Oxidation, Nitrosation, and Nitration of Serotonin by Nitric Oxide-Derived Nitrogen Oxides: Biological Implications in the Rat Vascular System

Autor: Jean-François Gallard, Maryvonne Dendane, Chantal Houée-Levin, Claire Ducrocq, Abdelhak Karim, Didier Payen, Jean-Marie Launay, Beatrice Blanchard

Publikováno v: Nitric Oxide. 1:442-452

Because NO is not very reactive in an oxygen-free buffer, a significant part of serotonin (5-HT) is transformed by NO in nondeaerated phosphate buffer, at pH 7.4, into (4-serotonyl)-4-serotonin, 4-nitrososerotonin, and 4-nitroserotonin. Dimerization

Oxidation and Nitration of Catecholamines by Nitrogen Oxides Derived from Nitric Oxide

Autor: Claudine Servy, Maryvonne Dendane, Claire Ducrocq, Cyril Daveu, Philippe Marin

Publikováno v: Nitric Oxide. 1:234-243

The reactivity of catecholamines with nitrogen oxides formed from NO in aerated solutions, nitrite, and peroxynitrite was evaluated. Dopamine and norepinephrine in aerobic buffer (pH 7.4) were almost completely converted to their 6-nitro-derivatives

Nitration of angiotensin II by .NO2 radicals and peroxynitrite. .NO protects against .NO2 radical reaction

Autor: Claire Ducrocq, Maryvonne Dendane, Chantal Houé-Levin, Mare Cudic

Publikováno v: European journal of biochemistry. 265(3)

To react with peptides, nitric oxide.NO has to be activated by oxidation, or by coupling with superoxide (O.-2) thereby producing peroxynitrite. In the course of.NO oxidation,.NO2 free radicals and N2O3 may be formed. Using gamma-irradiation methods,

Chemical modifications of the vasoconstrictor peptide angiotensin II by nitrogen oxides (NO, HNO2, HOONO)--evaluation by mass spectrometry

Nitric oxide (NO) and angiotensin II are natural regulators of blood pressure. Under aerobic conditions, NO is transformed into its higher oxides (N2O4, NO2, NO/NO2 or N2O3) and oxoperoxonitrate (currently named peroxynitrite) by coupling with supero
