| 方法 | Cell growth and viability assay. Human cancer cell lines were purchased from American Type Culture Collection and plated at 5,000 to 10,000 per well in 96-well plates with culture medium, as suggested by the provider. The cells were then incubated with compounds at various concentrations for 120 h. Growth inhibition was assessed by ATP content assay using the Perkin-Elmer ATPlite kit. Briefly, a 25-μL cell lysis solution was added to the 50-μL phenol red–free culture medium per well to lyse cells and stabilize ATP. Then 25-μL substrate solutions were added to the wells, and subsequently, luminescence was measured with a TopCount liquid scintillation analyzer (Perkin-Elmer). Values were expressed as a percentage relative to those obtained in untreated controls. IC50 values were calculated using PRISM software (GraphPad Software) with sigmoidal dose-response curve fitting. |

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。
