Electrochemistry of active chromium, part IV: Dissolution of chromium in deaerated sulfuric acid / Elektrohemija aktivnog hroma, deo IV - rastvaranje hroma u deaeriranom vodenom rastvoru sumporne kiseline
(Serbian Chemical Society, 2004)
Chromium dissolution in aqueous sulfuric acid solutions in the pH range 0.5 –3 was studied electrochemically by the potentiostatic or very slow potentiodynamic method, and by the analyses of the Cr ion concentrations in ...
Protein covalent modification of biologically active quinones / Kovalentne modifikacije proteina biološki aktivnim hinonima
(Serbian Chemical Society, 2004)
The avarone/avarol quinone/hydroquinone couple shows considerable antitumor activity. In this work, covalent modification of β-lactoglobulin by avarone and its derivatives as well as by the synthetic steroidal quinone ...
Noble metal binding on macroporous poly(GMA-co-EGDMA) modified with ethylenediamine / Vezivanje plemenitih metala za makroporozni poli(GMA-co-EGDMA)kopolimer modifikovan sa etilendiaminom
(Serbian Chemical Society, 2004)
Macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), p(GME), was synthesized by suspension copolymerization and modified by reaction of the pendant epoxy groups with ethylenediamine. The ...
Study of supported Pt and PtRu catalysts in methanol and formic acid oxidation
(Trans Tech Publications Ltd, Switzerland, 2004)
The kinetics of methanol and formic acid oxidation on supported Pt and Pt2Ru3 catalysts are measured in 0.5 M H2SO4 at ambient temperature using thin-film rotating disc electrode (RDE) method. Both catalysts are characterized ...
Electrostatic surface potential calculation on several new halogenated benzimidazole-like dopaminergic ligands
(Wiley-VCH Verlag, 2004)
We examined the effects of the electron density distribution (electrostatic surface potential; ESP) of several new benzimidazole-type ligands on their binding affinity for the D 1 and D 2 dopamine receptors (DAR). Receptors ...
Modeling of the D2 dopamine receptor arylpiperazine binding site for 1-{2-[5-(1H-benzimidazole-2-thione)]ethyl}-4-arylpiperazines
(Wiley-VCH Verlag, 2004)
Docking of several 1-{2-[5-(1H-benzimidazole-2-thione)]ethyl}-4- and 1-benzylarylpiperazines to the D 2 dopamine receptor (DAR) was examined. The binding pocket of the D 2 DAR defined according to Teeter and DuRand [1] was ...
Superoxide dismutase activity as a function of culture aging of B-16 mouse melanoma cells / Aktivnost superoksid-dismutaze tokom maturacije kulture ćelija b-16 melanoma miša
(Serbian Chemical Society, 2004)
The C3 clone of B-16 mouse melanoma was cultured for 1, 6 and 9 days and analyzed. The changes which are not directly linked to melanogenesis in the B-16 / C3 cultures during their maturation were characterized. Early (1 ...
Synthesis of 5-azaandrostane-3β,17β-diol protected at the 17β-hydroxyl group
(Serbian Chemical Society, 2004)
In the present paper, the preparation of 3β-hydroxy-17β-dimethyl- tert-butylsilyloxy-5-azaandrostane (15) in fourteen steps is described. B-nor-17-oxoandrost-5-en-3β-yl acetate (1) 1,2 was used as the starting material, ...
Tetrahydrofuran-type sesquiterpenes from Artemisia lobelii All. var. canescens (DC.) Briqu. and Artemisia lobelii All. var. biasolettiana (Vis.) K. Maly
(Oxford : Pergamon-Elsevier Science Ltd, 2004)
The synthesis and preliminary pharmacological evaluation of the racemic cis and trans 3-alkylfentanyl analogues / Sinteza i preliminarni farmakološki testovi recemskih cis i trans 3-alkilanaloga fentanila
(Serbian Chemical Soc, Belgrade, 2004)
A general five step method for the synthesis of 3-alkylfentanyl analogues (i.e. cis and trans 3-alkyl-4-anilidopiperidines 6.1-6.6) has been developed, The starting N-phenethyl-4-piperidone 1 was first converted into the ...
