Polyphenols and Red Wine as Antioxidants against Peroxynitrite and other Oxidants
(Sociedad de Biología de Chile, 2004)
Oxidation and nitration of ribonuclease and lysozyme by peroxynitrite and myeloperoxidase
(ELSEVIER SCIENCE INC, 2009)
In spite of the many studies on protein modifications by reactive species, knowledge about the products resulting from the oxidation of protein-aromatic residues, including protein-derived radicals and their stable products, ...
Thiol oxidation by nitrosative stress: Cellular localization in human spermatozoa
(Informa Healthcare, 2016-09)
Peroxynitrite is a highly reactive nitrogen species and when it is generated at high levels it causes nitrosative stress, an important cause of impaired sperm function. High levels of peroxynitrite have been shown to ...
LEISHMANICIDAL ACTIVITY OF PEROXYNITRITE
(Churchill Livingstone Inc Medical PublishersNew York, 1995)
Mechanism of cysteine oxidation by peroxynitrite: an integrated experimental and theoretical study
Since peroxynitrite was identified as a pathophysiological agent it has been implicated in a great variety of cellular processes. Particularly, peroxynitrite mediated oxidation of cellular thiol-containing compounds such ...
Regulation of matrix metalloproteinases 2 and 9 activities by peroxynitrites in term placentas from type 2 diabetic patients
(Sage Publications, 2012-08)
Matrix metalloproteinases (MMPs) are proteolytic enzymes related to a proinflammatory environment in several diseases, including diabetes, which can be activated by reactive nitrogen species. This work aimed to determine ...
Insights into the mechanism of the reaction between hydrogen sulfide and peroxynitrite
(Elsevier Science Inc, 2015-01)
Hydrogen sulfide and peroxynitrite are endogenously generated molecules that participate in biologically relevant pathways. A revision of the kinetic features of the reaction between peroxynitrite and hydrogen sulfide ...
Peroxynitrite affects Ca2+ transport in Trypanosoma cruzi
(Elsevier Science BvAmsterdamHolanda, 1999)
Radical acetylation of 2`-deoxyguanosine and L-histidine coupled to the reaction of diacetyl with peroxynitrite in aerated medium
(AMER CHEMICAL SOC, 2008)
Diacetyl, like other alpha-dicarbonyl compounds, is reportedly cytotoxic and genotoxic. A food and cigarette contaminant, it is related with alcohol hepatotoxicity and lung disease. Peroxynitrite is a potent oxidant formed ...
Role of peroxynitrite in macrophage microbicidal mechanisms in vivo revealed by protein nitration and hydroxylation
(Pergamon-elsevier Science LtdOxfordInglaterra, 2001)
