Synthesis and Structure of New 5-(Arylidene)-3-(4-methylbenzoyl)thiazolidine-2,4-diones
(Wiley-Blackwell Publishing, Inc, Malden, 2010)
The derivatives of 5-substituted-2,4-thiazolidinedione have a broad spectrum of biological activities. In this article, new 5-(arylidene)-3-(4-methylbenzoyl)thiayolidine-2,4-diones 3a-k, with arylidene groups such as ...
The impact of Schiff bases on antibiotic production by Streptomyces hygroscopicus
(Medicinal Chemistry Research, 2010)
A media consisting of isatin-Schiff bases (isatin-3-thiosemicarbazone, isatin-3-semicarbazone, and isatin-3-phenylhydrazone) was developed to maximize the production of antibiotics Hexaene H-85 and Azalomycine B by ...
Ring- and side-group conformational properties of di-O-acylated xylopyranosides: A computational study
(Elsevier, 2015)
The conformational properties (C-4(1), C-1(4), and skew ring structures, side chain torsion) of methyl 2,4-(1) and 3,4-O-diacetyl (2) as well as 2,4-(3) and 3,4-O-dibenzoyl (4)-SS-D-xylopyranoside are calculated by ...
Systemic NF-kappaB activation in blood cells of breast cancer patients
(Maney Publishing, 2006)
There is a well-established role for reactive oxygen and nitrogen species, chronic inflammation and immune response in the pathogenesis of breast cancer. Complex interactions between breast cancer cells and surrounding ...
STACKING INTERACTIONS BETWEEN PYRIDINE FRAGMENTS IN CRYSTAL STRUCTURES OF TERPYRIDYL COMPLEXES
(Univ Babes-Bolyai, Cluj-Napoca, 2010)
In the crystal structures of terpyridyl complexes from the Cambridge Structural Database (CSD) stacking interaction between the pyridine fragments were studied. Square-planar complexes where the distance between the centers ...
Electroreduction of cefetamet on mercury, platinum and gold electrodes / Elektroredukcija cefetameta na elektrodama od žive, platine i zlata
(Serbian Chemical Society, 2000)
The electroreduction of cefetamet (CEF) using gold and platinum electrodes has been investigated in slightly alkaline medium (pH 8.40) where adsorption, previously observed at mercury electrode, was pronounced. This ...
Reduction of Oxygen at a NaX-Ag Composite Electrode and Its Application to the Determination of Oxygen in Aqueous Media
(Maik Nauka/Interperiodica/Springer, New York, 2010)
A composite mixture Ag-NaX zeolite (silver concentration 16.7% w/w) is synthesized usingimpregnation and thermal decomposition. For silver impregnation, a solution of an Ag acetylacetonate complex in acetone was used. ...
Carbon monoxide oxidation on a Au(111) surface modified by spontaneously deposited Ru / Оксидација CO на Au(111) површини модификованој спонтано депонованим Ru
(Belgrade : Serbian Chemical Society, 2001)
The spontaneous deposition of Ru on Au(111) was performed in 10-3 M RuCl3-0.5 M H2SO4 solution. The obtained surface was characterized by STM under potential control in 0.5 M H2SO4 solution. The coverage of the Au(111) ...
Thermal properties of poly(urethane-ester-siloxane)s based on hyperbranched polyester
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Novel polyurethanes (PUs) were synthesized using hydroxy-terminated hyperbranched polyester (BH-20) and 4,4'-methylenediphenyl diisocyanate (MDI) as hard segments and hydroxy-terminated ethylene oxide-poly(dimethylsiloxa ...
Oxidation of dibenzothiophene as a model substrate for the removal of organic sulphur from fossil fuels by iron(III) ions generated from pyrite by Acidithiobacillus ferrooxidans / Oksidacija dibenzotiofena kao model-supstrata za izdvajanje organskog sumpora iz fosilnih goriva dejstvom gvožđe(III)-jona generisanog iz pirita pomoću Acidithiobacillus ferrooxidans
(Serbian Chemical Society, 2007)
Within this paper a new idea for the removal of organically bonded sulphur from fossil fuels is discussed. Dibenzothiophene (DBT) was used as a model compound of organicmolecules containing sulphur. This form of ...
