生物活性
Neratinib (HKI-272)是一种高度选择性的HER2和EGFR抑制剂，IC50分别为59 nM和92 nM；微弱抑制KDR和Src，对Akt，CDK1/2/4， IKK-2， MK-2， PDK1， c-Raf和c-Met没有显著的抑制作用。Neratinib微弱抑制酪氨酸激酶KDR 和Src，IC50分别为0.8 μM 和 1.4 μM,与 HER-2相比，活性分别弱14和24倍。Neratinib 作用于其他丝-苏氨酸激酶如Akt, cyclin D1/cdk4, cyclin E/cdk2, cyclin B1/cdk1, IKK-2, MK-2, PDK1, c-Raf, 和Tpl-2，以及酪氨酸激酶c-Met没有活性。Neratinib选择性抑制转染 HER-2 (3T3/neu)的3T3细胞增殖,也抑制两种其他 HER-2-过表达的SK-Br-3和 BT474 cells细胞增殖，IC50为 2-3 nM,与未转染的3T3细胞及 EGFR-和 HER-2阴性的MDA-MB-435 和 SW620细胞相比，效果高230倍以上。

Cells were plated in 96-well tissue culture plates (3T3, 3T3/neu, 5000 cells/well; A431, SK-Br-3, BT474, MDA-MB-435, and SW620, 10,000 cells/well). The following day, dilutions of compound (0.5 ng/ml–5 μg/ml) were added, and cells were cultured for 2 days (6 days for BT474). Cell proliferation was determined using sulforhodamine B, a protein binding dye. Briefly, cells were fixed with 10% trichloroacetic acid and washed extensively with water. Cells were then stained with 0.1% sulforhodamine B (Sigma-Aldrich) and washed in 5% acetic acid. Protein-associated dye was solubilized in 10 mm Tris, and absorbance was measured at 450 nm (Victor2). Inhibition of cell proliferation was calculated using the formula: percentage of inhibition = 100 – 100 (Td – To/Tc – To), where Td is the absorbance of drug treated cells, Tc is the absorbance of untreated cells, and To is the absorbance at the time of drug addition. To values were determined by plating cells separately and fixing them at the time of drug addition. The concentration of compound which inhibits cell proliferation by 50% (IC50) was determined from inhibition curves. |

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。
