WebMoreover, L-buthionine-sulfoximine (BSO), a GSH biosynthesis inhibitor, is incorporated into B-BiOCl NPs. The authors find that BSO can be released owing to the degradation of B-BiOCl NPs in the presence of acid and GSH, which are overexpressed in tumors. WebGlutathione (GSH) is the most abundant antioxidant in aerobic cells, present in micromolar (microM)-concentrations in bodily fluids and in millimolar (mM) concentrations in tissue. GSH is critical for protecting the brain from oxidative stress, acting as a free radical scavenger and inhibitor of lipid peroxidation. WebApr 10, 2024 · GPX4 can be most efficiently inhibited directly by RSL3. Moreover, GPX4 function can be impaired by targeting its usage of glutathione (GSH) as a substrate, either by erastin-mediated prevention of cystine uptake or by treatment with BSO, an inhibitor of the rate-limiting enzyme for de novo GSH synthesis. muchler financial services inc
