unrelated kinases and shows moderate off-target activity only against Raf (IC50=1 μM) and p38/SAPKa (IC50=0.8 μM). SM16 exhibits no inhibitory activity against ALK family members ALK1 and ALK6.

In Vivo:

SM16 penetrates tumor cells in vivo, suppressing tumor phosphorylated Smad2/3 levels for at least 3 h following treatment of tumor-bearing mice with a single i.p. bolus of 20 mg/kg SM16. The growth of established AB12 tumors is significantly inhibited by 5 mg/kg/d SM16 (P<0.001) delivered via s.c. miniosmotic pumps over 28 days.
