生物活性
CP-724714是一种有效的，选择性的HER2/ErbB2抑制剂，IC50为10 nM，比作用于EGFR， InsR， IRG-1R， PDGFR， VEGFR2， Abl， Src， c-Met等选择性高640多倍。CP-724,714明显选择性作用于EGFR，IC50为6.4 μM。CP-724,714作用于IR,IGF-1R,PDGFRβ,VGFR2,Abl，Src,c-Met，c-jun NH2端激酶(JNK)-2,JNK-3,ZAP-70,周期蛋白依赖激酶(Cdk)-2,和Cdk-5效果要低1000倍以上。CP-724,714作用于含erbB2激酶域的嵌合体，有效降低EGF诱导的自磷酸化，IC50为32 nM,但是作用于转染EGFR的NIH3T3细胞效果明显低很多。

Cells were seeded in duplicate at 5,000 to 10,000 per well in 24-well plates. The day after plating, CP-724,714 was added by titrating over six or more dilutions from 10 μmol/L down. Control wells without drug were seeded as well. Cells were grown for 6 to 7 days, at which time surviving cells were counted. After trypsinization, cells were placed in isotone solution and counted immediately using a Coulter Z2 particle counter (Beckman Coulter, Inc.). Growth inhibition was calculated [(1- experimental value / control value) × 100] for each concentration. Dose-response curves were repeated at least twice and averaged. IC50 values were calculated using Calcusyn Software (Biosoft). |

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。
