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 ...
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 ...
Comparison of two methods for removal of arsenic from potable water
(Vacuum, 2008)
Arsenic, well known of its toxicity, is present in potable water in many areas in the world, as well as in underground water used for water supply in Vojvodina, a region in Serbia. Its removal from raw water is necessary ...
Slow-wave EBG microstrip rat-race hybrid ring
(Iee-Inst Elec Eng, Hertford, 2005)
A new type of slow-wave EBG microstr p rat-race hybrid ring is presented. It effectively reduces the occupied area to 11% of the conventional rat-race hybrid ring. It does not need any impedance transformers on the ports.
Pulse and direct current plating of Ni-W alloys from ammonia-citrate electrolyte
(Elsevier, 2006)
The effect of the potential of deposition and electrode rotation rate on current efficiency and partial current density of nickel deposition from ammonia-citrate electrolyte with and without tungstate ions was investigated. ...
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, ...
Synthesis and biological evaluation of some 17-picolyl and 17-picolinylidene androst-5-ene derivatives
(Elsevier, 2007)
Starting from dehydroepiandrosterone (1) 17-picolyl (2), 17-picolinylidene (7), 17-picolinylidene-16-one (10 and 11), and 17-picolyl-16-one (15) derivatives of androst-5-ene were synthesized in one, two, four and five steps ...
Synthesis, characterization and antitumor activity of novel N-substituted α-amino acids containing ferrocenyl pyrazole-moiety
(Journal of Organometallic Chemistry, 2009)
A series of new N-[(3-ferrocenyl-1-phenylpyrazol-4-yl)methyl] α-amino acids were prepared and characterized by a range of spectroscopic techniques and cyclic voltammetry. The in vitro antitumor activity of all synthesized ...
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), ...
