A primary-alkyl-substituted selenenyl iodide was successfully synthesized through oxidative iodination of a selenol with N-iodosuccinimide by taking advantage of a cavity-shaped steric protection group. The selenenyl iodide exhibited high thermal sta

Sulfenylation (RSH → RSOH) is a post-translational protein modification associated with cellular mechanisms for signal transduction and the regulation of reactive oxygen species. Protein sulfenic acids are challenging to identify and study due to t

A stable primary-alkyl-substituted selenenic acid was developed as a synthetic model of selenocysteine–derived selenenic acid (Sec–SeOH) by taking advantage of a huge cavity-shaped substituent. The primary-alkyl model compound was successfully ap

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. Bio

Chalcogen-nitrogen chemistry deals with systems in which sulfur, selenium, or tellurium is linked to a nitrogen nucleus. This chemical motif is a key component of different functional structures, ranging from inorganic materials and polymers, to rati

DFT calculations performed on amidoaryldiselenides as electrophilic derivatives evidenced the presence of a prevalent Se⋯O weak interaction when selenium is bonded to a Se atom (diselenides), a Br atom (selenenyl bromide) and an O atom (selenenic a

Glutathione peroxidases (GPX) are anti-oxidative enzymes that reduce organic and inorganic hydroperoxides to the corresponding alcohols at the expense of reduced glutathione. The human genome involves eight GPX genes and five of them encode for selen

The mechanism of action of the selenenamide 1 as a mimic of the glutathione peroxidase (GPx) was investigated by the density functional theory. The solvent-assisted proton exchange procedure was applied to model the catalytic behavior and antioxidant

The unprecedented dehydration of a selenenic acid (RCH2SeOH) to a selenoaldehyde (RCH=Se) has been demonstrated. A primary-alkyl-substituted selenenic acid was synthesized for the first time by taking advantage of a bulky cavity-shaped substituent. U

Selenenic acids are highly reactive intermediates of selenoproteins’ enzymatic reactions. Knowledge of how the protein environment protects and stabilizes them is fundamental not only to descriptions of selenoproteins’ reactivity but also potenti
