Oxidative Stress, Antioxidants, and Endothelial Function

Current Medicinal Chemistry, 2004
Endothelial dysfunction, characterized by a loss in nitric oxide bioactivity, is an early event in the development of atherosclerosis and determines future vascular complications. Emerging evidence suggests a causal role for oxidative stress in this process. Reactive oxygen species can directly inactivate nitric oxide, modulate protein function and act

Caroverine, a multifunctional drug with antioxidant functions

BioFactors, 2003
AbstractHere we show that lipid peroxidation of liposomal membranes was suppressed in the presence of Caroverine, a spasmolytic drug used in some countries. In order to understand the mechanism of this antioxidant action of Caroverine we studied the interaction of Caroverine with superoxide radicals, hydroxyl radicals and peroxynitrite.

Antioxidants, lipoprotein oxidation, and arterial function

Lipids, 1996
AbstractLipoproteins have an important influence on arterial tissues. High levels of low density lipoproteins (LDL) may inhibit arterial function in terms of the release of nitric oxide from the endothelium. This inhibition is enhanced by the oxidation of these lipoproteins which may occur during the development of atherosclerosis.

Vitamin E: beyond antioxidant function

The American Journal of Clinical Nutrition, 1995
Vitamin E, a potent peroxyl radical scavenger, is a chain-breaking antioxidant that prevents the propagation of free radical damage in biological membranes. We consider the evidence for potential sites in cellular metabolism and signal transduction where vitamin E may have a structure-specific role in addition to its antioxidant function.

Antioxidant function of vitamin A.

International journal for vitamin and nutrition research. Internationale Zeitschrift fur Vitamin- und Ernahrungsforschung. Journal international de vitaminologie et de nutrition, 1978
Feeding of 100 000 I.U. of Vitamin A on alternate days, five times to rats, resulted in a marked lowering in in vitro lipid peroxidation of the tissue hemogenates. alpha-Tocopherol or DPPD supplementation along with A still further reduced the in vitro lipid peroxidation of the tissues.

The suppression of granulocyte functions by lipophilic antioxidants

Biochemical Pharmacology, 1988
The effects of several antioxidants on the three major functions of human neutrophils--oxidative burst, secretion and leukotriene formation--were investigated with special emphasis on the lipophilicity. The most striking differences were obtained when ascorbate and the lipophilic ester ascorbyl palmitate were compared.

Modification of Muscle Protein Functionality by Antioxidants

1997
Protein oxidation is an important chemical process that occurs widely in biological systems. Recent advances in protein research have led to the recognition that muscle proteins, similar to nucleic acids and lipids, can be modified by oxygen free radicals.

Antioxidant Function of Thyroxinein Vivo

Endocrinology, 1968
The aim of this study has been to determine whether thyroxine may have an in vivo antioxidant effect. The possibility had been suggested from in vitro work. Euthyroid, male rats were treated with a single injection of 1 mg of L-thyroxine subcutaneously 24 hr prior to sacrifice.

Anticancer Antioxidant Regulatory Functions of Phytochemicals

Current Medicinal Chemistry, 2011
Plant foods are not only a main source of nutrients, but they are also rich in physiologically bioactive bionutrients or phytochemicals. Consumption of fruit and vegetables is associated with a decreased risk of pathological status, including cancer. Reactive oxygen species play a key role in the genesis and development of cancer.
