15-LOX-1 inhibitor 2 (Compound 5i) is a potent inhibitor of 15-lipoxygenase-1 (15-LOX-1), with an IC50 of 1.7 μM. By inhibiting the activity of the 15-LOX-1 enzyme, it reduces the production of lipid peroxides, thereby preventing lipid peroxidation and protecting cells from RSL3-induced cell death. This compound is valuable for research into cell death mechanisms and oxidative stress-related conditions.
