细胞系 | B16F10 cells |
方法 | HGF-induced migration assay. B16F10 cells (2 *105) were seeded onto 0.8 Am membranes in the top chamber of a 96-well Transwell plate in DMEM containing a serial dilution of EXEL-2880 and 0.1% FBS. DMEM containing HGF (50 ng/mL), 0.2% FBS, and EXEL-2880(foretinib) was added to the bottom chamber, and after 24 h, the medium was removed and Accutase (ISC BioExpress) was added to the bottom chamber. After 30 min, cells were transferred to a V-bottomed 96-well plate, centrifuged, and resuspended in HBSS containing 2 mg/mL calcein-AM (Molecular Probes). After incubation for 30 min, cells were transferred into a black 96-well plate. Fluorescence emission was measured at 480 nm using an excitation wavelength of 520 nm and imaged with a fluorescence microscope. |

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。
