生物活性
Bosutinib (SKI-606)是一种新型的Sarcoma/Abelson (Src/Abl)酪氨酸激酶双重抑制剂，其IC50分别为1.2 nM和1 nM。Bosutinib作用于Src比非Src家族激酶选择性高，IC50为1.2 nM,且有效抑制Src依赖的细胞增殖，IC50为100 nM。 Bosutinib 显著抑制Bcr-Abl阳性白血病细胞系KU812, K562, 和MEG-01 而不是 Molt-4, HL-60, Ramos, 和其他白血病细胞系的增殖，IC50分别为5 nM, 20 nM,和20 nM，比 STI-571更有效。与STI-571类似, Bosutinib 作用于Abl-MLV转化纤维，具有看增殖活性，IC50为 90 nM。

| 方法 | cell lines were obtained from the American Type Culture Collection. The KU812 line was obtained from the European Collection of Cell Cultures. K562 and KU812 cell lines were maintained in RPMI 1640 supplemented with 10% FCS, glutamine, and nonessential amino acids (Life Technologies, Inc.). Rat 2 and Abl-MLV-transformed Rat 2 cells were maintained in high-glucose DMEM supplemented with 10% FCS. For proliferation assays, cells were exposed to compound for 72 h, and relative proliferation was measured with either 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxy-phenyl)-2-(4-sulfonyl)-2H-tetrazolium (Promega) or Cell-Glo (Promega). Anchorage-independent proliferation of Abl-MLV-transformed fibroblasts was measured in 96-well ultra-low binding plates (Costar) treated with Sigmacote (Sigma) to block residual cell attachment. Data analysis for IC50 calculations was performed with the LSW Data Analysis Package plug-in for Excel (Microsoft). For biochemical assays, cells were incubated with compound or DMSO alone for 4 h. Cells were prepared for FACS analysis as described in the CycleTest Plus DNA reagent kit (Becton Dickinson) and analyzed on a fluorescence-activated cell sorter flow cytometer. |

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。
