Preparation and studies on immobilized alpha-glucosidase from baker's yeast Saccharomyces cerevisiae / Dobijanje i proučavanje imobilizacije α-glukozidaze iz pekarskog kvasca Saccharomyces cerevisiae
(Serbian Chemical Soc, Belgrade, 2007)
alpha-Glucosidase from S. cerevisiae was covalently immobilized onto Sepabeads EC-EA by the glutaraldehyde method. An analysis of the variables controlling the immobilization process is first presented and it is shown that ...
Radical reactions of xanthates: annulation of the cyclopentene ring / Radikalske reakcije ksantata - anelacija ciklopentenovog prstena
(Serbian Chemical Soc, Belgrade, 2007)
Homoallylic radicals, generated from the corresponding xanthates, react with terminal alkynes to give cyclopentene derivatives in moderate yields.
Antimalarial peroxides: the first intramolecular 1,2,4,5-tetraoxane / Antimalarijski peroksidi - prvi intramolekulski 1,2,4,5-tetraoksan
(Serbian Chemical Soc, Belgrade, 2002)
An intramolecular steroidal 1,2,4,5-tetraoxane has been synthesised in six steps starting from methyl 3-oxo-7alpha,12alpha-diacetoxy-5beta-cholan-24-pate. The synthesised 1,2,4,5-tetra-aoxane has moderate in vitro antimalarial ...
Sterol composition of the Adriatic sea algae Ulva lactuca, Codium dichotonium, Cystoseira adriatica and Fucus virsoides / Sastav sterolne smese algi jadranskog mora Ulva lactuca, Codium dichotomum, Cystoseira adriatica i Fucus virsoides
(Serbian Chemical Soc, Belgrade, 2005)
The sterol composition of two green algae and two brown algae from the South Adriatic was determined. In the green alga Ulva lactuca, the principal sterols, were cholesterol and isofucosterol. In the brown alga Cystoseira ...
Insulin-induced glycosylphosphatidylinositol (GPI) binding to red cell membrane proteins / Vezivanje glikozilfosfatidilinozitola(GPI-a) za membranske proteine eritrocita pod dejstvom insulina
(Journal of the Serbian Chemical Society, 2002)
In this work GPI binding to membrane proteins from erythrocytes of insulinoma patients for whom prolonged hyperinsulinism and hypoglycemia were characteristic, as well as from normal erythrocytes incubated with supraphysiological ...
Flavonoids from the aerial parts of Onobrychis montana subsp scardica / Flavonoidi iz nadzemnih delova Onobrychis montana subsp. scardica
(Serbian Chemical Soc, Belgrade, 2008)
Rutin (1, main constituent) and two flavone C-glycosides, vitexin (2) and vitexin 2 ''-O-alpha-rhamnopyranoside (3) were isolated from the aerial parts of Onobrychis montana subsp. scardica. They were identified by (1)H-NMR, ...
The synthesis and characterization of complexes of zinc(II), cadmium(II), platinum(II) and palladium(II) with potassium 3-dithiocarboxy-3-aza-5-aminopentanoate / Sinteza i karakterizacija kompleksa cink(II), kadmijum(II), platina(II),i paladijum(II) sa kalijum-3-ditiokarboksi-3-aza-5-aminopentanoatom
(Serbian Chemical Soc, Belgrade, 2004)
Complexes of zinc(lI), cadmium(II). platinum(lI) and palladium(II) with a new poly-dentate dithiocarbamate ligand, 3-dithiocarboxy-3-aza-5-aminopentanoate (daap(-)), of the type M(daap)(2).nH(2)O (M = Zn(II), Cd(II), n = ...
Conformational analysis of three germacranolides by the PM3 semi-empirical method / Konformaciona analiza tri germakranolida PM3 semi-empirijskom metodom
(Serbian Chemical Soc, Belgrade, 2003)
The conformations of the C-6 lactomized germacranolides 1-3 were calculated by applying the PM3 semi-empirical method, The low-temperature H-1-NMR spectra of parthenolide (1) were also measured. The relations between the ...
Covalent glycoinositolphospholipid (GPI) binding to hemoglobin is associated with insulin-activation of erythrocyte membrane protease / Kovalentno vezivanje glikoinozitolfosfolipida (GPI) za hemoglobin pod dejstvom insulina praćeno je aktiviranjem proteaze iz membrane eritrocita
(Serbian Chemical Soc, Belgrade, 2004)
Recently, it was demonstrated that prolonged hyperinsulinism associated with hypoglycemia, both in vivo and in vitro, caused covalent glycoinositolphospholipid (GPI) binding to the C termini of both hemoglobin beta-chains, ...
Chemical aspects of the influence of cobalt ions on ATPase activity / Hemijski aspekt uticaja jona kobalta na aktivnost ATP-aza
(Serbian Chemical Soc, Belgrade, 2000)
The influence of Co2+ ions on the activities of Na+/K+-ATPase and Mg2+-ATPase, enzymes from rat brain synaptic plasma membrane, was studied. The aim of this study was to investigate the inhibition of both ATPases activities ...
