生物活性
Olaparib (AZD2281, Ku-0059436)是一种选择性的PARP1/2抑制剂,IC50为5 nM/1 nM,比对Tankyrase-1的作用强300倍。Olaparib是PARP抑制剂,也作用于BRCA1或BRCA2突变。Olaparib对端锚(聚合)酶-1作用效果不大,IC50值大于。Olaparib浓度为30-100 nM作用于SW620细胞,使PARP-1失活。

| 方法 | Potentiation of MMS Cytotoxicity by 47 Determined by the Use of Sulforhodamine B Cell Growth Assays. SW620 cells were seeded in 96-well plates and were left to attach overnight. Cells were preincubated with vehicle control (DMSO) or with a single concentration of KU-0059436 (1, 3, 10, 30, 100 or 300 nM) for 1 h before the addition of increasing concentrations of MMS. Cells were incubated in the presence of each drug combination for 4 days before cell growth was quantified by the use of an SRB assay.44 Data were calculated from triplicate wells as the mean percentage of cell growth relative to KU-0059436-only wells, and (SE and IC50 were calculated by the use of XL-FIT 4 software. SW620 cells showed<24% growth inhibition (>76% cell growth)
when only KU-0059436 was used at concentrations below 300 nM (data not shown). |

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。
