Bezafibrate is an agonist of PPAR, with EC50s of 90 μM, 55 μM, 110 μM for murine PPARα, PPARγ and PPARδ, and 50 μM, 60 μM, 20 μM for human PPARα, PPARγ and PPARδ, respectively. Bezafibrate (> 200 μM) shows significant cytotoxicity against human retinal microvascular endothelial cells (HRMECs) and human retinal pigment epithelial ARPE-19 cells. Bezafibrate (30-100 μM) suppresses tumor necrosis factor (TNF)α induced inflammatory factors and regulates TNFα induced nuclear factor (NF)-κB transactivation in HRMEC. Bezafibrate inhibits VEGF-induced HRMECs migration, and inhibits interleukin (IL)-1β-induced VEGF secretion of ARPE-19 cells.
