Scheme 1

Proposed Mechanism for the MMn-Based Deactivation of Hemin- and Peroxynitrite (ONOO)-Mediated Oxidation and Nitration, as well as Oxidative Decomposition of Hydrogen Peroxide (H2O2)

Redox cycle of Mn(II/III) texaphyrin. Compounds I and II are generated by the reaction of hemin with H2O2. The Aβ peptide and axial ligands are omitted for clarity.
