IC50: 8 μM (125I-VEGF-A binding to PAE/NRP1); 3 μM (bt-VEGF-A binding to purified NRP1 b1 domain)[1].
EG00229 (Compound 2; 0-100 μM; 48 hours; A549 cells) treatment causes a significant reduction in cell viability over a 48 hours incubation[1].
EG00229 (Compound 2) demonstrates inhibition of VEGF-A binding to NRP1 and attenuates VEGFR2 phosphorylation in endothelial cells. Inhibition of migration of endothelial cells is also observed in HUVECs[1].
EG00229 (Compound 2) selectively inhibits radiolabeled 125I-VEGF-A binding to porcine aortic endothelial (PAE)/NRP1, but not VEGFR2-expressing cells, with an IC50 of 8 μM. EG00229 also inhibits VEGF-A binding to lung carcinoma A549 and prostate carcinoma DU145 cells, which express NRP1, but not VEGFR1 and VEGFR2, with similar potency. Binding of VEGF-A to human umbilical vein endothelial cells (HUVECs), which express VEGFR2, VEGFR1, and NRP1, is also inhibited by EG00229 with an IC50 of 23 μM[1].
