细胞实验
细胞系HPAF-II, PaTu 8988S, and Capan-2 cells
方法Cells are plated in growth medium in a 96-well plate at a density of 6,000–12,000 cells per well and treated with DMSO or 1 μM LGK974. After 3 d, the cells are treated with fresh growth medium containing 20 μM EdU, which is included in the Click-iT EdU Alexa
Fluor 488 HCS assay kit, and the plate was incubated for 2 h at 37 °C in a humidified atmosphere containing 5% CO2. Cells are fixed
with final 4% (mass/vol) paraformaldehyde for 30 min, washed with PBS, permeabilized, and stained with 50 μg/mL Hoechst in PBS
for 30 min. After wash, the cells are proceeded to EdU detection according to the instruction of Click-iT EdU assay kit. Triplet wells are
performed for each condition.

动物 A的K系数
例如,依据体表面积折算法,将白藜芦醇用于小鼠的剂量22.4 mg/kg 换算成大鼠的剂量,需要将22.4 mg/kg 乘以小鼠的K系数(3),再除以大鼠的K系数(6),得到白藜芦醇用于大鼠的等效剂量为11.2 mg/kg。
