Synthesis of unstable cyclic peroxides for chemiluminescence studies
Peróxidos cíclicos de quatro membros são intermediários de alta energia importantes em diversas transformações quimi e bioluminescentes. Especificamente, a-peroxilactonas (1,2-dioxetanonas) têm sido consideradas sistemas modelo para a eficiente bioluminescência do vaga-lume. Contudo, a preparação deste tipo de compostos altamente instáveis é extremamente difícil e, por isso, apenas alguns pouco...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولMechanistic aspects of the relationship between low-level chemiluminescence and lipid peroxides in oxidation of low-density lipoprotein.
In this study oxidation of low-density lipoprotein (LDL) induced by different Cu2+ concentrations was investigated. Lipid peroxidation was assessed by monitoring low-level chemiluminescence (LL-CL), conjugated diene hydroperoxide (CD) and alpha-tocopherol (TocOH), the major lipophilic antioxidant in LDL. At high Cu2+ concentration, LDL oxidation was characterised by CD formation, LL-CL emission...
متن کاملSynthesis of Bis ( indolyl ) methanes by using
A novel synthetic methodology for the synthesis of Bis(indolyl)methanes by using catalytic amount of ferric triflate was described Introduction Bis(indolyl)methanes consists two substituted indole units in the molecule. Bis indole derivatives are reported to exhibit a wide spectrum of pharmacological activities such as cytotoxic, antitumor antimicrobial [1] and antiactivities. [2] For the past ...
