Fig. 9. Inhibitory effects of compound 1 on the phosphorylation of VEGFR2, AKT, and ERK. (A)Western blot analysis of phospho-(B) VEGFR2, (C) AKT, (D) ERK1/2 levels in HUVECs treated with compound 1 at indicated concentrations. β-actin was used as a loading control. Data are presented as mean ± SEM from three independent experiments. *P <0.05, **P <0.01 vs. VEGFtreated control.
