Protolytic equilibria in homogeneous and heterogeneous systems of ketoconazole and its direct spectrophotometric determination in tablets / Protolitičke ravnoteže u homogenom i heterogenom sistemu ketokonazola i njegovo direktno spektrofotometrijsko određivanje u tabletama
(Srpsko hemijsko društvo, Beograd, 2005)
The acid-base equilibria of a diprotic, slightly hydrosoluble base ketoconazole were studied in homogeneous and heterogeneous water systems. The determinations were performed at 25ºC at a constant ionic strength of M(NaCl). ...
3D-QSAR study of adenosine 5'-phosphosulfate (APS) analouges as ligands for APS reductase / 3D-QSAR студија аналога аденозин 5'-фосфосулфата (APS) као лиганда за APS редуктазу
(Belgrade: Serbian Chemical Society, 2021)
Metabolism of sulfur (sulfur assimilation pathway, SAP) is one of the key pathways for the pathogenesis and survival of persistant bacteria, such as Mycobacterium tuberculosis (Mtb), in the latent period. Adenosine ...
Acid-base equilibria of the Zn(II) and Fe(III) complexes with condensation products of 2-acetylpyridine and the dihydrazide of oxalic and malonic acid / Kiselinsko-bazne ravnoteže kompleksa Fe(III) i Zn(II) sa kondenzacionim derivatima 2-acetilpiridina i hidrazida oksalne, odnosno malonske kiseline
(Srpsko hemijsko društvo, Beograd, 2009)
Acid-base equilibria of Zn(II) and Fe(III) complexes with N',N'2-bis- [(1E)-1-(2-pyridyl)ethylidene]ethanedihydrazide (ligand L1) and N',N'2-bis[(1E)- -1-(2-pyridyl)ethylidene]propanedihydrazide (ligand L2), i.e., ...
Kinetic study of the reaction between sodium chloroacetate and potassium ethylxanthogenate / Kinetička ispitivanja reakcije između natrijum-hloracetata i kalijum-etil-ksantata
(Srpsko hemijsko društvo, Beograd, 2007)
The reaction kinetics of the synthesis of sodium ethyl xanthogeneacetate from potassium ethylxanthogenate and sodium chloroacetate in distilled water as the reaction medium at 25, 30, 35 and 40°C, were investigated. The ...
Synthesis, characterization and antimicrobial activity of the isothiocyanato Fe(III) Girard's T hydrazone complex
(Srpsko hemijsko društvo, Beograd, 2018)
The isothiocyanato Fe(III) complex with (E)-N, N, N-trimethyl-2-oxo- 2-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)ethan-1-aminium was synthesized and characterized by elemental analysis, IR spectroscopy and X-ray analysis. ...
Spectrophotometric investigation of the uranyl-phenylephrine system / Spektrofotometrijsko ispitivanje uranil-fenilefrin sistema
(Srpsko hemijsko društvo, Beograd, 2007)
Using spectrophotometric methods and pH-metric measurements, it was found that the uranyl ion and phenylephrine form a 1:2 complex in the pH region 2.50-4.25 with two absorption maxima at 314.2 nm and 340.6 nm. The ...
Spectrophotometric determination of thioctic (α-lipoic) acid in water and pharmaceutical preparations / Spektrofotometrijsko određivanje tioktinske kiseline u vodi i farmaceutskim preparatima
(Srpsko hemijsko društvo, Beograd, 2007)
A spectrophotometric method is described for the assay of thioctic acid. The method is based on the reaction between the drug and palladium(II) chloride. In this reaction, a yellow-colored, water soluble product with a 1:1 ...
