Antioxidant properties of ambroxol

Free Radical Biology and Medicine, 1994
We tested whether Ambroxol, a drug which stimulates the release of surfactant by pneumocytes type II, may also possess antioxidant properties. To assess the reactivity of Ambroxol with reactive oxygen species, we analysed its ability to decompose hydrogen peroxide (H2O2) and to inhibit the superoxide (O2.-)-dependent autooxidation of pyrogallol ...

Antioxidant properties of demethyldiisoeugenol

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1995
The antioxidant properties of demethyldiisoeugenol were investigated in this study using various models. Demethyldiisoeugenol inhibited Fe(2+)-induced lipid peroxidation in rat brain homogenate in a concentration-dependent manner with an IC50 1.8 +/- 0.1 microM.

Antioxidant properties of thiamine

Bulletin of Experimental Biology and Medicine, 2000
Thiamine (10(-4)-10(-6)M) inhibits lipid peroxidation in rat liver microsomes and free radical oxidation of oleic acid in vitro. Thiamine interacts with free radicals and hydroperoxides and is oxidized to thiochrome and thiamine disulfide. The antioxidant effect of thiamine is probably related to successive transfer of 2H(+)from the NH(2)group of the ...

Antioxidative Properties of Flavonoids

Current Organic Chemistry, 2011
Evidence accumulates that a family of plant compounds, known as flavonoids, can prevent or slow down the progression of cardiovascular diseases, cancer, inflammatory and neurodegenerative diseases. Flavonoids are considered beneficial, this is often attributed to their powerful antioxidant properties.

Antioxidant properties of aminoguanidine

Fundamental & Clinical Pharmacology, 1999
Abstract— It is well known that aminoguanidine (AG) can diminish advanced glycosylation of proteins, which might be beneficial in preventing chronic diabetic complications. Recent reports suggested an inter‐relationship between glycosylation of protein and free radical damage.

Antioxidant properties of argpyrimidine

European Journal of Pharmacology, 2008
Argpyrimidine, the product of non-enzymatic protein glycation by methylglyoxal, has been implicated in the pathophysiology of diabetes mellitus and neurodegenerative diseases. Chemically, argpyrimidine is a substituted pyrimidinol with structural features common to known antioxidants.

Antioxidant properties of steroids

The Journal of Steroid Biochemistry and Molecular Biology, 1993
To determine the relative ranking of antioxidative potential of various steroids the effect of 14 steroid compounds on the fluorescence of phycoerythrin was monitored over time following the addition of a peroxy radical generator 2,2'-azo-bis (2-amidino-propane) dihydrochloride.

Antioxidant Properties of Phytoestrogens

Journal of Medicinal Food, 1999
The oxidation of lipids is an autocatalytic process consisting of a number of well-defined interrelated chemical reactions. Its importance has long been recognized in the food and polymer industry, and recent advances in the understanding of vascular diseases have shown that lipid peroxidation also contributes to human disease.

Antioxidant Properties of Quercetin

2011
Quercetin, a plant-derived aglycone form of flavonoid glycosides, has been used as a nutritional supplement and may be beneficial against a variety of diseases, including cancer. We examined the antioxidant properties of quercetin. The reduction potential of quercetin was measured at various pH values using voltammetric methods, and its total ...
