GPX4 Inhibitor 26a

GPX4 inhibitor 26a is an inhibitor of glutathione peroxidase 4 (GPX4). It inhibits GPX4 activity by 71.7% at 1 µM. GPX4 inhibitor 26a is cytotoxic to 4T1 and MCF-7 breast cancer cells and HT-1080 fibrosarcoma cells (IC50s = 0.78, 6.9, and 0.15 µM, respectively). It decreases intracellular glutathione (GSH) levels and induces lipid peroxidation and ferroptosis in 4T1 cells when used at a concentration of 5 µM. GPX4 inhibitor 26a (15 and 30 mg/kg) reduces tumor growth in a 4T1 mouse xenograft model.Formal Name: alpha-[(2-chloroacetyl)[4-(5-oxazolyl)phenyl]amino]-N-(2-phenylethyl)-benzo[b]thiophene-3-acetamide.
