Scavenging Effects of Dexrazoxane on Free Radicals
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. However, it is not known whether the antiox...
متن کاملEffect of oxygen free radicals on Mg2+ efflux from erythrocytes.
Hydrogen peroxide destroyed the Na+/Mg2+ antiport in Mg(2+)-loaded human and rat erythrocytes and increased the leakage of intracellular Mg2+ and K+. These effects are opposite to the increase of Na+/Mg2+ antiport and unchanged Na(+)-independent Mg2+ efflux from erythrocytes of patients with cystic fibrosis score 3. Thus, the increase of Na+/Mg2+ antiport in these patients is not caused by incr...

متن کاملHPLC, NMR and MALDI-TOF MS analysis of condensed tannins from Lithocarpus glaber leaves with potent free radical scavenging activity.
Using acid-catalyzed degradation in the presence of cysteamine, the condensed tannins from Lithocarpus glaber leaves were characterized, following thiolysis, by means of reversed-phase HPLC, 13C-NMR and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) analyses. The thiolysis reaction products showed the presence of the procyanidin (PC) and prodelphinid...
متن کاملHESA-A Exerts Its Cytoprotective Effects through Scavenging of Free Radicals: An in Vitro Study
Background: Natural medicines have been recently considered more reasonable for human use most notably due to their safety and tolerance. HESA-A is a marine-originated herbal medicine with a variety of healing effects. However, its exact biological mechanism is not clear. The pre-sent study aimed at the evaluation of the HESA-A antioxidant effect. Methods: Chinese hamster ovary (CHO) an...
