PRT062607 (P505-15, BIIB057) HCl是一种新型,高度选择性的Syk抑制剂,IC50为1 nM,作用于Syk比作用于Fgr, Lyn, FAK, Pyk2和Zap70选择性高80倍以上。
PRT062607 (P505-15, BIIB057) HCl is a novel, highly selective Syk inhibitor with IC50 of 1 nM in cell-free assays, >80-fold selective for Syk than Fgr, Lyn, FAK, Pyk2 and Zap70.
~6 μM
5, 15, 30 mg/kg, 每天两次口服处理
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。
