生物活性
dBET1 treatment down regulates MYC and PIM1 transcription. dBET1 also induces a potent and superior inhibitory effect on MV4;11 cell proliferation at 24 hours (measured by ATP content, IC50= 0.14 μM, compare to IC50= 1.1 μM with JQ1).
In vivo, administration of dBET1 attenuates tumor progression as determined by serial volumetric measurement, and decreases tumor weight assessed post-mortem. Acute pharmacodynamic degradation of BRD4 is observed four hours after a first or second daily treatment with dBET1 (50 mg/kg IP). A statistically significant destabilization of BRD4, down regulation of MYC and inhibition of proliferation is observed with dBET1 compare to vehicle control in excised tumors.

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。
