生物活性
AZD8931 (Sapitinib)是一种可逆的，ATP竞争性EGFR， ErbB2和ErbB3抑制剂，IC50分别为4 nM， 3 nM和4 nM，作用于NSCLC细胞比Gefitinib或Lapatinib更有效，作用于ErbB家族比作用于MNK1和Flt选择性强100倍。AZD8931作用于NSCLC和SCCHN 细胞系的效果不同。AZD8931高度选择性作用于 PC-9细胞(EGFR 激活突变型),GI50为0.1 nM，而低活性作用于 NCI-1437细胞，GI50 >10 μM。与lapatinib 或 gefitinib相比，AZD8931作用于 PE/CA-PJ41, PE/CA-PJ49, DOK 和FaDu细胞，更有效作用于p-EGFR, p-erbB2 和 p-erbB3。

| 方法 | cell viability assay. To determine their antiproliferative activity against cell lines grown in vitro, AZD8931, gefitinib, and lapatinib were tested in a panel of NSCLC and SCCHN cell lines. Cells were incubated for 96 h with a suitable range of concentrations of drug to ensure accurate estimation of the inhibitor concentration required to give 50% growth inhibition (GI50; typically between 0.001-10 μmol/L). Viable cell number was determined by 4 h of incubation with MTS Colorimetric Assay reagent (Promega) and absorbance measured at 490 nm on a spectrophotometer (Molecular Devices). Each experiment was carried out in triplicate for each drug concentration and data are presented as geometric means. Sensitivity groupings of GI50 data were<1 μmol/L (classed as sensitive), 1 to 7 μmol/L (classed as intermediate), and >7 μmol/L (classed as resistant). |

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。
