Role of Organotellurium Species in Tellurium Neuropathy
Neurochemical Research, 1998Exposure of weanling rats to a diet containing 1% elemental tellurium causes segmental demyelination of peripheral nerve, and an inhibition of squalene epoxidase. This inhibition is thought to be the mechanism of action leading to demyelination. Tellurite appears to be the active inhibitory species in a cell-free system but the active species in vivo ...

Generation of an Organotellurium(II) Cation
European Journal of Inorganic Chemistry, 2012AbstractWe expected that the chemical trapping products of low‐coordinated tellurenyl cation species can also be kinetically stabilized by the Tbt or Bbt group. Recently, we have reported the halogenation reactions of Bbt‐substituted ditelluride, BbtTeTeBbt, leading to the formation of the TeII–TeIV mixed‐valent tellurenyl fluoride, BbtTeTe(F)2Bbt, and

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.

Organotellurium derivatives of dicarboxylic acids
Journal of Organometallic Chemistry, 1976Abstract The freshly prepared sodium salts of ortho-phthalic acid and tetrabromo ortho-phthalic acid react with diaryltellurium dichlorides in chloroform to afford new dimeric organotellurium carboxylates, R2Te(C8X4O4)2 (X = H, Br). The new compounds contain fourteen membered rings and the detailed structure is discussed particularly in the light of ...

Antioxidative properties of organotellurium compounds in cell systems
Biochemical Pharmacology, 1998The protective/antioxidative properties of diaryl tellurides were demonstrated in cellular systems of increasing complexity. In the presence of glutathione, bis(4-hydroxyphenyl) telluride (1a), bis(4-aminophenyl) telluride (1d) and bis(2-carboxyphenyl) telluride (1h) reduced by more than 50% t-butyl hydroperoxide-induced cell death in lung fibroblast ...

ANTIBACTERIAL PROPERTIES OF ORGANOTELLURIUM COMPOUNDS
Problems of Biological, Medical and Pharmaceutical ChemistryIntroduction. Antimicrobial resistance in bacteria has become a global challenge for public health systems. Bacteria that pose the greatest threat to human health due to their increasing resistance to antibiotics include Escherichia coli, Staphylococcus aureus and Salmonella spp. The purpose of the work is to study the antibacterial properties of three

Organotellurium compounds as stabilizers for polymeric materials
Journal of Applied Polymer Science, 1996The thermal stability of a series of organotellurium compounds was determined by thermogravimetric analysis and the stabilizing capacity of the most heat-resistant compounds assessed in natural rubber, polyethylene, and polypropylene by measurement of ...
