方法 |
MTT (viability) assay CML cells were seeded in 96-well plates (2*104 cells/well) and WP1130, imatinib mesylate, or dasatinib (0.08-10 μ M) were added in a final volume of 100 μL medium. Plates were incubated at 37°C for 72 hours, after which 20 μL of 3-4,5-dimethylthiazolyl-2-2, 5-diphenyltetrazolium bromide (MTT) reagent (Sigma; stock 5 mg/mL) was added, and the plates were incubated at 37°C for another 2 hours. Cells were lysed with 100 L lysis buffer (20% sodium dodecyl sulfate [SDS] in 50% N, N-dimethylformamide adjusted to pH 4.7 with 80% acetic acid and 1 M hydrochloric acid; final concentration of acetic acid was 2.5% and hydrochloric acid was 2.5%) and incubated for 6 hours. The optical density of each sample at 570 nm was determined with a SPECTRA MAX M2 plate reader (Molecular Devices, Sunnyvale, CA). |

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。
