Synthesis and biological activity of amino acid derivatives of avarone and its model compound
(Oxford : Pergamon-Elsevier Science Ltd, 2015)
A series of eighteen derivatives of marine sesquiterpene quinone avarone and its model system tert-butylquinone with amino acids has been synthesized by nucleophilic addition of amino acids to the quinones. In vitro cytotoxic ...
Chemo-protective and regenerative effects of diarylheptanoids from the bark of black alder (Alnus glutinosa) in human normal keratinocytes
(Elsevier, 2015)
Medicinal plants are recognized from ancient times as a source of diverse therapeutic agents and many of them are used as dietary supplements. Comprehensive approaches are needed that would identify bioactive components ...
Solvatochromism of symmetrical 2,6-distyrylpyridines. An experimental and theoretical study
(Amsterdam : Elsevier, 2015)
Seven symmetrical 2,6-distyrylpyridines, phenyl-substituted with hydrogen-bond donors, hydrogenbond
acceptors, halogens and hydrophobic moieties were synthesized and their spectroscopic characterization
was done. Solvent ...
CaNa(2)EDTA chelation attenuates cell damage in workers exposed to lead-a pilot study
(Elsevier Ireland Ltd, Clare, 2015)
Lead induced oxidative cellular damage and long-term persistence of associated adverse effects increases risk of late-onset diseases. CaNa(2)EDTA chelation is known to remove contaminating metals and to reduce free radical ...
Effect of supplemental feed type on water quality, plankton and benthos availability and carp (Cyprinus carpio L.) growth in semi-intensive monoculture ponds
(Wiley-Blackwell, Hoboken, 2015)
A four-and-a-half months study was conducted in nine earthen ponds to evaluate the addition of different supplemental feeds as a management tool for enhancing natural food availability and common carp growth, while maintaining ...
Contribution of anion-pi interactions to the stability of Sm/LSm proteins
(Springer, New York, 2015)
We have analyzed the influence of anion-pi interactions to the stability of Sm/LSm assemblies. The side chain of Glu is more likely to be in anion-pi interactions than Asp. Phe has the highest occurrence in these interactions ...
Applicability of Calculated Vitrinite Reflectance for Assessment of Source Rock's Organic Matter Maturity in Hyperthermal Basins (Banat Depression, Serbia)
(Maik Nauka/Interperiodica/Springer, New York, 2015)
Middle and Upper Miocene petroleum source rocks from the Banat Depression, SE Pannonian Basin (Serbia) were investigated. These rocks contain organic matter (OM) in a relatively wide range of maturity (from early to late ...
Study of the intramolecular Heck reaction: synthesis of the bicyclic core of corialstonidine
(Oxford : Pergamon-Elsevier Science Ltd, 2015)
The intramolecular Heck reaction has been examined for the preparation of the core bicyclic structure of corialstonidine. Initial attempts to cyclise a vinyl iodide moiety onto a cyclic allyl alcohol were complicated by ...
Structural, Magnetic, DFT, and Biological Studies of Mononuclear and Dinuclear Cu-II Complexes with Bidentate N-Heteroaromatic Schiff Base Ligands
(Wiley-V C H Verlag Gmbh, Weinheim, 2015)
Copper(II) complexes with the condensation derivative of methyl hydrazinoacetate and 2-acetylpyridine were synthesized. The X-ray crystal structures for both complexes revealed that they are polymerized isomers. A common ...
Reactions of superoxide dismutases with HS-/H2S and superoxide radical anion: An in vitro EPR study
(Academic Press Inc Elsevier Science, San Diego, 2015)
Interactions of hydrogen sulfide (HS-/H2S), a reducing signaling species, with superoxide dimutases (SOD) are poorly understood. We applied low-T EPR spectroscopy to examine the effects of HS-/H2S and superoxide radical ...
