Efficient Scavenging of Fatty Acid Oxidation Products by Aminoguanidine
Chemical Research in Toxicology, 1997Lipid oxidation leads to the formation of reactive aldehydes that may play an important role in atherogenesis by altering the normal pathway of lipoprotein metabolism and by exerting toxic effects on vascular wall components. Recent studies indicate that advanced glycation end products, which form spontaneously from the reaction of reducing sugars with

Determination of peroxy radical-scavenging of lactic acid bacteria
International Journal of Food Microbiology, 2001Responses of lactic acid bacteria (LAB) to peroxy radicals generated via thermal (40 degrees C) decomposition of the diazocompound 2,2,-azo-bis (2-amidinopropane) dihydrochloride (ABAP), were studied. In general, LAB displayed survival curves with shoulders and tails indicative of 'multihit' killing by exposure to peroxy radicals.

Free Radical Scavenging by Myocardial Fatty Acid Binding Protein
Free Radical Research Communications, 1989Recent investigations have indicated the presence of a fatty acid binding protein (FABP) in mammalian heart. This protein binds free fatty acids and their esters with high affinity, however, its physiological role remains unknown. Since FABP constitutes a significant amount of cystolic protein, it is likely that it would be a target for free radical ...

Maleic acid modified cellulose for scavenging lead from water
International Journal of Biological Macromolecules, 2019Macro, micro and nano fibrillary cellulose with sodium maleate groups was synthesized by the reaction of cellulose with maleic anhydride followed by sodium exchange of protons. In the present work, we demonstrate that these carboxylic groups act as chemisorbants towards toxic heavy metal ions present in contaminated water.

Organic acids influence on DPPH scavenging by ascorbic acid
Food Chemistry, 2008The 2,2-diphenyl-1-picrylhydrazyl (DPPH·) test is largely used in plant or food biochemistry to evaluate the free radical scavenging effect of specific compounds or extracts. In its radical form, DPPH· has a broad absorption band in the visible region at 517 nm, while if it is protonated by an antiradical compound, it loses this property.

Hypochlorous Acid Scavenging Activities of Thioallyl Compounds from Garlic
Journal of Agricultural and Food Chemistry, 2010The hypochlorous acid (HOCl) scavenging capacities of 10 garlic compounds containing modifications in the thioallyl group (-S-CH2CH ═ CH2) were determined by a catalase protection assay, and the corresponding structure-activity relationships using molecular descriptors were calculated. This scavenging activity was enhanced by increasing the number of S

Ginsenoside Rb1 Directly Scavenges Hydroxyl Radical and Hypochlorous Acid
Current Pharmaceutical Design, 2012Reactive oxygen species (ROS) have been implicated in a variety of inflammatory diseases including cardiovascular disease (CVD), cancer, diabetes, Alzheimer's disease, autism, cataracts and aging. When endogenous mechanisms for the maintenance of redox homeostasis are overwhelmed, dietary intake of antioxidants contributes substantially to balancing ...

Synthetic Derivatives of Abietic Acid with Radical Scavenging Activity
Journal of Natural Products, 2001In this work, studies on the arylation of anilines derived from dehydroabietic acid, the main component of disproportionated rosin, are presented. The redox properties of the new diarylamines were investigated by cyclic voltammetry, and their free radical scavenging activity was tested by reduction of the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical ...

Lipoic acid, the oxidized form of 6,8-dimercapto-octanoic acid has a strained cyclic disulfide in a 1,2-dithiolane ring. Recently its antioxidant activity gained attention. Hypochlorous acid (HOCl) is an oxidant produced by neutrophils. A prominent effect of HOCl is the inactivation of alpha-1-antiproteinase.
