生物活性
OSU-03012 (AR-12)是一种有效的重组PDK-1抑制剂，IC50为5 μM，比OSU-02067作用效果高2倍。OSU-03012诱导PC-3细胞凋亡，IC50为5 μM，且降低免疫沉淀的p70S6K的活性。Celecoxib完全抑制肿瘤细胞生长,浓度至少需要50 μM，而OSU-03012浓度为3-5 μM时即可完全抑制多种肿瘤细胞生长。 与作用于正常的胶质细胞相比，OSU-03012作用于神经胶质瘤细胞更有效促进细胞死亡。

| 方法 | Cell proliferation assay VS and HMS-97 cells were grown in polylysine/laminin-coated 96-well plates (5 × 103 to 1 × 104 per well). After incubation at 37°C for 24 hrs, cells were treated with various concentrations of OSU-03012 or DMSO as a vehicle control at 37°C for another 48 hrs. To assess cell proliferation, the CellTiter 96(R)AQueous One Solution Cell Proliferation Assay (Promega) was used according to the manufacturer’s instructions. Briefly, 20μl of CellTiter 96(R) AQueous One Solution Reagent were added to each well and incubated at 37°C for 1 to 4 hrs. The amount of colored formazan produced in the cells was measured at 490nm using a Victor3 1420 Multilabel Counter (Perkin Elmer). The percentage of cell proliferation was plotted against the concentrations of OSU-03012, and the IC50 (defined as the drug concentration at which the population of viable cells was reduced by 50%) was determined using CalcuSyn software (Biosoft). The experiments were replicated six times, and the mean IC50 was calculated. |

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。
