Chemical composition of white currant seed extract / Hemijski sastav ekstrakta semenki bele ribizle
(Serbian Chemical Soc, Belgrade, 2011)
From the seeds of white currant (Ribes rubrum, cv. White Champagne), a new sesquiterpenoid glycoside 1 was isolated, along with two known compounds: dihydrophaseic acid 3'-O-beta-D-glucopyranoside (2), and 3-carboxymethy ...
Statistical dependence of protein secondary structure on amino acid bigrams [Statistička zavisnost sekundarne strukture proteina od frekvencije bigrama aminokiselina] / Statistička zavisnost sekundarne strukture proteina od frekvencije digrama aminokiselina
(Chemical Industry and Chemical Engineering Quarterly / CICEQ, 2006)
The statistical dependence of protein secondary structure on amino acid bigram frequencies was studied. Proteins in the PDBSELECT subset of the Protein Data Bank database were investigated. Protein secondary structures ...
The kinetics of the reduction of the lipophilic quinone avarone by n-alkyl-1,4-dihydronicotinamides of various lipophilicities
(Serbian Chemical Soc, Belgrade, 1999)
Several NADH model compounds, N-alkyl-1,4-dihydronicotinamides, some of them possessing amphiphilic properties, have been synthesized, and the kinetics of their reaction with a biologically active liphophilic quinone, ...
NaY zeolite: A useful catalyst for nitrile hydrolysis
(Molecular Diversity Preservation International, Basel, 2000)
The NaY zeolite catalysed hydrolysis of nitriles to primary amides is reported. It is found that aryl nitriles with strong electron-withdrawing substituents and cyanopyridines are readily hydrolysed in the water suspension, ...
Molecular orbital study of the oxidation of steroidal phenols into quinols and epoxyquinols / Molekulsko-orbitalno proučavanje oksidacije fenola u hinole i epoksihinole
(Serbian Chemical Soc, Belgrade, 2000)
The MO study showed that the radical oxidation of phenols into quinols occurs readily. Further radical oxidation (in the m-CPBA/(BzO)(2)/hv system) of quinols occurs through appropriate biradical species with an activation ...
Spin state relaxation of iron complexes: The case for OPBE and S12g
(Serbian Chemical Soc, Belgrade, 2015)
The structures of nine iron complexes that show a diversity of experimentally observed spin ground states were optimized and analyzed using the Density Functional Theory (DFT). An extensive validation study of the new S12g ...
A new depsidone of Lobaria pulmonaria with acetylcholinesterase inhibition activity
(Informa Healthcare, London, 2013)
The phytochemical investigation conducted on a foliose lichen, Lobaria pulmonaria (L.) Hoffm. (Lobariaceae), led to the isolation of a new depsidone in the form of its diacetate derivative which showed a moderate ...
Use of the sulfide minerals pyrite and chalcopyrite as electrochemical sensors in non-aqueous solutions. The potentiometric titration of weak acids in alcohols
(Versita, Warsaw 41, 2009)
Natural monocrystalline pyrite and chalcopyrite were examined as new indicator electrodes for the potentiometric titration of weak acids in tert-butanol and iso-propanol. The electrodes investigated demonstrated a linear ...
Importance of N-terminal proline for the promiscuous activity of 4-oxalocrotonate tautomerase (4-OT)
(Serbian Chemical Soc, Belgrade, 2016)
Michael addition of aldehydes to nitro-olefins is an effective method to obtain useful chiral gamma-nitroaldehydes. gamma-Nitroaldehydes are precursors for chiral gamma-aminobutyric acid analogues, which have numerous ...
3D electrogenerated chemiluminescence: from surface-confined reactions to bulk emission
(Royal Soc Chemistry, Cambridge, 2015)
Among luminescence techniques, electrogenerated chemiluminescence (ECL) provides a unique level of manipulation of the luminescent process by controlling the electrochemical trigger. Despite its attractiveness, ECL is by ...
