When GSH reacts with DTNB, mixed disulfides (GS-S-DTNB) are formed, where the thiol group replaces one of the nitrobenzoic acid moieties in DTNB
This process, along with GCL inhibition and the formation of mixed disulfides between GSH and protein sulfhydryl, concurred to a steady-state decrement of free GSH concentration and, consequently, to an intracellular redox state shift toward more oxidizing conditions, which could be required for avoiding fast reduction of oxidized cysteines allowing the upstream ROS-induced autophagic stimulus to be propagated
