Toxicity of selenium compounds to alveolar macrophages

Toxicology Letters, 1981
Selenium compounds released into urban atmospheres as a result of fossil fuel combustion may pose an inhalation hazard to people. Two chemical forms of selenium produced during coal combustion and present in combustion effluent are selenious acid. H2SeO3, and elemental selenium, Se. In an attempt to determine the toxicity of selenium compounds relative

Interaction kinetics of selenium-containing compounds with oxidants

Free Radical Biology and Medicine, 2020
Selenium compounds have been identified as potential oxidant scavengers for biological applications due to the nucleophilicity of Se, and the ease of oxidation of the selenium centre. Previous studies have reported apparent second order rate constants for a number of oxidants (e.g.

Organogallium-Selenium Compounds

1986
Ga(CH3)2SeCH3 is obtained as a nonvolatile solid by condensation of Ga(CH3)3 on CH3SeH (1:1 mole ratio). The dimeric product melts at 119 to 120°C. The vapor pressure has been determined in the 120 to 140°C range to give the equation log (p/Torr) = 9.63–3450/T and ?HV=16 kcal/mol. The compound is dimeric in the vapor phase.

Pharmacology of synthetic organic selenium compounds

1991
The similarity in the chemical properties of sulfur and selenium has tempted medical chemists for many years to prepare, for comparative purposes, a wide variety of selenium derivatives of sulphur- or oxygen-containing compounds. Because of the widespread use of this chemical comparison, the list of published and/or patented structures of organic ...

Organoindium-Selenium Compounds

1991
This compound formed when In(C2H5)3 was allowed to react with HSeSi(C2H5)3 (1:1 mole ratio) in hexane at 0 °C, evolving C2H6. After removing the solvent, the residual liquid was distilled (b.p. not reported); m.p. −55 to −54 °C, 17.5% yield. The compound is dimeric in benzene (cryoscopic measurement) and was postulated to have the structure of the ...

Compounds of Thorium and Selenium

1985
The binary compounds ThSe, Th2Se3, Th7Se12, ThSe2, Th2Se5, and ThSe3 are reported to exist in the thorium-selenium system, based on X-ray diffraction measurements and chemical analysis. A further compound, ThSe2.33 (or Th3Se7), prepared by the reaction of the elements, could not be confirmed crystallographically [1].

[Selenium compounds and carcinogenesis].

Archiv fur Geschwulstforschung, 1984
Starting with a brief outline of the general toxic effects of selenium compounds, their biological importance for the organism as a trace element and with an analysis of the different hypotheses on the action mechanism of selenium and selenium compounds, a survey is provided in which way selenium compounds may influence malignant transformation and ...
