    Product Description

    Imidazole ketone erastin is an inducer of ferroptosis.1 It inhibits glutamate release in human CCF-STTG1 astrocytoma cells (IC50 = 30 nM), indicating inhibition of the system xc- cystine/glutamate transporter.2 Imidazole ketone erastin increases production of lipid reactive oxygen species (ROS) in SUDHL6 diffuse large B cell lymphoma (DLBCL) cells in a concentration-dependent manner, as well as reduces glutathione (GSH) levels in these cells (IC50 = 34 nM).1 It inhibits the growth of HT-1080 fibrosarcoma cells (GI50 = 310 nM) as well as HRASG12V-overexpressing BJeLR cells (IC50 = 3 nM).2 Imidazole ketone erastin (23 and 40 mg/kg) reduces tumor growth in an SUDHL6 mouse xenograft model.1
