JK-P3 is a potent and pan VEGFR2 inhibitor, with IC50s of 7.83 μM, 27 μM and 5.18 μM for VEGFR2, FGFR1 and FGFR3, respectively. JK-P3 can inhibit VEGF-A-stimulated VEGFR2 activation and intracellular signalling, also inhibits endothelial monolayer wound closure and angiogenesis, as well as fibroblast growth factor receptor kinase activity in vitro. JK-P3 has anti-angiogenic activity[1].

| In Vitro | JK-P3 (0.01-10 μM; 1 hour) inhibits VEGF-A-mediated VEGFR2 phosphorylation and downstream signalling[1]. JK-P3 (0.01-10 μM; 16 hours) dose not inhibit HUVEC cell proliferation at 0.01~1 μM, and shows slight inhibitory activity at 10 μM[1]. JK-P3 (1 and 10 μM; 1 hour) does not significantly inhibit VEGF-A-stimulated endothelial tube formation at 1 µM, but almost completely inhibits the ability of endothelial cells to form into elongated hollow tubes in the presence of VEGF-A at 10 µM[1]. Western Blot Analysis Cell Line: Primary endothelial cells (treated for 7.5 min with 25 ng/mL VEGF-A)[1] Concentration: 0.01, 0.1, 1 and 10 μM Incubation Time: 1 hour Result: Almost completely inhibited VEGFR2 Y1175 phosphorylation, also inhibited VEGF-A-stimulated PLCγ1, Akt and ERK1/2 phosphorylation. Cell Proliferation Assay Cell Line: HUVEC[1] Concentration: 0.01, 0.1, 1 and 10 μM Incubation Time: 16 hours Result: Failed to inhibit endothelial cell proliferation at 0.01~1 μM but elicited a small but significant increase in cell proliferation at certain lower concentrations. |
