Uses
RC574 is a novel probucol analog with the activity to protect mouse hippocampal cells and primary cortical neurons from glutamate-induced oxidative cell death (ferroptosis) and increase glutathione peroxidase (GPx) 1 levels and activity.
Biological Activity
RC574 is an inhibitor of ferroptosis and a derivative of the antioxidant and hypocholesterolemic agent probucol .1 It inhibits glutamate-induced cell death in HT22 cells (IC50 = 276.2 nM) and mouse primary cortical neurons when used at a concentration of 3 μM. RC574 (3 μM) increases glutathione peroxidase 1 (GPX1) levels and GPX activity, as well as inhibits glutamate-induced mitochondrial superoxide anion production, in HT22 cells. It completely inhibits ferroptosis induced by the GPX4 inhibitor RSL3 in HT22 cells when used at concentrations ranging from 62.5 to 1,000 nM.
