生物活性
BGT226 (NVP-BGT226)是一种新型I型PI3K/mTOR抑制剂，作用于PI3Kα/β/γ，IC50为4 nM/63 nM/38 nM。生长抑制实验显示NVP-BGT226具有抗肿瘤活性。NVP-BGT226显著抑制细胞生长，IC50 < 20 nM。NVP-BGT226在纳摩尔浓度时也诱导癌细胞凋亡，IC50≤25 nM。

Cells in the logarithmic growth phase were cultured at a density of 5,000 to 20,000 cells per milliliter per well in a 24-well plate. The cells were exposed to various concentrations of BGT226 for 3 generation times. At the end of the incubation period, cells were fixed and stained with 50% ethanol containing 0.5% methylene blue for 30 minutes. The resulting colored residues were dissolved in 1% N-lauroyl-sarcosine, and optical density was read at 550 nm using a microplate reader. The IC50 value resulting from 50% inhibition of cell growth was calculated graphically as a comparison with control groups. Each point represents the average of at least 3 independent experiments run in duplicate. |

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。
