Free Radical Scavenging Activity of Carnosine
Free Radical Research Communications, 1991The capacity of carnosine to decrease free radical-induced damage was evaluated using the oxidation of brain homogenates, the 2,2'-azobis-2-amidino propane-induced oxidation of erythrocyte ghost membranes, the radiation induced inactivation of horseradish peroxidase and the 2,2'-azobis-2-amidino propane-induced inactivation of lysozyme.

The anticonvulsant zonisamide scavenges free radicals
Epilepsy Research, 1998Zonisamide (ZNS) is effective in animal models of epilepsy and epileptic patients. The free radical scavenging activities of ZNS were analyzed by using electron spin resonance. ZNS, in the mmolar range, scavenged hydroxyl and nitric oxide radicals in a dose-dependent manner.

Silybin and 2,3-Dehydrosilybin Flavonolignans as Free Radical Scavengers.
Journal of Physical Chemistry B, 2015The electronic properties of six derivatives of silybin (characterized by the absence of the 2,3 double bond) and six derivatives of 2,3-dehydrosilybin (characterized by the presence of the 2,3 double bond) have been studied by applying density ...

Free radical‐scavenging properties of lignin
Nutrition and Cancer, 1998Lignin is one of the major components of dietary fiber. It is a complex hydrophobic molecule that typically occurs in cell walls with heteroxylans. Our experimental data show that lignin is a free radical scavenger. When the NADH-phenazine methosulfate-nitro blue tetrazolium free radical-producing system is used, an alkali-lignin concentration of 46.29

Copper or free radical scavenger?
Computational and Theoretical Chemistry, 2017Abstract Free radicals are very reactive molecules that produce so-called oxidative stress. To prevent oxidative stress there are two types of molecules: primary and secondary antioxidants. The chelation of copper is an example of a secondary antioxidant process. Therefore, these secondary antioxidants can be named copper scavengers. The main purpose

Carnitine as a free radical scavenger in aging
Experimental Gerontology, 2001Carnitine (4-N-trimethylammonium-3-hydroxybutyric acid) plays an important role in the translocation of acetyl moieties from the mitochondria into the cytoplasm for acetylcholine synthesis in the brain. Previous studies in our laboratory have shown that L-carnitine suppresses oxidative damage during aging.

Free Radicals and Their Scavengers in Parkinson’s Disease
European Neurology, 1993In recent years, it has been shown that active oxygen species or free radicals are closely involved in various diseases. Accumulating information supports the hypothesis that oxidative stress involving lipid peroxidation may contribute to the pathogenesis of Parkinson's disease.

Free Radical Scavenging Properties of Sulfinpyrazone
Free Radical Research, 2002Sulfinpyrazone, a potent uricosuric drug, was tested in vitro for its scavenging action against oxygen free radicals. In this study, sulfinpyrazone was able to scavenge 1,1-diphenyl-2-picrylhydrazyl radical with IC50 value of 29.82 micrograms/ml compared to butylated hydroxytoluene (BHT, IC50 value = 20.15 micrograms/ml) and Trolox (IC50 value = 16.01 ...

Allantoin as a free-radical scavenger.
Doklady. Biochemistry and biophysics, 2002In vertebrates, free purine bases are deaminated mainly to hypoxantine (Ia) or xantine (Ib), which are further oxidized to uric acid (Ic) in the presence of oxygen. Its further conversion (Ic to If) is shown in the following scheme:
