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。

方法 | Cell proliferation assays. 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). |

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。
