生物活性
Volasertib (BI 6727)是一种高度有效的Plk1抑制剂,IC50为0.87 nM,比作用于Plk2和Plk3选择性高6和65倍。如同BI2536,BI6727是属于dihydropteridinone类化合物的ATP竞争性激酶抑制剂。除了Plk1,BI6727也有效地抑制两个密切相关的激酶Plk2和Plk3,IC50分别为为5 nM和56 nM。 BI6727在浓度高达10 μM时对五十多种激酶均没有抑制活性。

细胞系 | HCT116 and NCI-H460 cells |
方法 | Cell culture and proliferation assays. Cancer cell lines were obtained from the American Type Culture Collection or the German National Resource Center for Biological Material and were cultured according to the supplier’s instructions. Cell proliferation assays were done by incubating cells in the presence of various concentrations of BI 6727 for 72 h and cell growth was assessed by measuring Alamar blue dye (Serotec) conversion in a fluorescence spectrophotometer. Effective concentrations at which cellular growth was inhibited by 50% (EC50) were extrapolated from the dose-response curve fit. |

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。
