Synthesis of the dioxomolybdenum(VI) complexes [MoO2(L3OMe)(EtOH)] (1), [MoO2(L4OMe)(EtOH)] (2) and [MoO2(LH)(EtOH)] (3) dioxotungsten(VI) [WO2(L3OMe)(EtOH)] (4), [WO2(L4OMe)(EtOH)] (5) [WO2(LH)]n (6a) was carried out using [MO2(C5H7O2)2] (M = Mo or W) corresponding aroylhydrazone ligand H2LR (3-methoxysalicylaldehyde 4-hydroxybenzhydrazone (H2L3OMe), 4-methoxysalicylaldehyde (H2L4OMe), salicylaldehyde (H2LH) in ethanol. Compounds obtained upon heating mononuclear acetonitrile...
Pyridoxal hydrazonato molybdenum(VI) complexes were prepared by the reaction of corresponding hydrazone (H2L1 = pyridoxal isonicotinic acid hydrazone, H2L2 benzhydrazone, H2L3 4-hydroxy benzhydrazone) and [MoO2(acac)2] under appropriate conditions. The can be classified into three categories: mononuclear [MoO2(L1–3)(MeOH)], polynuclear [MoO2(L1–3)]n hybrid organic–inorganic compounds with Lindqvist polyoxomolybdate [MoO2(HL1–3)]2Mo6O19. A unique example a cationic polymer assembly anions is...
Macrolide antibiotics, such as azithromycin and erythromycin, are in widespread use for the treatment of bacterial infections. Macrolides taken up excreted mainly by bile. Additionally, they have been implicated biliary system diseases to modify excretion other drugs through Despite mounting evidence interplay between macrolide antibiotics bile acids, molecular details this interaction remain unknown. Herein, we show NMR measurements that macrolides directly bind acid micelles. The topology...
Brewer's spent grain (BSG) is an important secondary raw material that provides a readily available natural source of nutraceuticals. It finds its largest application as animal feed and part the human diet, while future perspective predicts in production value-added products. In order to investigate sustainable BSG treatment method, two samples (BSG1 BSG2) were evaluated substrates for hydrolytic (xylanase, β-glucosidase cellulase) lignolytic enzymes (laccase, manganese peroxidase lignin...
Interactions of macrolide antibiotics with biological membranes contribute to their bioavailability but are also involved in the formation phospholipidosis, which is caused by inhibition phospholipase A(1) activity. We determined interaction strength and localization membrane-mimetics. Macrolides bind membrane-mimetics positively charged amino groups being close micelle surface thereby protect lipids from degraded rather than inhibiting enzyme.
The development of a quantitative in-line Raman spectroscopic method for the monitoring active pharmaceutical ingredient, omeprazole synthesis reaction, and characterization reaction components is described. In-line was performed both with Fourier transform dispersive spectrometers. Prior to monitoring, were characterized off-line by means NMR spectroscopy, in solution solid state. To unequivocally confirm presence each component mixture, state art LC-SPE/NMR methodology also used. Owing its...
An approach that combines NMR spectroscopy and inductively coupled plasma mass spectrometry (ICP-MS) advanced tensor decomposition algorithms with state-of-the-art deep learning procedures was applied for the classification of Croatian continental sparkling wines by their geographical origin. It has been demonstrated complex high-dimensional or ICP-MS data cannot be classified higher-order alone. Extension procedure reinforcement resulted in an exquisite neural network predictive model...
Deprotonation of the mononuclear aroylhydrazonato complexes [MoO<sub>2</sub>(HL<sup>R</sup>)(MeOH)]Cl was performed by different methods.
The catalytic performances (activity and selectivity) of the mononuclear dioxotungsten(<sc>vi</sc>) complexes [WO<sub>2</sub>(L<sup>R</sup>)(D)] towards alkene epoxidation by<italic>tert</italic>-butyl hydroperoxide (TBHP) were investigated under different conditions.
NMR spectroscopy in combination with statistical methods was used to study vacuum residues and gas oils from 32 crude of different origin.Two chemometric metodes were applied.Firstly, principal component analysis on complete spectra perform classification samples clear distinction between light heavy obtained.To quantitatively predict the composition asphaltenes, regression models using areas resonance signals spaned by 11 frequency bins 1 H build.The first 5 components accounted for more...
