Free radicals have been implicated in the pathogenesis of diseases such as ischemia, arteriosclerosis, diabetes, rheumatoid arthritis, inflammation and the initiation of cancer.1–3 There is considerable evidence that antioxidants may help prevent illnesses caused by oxidative stress due to their capacity to quench free radicals, thereby protecting cells and tissues from oxidative damage. Thus, the demand for alternative antioxidants from natural sources is gradually growing. The genus Sargassum…

Antioxidant and antiviral activities of plastoquinones from the brown alga Sargassum micracanthum, and a new chromene derivative converted from the plastoquinones.
TLDR
One of the plastoquinones and the chromene exhibited significant antioxidant activities, such as an inhibitory effect on lipid peroxidation and a radical scavenging effect on 1,1-diphenyl-2-picrylhydrazyl (DPPH).
Inhibitory activities of plastoquinones and chromene derivative from a brown alga Sagassum micracanthum on bone resorption.
TLDR
The results suggest that the inhibitory effects of the three compounds on the differentiation, pit formation and the survival of OCLs might contribute to the suppression of bone resorption.
Antioxidant therapy: a new pharmacological approach in shock, inflammation, and ischemia/reperfusion injury.
TLDR
Treatment with either peroxynitrite decomposition catalysts and selective superoxide dismutase mimetics, or with SODm, have been shown to prevent in vivo the delayed vascular decompensation and the cellular energetic failure associated with shock, inflammation, and ischemia/reperfusion injury.
Antioxidants in the treatment of diabetes.
TLDR
There is not any established benefit for antioxidants use in the management of diabetic complications, therefore, routine vitamin or mineral supplementation is not generally recommended.
