SB431542是一种有效的,选择性的ALK5抑制剂,IC50为94 nM,对ALK5的作用比对p38,MAPK和其他激酶强100倍。
SB 431542 is a small molecule that acts as a specific and selective inhibitor of TGFβ RI, ACTR-IB and ACTR-IC (transforming growth factor-β superfamily type I activin receptor-like kinase (ALK) receptors ALK4, 5, and 7). Renal carcinoma studies have demonstrated that SB 431542 is a selective inhibitor of Smad3 phosphorylation (IC50= 94nM) and TGF-β-1 collagen induced lα1 (col Iα1). Potent and selective inhibitor of the transforming growth factor-β (TGF-β) type I receptor activin receptor-like kinase ALK5 (IC50 = 94 nM), and its relatives ALK4 and ALK7.

动物 A (mg/kg) = 动物 B (mg/kg)×动物 B的Km系数/动物 A的Km系数 | |
例如,已知某工具药用于小鼠的剂量为88 mg/kg , 则用于大鼠的剂量换算方法:将88 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到该药物用于大鼠的等效剂量44 mg/kg。
