| 方法 | MTT (viability) assay CML cells were seeded in 96-well plates (2*104 cells/well) and WP1130, imatinib mesylate, or dasatinib (0.08-10 μ M) were added in a final volume of 100 μL medium. Plates were incubated at 37°C for 72 hours, after which 20 μL of 3-4,5-dimethylthiazolyl-2-2, 5-diphenyltetrazolium bromide (MTT) reagent (Sigma; stock 5 mg/mL) was added, and the plates were incubated at 37°C for another 2 hours. Cells were lysed with 100 L lysis buffer (20% sodium dodecyl sulfate [SDS] in 50% N, N-dimethylformamide adjusted to pH 4.7 with 80% acetic acid and 1 M hydrochloric acid; final concentration of acetic acid was 2.5% and hydrochloric acid was 2.5%) and incubated for 6 hours. The optical density of each sample at 570 nm was determined with a SPECTRA MAX M2 plate reader (Molecular Devices, Sunnyvale, CA). |

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。
