生物活性
Dinaciclib (SCH727965)是一种新型有效的CDK抑制剂,作用于CDK2, CDK5, CDK1和CDK9,IC50分别为1 nM, 1 nM, 3 nM和4 nM,也抑制胸甘(dThd) DNA摄入。Dinaciclib抑制CDK1和CDK9 效果差不多,但是抑制CDK2和CDK5效果则分别强12和14倍。Dinaciclib作用于A2780细胞,有效抑制的DNA复制,抑制胸甘(dThd)DNA摄入,IC50为4 nM。Dinaciclib 浓度大于6.25 nM时,强抑制Rb在Ser 807/811位点磷酸化。

细胞系 | A2780 cells |
方法 | dThd uptake growth inhibition assay. A2780 cells were maintained in DMEM (Cellgro) plus 10% fetal bovine serum (HyClone) and passaged twice weekly by detaching the monolayer with trypsin-EDTA (Life Technologies). One hundred microliters of A2780 cells (5 × 103 cells) were added per well to a 96-well Cytostar-T plate (Amersham) and incubated for 16 to 24 hours at 37°C. Compounds were serially diluted in complete media plus 2% 14C-labeled dThd (Amersham). Media were removed from the Cytostar T plate; 200 μL of various compound dilutions were added in quadruplicate; and the cells were incubated for 24 hours at 37°C. Accumulated incorporation of radiolabel was assayed using scintillation proximity and measured on a TopCount (Packard/Perkin-Elmer Life Sciences). The percentage of dThd uptake inhibition, relative to a vehicle control, was calculated and plotted on log-linear plots to allow derivation of IC50 values. |

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。
