Ferroptosis inducer-9 is a ferroptosis inducer and colchicine site tubulin polymerization inhibitor. Ferroptosis inducer-9 inhibits MCF-7 cell growth with an IC50 of 14 nM and inhibits [3H]colchicine binding. Ferroptosis inducer-9 reduces expression of GPX4 and FTH, increases COX2 and ACSL4, lowers GSH, NADP+, and NADPH levels, increases LPO, MDA, and Fe(II) levels, and decreases SOD concentrations. Ferroptosis inducer-9 demonstrates significant anti-tumor efficacy in HCT116 CRC xenograft model. Ferroptosis inducer-9 can be used for the study of triple negative breast cancer (TNBC) and colorectal cancer (CRC)[1].
