Synthesis of Allyl Acetates via Palladium-Catalysed Functionalisation of Allenes and 1,3-Dienes
(Stuttgart : Georg Thieme Verlag Kg, 2012)
pi-Allylpalladium intermediates are known to participate efficiently in transformations involving nucleophilic species. Exploring these processes, we have developed a method for the preparation of allyl acetates via ...
Chemical Composition of Currant Seed Extracts and Their Protective Effect on Human Lymphocytes DNA
(Wiley-Blackwell, Hoboken, 2012)
On the basis of LC/UV/MS analysis, 35 compounds from the extracts of seeds of black, red, and white currants (2 cultivars of each) were identified. Black currants cultivars contained protocatechuic acid and p-hydroxybenzoic ...
Decolorization of textile dyes and effluents using potato (Solanum tuberosum) phenoloxidase
(Elsevier Sci Ltd, Oxford, 2012)
Potatoes are desirable source for polyphenol oxidase (PPO, EC 1.14.18.1) purification because this enzyme can be purified from the food industry waste such are potato peels from potato chips industry. This paper presents ...
Fast and reliable method for simultaneous zymographic detection of glucoamylase and a-amylase in fungal fermentation
(Academic Press Inc Elsevier Science, San Diego, 2012)
Detection of alpha-amylase and glucoamylase in crude fermentation extracts using a single native electrophoresis gel and zymogram is described in this article. Proteins were printed on substrate gel and simultaneously onto ...
The mechanisms responsible for neuroprotective capacity of arylpiperazine dopaminergic ligands against cell death induced by sodium nitroprusside
(Elsevier, 2012)
A group of sixteen arylpiperazines had been previously synthesized and evaluated for atypical antipsychotic activity. Here we examined these compounds for their neuroprotective capacity. The affinity and agonist/antagonist ...
The dominant contribution on wet deposition of water-soluble main ions in the South-Eastern Adriatic region
(Versita, Warsaw, 2012)
The results of content of water-soluble ions measured in 604 samples of precipitation collected in South-Eastern Adriatic region during 6 years have been analyzed. The HYSPLIT model was used to study the air mass paths. ...
Population Variability of Nonacosan-10-ol and n-Alkanes in Needle Cuticular Waxes of Macedonian Pine (Pinus peuce Griseb.)
(Wiley-V C H Verlag Gmbh, Weinheim, 2012)
This is the first report on population variability of nonacosan-10-ol and n-alkanes in needle epicuticular waxes of Macedonian pine (Pinus peuce Griseb.) Hexane extracts of needle samples, originating from two natural ...
Synthesis, Spectral and Solid State Characterization of a New Bioactive Hydrazine Bridged Cyclic Diphosphonium Compound
(MDPI, 2012)
The facile preparation of a racemic hydrazine bridged diphosphonium compound possessing a ring system analogous to bicyclo[3.3.2]decane is reported. Although the reaction yield is low, the structure of the compound, which ...
The kinetics of the hydrogen oxidation reaction on WC/Pt catalyst with low content of Pt nano-particles
(Elsevier, 2012)
The catalytic activity of WC/Pt electrocatalysts towards hydrogen oxidation reaction (HOR) in acid solution was studied. Tungsten carbide (WC) prepared by polycondensation of resorcinol and formaldehyde in the presence of ...
pi-pi and cation-pi interactions in protein-porphyrin complex crystal structures
(The Royal Society of Chemistry, 2012)
In this study we have described the pi-pi and cation-pi interactions between the porphyrin ring and the protein part of porphyrin-containing proteins to better understand their stabilizing role. The number of pi-pi ...
