生物活性
AZD9291 is an oral, irreversible, and mutant-selective EGFR inhibitor with IC50 of 12.92, 11.44 and 493.8 nM for Exon 19 deletion EGFR, L858R/T790M EGFR, and WT EGFR, respectively. In vivo,AZD9291 shows significantly more potent inhibition of proliferation in mutant EGFR cell lines when compared with wild-type.AZD9291(5mg/kg p.o.) causes profound regression of tumors across EGFRm+ (PC9) and EGFRm+/T790M (H1975) tumor models with profound inhibition of EGFR phosphorylation and key downstream signaling pathways such as AKT and ERK .

| 方法 | In vitro EGFR phosphorylation assays Cells were treated for 2 h with a dose-response of each drug. Wild-type cells were stimulated for 10 minutes with 25 ng/ml of EGF before lysis. Level of EGFR phosphorylation was quantified in cell extracts using a modified R&D Systems DuoSet Human phospho-EGFR ELISA (36). |

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。
