The hybrid density functional theory (B3LYP) and ab initio molecular orbital (HF) based methods and Natural Bond Orbital (NBO) interpretation were used to analyze the conformational behaviors of 2,5,5-trimethyl-1,3,2-dioxaphosphinane 2-selenide (compound 1), 2,5,5-trimethyl-1,3,2-dithiaphosphinane 2-selenide (compound 2) and 2,5,5-trimethyl-1,3,2-diselena phosp...

Hydrogen selenide is a recurrent metabolite of selenium compounds. However, few experiments studied the direct link between this toxic agent and cell death. To address this question, we first screened a systematic collection of Saccharomyces cerevisiae haploid knockout strains for sensitivity to sodium selenide, a donor for hydrogen selenide (H(2)Se/HSe(-/)Se(2-)). Among the genes whose deletio...

The title compound, C(8)H(17)O(2)PS(2), displays a distorted tetra-hedral geometry around the P atom. The P atom is part of a six-membered ring with an isopropyl group in the equatorial position. The mol-ecules are linked by S-H⋯S hydrogen bonds in the crystal packing.

In the title mol-ecule, C(12)H(15)Cl(2)O(4)P, the cyclic dioxaphosphinane ring adopts a chair conformation. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into chains propagating along the b axis.

An enzyme preparation from Salmonella typhimurium catalyzes the conversion of 5-methylaminomethyl-2-thiouridine in tRNAs to 5-methylaminomethyl-2-selenouridine when supplemented with selenide and ATP. Similar preparations from a Salmonella mutant strain carrying a defective selD gene fail to catalyze this selenium substitution reaction. However, supplementation of the deficient enzyme preparati...

Background and Aims: Mercury, with its oxidative activity, causes damage to the antioxidant enzymes thus resulting in physiological disorders. Sodium selenide is an antioxidant that protects antioxidant enzymes. The aim of this study was to investigate the protective effect of sodium selenide on renal toxicity induced by mercuric chloride in rats. Materials and Methods: Animals were divided in...
