生物活性
Rociletinib (CO-1686，AVL-301)是一种不可逆的，突变选择性的EGFR抑制剂，作用于EGFRL858R/T790M和EGFRWT， Ki分别为21.5 nM和303.3 nM。In NSCLC cells with acquired resistance to CO-1686 in vitro, there was no evidence of additional mutations or amplification of the EGFR gene, but resistant cells exhibited signs of epithelial-mesenchymal transition and demonstrated increased sensitivity to AKT inhibitors. In vivo, Rociletinib (CO-1686) caused dose-dependent and significant tumor growth inhibition in all EGFR-mutant models as well as human EGFRL858R- and EGFRL858R/T790M-expressing transgenic mice. Rociletinib (CO-1686) is approximately 22-fold selective over WT EGFR (kinactt/Ki = (1.12 ± 0.14) x 104 M-1s-1).

| 方法 | Cell signaling analysis of HCC827 and HCC827-EPR HCC827 and HCC827-EPR cells were seeded at 1.5×106 cells per 10 cm2 dish in RPMI 1640, 10 % FBS, 2 mM L-glutamine, and 1% P/S and allowed to adhere overnight. Cells were treated with DMSO, 2 μM CO-1686, or 2 μM erlotinib for 72 hours and lysed. Lysis buffer contained 1X phenylmethanesulfonyl fluoride (Sigma; St. Louis, MO), 1X cell extraction buffer (Life Technologies), 1X protease inhibitor cocktail (Enzo Life Sciences; Farmingdale, NY), 1X phosphatase inhibitor cocktails I and II (EMD Chemicals; Gibbstown, NJ). Total protein concentration was determined using a standard Bradford and measured on a NanoDrop 2000 spectrophotometer (Thermo Scientific; Waltham, MA). Western blotting was performed on cell lysates normalized to 25 μg total protein in loading buffer (LI-COR; Lincoln, NE). Normalized lysates were run on SDS/PAGE and transferred to a nitrocellulose membrane (Life Technologies). The membrane was incubated in Qentix signal enhancement solution (Thermo Scientific), blocked, and incubated overnight at 4°C with primary antibodies (1:1000) from Cell Signaling (Danvers, MA). Membranes were washed, incubated with IRDye(R) secondary antibodies (LI-COR), washed again, and imaged on an Odyssey Fc (LI-COR). |

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。
