Peroxynitrous Acid Generated In Situ from Acidified H2O2 and NaNO2. A Suitable Novel Antimicrobial Agent? [PDF]

open access: goldAntibiotics, 2021
Peroxynitrite (ONOO−) and peroxynitrous acid (ONOOH) are known as short acting reactive species with nitrating and oxidative properties, which are associated with their antimicrobial effect.

Identification and quantification of protein nitration sites in human coronary artery smooth muscle cells in the absence and presence of peroxynitrous acid/peroxynitrite [PDF]

open access: goldRedox Biology, 2023
Peroxynitrous acid/peroxynitrite (ONOOH/ONOO−) is a powerful oxidizing/nitrating system formed at sites of inflammation, which can modify biological targets, and particularly proteins.

Peroxynitrous acid (ONOOH) modifies the structure of anastellin and influences its capacity to polymerize fibronectin [PDF]

open access: goldRedox Biology, 2020
Anastellin (AN), a fragment of the first type III module in fibronectin (FN), initiates formation of superfibronectin, a polymer which resembles the native cell-derived fibrillar FN found in the extracellular matrix of many tissues, but which displays ...

Oxidation of Aldehydes Used as Food Additives by Peroxynitrite [PDF]

open access: yesAntioxidants, 2023
Benzaldehyde and its derivatives are used as food supplements. These substances can be used mainly as flavorings or as antioxidants. Besides, peroxynitrite, an oxidizing agent, could be formed in canned food. Both species could react between them.

Peroxynitrous Acid ‐ Where is the Hydroxyl Radical? [PDF]

open access: bronzeIUBMB Life, 2003
AbstractPeroxynitrite is an inorganic toxin of physiological interest, formed from the diffusion‐controlled reaction of superoxide and nitrogen monoxide with a rate constant of (1.6 ± 0.3) × 1010 M ‐ 1 s ‐ 1. On the basis of three experiments we conclude that homolysis of the O‐O bond in peroxynitrous acid is unlikely: (1) the yield of nitrite from the

Mitochondria Play Essential Roles in Intracellular Protection against Oxidative Stress—Which Molecules among the ROS Generated in the Mitochondria Can Escape the Mitochondria and Contribute to Signal Activation in Cytosol? [PDF]

open access: yesBiomolecules
Questions about which reactive oxygen species (ROS) or reactive nitrogen species (RNS) can escape from the mitochondria and activate signals must be addressed.

Determination of nitrite in tap waters based on fluorosurfactant-capped gold nanoparticles-enhanced chemiluminescence from carbonate and peroxynitrous acid [PDF]

open access: greenIn Analysis, 2011
Fluorosurfactant (FSN)-capped gold nanoparticles (GNPs), which exhibit higher stability at a wider pH range and high ionic strength, were utilized for investigating the chemiluminescence (CL) effect on the reaction between high concentration carbonate ...
