Dysregulated angiogenesis is implicated in several pathologies, including cancer and age‐related macular degeneration. A potential antiangiogenic strategy consists in developing VEGF receptor ligands capable of preventing VEGF binding and the subsequent activation of these receptors. Herein, we describe the structure‐based design of a VEGF‐mimicking peptide, VG3F. This 25‐mer peptide was doubly cyclized, on‐resin, by formation of both a disulfide bridge and an intramolecular amide bond to constrain it to adopt a bioactive conformation. Tested on in vitro assays, VG3F was able to prevent VEGF binding to VEGF receptor 1 and inhibit both VEGF‐induced signal transduction and cell migration.
