生物活性
AZD4547是一种新型选择性的FGFR抑制剂,靶向作用于FGFR1/2/3,IC50为0.2 nM/2.5 nM/1.8 nM,对FGFR4, VEGFR2(KDR)具有微弱的作用活性,对IGFR, CDK2和p38几乎没有作用活性。与 FGFR1-3相比, AZD4547作用于FGFR4,活性微弱,IC50为165 nM。AZD4547 只抑制重组 VEGFR2 (KDR) 激酶活性, IC50为 24 nM,在体外选择性作用于一组多种代表性的人类激酶。0.1 μM AZD4547 作用于一系列重组激酶,包括 ALK, CHK1, EGFR, MAPK1, MEK1, p70S6K, PDGFR, PKB, Src, Tie2,和 PI3K,没有作用活性。

细胞系 | MCF-7 cell line |
方法 | In vitro cell-cycle and apoptotic induction analysis Cell lines were incubated with fixed concentrations of AZD4547 for 72 hours. For fluorescence-activated cell sorting (FACS), cells were fixed with 70% ethanol and then incubated with propidium iodide/RNase A (Sigma) labeling solution. Cell-cycle profiles were assessed with a FACSCalibur instrument and CellQuest analysis software (Becton Dickinson). For apoptotic analysis, cells and media were gently harvested and centrifuged, followed by washing of cell pellets. Cells were then processed for Annexin V-fluorescein isothiocyanate (FITC) staining and propidium iodide uptake according to the manufacturer's instructions (Abcam). The proportion of cells staining positive for Annexin V were then assessed with a FACSCalibur instrument and quadrant sorting was done by CellQuest analysis software (Becton Dickinson). |

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。
