Synthetic organoselenium compounds as antioxidants:glutathione peroxidase activity
TL;DR: This review deals with the use of various synthetic organoselenium compounds as mimics of glutathione peroxidase (GPx), a selenoenzyme which catalyses the reduction of a variety of hydroperoxides and protects the cell membranes from oxidative damage.
Journal ArticleDOI
Organoselenium chemistry: role of intramolecular interactions.
TL;DR: The subject of hypervalency has not attracted much attention and is the focus of this review of selenium chemistry, which has now become a well-established field of research.
Journal ArticleDOI
Glutathione peroxidase-like antioxidant activity of diaryl diselenides: a mechanistic study.
TL;DR: The synthesis, structure, and thiol peroxidase-like antioxidant activities of several diaryl diselenides having intramolecularly coordinating amino groups are described and the mechanistic role of various organoselenium intermediates is investigated.
Journal ArticleDOI
Heteroatom-directed aromatic lithiation: a versatile route to the synthesis of organochalcogen (Se, Te) compounds.
TL;DR: The differences in the stability and reactivity of the organochalcogen compounds derived from various substrates are described in terms of electronic and stereochemical properties of donor atoms.
Journal ArticleDOI

TL;DR: Comparison between diselenide 15 and ditelluride 22 using the extent of orbital interaction as well as the value of electron density at the bond critical points unequivocally established that a diteLLuride could be a better acceptor in nonbonding interaction, when the hydroxy group acts as the donor.
