| 细胞系 | ALL cells and normal T lymphocytes |
| 方法 | Growth inhibition assay The inhibitory effect of tubacin on ALL cells and normal T lymphocytes was assessed by colorimetric assay, 3-(4,5-dimethylthiazol-e-yl)- 2,5-diphenyl tetrazolium bromide (MTT; Sigma). Only active mitochondria dehydrogenase enzymes can perform cleavage of a tetrazolium ring, and therefore the amount of purple formazan generated by cells with a drug was compared with the amount of formazan produced from non-treated cells. Absorbance readings at a wavelength of 550 nm were taken on a spectrophotometer (Titertek Multiskan MCC Type 341). Cells from 72 h cultures were incubated with 10 μL of 5 mg/mL MTT for 2 h, followed by 100 μL isopropanol that contained 0.1 N HCl. Normal T lymphocytes were incubated with MTT for 30–37 min. All experiments were performed in triplicate. |

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。
