QSAR study and molecular docking on indirubin inhibitors of Glycogen Synthase Kinase-3

23-10-2012 | Luminita Crisan, Liliana Pacureanu, Alina Bora, Sorin Avram, Ludovic Kurunczi, Zeno Simon, Central European Journal of Chemistry, 2012

The current study describes the development of in silico models based on a novel alternative of the MTD-PLS methodology (Partial-Least-Squares variant of Minimal Topologic Difference) developed by our group to predict the inhibition of GSK-3β by indirubin derivatives. The new MTD-PLS ...

Fully automated chip-based nanoelectrospray combined with electron transfer dissociation for high throughput top-down proteomics

23-10-2012 | Corina Flangea, Catalin Schiopu, Florina Capitan, Cristina Mosoarca, Marilena Manea, Eugen Sisu, Alina D. Zamfir, Central European Journal of Chemistry, 2012

The conventional protocol for protein identification by electrospray ionization mass spectrometry (MS) is based on enzymatic digestion which renders peptides to be analyzed by liquid chromatography-MS and collision-induced dissociation (CID) multistage MS, in the so-called bottom-up approach. ...

Mechanochemical synthesis of thenoyltrifluoroacetone-1,10-phenanthroline europium complex

20-09-2012 | Joana T. Zaharieva, Maria Milanova, Dimitar Todorovsky, Central European Journal of Chemistry, 2012

The paper considers the possibilities for mechanochemical synthesis of rare earth complexes. The complex Eu(TTA)3·phen (HTTA — 2-thenoyltrifluoroacetone, phen — 1,10-phenanthroline) is synthesized by mechanical treatment of a mixture of EuCl3.6H2O, HTTA, phen and NaOH in planetary ball mill ...

Excess interfacial energy change of solid/aqueous salt solution system with increasing salt concentration at a constant charge-determining ion activity based on the Gibbs equation and ionic components of charge

20-09-2012 | Tomasz Ratajczak, Jan Drzymala, Central European Journal of Chemistry, 2012

A thermodynamic equation relating the change of interfacial excess (Gibbs) energy in the solid/aqueous salt solution system, caused by a variation of concentration of inorganic salt at a constant charge-determining ion activity, temperature and pressure, is derived. The equation is based on ...

Mimicking the morphology of long bone

20-09-2012 | Anton Ficai, Ecaterina Andronescu, Denisa Ficai, Maria Sonmez, Madalina Georgiana Albu, Georgeta Voicu, Central European Journal of Chemistry, 2012

The aim of this work was to mimic the stratified structure of the median region of long bones. Starting from this desideratum, more COLL/HA composite materials with different morphology were synthesized and characterized, each of these materials mimicking one layer of long bone (endo- and ...

Magnetic resonance study of carbon encapsulated Ni nanoparticles

20-09-2012 | Marta Bobrowska, Janusz Typek, Grzegorz Zolnierkiewicz, Kamil Wardal, Niko Guskos, Iwona Pelech, Marcin Podsiadly, U ..., Central European Journal of Chemistry, 2012

Magnetic resonance study of six samples consisting of carbon encapsulated nickel nanoparticles or carbon nanotubes ended with such nickel nanoparticles was carried out at room temperature. Samples of Ni/C were prepared by carburization of nanocrystalline nickel by ethylene (C2H4) and methane ...

Polybenzene multitori

20-09-2012 | Beata Szefler, Mircea V. Diudea, Central European Journal of Chemistry, 2012

Polybenzene unit BT_48 can dimerize either by identification of 8-membered rings to provide a diamond-like fcc net or by identifying the opening 12-membered rings to form intercalated dendrimer-dimers which can further grow and rather quickly superimpose over the diamond-like network. The ...

Simultaneous analysis of first-line anti-tuberculosis drugs in tablets by UV spectrophotometry compared to capillary zone electrophoresis

20-09-2012 | Luiza F. Marcellos, Adriana F. Faria, Marcus V. N. de Souza, Mariana R. Almeida, Guilherme P. Sabin, Ronei J. Poppi, ..., Central European Journal of Chemistry, 2012

The development and optimization of a novel UV spectrophotometric methodology was proposed for simultaneous analysis of ethambutol (ETB), isoniazid (ISO), rifampicin (RIF) and pyrazinamide (PYR), using multivariate calibration based on the partial least squares method (PLS). The methodology ...

Chitosan/anionic surfactant microparticles synthesized by high pressure spraying method for removal of phenolic pollutants

20-09-2012 | Sandu Peretz, Manuela Florea-Spiroiu, Dan-Florin Anghel, Daniela Bala, Florina Branzoi, Jose-Calderon Moreno, Central European Journal of Chemistry, 2012

Biopolymeric microparticles were prepared by rapid expansion of high pressure CO2-chitosan (Chi) solution in sodium bis-(2-ethyl hexyl) sulfosuccinate (AOT) solution. At pressures higher than 2 MPa, ultrafine particles were formed while under this value, wires were obtained. The formation of ...
