生物活性
ENMD-2076选择性作用于Aurora A和VEGFR(Flt3),IC50分别为14 nM和1.86 nM,作用于Aurora A比作用于Aurora B选择性高25倍,对VEGFR2/KDR和VEGFR3, FGFR1和FGFR2和PDGFRα作用效果稍弱。ENMD-2076有效作用于血管生成的多种激酶,包括VEGFR2/KDR 和VEGFR3, FGFR1和FGFR2, 及PDGFRα,IC50 为1.86到120 nM。ENMD-2076抑制多种人类实体瘤和血癌细胞系,IC50为0.025 到0.7μM, 诱导细胞凋亡,且使细胞周期停止在G2/M 期。ENMD-2076 作用于乳腺癌,结肠癌,黑色素瘤,白血病,多发性骨髓瘤细胞系移植瘤模型,诱导肿瘤衰退或完全抑制肿瘤生长。

细胞系 | solid tumor cell lines and HUVECs, human leukemia cell lines |
方法 | Cell and proliferative assays Cell lines were routinely tested for mycoplasma and used at low passage numbers (<10). The antiproliferative effect of ENMD-2076 on adherent tumor cell lines was measured by plating 500 cells per well in a 96-well plate and incubating with 9 doses of compound, spanning 0.3 nmol/L to 125 μmol/L, for 96 hours. Cellular proliferation was measured using the sulforhodamine B (SRB; Sigma Aldrich) assay (10). The leukemia-derived, nonadherent cell lines were assayed by plating 5,000 cells per well in a 96-well plate. The cells were incubated with 9 doses of compound, spanning 0.3 nmol/L to 125 μmol/L, for 48 hours and then survival was assayed using the Alamar Blue reagent (Invitrogen) according to the manufacturer’s instructions. To measure the effect of ENMD-2076 on VEGF- and fibroblast growth factor (FGF)-induced proliferation of human umbilical vein endothelial cell (HUVEC), cells were serum starved for 6 hours, then treated with ENMD-2076 free base, and stimulated with 5 ng/mL bFGF or 25 ng/mL VEGF (R and D Systems) for 72 hours. Cell proliferation was measured using WST-1 (Roche Applied Science) according to the manufacturer’s instructions. |

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。
