The Thiol-Modifier Effects of Organoselenium Compounds and Their Cytoprotective Actions in Neuronal Cells [PDF]
Neurochemical Research, 2020 Most pharmacological studies concerning the beneficial effects of organoselenium compounds have focused on their ability to mimic glutathione peroxidase (GPx). However, mechanisms other than GPx-like activity might be involved on their biological effects.

Chemoprevention of cancer by organoselenium compounds
Journal of Cellular Biochemistry, 1995A major research goal of our laboratories is the development of new organoselenium cancer chemopreventive agents with less toxicity compared to some of the historical selenium compounds, such as sodium selenite. Ideally, such agents would be employed to inhibit tumor development in different organs caused by a variety of chemical carcinogens ...

Photochemistry of organoselenium compounds
Journal of the Chemical Society, Chemical Communications, 1974Irradiation of dibenzyl diselenide (l) with 350 nm light in the presence of oxygen afforded benzaldehyde and elemental selenium, whereas irradiation in the absence of oxygen produced dibenzyl monoselenide (ll); irradiation of dibenzyl triselenocarbonate (III) produced dibenzyl diselenide.

Crystal Structures of Organoselenium Compounds: Structural Descriptors for Chalcogen Bonds
Synthesis, 2022AbstractLess conventional non-covalent interactions such as chalcogen bonds attract the attention of researchers in various fields (organocatalysis, material sciences, biological chemistry, …). We present here useful descriptors to easily discriminate the structures in which chalcogen bonds involving selenium are observed.

Separation of organoselenium compounds and their electrochemical detection
Analytical and Bioanalytical Chemistry, 2004A simplified procedure based on ion-exchange separation of selenourea (Se-U) and selenocystamine (Se-CM), which have very close half-wave potential when they are simultaneously analyzed by voltammetric techniques, has been developed and optimized. Thus, selenocystamine remains in the cation exchanger Purolite C 100 H, whereas selenourea is found in the

Thermodynamics of organoselenium and organotellurium compounds
Russian Chemical Reviews, 1995Experimental values of the enthalpies of formation (ΔHf°) and of the specific heat (Cp°) of the organic compounds of selenium and tellurium, are discussed, including their complexes with dialkylzinc and dialkylcadmium. Different forms of the methods of combustion enthalpy and of reaction calorimetry, used to determine ΔHf° values, are examined.
