选择性Smad3抑制剂。SIS3 free base 是一种有效和选择性的 TGF-β1 诱导的 Smad3 磷酸化抑制剂,IC50 为 3 μM。SIS3 free base 通过消除 ALK-5 组成型活性形式的过表达来提高 p3TP-lux 的荧光素酶活性。
生物活性
SIS3 free base is a potent and selective inhibitor of Smad3 phosphorylation. SIS3 free base inhibits the myofibroblast differentiation of fibroblasts by TGF-β1. SIS3 free base does not affect the phosphorylation of Smad2.
