Rats were born and raised in 60% O (2) for the first two postnatal weeks while treated with one of two antioxidants: vitamin E (via milk from mothers whose diet was enriched with 1000 IU vitamin E kg (-1)) or a superoxide dismutase mimetic, manganese (III) tetrakis (1-methyl-4-pyridyl) porphyrin pentachloride (MnTMPyP; via daily intraperitoneal injection of 5-10 mg kg (-1)); rats were subsequently raised in room air until studied as adults.

Furthermore, manganese superoxide dismutase (MnSOD) cDNA-transfected cells had decreased ROS.
ETC inhibitors (rotenone, 3-nitropropionic acid, thenoyltrifluoroacetone, antimycin A and sodium cyanide) were also tested to determine whether inhibitor treatment increased intracellular reactive oxygen species (ROS) generation.

Superoxide dismutase (SOD) and certain HO. and 1O2 scavengers were unable to exert significant effects.

With the spin trap 5,5-dimethyl-1-pyrroline-N-oxide (DMPO), prominent signals of O-2 adduct, DMPO-OOH, were detected from eNOS in the absence of added tetrahydrobiopterin (BH4), and these were quenched by superoxide dismutase.

In contrast to histatin 5, the conventional inhibitors of the respiratory chain, sodium cyanide or sodium azide, neither induced ROS nor killed yeast cells.
In addition, the membrane-permeant superoxide dismutase mimetic 2,2,6,6-tetramethylpiperidine-N-oxyl, abolished histatin-induced ROS formation in isolated mitochondria.

Catalase completely impaired this non-specific cytotoxicity (NSC), while superoxide dismutase (SOD) significantly enhanced it, suggesting a key role for hydrogen peroxide (H2O2) in the lysis of target cells.
Three heme-enzyme inhibitors, sodium azide, sodium cyanide and 3-amino-1,2,4-triazole, did not decrease NSC, but significantly enhanced it, suggesting that the mechanism involved is not dependent upon myeloperoxidase (MPO).

To mimic exercise-induced events such as energetic impairment, free radical generation, and lipid peroxidation in vitro, mouse-derived C2C12 myotubes were submitted to the inhibition of glycolytic and/or oxidative metabolism with 1 mM iodoacetate (IAA) and/or 2 mM sodium cyanide (CN), respectively, under 5% CO2/95% air up to 180 min.
By the addition of iron-chelating 1 mM deferoxamine to the C2C12 preparation with IAA + CN, both ESR signals of DMPO-OH and DMPO-R were completely abolished, and the release of MDA and LDH were significantly reduced, while cyanide-resistant manganese superoxide dismutase had negligible effects on these parameters.
