细胞实验
细胞系MYCN amplified neuroblastoma cell lines
方法Pharmacologic growth inhibition LEE011 was provided by Novartis pharmaceuticals. A panel of neuroblastoma cell lines, selected based upon prior demonstration of substrate adherent growth, was plated in triplicate on the Xcelligence Real-Time Cell Electronic Sensing system (ACEA Biosciences) and treated 24 hours later with a four-log dose range of inhibitor or with a DMSO control. Cell indexes were monitored continuously for ~100 hours, and IC50 values were determined as follows: Growth curves were generated by plotting the cell index as a function of time and were normalized to the cell index at the time of treatment for a baseline cell index of 1. The area under the normalized growth curve from the time of treatment to 96 hours post-treatment was then calculated using a baseline area of 1 (the cell index at the time of treatment). Areas were normalized to the DMSO control, and the resulting data were analyzed using a non-linear log inhibitor vs. normalized response function (Graphpad). All experiments were repeated at least once.

体表面积 (m2)0.0070.0250.150.050.020.5

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。
