Background:
Cu-ATSP is a copper-containingbis(thiosemicarbazone) complex with ferroptosis inhibitory activity.1It traps peroxyl radicals in a cell-free assay when used at a concentration of 6 µM. Cu-ATSP inhibits ferroptosis induced by (1S,3R)-RSL3 in Pfa1 mouse embryonic fibroblasts (MEFs) and HT22 mouse hippocampal cells (EC50s = 8.5 and 16 nM, respectively). It increases intracellular copper levels but, unlike thebis(thiosemicarbazone) complexes Cu-CQ2 and CuNC2, does not reduce amyloid-β (1-40) (Aβ40) levels in CHO cells overexpressing amyloid precursor protein (APP).2
