WebApr 12, 2024 · Because GSH is only weakly cell membrane permeable, its biosynthesis is controlled by the intracellular cysteine concentration. Therefore, inhibitors of GSH biosynthesis can act as radio-sensitizers. Several reagents that directly interfere with GSH synthase have been evaluated in previous studies. WebIn the LPS-stimulated macrophages undergoing oxidative burst, intracellular storage of glutathione (GSH) is depleted, expression of iNOS is enhanced, and NO is overproduced. In response to the depletion of GSH, expression of HO-1 …

Herein, we report glutathione (GSH) reaction rates for N-phenyl acrylamides with varied substitutions at the α- and β-positions of the acrylamide moiety. We find that the GSH reaction rates can generally be …
WebHere, we review the rationale for, and recent advances in, pre-clinical and clinical research on antioxidant therapy in cancer, including targeting ROS with nonenzymatic antioxidants, such as NRF2 activators, vitamins, N-acetylcysteine and GSH esters, or targeting ROS with enzymatic antioxidants, such as NOX inhibitors and SOD mimics. WebRitonavir was more potent to stimulate GSH export from astrocytes than the antiretroviral protease inhibitors indinavir and nelfinavir, but combinations of ritonavir with indinavir or nelfinavir did not further stimulate astrocytic GSH export compared to a …
