In-Vitro Antioxidant Activity of Avocado Fruit Oil in Erbil, Kurdistan Region

open access: yesEurasian Journal of Science and Engineering, 2022
Many human diseases are linked to the accumulation of free radicals. Antioxidants can scavenge free radicals, lessening their impact. As a result, searching for naturally occurring antioxidants in plants is critical.

Scavenging Effects of Dexrazoxane on Free Radicals [PDF]

open access: yesJournal of Clinical Biochemistry and Nutrition, 2010
Dexrazoxane (ICRF-187) has been clinically used to reduce doxorubicin-induced cardiotoxicity for more than 20 years. It has been proposed that dexrazoxane may act through its rings-opened hydrolysis product ADR-925, which can either remove iron from the iron-doxorubicin complex or bind to free iron, thus preventing iron-based oxygen radical formation ...

Electrochemical Interaction Between Free Radicals and Lappaconitines

open access: yesInternational Journal of Electrochemical Science, 2018
We used electrochemical analysis methods to study how the aconitum alkaloids lappaconitine and its salts (HBr-lappaconitine, HCl-lappaconitine) scavenge free radicals (superoxide anion radical, 2,2-diphenyl-l-picrylhydrazyl, hydroxyl radical and lipid ...

Free Radical Scavenging Potency of Dihydroxybenzoic Acids

open access: yesJournal of Chemistry, 2017
In order to evaluate the free radical scavenging potency of dihydroxybenzoic acids (DHBAs) the Density Functional Theory (DFT) was used. The M05-2X/6-311++G(d,p) and B3LYP-D2/6-311++G(d,p) theoretical models were applied.
