General description
一种细胞渗透性三芳基咪唑化合物，经证明可有效抑制NIH 3T3细胞中组成性活性ALK4、ALK5或ALK7的载体介导表达后的细胞Smad2磷酸化（10 µM抑制剂抑制>90%），而在表达活性ALK1、2、3或6的NIH 3T3培养物中，TGF-βⅠ型受体的其他成员对Smad1磷酸化几乎没有影响。当在无细胞激酶分析中直接测试时，SB431542被证明能有效抑制ALK4和ALK5的活性（IC50分别为140 nM和94 nM），而对包括ALK2和ALK6在内的24种其他激酶（IC50在10 µM ATP存在下为≥10 µM）没有效力或大大降低效力。据报道，当与PD0325901（目录号444966）和噻唑维文（目录号420220）一起使用时，4-TF诱导的成纤维细胞培养产生人类IPSC的效率提高了>200倍。

Following peripheral nerve injury, remnant Schwann cells adopt a migratory phenotype and remodel the extracellular matrix allowing axonal regrowth. Although much evidence has demonstrated that TGF-β1 promotes glioma cell motility and induces the expression of extracellular matrix proteins, the effects

During development, quiescent airway basal stem cells are derived from proliferative primordial progenitors through the cell-cycle slowdown. In contrast, basal cells contribute to adult tissue regeneration by shifting from slow cycling to proliferating and subsequently back to slow cycling. Although
