Abstract
Age-related macular degeneration (AMD), often triggered by endothelial barrier disruption through vascular endothelial growth factor (VEGF), is a leading cause of blindness. This study investigated the inhibitory effects of phenolic compounds on VEGF-induced endothelial cell proliferation, migration, angiogenesis, and permeability using human retinal microvascular endothelial cells (hRECs). Thirty-seven polyphenolic compounds were selected from various databases based on their antioxidant properties, abundance in food, and solubility. These compounds significantly reduced migration, tube formation, and endothelial permeability in VEGF-stimulated hRECs. Notably, formononetin, eriodictyol, biochanin A, and p-coumaric acid were more effective in suppressing VEGF-induced angiogenesis and endothelial permeability than lutein. Molecular docking simulations revealed that formononetin, eriodictyol, and biochanin A had relatively lower binding energies with VEGF receptor 2 (VEGFR2) than lutein and sorafenib. These findings highlight the potential of phenolic compounds to be used as VEGFR2 inhibitors and an alternative strategy for preventing AMD.
