Diphenyl diselenide a janus-faced molecule [PDF]

open access: yesJournal of the Brazilian Chemical Society, 2010
In this review, we summarized the potential role of synthetic organoseleno compounds as therapeutic or toxic agents, giving emphasis almost exclusively to diphenyl diselenide, the simplest of the diaryl diselenides, and some of its analogs. We presented the main molecular aspects related to the in vitro toxicity and pharmacology of diphenyl diselenide ...

Carbocyclization by Radical Closure onto O-Trityl Oximes:  Dramatic Effect of Diphenyl Diselenide

open access: yes, 2016
O-Trityl oximes of 5- and 6-iodoaldehydes undergo radical cyclization to produce oximes when treated in refluxing tetrahydrofuran (THF) with Bu3SnH, 1,1‘-azobis(cyclohexanecarbonitrile), i-Pr2NEt, and diphenyl diselenide (PhSeSePh)

Cesium Carbonate-Catalyzed α-Phenylchalcogenation of Carbonyl Compounds with Diphenyl Dichalcogenide

open access: yesMolecules, 2009
It was found that cesium carbonate has a unique catalytic ability on the reaction of carbonyl compounds with diphenyl diselenide to give the corresponding α-phenylseleno carbonyl compounds in moderate to good yields.

Selenium-Catalyzed Reduction of Hydroperoxides in Chemistry and Biology

open access: yesAntioxidants, 2021
Among the chalcogens, selenium is the key element for catalyzed H2O2 reduction. In organic synthesis, catalytic amounts of organo mono- and di-selenides are largely used in different classes of oxidations, in which H2O2 alone is poorly efficient ...

Catalytic Antioxidant Activity of Bis-Aniline-Derived Diselenides as GPx Mimics

open access: yesMolecules, 2021
Herein, we describe a simple and efficient route to access aniline-derived diselenides and evaluate their antioxidant/GPx-mimetic properties. The diselenides were obtained in good yields via ipso-substitution/reduction from the readily available 2 ...

A Simple Zinc-Mediated Method for Selenium Addition to Michael Acceptors

open access: yesMolecules, 2020
In this work, we focused our attention on seleno-Michael type reactions. These were performed using zinc-selenolates generated in situ from diphenyl diselenide 1, 1,2-bis(3-phenylpropyl)diselenide 30, and protected selenocystine 31 via an efficient ...

New therapeutic approach: diphenyl diselenide reduces mitochondrial dysfunction in acetaminophen-induced acute liver failure. [PDF]

open access: yesPLoS ONE, 2013
The acute liver failure (ALF) induced by acetaminophen (APAP) is closely related to oxidative damage and depletion of hepatic glutathione, consequently changes in cell energy metabolism and mitochondrial dysfunction have been observed after APAP overdose.

Promoting the sulfur redox kinetics by mixed organodiselenides in high-energy-density lithium–sulfur batteries

open access: yeseScience, 2021
Lithium–sulfur (Li–S) batteries are considered as a highly promising energy storage system due to their ultrahigh theoretical energy density. However, the sluggish kinetics of the complex multi-electron sulfur redox reactions seriously hinders the actual

Over-activation of the Drosophila melanogaster hsp83 gene by selenium intoxication

open access: yesGenetics and Molecular Biology, 2008
Selenium is an important dietary micronutrient and an essential component of selenoproteins and the active sites of some enzymes, although at high concentrations it is toxic.

Diphenyl diselenide supplemented diet reduces depressive-like behavior in hypothyroid female rats [PDF]

open access: yes, 2014
Hypothyroidism has been associated to psychiatric disorder development and tissue oxidative damage. In this study, we evaluated the effect of diphenyl diselenide supplementation on depressive-like behavior triggered by methimazole exposure in female rats.
