  • 生物活性

    R788 (Fostamatinib) disodium, a prodrug of the active metabolite R406, is a Syk inhibitor with IC50 of 41 nM in a cell-free assay, strongly inhibits Syk but not Lyn, 5-fold less potent to Flt3. Phase 3.

  • 体外研究

  • 体内研究

  • 激酶实验

  • 细胞实验

    ~10 μM

  • 动物实验

    80 mg/kg/day分3种剂量每个3小时腹腔注射

  • 不同实验动物依据体表面积的等效剂量转换表(数据来源于FDA指南)

    动物 A (mg/kg) = 动物 B (mg/kg)×动物 B的Km系数/动物 AKm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。
