SU 1498是一种选择性的VEGFR2抑制剂，抑制Flk-1的IC50值为700 nM。
In vitro: SU1498 stimulates accumulation of phosphorylated ERKs in human umbilical vein endothelial cells and in human aortic endothelial cells in a manner that is dependent on the functioning of the upstream components of the MAPK pathway, B-Raf and MEK kinases. SU 1498 blocks signal transduction from VEGFR2 in MS1 VEGF cells. In the presence of SU1498, levels of Ets-1 are decreased, suggesting that VEGF-VEGFR-2 interactions contributed to baseline levels of Ets-1 expression, and interruption of this autocrine interaction with SU1498 led to decreased expression of Ets-1. SU1498 treatment significantly impacts U87 cell proliferation and apoptosis. SU-1498 induces a marked increase in lipids and a decrease in glycerophosphocholine.

| 方法 | For cell proliferation assay, SU1498 is prepared as a stock solution of 30 mM in DMSO, then diluted with culture medium to working concentrations before use. U87 cells are seeded in 24-well plates (30,000 cells/well) and allowed to attach overnight. Cells are then treated for 24 or 72 h with different concentrations of Bevacizumab (from 10 ng/mL to 250 μg/mL) or SU1498 (from 1 μM to 30 μM) in triplicate wells. The cell viability is then assessed with the MTT assay. |

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。
