生物活性
AZD7762是一种有效的，选择性的Chk1抑制剂，IC50为5 nM，也作用于Chk2也同等有效，对CAM， Yes， Fyn， Lyn， Hck和Lck作用效果稍弱。AZD7762是Chk1选择性抑制剂, 通过与Chk1的ATP结合位点可逆结合而抑制cdc25C肽段的Chk1磷酸化，IC50 为5 nM，Ki为 3.6 nM。AZD7762诱导细胞周期停滞，EC50为0.620 μM, 且通过阻断cdc25A依赖chk1的降解 和Cyclin A的激活，显著废除Camptothecin诱导的G2期停滞，EC50为10 nM。300 nM AZD7762增强Gemcitabine作用于SW620的抗癌活性，也增强 Topotecan作用于MDA-MB-231 的抗癌活性，通过降低 GI50 值，分别从24.1 nM和2.25 μM 降到1.08 nM 和0.15 μM。

HT29 cells (3 × 105) were seeded in 96-well plates and incubated overnight. Cells were treated for 2 h with camptothecin (topoisomerase I inhibitor; 0.07 μg/mL) to induce the G2 checkpoint. Cells were then treated for 20 h with vehicle (0.5% DMSO) or caffeine (4 mmol/L; positive control) plus nocodazole (1 μg/mL) or a 12-point titration of AZD7762 (12.5 μmol/L to 6 nmol/L) plus nocodazole. Nocodazole alone-treated cells with no camptothecin pretreatment were used to determine the maximum mitotic index. Cells were fixed with 3.7% formaldehyde for 1 h, permeabilized with PBS containing 0.05% Triton X, and incubated with anti-phH3 antibody for 1 h followed by Alexa Fluor 488 anti-rabbit (Molecular Probes) and Hoechst stain for 1 h. Mitotic index was determined on the ArrayScan and expressed as the percentage of cells undergoing mitosis. The EC50 was calculated by concentration-response curve fitting using three-variable logistical equations within XLfit (model 205) with the curve bottom constrained to 0 and the top constrained to 100 by nocodazole alone treatment. |

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。
