GSH maintains the antioxidant function of GPX4a central ferroptosis regulator that catalyzes GSH oxidation to oxidized glutathione (GSSG) while reducing cytotoxic lipid peroxides to non-toxic alcohols (L-OH), thereby mitigating oxidative damage ( blocks cystine import, disrupting GSH synthesis, impairing cellular antioxidant capacity, and inactivating GPX4, ultimately driving intracellular ROS accumulation and cell death
In terms of molecular mechanism, we also discussed the role of endogenous (enzymatic, and non-enzymatic) and exogenous antioxidants (vitamins, plant-derived and other small molecules), including ascorbic acids, -carotene, -tocopherol, -lipoic acid, coenzyme Q10, melatonin, and flavonoids (quercetin, luteolin, kaempferol, epicatechin, catechin, daidzein, genistein, and rutin, etc.) in scavenging of ROS
Pycnogenol is a plant extract from the bark of the French maritime pine tree, (also known as the Pinus pinaster tree) thats rich in antioxidants, particularly procyanidins
