The FAD of the dnp-derivatized enzyme can still be reduced by NADPH (F) but is proposed to participate in two consecutive one-electron transfers to the nitro groups of the dnp moieties, producing nitro anion radicals (G, I) which may react with molecular oxygen to form superoxide (H, J)
Alternatively, inhibition of lipid peroxidation might also directly affect ferroptosis in either T [63] or B cells [64]
The treatment of GSH results in increased enzymatic activities such as SOD, CAT, GPX, GR, MDHAR, and DHAR, which leads to an increase in endogenous AsA and GSH levels, along with increased ratios of AsA/DHA and GSH/GSSG, thus reducing the level of overproduced ROS species (Jung et al., 2019
