描述 | The vascular endothelial growth factor (VEGF) receptors are important angiogenesis mediators that have been considered as a hallmark of tumor growth and metastasis. JNJ-3815847 is a potent and selective VEGFR-2 inhibitor with an IC50 value of 40nM. It showed no anti-proliferative effects on human cancer cell lines HCT116 and A375 at 100μM. In human umbilical vein endothelial cells (HUVECs), JNJ-38158471 (1 - 500nM) potently inhibited VEGF-dependent auto-phosphorylation of VEGFR-2 in a concentration-dependent manner (90% inhibition at 500nM). JNJ-38158471 treatment (50 - 1000nM) also significantly inhibited VEGF-dependent HUVEC migration. Oral administration of mice with JNJ-38158471 (10 or 100mg/kg/day) for 6 days caused a dose-dependent inhibition of VEGF-dependent blood vessel formation (15% and 83% inhibition, respectively) compared to the vehicle controls. In a mouse A375 melanoma model, treatment with JNJ-38158471 (100mg/kg/day) significantly inhibited tumor growth (90% inhibition) at 28 days of continuous dosing[1]. |
