Determination of pyridoxine (vitamin B-6) in pharmaceuticals and urine samples using unmodified boron-doped diamond electrode
(Elsevier Science Sa, Lausanne, 2016)
Pyridoxine (vitamin B-6, VB6) was detected in pharmaceutical preparation and human urine samples by employing differential pulse voltammetry (DPV) at unmodified boron doped electrode. In Britton-Robinson buffer solution ...
Dehydroicetexanes in sediments and crude oils: Possible markers for Cupressoideae
(Elsevier, 2019)
Two previously unidentified dehydroabietane isomers were isolated from Miocene Serbian
lignite and Rhaetian (Late Triassic) coaly mudstones from South Sweden and characterized using
NMR-spectroscopy as cis- and ...
Organocatalyzed synthesis of (-)-4-epi-fagomine and the corresponding pipecolic acids
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
The enantioselective synthesis of 4-epi-fagomine was accomplished starting from dioxanone and Cbz-protected benyzlamine, in 4 steps, with 18% overall yield. The key feature of this synthetic approach is the tactical ...
Mononuclear gold(III) complexes with phenanthroline ligands as efficient inhibitors of angiogenesis: A comparative study with auranofin and sunitinib
(Elsevier Science Inc, New York, 2017)
Gold(III) complexes with 1,7- and 4,7-phenanthroline ligands, [AuCl3(1,7-phen-kappa N7)] (1) and [AuCl3(4,7-phen-kappa N4)] (2) were synthesized and structurally characterized by spectroscopic (NMR, IR and UV-vis) and ...
Assessment of antioxidant activity in Victorian marine algal extracts using high performance thin-layer chromatography and multivariate analysis
(Elsevier Science Bv, Amsterdam, 2016)
The aim of this study was to develop and validate a rapid and simple high performance thin layer chromatographic (HPTLC) method to screen for antioxidant activity in algal samples. 16 algal species were collected from local ...
Combined multivariate data analysis of high-performance thin-layer chromatography fingerprints and direct analysis in real time mass spectra for profiling of natural products like propolis
(Elsevier Science Bv, Amsterdam, 2014)
Sophisticated statistical tools are required to extract the full analytical power from high-performance thin-layer chromatography (HPTLC). Especially, the combination of HPTLC fingerprints (image) with chemometrics is ...
Quantitative structure-activity relationship analysis of substituted arylazo pyridone dyes in photocatalytic system: Experimental and theoretical study
(Elsevier Science Bv, Amsterdam, 2016)
A series of arylazo pyridone dyes was synthesized by changing the type of the substituent group in the diazo moiety, ranging from strong electron-donating to strong electron-withdrawing groups. The structural and electronic ...
5-Aryl-1H-pyrazole-3-carboxylic acids as selective inhibitors of human carbonic anhydrases IX and XII
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Inhibitory activity of a congeneric set of 23 phenyl-substituted 5-phenyl-pyrazole-3-carboxylic acids toward human carbonic anhydrase (hCA, EC 4.2.1.1) isoforms I, II, IX and XII was evaluated by a stopped-flow CO2 hydrase ...
Expression and characterization of a thermostable organic solvent-tolerant laccase from Bacillus licheniformis ATCC 9945a
(Elsevier Science Bv, Amsterdam, 2016)
Bacterial laccases have proven advantages over fungal and plant counterparts in terms of wider pH optimum, higher stability and broader biocatalytic scope. In this work, Bacillus licheniformis ATCC 9945a laccase is produced ...
Preparation, characterization and photocatalytic activity of lanthanum and vanadium co-doped mesoporous TiO2 for azo-dye degradation
(Elsevier Science Bv, Amsterdam, 2013)
Titanium dioxide photocatalysts co-doped with lanthanum and vanadium were prepared by a facile microwave-assisted hydrothermal method and characterized by XRD, SEM, N-2 physisorption at 77 K and DRS. The characterization ...
