Electrochemistry and Reactivity against Superoxide Anion Radicals of Hydroxycoumarins and Its Derivatives
(IOP Publishing Ltd, 2020-12-10)
The present studies reveal superoxide radical anion reactivity against synthesized coumarins. Free radicals play an important role in many diseases and they have a protective function also. Therefore, we must keep a balance ...
NEUTROPHILS AND MONONUCLEAR-CELLS FROM PATIENTS WITH CHRONIC GRANULOMATOUS-DISEASE RELEASE NITRIC-OXIDE
(Blackwell Science LtdOxfordInglaterra, 1993)
(−)-Epicatechin prevents alterations in the metabolism of superoxide anion and nitric oxide in the hearts of L-NAME-treated rats
(Royal Society of Chemistry, 2014-10)
The aim of this work was to evaluate the effects of (−)-epicatechin administration in the heart of a rat model with reduced NO production that follows a short-term treatment with L-NAME. Sprague-Dawley rats were treated ...
Pyrogallol red oxidation induced by superoxide radicals: Application to evaluate redox cycling of nitro compounds
(2011)
The bleaching of the pyrogallol red (PGR) dye mediated by superoxide anion radicals (O2-) generated from the xanthine/xanthine oxidase system (X/XO) was studied by UV-visible spectrophotometry. The absorption band (at 540 ...
Cadmium modulates NADPH oxidase activity and expression in sunflower leaves
(Springer, 2012-06)
The production of reactive oxygen species (ROS) and the ways by which ROS are generated are very important facts related to heavy metal toxicity in plants. In this work, superoxide anion (O2·-) generation diminished in ...
Free radical scavenging profile and myeloperoxidase inhibition of extracts from antidiabetic plants: Bauhinia forficata and Cissus sicyoides
(Soc Biolgia Chile, 2008-01-01)
There is abundant evidence that reactive oxygen species are implicated in several physiological and pathological processes. To protect biological targets from oxidative damage. antioxidants must react with radicals and ...

Oxidation of Hantzsch 1,4-dihydropyridines of pharmacological significance by electrogenerated superoxide
(KLUWER ACADEMIC/PLENUM PUBL, 2004-03)
The final pyridine derivatives were separated and identified by gas chromatography/ mass spectrometry (GC-MS). The intermediates, anion dihydropyridine and the HO2./HO2- species, were observed from voltammetric studies and ...
Larrea divaricata Cav (Jarilla): Production of superoxide anion, hydrogen peroxide and expression of zymosan receptors
(Taylor & Francis, 2008-09)
Larrea divaricata is a plant widely used in folk medicine in Argentina. This work aimed to study the mechanisms of decoction activity on the release of oxygen reactive species. Decoction increased the binding of zymosan-FITC ...
Formation of cytotoxic intermediates in the course of photodecomposition of a nitroheterocyclic antiseptic quinifuryl
(Elsevier Science SaLausanneSuíça, 2006)
