Lipophilicity of some guaianolides isolated from two endemic subspecies of Amphoricarpos neumayeri (Asteraceae) from Montenegro
(Biomedical Chromatography, 2009)
In this study 10 guaianolide-type sesquiterpene γ-lactones named amphoricarpolides, isolated from the aerial parts of two endemic subspecies of Amphoricarpos neumayeri (ssp. neumayeri and ssp. murbeckii Bosnjak), were ...
Study of Nd-Fe-B alloys with nonstoichiometric Nd content in optimal magnetic state
(International Institute for the Science of Sintering, Beograd, 2009)
Characterization of two rapid-quenched Nd-Fe-B alloys with nonstoichiometric Nd content in the optimized magnetic state was carried out using the X-ray diffractometry (XRD), 57Fe Mössbauer spectroscopic phase analysis (MS), ...
Leucine aminopeptidase from Streptomyces hygroscopicus is controlled by a low molecular weight inhibitor
(Society of Fermentation and Bioengineering, 2002)
In culture filtrate of Streptomyces hygroscopicus a producer of polyketide antibiotics, a leucine aminopeptidase and its autogenous inhibitor were detected. The leucine aminopeptidase was purified 4573-fold with yield of ...
Effects of O2+ ions beam irradiation on crystal structure of rare earth sesquioxides
(Elsevier, 2009)
We report the results of ion irradiation influence on rare earth sesquioxides structure, which are materials of practical importance as a radiation resistant ceramics in nuclear applications. Y2O3, Gd2O3 and Er2O3 sesquioxides ...
Relationships between structure, retention and biological activity of some Schiff base ligands and their complexes
(Biomedical Chromatography, 2008)
The lipophilicity of a series of Schiff base ligands and their complexes with nickel(II) and copper(II) has been determined by reversed-phase thin-layer chromatography using binary dioxane-water mobile phase. Chelate ligands ...
Syntheses, characterization and antimicrobial activity of the first complexes of Zn(II), Cd(II) and Co(II) with N-benzyloxycarbonylglycine. X-ray crystal structure of the polymeric Cd(II) complex
(Elsevier S.A., 2008)
For the first time, complexes of Zn(II), Cd(II) and Co(II) (1-3) with N-benzyloxycarbonylglycine have been synthesized and characterized. The complexes adopt tetrahedral, pentagonal-bipyramidal and octahedral geometry, ...
Phenolics, lignin content and peroxidase activity in Picea omorika lines
(Biologia Plantarum, 2006)
We analyzed low molecular mass phenolics, lignin content and both soluble and cell wall bound peroxidase activity in the needles of three Picea omorika (Pancic) Purkyne lines grown in the generative seed orchard. The highest ...
Introduction of a methyl group in alpha- or beta-position of 1-heteroarylethyl-4-phenyl-piperazines affects their dopaminergic/serotonergic properties
(Wiley-VCH Verlag Gmbh, Weinheim, 2001)
1-(2-Heteroarylalkyl)-4-phenylpiperazines containing methyl group in either the alpha- or the beta-position of the side alkyl chain were synthesized as racemic mixtures. They were evaluated for in vitro binding affinity ...
Antitumor effects of a natural anthracycline analog (Aloin) involve altered activity of antioxidant enzymes in HeLaS3 cells
(Taylor & Francis Inc, Philadelphia, 2007)
The anti proliferative and cytotoxic potential of the natural anthracycline aloin from Aloe vera was tested on human uterine carcinoma HeLaS3 cells. Aloin showed a pronounced antiproliferative effect at physiological ...
Iron catalyzed conversion of NO into nitrosonium (NO+) and nitroxyl (HNO/NO-) species
(Elsevier, 2004)
The conversion of NO into its congeners, nitrosonium (NO+) and nitroxyl (HNO/NO-) species, has important consequences in NO metabolism. Dinitrosyl iron complex (DNIC) combined with thiol ligands was shown to catalyze the ...
