生物活性
ABT-263 (Navitoclax)是一种有效的Bcl-xL， Bcl-2和Bcl-w抑制剂，Ki分别为≤0.5 nM，≤1 nM和≤1 nM，但与Mcl-1和A1结合微弱。ABT-263有效抑制Bcl-2蛋白家族，用荧光偏振分析法测试ABT-263作用于Bcl-xL, Bcl-2和 Bcl-w时，Ki分别为0.5, 1和1 nM。ABT-263结构上与ABT-737相关。ABT-263阻断Bcl-2 和Bcl-XL与凋亡前体蛋白相互作用。

| 方法 | Flourescence Activated Cell Sorting (FACS) for death assays and cell cycle analysis Cells were plated in triplicate in 6-well plates or 6-cm dishes to reach ~30-40% confluency the next day. On the next day, cells were treated with the indicated drugs or no drug control. Apoptosis and cell cycle experiments were performed essentially as previously described and analyzed on a BD LSR III (Becton Dickenson, Franklin Lanes, NJ). The cell cycle experiments were gated to include only viable cells in order for the cell cycle distribution to be determined from this population. For apoptosis assays, the number of cells in quadrants II and IV (Annexin positive) were counted as apoptotic, where cells with subG0/G1 DNA3 were quantified and counted as apoptotic following staining with PI. The Annexin stain was conjugated to FITC and the analysis was done on a Guava easyCyte flow cytometer (EMD Millipore (Temecula, CA)). In the engineered H1048 cells, apoptosis determined by ABT-263 treatment and combination ABT-263/AZD8055 treatment were performed within the same experiment. |

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。
