A New One-Pot Synthetic Method for Selenium-Containing Medium-Sized α,β-Unsaturated Cyclic Ketones Abstract. The reaction of tetrahydroselenopyran-2-one (7) with ethynyllithiums 20a-h , followed by treatment with aqueous 5% H 2 SO 4 successfully led to a two-carbon ring expansion to give the 2-substituted 5,6,7,8-tetrahydroselenocin-4-ones 21a-h in 43-95% yields. Seven- to nine

Selenium-Containing Polysaccharide-Protein Complex in Se
The role of selenium (Se) and Ulva fasciata as potent cancer chemopreventive and chemotherapeutic agents has been supported by epidemiological, preclinical, and clinical studies. In this study, Se-containing polysaccharide-protein complex (Se-PPC), a novel organoselenium compound, a Se-containing polysaccharide-protein complex in Se-enriched Ulva fasciata, is a potent anti-proliferative
Selenium-containing block copolymers and their oxidation
A selenium -containing amphiphilic block copolymer (PEG-PUSe-PEG) with a hydrophobic polyselenide block and two hydrophilic poly (ethylene glycol) (PEG) blocks was synthesized via polymerization of toluene diisocyanate (TDI) with monoselenide -containing diols and subsequent termination with PEG monomethylether.
Selenoneine, a Novel Selenium-Containing Compound
Abstract. The selenium (Se)-containing antioxidant selenoneine (2-selenyl-N α,N α,N α-trimethyl-l-histidine) has recently been discovered to be the predominant form of organic Se in tuna blood. Although dietary intake of fish Se has been suggested to reduce methylmercury (MeHg) toxicity, the molecular mechanism of MeHg detoxification by Se has not yet been determined. Here, we report
MAMMALIAN SELENIUM-CONTAINING PROTEINS |
Abstract Mammalian selenium-containing proteins can be divided into three groups: proteins containing nonspecifically incorporated selenium, specific selenium-binding proteins, and specific selenocysteine-containing selenoproteins. Selenoproteins with known functions identified so far include five glutathione peroxidases, two deiodinases, several thioredoxin reductases, and selenophosphate
Relationship between selenium, immunity and resistance
Abstract 1. Food selenium content, selenium supply and selenium needs are presented, along with methods of evaluation of selenium status. Glutathione peroxidase, a selenium-containing enzyme, is ubiquitous in the organism. 2. Some experimental studies on animal models reported a positive relationship between selenium status and resistance against infections. 3. Only one study in humans

Preliminary studies on selenium-containing proteins in
Abstract An approach for screening and resolving selenium-containing plant proteins was developed based on the combination of sample preparation and multi-dimensional liquid chromatography coupled to ICP-MS. Different protein extraction protocols were investigated. A 24 h dodecylsulfate-mediated protein extraction in a sonication bath followed by acetone precipitation was found to be optimal

PBISe, a novel selenium-containing drug for the treatment
In conclusion, selenium-containing PBISe has been shown to be a more effective therapeutic agent than PBIT. It kills melanoma cells >10-fold more effectively than PBIT and cultured cancer cells are 2- to 5-fold more sensitive than normal cells. Compared with PBIT, PBISe decreases the growth of established melanomas by 30% to 50% inducing a 2-fold increase in apoptosis and 2- to 3-fold decrease

Removal of selenium containing algae by the bivalve
Selenium (Se) is an essential micronutrient for animals and humans with a relatively narrow margin between nutritional essentiality and potential toxicity. Even though our previous studies have demonstrated algae could efficiently remove Se, mainly through volatilization, concern is raised about eco-risks posed by the remaining Se in algae.
Selenium-containing supra-amphiphiles Materials
Selenium chemistry possesses many unique properties and selenium-containing polymers made by covalent synthesis have developed enormously in the past few decades. Supra-amphiphiles built on selenium-containing species offer more opportunities for functional systems without too many synthetic efforts. This review will give a brief overview of different types of selenium-containing supra

Selenium in the Immune System | The Journal of Nutrition
Abstract. Selenium as an essential component of selenocysteine-containing protein is involved in most aspects of cell biochemistry and function. As such, there is much potential for selenium to influence the immune system. For example, the antioxidant glutathione peroxidases are likely to protect neutrophils from oxygen-derived radicals that are produced to kill ingested foreign organisms
