glutathione peroxidase v. the kinetic mechanism Selenoprotein 4: From Molecular Mechanisms to Novel Therapeutic Opportunities Kinetic Study of the Reaction

Although these classical inhibitors show great potential in preclinical research, their clinical translation still faces substantial obstacles, including poor metabolic stability, suboptimal pharmacokinetics, and the critical fact that no anti-ferroptosis drug has yet entered human trials

At physiological pH, peroxynitrite will comprise a mixture of ONOO and the protonated peroxynitrous acid (ONOOH)

Together, these findings indicate that while strong oxidants, such as H 2 O 2 , favor irreversible thiol overoxidation and suppress disulfide chemistry, reactive nitrogen species provide a physiologically relevant pathway for disulphide cross-linking of TTR
