Mn(III)TMPyP is a manganese-porphyrin which acts as a superoxide dismutase (SOD) mimetic and peroxynitrite decomposition catalyst. 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. Mn(III)TMPyP protected and enhanced the growth of SOD E. coli with a doubling time of 60 minutes (as compared to 240 minutes of the control) at 25 µM.

9(E),11(E)-12-nitro Conjugated linoleic acid (9(E),11(E)-12-nitro CLA) is a nitrated fatty acid. It is formed from 9(Z),11(E)-CLA upon exposure to acidified nitrite, peroxynitrite, gaseous nitrogen dioxide, or a combination of myeloperoxidase, hydrogen peroxide, and nitrite.1It is also formed in LPS-stimulated RAW 264.7 macrophages, an effect that can be reduced by the nitric oxide synthase (NOS) inhibitor L-NAME .29(E),11(E)-12-nitro CLA has been found in human plasma.

Coumarin boronic acid (CBA) is a fluorescent probe that can be used to detect peroxynitrite , hypochlorous acid, and hydrogen peroxide.It reacts with peroxynitrite at an exponentially faster rate (k = 1.1 μM/s) than hydrogen peroxide (k =1.5 M/s) and moderately faster rate than hypochlorous acid. Peroxynitrite oxidizes CBA into the fluorescent product 7-hydroxycoumarin (COH), which displays excitation/emission maxima of 332/470 nm, respectively.
Coumarin boronic acid pinacolate ester (CBE) is a more soluble form of coumarin boronic acid that can be used to detect peroxynitrite , hypochlorous acid, and hydrogen peroxide. Peroxynitrite oxidizes CBE into the fluorescent product 7-hydroxycoumarin (COH), which displays excitation/emission maxima of 332/470 nm, respectively.
9(E),11(E)-9-nitro Conjugated Linoleic Acid (9E,11E-9-nitro CLA) is a nitrated fatty acid produced from 9Z,11E-CLA through exposure to acidified nitrite, peroxynitrite, gaseous nitrogen dioxide, or the combined action of myeloperoxidase, hydrogen peroxide, and nitrite. Additionally, it forms in LPS-stimulated RAW 264.7 macrophages, a process that can be inhibited by the nitric oxide synthase (NOS) inhibitor L-NAME. This compound has also been detected in human plasma.
