TG101209是JAK2选择性抑制剂,IC50为6 nM,对Flt3和RET的IC50为25 nM和17 nM,比对JAK3的抑制性高30倍,对JAK2V617F和MPLW515L/K突变型敏感,还能抑制BRD4,IC50为130 nM。
TG101209 is a selective JAK2 inhibitor with IC50 of 6 nM, less potent to Flt3 and RET with IC50 of 25 nM and 17 nM in cell-free assays, ~30-fold selective for JAK2 than JAK3, sensitive to JAK2V617F and MPLW515L/K mutations.
4.6-38 400 nM
100 mg/kgTG101209 以指示剂量口服强饲给药,在肿瘤细胞输注3天后开始给药,20天后停止。
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。
