生物活性
Zotiraciclib (TG02, SB1317) is an orally bioavailable, brain penetrant multi-kinase inhibitor of CDK2, JAK2, and FLT3 with IC50 values of 13, 73, and 56 nM, respectively. Zotiraciclib inhibits cell proliferation concentrations in HCT-116 (IC50=0.079 μM) and HL-60 (IC50=0.059 μM).
In vivo, treatment with Zotiraciclib (SB1317) at 75 mg/kg po q.d. 3×/week significantly inhibits the growth of tumors with a mean TGI of 82%, while the lower dose of 50 mg/kg po 3×/week is marginally effective. Treatment with Zotiraciclib using either regime significantly inhibits the growth of tumors with mean TGIs of 42% and 63% for the oral and ip delivery methods, respectively.

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
