Structural, Magnetic, DFT, and Biological Studies of Mononuclear and Dinuclear Cu-II Complexes with Bidentate N-Heteroaromatic Schiff Base Ligands
(Wiley-V C H Verlag Gmbh, Weinheim, 2015)
Copper(II) complexes with the condensation derivative of methyl hydrazinoacetate and 2-acetylpyridine were synthesized. The X-ray crystal structures for both complexes revealed that they are polymerized isomers. A common ...
Synthesis of Anatase Nanopowders by Sol-gel Method and Influence of Temperatures of Calcination to Their Photocatalitic Properties
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2015)
The titanium dioxide (TiO2) nanopowders were produced by sol-gel technique from tetrabutyl titanate as a precursor, varying the temperature of calcination (from 500 to 550 degrees C with the step of 10 degrees C). XRPD ...
Ni(II) complex with bishydrazone ligand: synthesis, characterization, DNA binding studies and pro-apoptotic and pro-differentiation induction in human cancerous cell lines
(Royal Soc Chemistry, Cambridge, 2016)
A new Ni(II) complex, [Ni(L)(H2O)] (1), with diethyl 3,3'-(2,2'-(1,1'-(pyridine-2,6-diyl) bis(ethan-1-yl-1-ylidene)) bis(hydrazin-1-yl-2-ylidene)) bis(3-oxopropanoate) ligand (H2L) was synthesized as a potential chemotherapeutic ...
Wedelolactone Acts as Proteasome Inhibitor in Breast Cancer Cells
(MDPI, Basel, 2017)
Wedelolactone is a multi-target natural plant coumestan exhibiting cytotoxicity towards cancer cells. Although several molecular targets of wedelolactone have been recognized, the molecular mechanism of its cytotoxicity ...

(Taylor & Francis Ltd, Abingdon, 2017)
Context: Bioprospection has become a dynamic scientific field that explores novel possibilities for the implementation of natural products in medicine and pharmacy. Compared to marine species from all kingdoms, freshwater ...
Composition of Anthocyanins in Colored Grains and the Relationship of Their Non-Acylated and Acylated Derivatives
(Inst Animal Reproduction & Food Research Polish Acad Sciences Olsztyn, Olsztyn, 2019)
Colored grains are rich sources of anthocyanins that could play an important role in the prevention of various diseases associated with oxidative stress. Bearing in mind that cereals are widely grown crops, anthocyanins-rich ...
Stictic acid inhibits cell growth of human colon adenocarcinoma HT-29 cells
(Elsevier Science Bv, Amsterdam, 2017)
The growth inhibition of stictic acid, a secondary metabolite isolated from the lichen Lobaria pulmonaria (L.) Hoffm. (Lobariaceae), was evaluated in vitro on three human cell lines for the first time. The cell lines HT-29 ...
Contents of phenolics and carotenoids in tomato grown under polytunnels with different UV-transmission rates
(Tubitak Scientific & Technical Research Council Turkey, Ankara, 2017)
Tomato (Solanum lycopersicum L.) is among the economically most important vegetables in Europe, valued for its bioactive properties due to significant contents of vitamins, carotenoids, and phenolic compounds. In this ...
Influence of starting powder milling on magnetic properties of Mn-Zn ferrite
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2017)
In this paper, the influence of additional sieving and milling of starting industrial Mn-Zn powders on magnetic properties was investigated. The starting powder was milled for 60 minutes, followed by sieving through 325 ...
Investigation of zinc stannate synthesis using photoacoustic spectroscopy
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2007)
Mixtures of ZnO and SnO2 powders, with molar ratio of 2:1, were mechanically activated for 40, 80 and 160 minutes in a planetary ball mill. The resulting powders were compacted into pellets and non-isothermally sintered ...
