应用

Smad3(SIS3)的特异性抑制剂已被用于阻断转化生长因子(TGF)-β/母体十肽同系物3 (SMAD3)信号转导,以表征肺成纤维细胞中有助于信号转导子和转录激活子3(STAT3)活化的信号转导途径 。它也可用作无血清培养基中的SMAD3 抑制剂,用于评估其预防ARPE-19细胞中丙烯醛作用的能力。

生化/生理作用

Smad3(SIS3)的特异性抑制剂是一种吡咯并吡啶化合物。它选择性阻断转化生长因子(TGF)-β1-依赖型母体十肽同系物3 (Smad3) 磷酸化和Smad3介导的细胞途径,但是不影响Smad2, p38分裂素活化的蛋白质激酶(MAPK)、胞外信号调节激酶(ERK)或磷酸肌醇3-激酶(PI3K)信号传导。 通过其抑制功能, SIS3调节小鼠单侧输尿管梗阻(UUO)肾的纤维化、细胞凋亡和炎症。因此,SIS3可用作肾病抗纤维化治疗的有效药物。
主要靶标
TGF-β1依赖性Smad3磷酸化和Smad3介导的细胞信号转导
