Mn(III)TMPyP is a manganese-porphyrin which acts as a superoxide dismutase (SOD) mimetic and peroxynitrite decomposition catalyst.1 SOD mimetics described to date are unstable and are capable of catalyzing undesired side-reactions in addition to the dismutation of the superoxide radical (O2-). Mn(III)TMPyP is an SOD mimetic with increased stability to pH and hydrogen peroxide. The rate constant for superoxide dismutation and peroxynitrite decomposition are 3.9 x 107 M−1s−1 and ~2 x 106 M−1s−1, respectively.1,2 Mn(III)TMPyP protected and enhanced the growth of SOD null E. coli with a doubling time of 60 minutes (as compared to 240 minutes of the control) at 25 µM.2
