Risuteganib is an anti-integrin peptide and a derivative of RGD peptide .1 Risuteganib (400 μM) protects against hydroquinone-induced necrosis and apoptosis, as well as inhibits hydroquinone-induced production of reactive oxygen species (ROS), in human retinal pigment epithelial (RPE) cells.2 It decreases the expression of BAX, VEGFA, and ITB1 in human age-related macular degeneration (AMD) cybrid cell lines when used at a concentration of 20 mg/ml.3 Risuteganib arrests aberrant blood vessel growth mediated by αVβ3, αVβ5, and α5β1 integrins in vivo.1
