An inducer of ferroptosis; induces ferroptosis, but not apoptosis or necroptosis, in NB1 cancer cells at 3 µM; inhibits proliferation of BJAB, NALM-6, Jurkat, MelHO, and MCF-7 cancer cells (IC50s = 0.07, 2.5, 1.5, 3 and 5 µM), as well as daunorubicine- and vincristine-resistant NALM-6 cells at 0.04-0.125 µM
