生物活性
GSK461364抑制纯化的Plk1,Ki为2 nM,比作用于Plk2/3选择性高1000倍。GSK461364作用于非细胞分裂细胞,从多起点抑制癌细胞系增殖。 野生型p53的RNA沉默提高GSK461364的抗增殖活性。许多癌症疗法对p53野生型患者更有效, p53缺陷肿瘤对GSK461364的高度敏感性可提供治疗肿瘤的机会。

方法 | Cell lines were obtained from American Type Culture Collection and grown in the recommended media at 37°C, 5% CO2 in a humidified incubator. Cells were plated in triplicate 96-well microtiter plates at 1,000 cells per well in culture media. GSK461364A dissolved in DMSO or negative control (0.1% DMSO) were added the following day, and one plate was harvested with 50 μL of CellTiter-Glo (Promega) for a time 0 (T = 0) measurement. Remaining duplicate cell plates were typically incubated for 72 h. Cells were then lysed with 50 μL CellTiter-Glo, and chemiluminescent signal was read on the Wallac EnVision 2100 plate reader. All data were normalized to signal at time of compound addition (T = 0). Curves were analyzed using the XLfit (IDBS Ltd.) curve-fitting tool for Microsoft Excel to determine the gI50 (concentration of 50% growth inhibition relative to T = 0 and Ymax values), the gI-maximum (concentration giving maximum growth inhibition), and the Ymin (bottom of the four-parameter curve at gI-maximum). |

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)
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
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,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。
