Rhodium- and palladium-catalyzed 1,5-substitution reactions of 2-En-4-yne acetates and carbonates with organoboronic acids
(American Chemical Society, 2011-08)
Two methods involving the rhodium-catalyzed reaction of 2-en-4-yne acetates and the palladium-catalyzed reaction of 2-en-4-yne carbonates with organoboronic acids were investigated; both afforded exclusively the (E)-configured ...
BODIPY-conjugated chitosan nanoparticles as a fluorescent probe
(Taylor & Francis, 2017-10)
Recently, development of fluorescent nanoparticle-based probes for various bioimaging applications has attracted great attention. This work aims to develop a new type fluorescent nanoparticle conjugate and evaluate its ...
Rhodium-catalysed alkoxycarbonylative cyclisation reactions of 1,6-enynes
(Wiley-VCH Verlag, 2011-04)
The rhodium-catalysed carbonylation of 1,6-enynes possessing an electron-deficient alkenyl moiety in an alcohol reagent in the presence of a rhodium complex proceeded stereo- and chemoselectively to afford exocyclic α,β-enoates.
Determination of minerals and trace elements in soils and the relation with its concentrations in sugar beets
(Chemical Publishing Co., 2010)
Twelve sugar beets and corresponding soil samples from the plantation near Malatya, Turkey were analyzed for mineral and trace element contents. Thirteen metals (Al, Ca, Cd, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Se and Zn) were ...
Non-direct sequence ions in the tandem mass spectrometry of protonated peptide amides - An energy-resolved study
The fragmentation reactions of the MH+ ions of Leu-enkephalin amide and a variety of heptapeptide amides have been studied in detail as a function of collision energy using a QqToF beam type mass spectrometer. The initial ...
Adsorption of methylene blue from aqueous solution on high lime fly ash: Kinetic, equilibrium, and thermodynamic studies
(Taylor & Francis, 2012-01)
Kinetic, equilibrium, and thermodynamic studies were performed for the batch adsorption of methylene blue (MB) on the high lime fly ash as a low cost adsorbent material. The studied operating variables were adsorbent amount, ...
A BODIPY-based reactive probe for the detection of Au(iii) species and its application to cell imaging
(Royal Society of Chemistry, 2014-06)
A BODIPY-based fluorescent probe bearing a pyridyl hydrazone motif responds selectively to Au(III) ions through an irreversible C[double bond, length as m-dash]N bond hydrolysis reaction. Gold species, besides their ...
Enthalpy-driven selective loading of CdSe0.75S0.25 nanoalloys in triblock copolymer polystyrene-b-polyisoprene-b-polystyrene
CdSe0.75S0.25 nanoalloys were blended with asymmetric triblock copolymer of polystyrene-b-polyisoprene-b-polystyrene(PS-SIS) in tetrahydrofuran. The fraction of styrene block varies from 14 to 22% with respect to isoprene ...
CRM1 inhibitory and antiproliferative activities of novel 4′-alkyl substituted klavuzon derivatives
Klavuzons are 6-(naphthalen-1-yl) substituted 5,6-dihydro-2H-pyran-2-one derivatives showing promising antiproliferative activities in variety of cancer cell lines. In this work, racemic syntheses of nine novel 4′-alkyl ...
Synthesis and Topoisomerase I inhibitory properties of klavuzon derivatives
Klavuzon is a naphthalen-1-yl substituted α,β-unsaturated δ-lactone derivative, and is one of the anti-proliferative members of this class of compounds. Asymmetric and racemic syntheses of novel α,β-unsaturated δ-lactone ...
