Membranes as Structural Antioxidants

Imidazolopyrazinones as potential antioxidants.

A series of imidazolopyrazinones 3, substituted at C-2, and C-2/C-6, has been prepared. The compounds behaved as quenchers of superoxide anion. The more active compounds are structurally related to coelenterazine, a natural substrate of marine bioluminescence. Theoretical parameters based on Hartree-Fock instabilities have been examined.

Flaxseed phenolics as natural antioxidants

Flaxseed is a rich source of different types of phenolics such as lignans, phenolic acids, flavonoids, phenylpropanoids and tannins. To date, extensive investigations has been undertaken to demonstrate antioxidant potential of flaxseed phenolics. However, antioxidant potential of all the flaxseed phenolics has not been collectively discussed. Hence, the aim of this article is to highlight the v...

Coral Fluorescent Proteins as Antioxidants

BACKGROUND A wide array of fluorescent proteins (FP) is present in anthozoans, although their biochemical characteristics and function in host tissue remain to be determined. Upregulation of FP's frequently occurs in injured or compromised coral tissue, suggesting a potential role of coral FPs in host stress responses. METHODOLOGY/PRINCIPAL FINDINGS The presence of FPs was determined and quan...
