Real-time single-cell imaging reveals accelerating lipid peroxyl radical formation in Escherichia coli triggered by a fluoroquinolone antibiotic
(American Chemical Society, 2020-07)
Formation of reactive oxygen species (ROS) induced by bactericidal antibiotics has been associated with a common, non-specific, mechanism of cellular death. Herein we report real-time single cell fluorescence studies on ...
Antioxidant activity of gadusol and occurrence in fish roes from Argentine Sea
(Elsevier, 2010-03-15)
The occurrence of the natural antioxidant gadusol (3,5,6-trihydroxy-5-hydroxymethyl-2-methoxycyclohex-2-en-1-one) was quantified in fish roes of three species from Argentine Sea: argentine hake (Merluccius hubbsi), brazilian ...
Tyrosine oxidation and nitration in transmembrane peptides is connected to lipid peroxidation
(Elsevier Science Inc, 2017-05)
Tyrosine nitration is an oxidative post-translational modification that can occur in proteins associated to hydrophobic bio-structures such as membranes and lipoproteins. In this work, we have studied tyrosine nitration ...
Free radical scavenging capacity and antioxidant activity of cochineal (Dactylopius coccus C.) extracts
(Elsevier, 2010-03)
Carminic acid (CA) is a natural red pigment produced by Dactylopius coccus C. insects. It is widely used in the food industry to replace synthetic colourants. Despite being known for a long time, its antioxidant properties ...
Free radical scavenging activities and inhibition of inflammatory enzymes of phenolics isolated from Tripodanthus acutifolius
(Elsevier Ireland, 2010-07)
Ethnopharmacological relevance: Leaf extracts from Tripodanthus acutifolius (Ruiz and Pavón) Van Tieghem have long been used in argentinean traditional medicine as anti-inflammatory, however, there is no scientific evidence ...
Regulation of lipid peroxidation and ferroptosis in diverse species
(Cold Spring Harbor Laboratory Press, 2018-05)
Lipid peroxidation is the process by which oxygen combines with lipids to generate lipid hydroperoxides via intermediate formation of peroxyl radicals. Vitamin E and coenzyme Q10 react with peroxyl radicals to yield ...
Biological activities of Zn(II)- S -methyl-cysteine complex as antiradical, inhibitor of acid phosphatase enzyme and in vivo antidepressant effects
(Taylor & Francis, 2016-03)
The antidepressant effect of simple Zn(II) salts has been proved in several animal models of depression. In this study, a coordination metal complex of Zn(II) having a sulfur containing ligand is tested as antidepressant ...
Antioxidant and anticancer effects and bioavailability studies of the flavonoid baicalin and its oxidovanadium(IV) complex
(Elsevier Science Inc, 2017-01)
Based on the known antioxidant effect of flavonoids, baicalin (baic) found in roots of Scutellaria has been selected. Its coordination complex with the oxidovanadium(IV) cation, Na4[VO(baic)2].6H2O (VIVO(baic)), was ...
Vitamin A palmitate and α-lipoic acid stability in o/w emulsions for cosmetic application
(Society Of Cosmetic Chemists, 2011-07)
Skin becomes thin, dry, pale, and fi nely wrinkled with age. Retinoids are a large class of compounds that are important in modern therapy for dermatological treatment of wrinkled skin. Of the retinoids, retinol and vitamin ...
Atypical antioxidant activity of non-phenolic amino-coumarins
(Royal Society of Chemistry, 2018-01)
Coumarin compounds have been described as anti-inflammatories, and chemotherapeutic agents as well as antioxidants. However, the origin of the antioxidant activity of non phenolic coumarins remains obscure. In the present ...
