生物活性
BI-D1870是一种ATP-竞争性S6 ribosome抑制剂，作用于RSK1/2/3/K4，IC50分别为31 nM/24 nM/18 nM/15 nM，作用于RSK比作用于MST2， GSK-3β， MARK3， CK1和Aurora B选择性高10到100倍。BI-D1870抑制RSK1，RSK2，RSK3和RSK4，IC50为10-30 nM，但在100倍更高浓度时，也不显著抑制10种其他AGC激酶成员和40多个其他蛋白激酶。BI-D1870可渗透细胞的，作用于人类胚胎肾293细胞和大鼠-2细胞，可抑制RSK介导佛波酯和EGF诱导的糖原合酶激酶-3β和LKB1的磷酸化。BI-D1870作用于六种其他AGC激酶，不影响激动剂触发的底物磷酸化。

| 方法 | Prior to stimulation, cells were cultured in the absence of serum for 16 h. Inhibitors were dissolved in DMSO at a 1000-fold higher concentration than they were used at. These inhibitors, or the equivalent volume of DMSO as a control, were added to the tissue culture medium 30 min prior to stimulation, unless indi-cated otherwise. The final concentration of DMSO in the culture medium was 0.1% and had no effect on agonist-induced activ-ation or phosphorylation of any of the substrates examined. The cells were stimulated with the indicated agonists and lysed in 1 ml of ice-cold Lysis Buffer, and centrifuged at 16000 g at 4 °C for 5 min. The supernatants were frozen in liquid nitrogen and stored at –80 °C until use. Protein concentrations were determined using the Bradford method with BSA as the standard. |

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。
