To develop an efficient and reusable heterogeneous Fenton-like catalyst is a great challenge for its application in practical water treatment. Effective oxygen vacancy (OVs)-promoted Fe2O3-CeO2 catalyst was prepared by a sol-gel method, and applied in the heterogeneous Fenton-like reaction of th...
This paper describes the application of poly (ethylene glycol dimethacrylate-N-methacryloyl-L-tryptophane methyl ester) [p(EGDMA-MATrp)] microspheres as an affinity sorbent for the SPE (solid phase extraction) cleanup of sulfamerazine (SMR) from food samples of animal origin before high performa...
A great number of antimicrobials belonging to fluoroquinolones and sulfonamides families are used in the livestock industries. These compounds are not completely absorbed, by reaching agricultural soils and whereas maintaining their pharmacological activity. Due to this, a theoretical and electr...
Publisher SummaryThe 11β-hydroxysteroid dehydrogenase isozymes (11β-HSDs) are members of the short-chain dehydrogenase/reductase (SDR) family, a functionally heterogeneous protein family comprising the majority of known hydroxysteroid dehydrogenases. The 11β-HSDs are microsomal enzymes cataly...
A systematic computational study was carried out to characterize the hydrogen bond, HB, interactions of sulfabenzamide crystal structure by DFT calculations of electric field gradient, EFG, tensors at the sites of 14N, 17O, and 2H nuclei. The computations were performed with the B3LYP and B3PW91...
Herein, hydroxypropyl-beta-cyclodextrin (HPβCD) inclusion complex (IC) of a hydrophobic drug, sulfisoxazole (SFS) was incorporated in hydroxypropyl cellulose (HPC) nanofibers (HPC/SFS/HPβCD-IC-NF) via electrospinning. SFS/HPβCD-IC was characterized by DSC to investigate the formation of inclu...
The present work describes the synthesis, structural characterization and antibacterial assays of two silver(I) complexes with the sulfa drugs sulfisoxazole (SIZH) and sulfadimethoxine (SDMXH). Chemical analyses and high resolution mass spectrometric studies led to 1:1 metal/ligand compositions,...
In recent years, numerous studies have been concentrated on enhancing the efficiency of SO4− based advanced oxidation processes (AOPs) on eliminating contaminants. In this study, an efficacious heterogeneous copper-cobalt catalyst (Cu0.39Co1.01O4.57) was synthesized by a simple coprecipitation m...
Graphite and graphene electrodes were prepared by using pure graphite as precursor. The electrode materials were characterized by a scanning electron microscope (SEM), X-ray diffraction (XRD) and cyclic voltammetry (CV) measurements. The electro-catalytic activity for degradation of sulfisoxazol...
Sulfisoxazole (SFX) is still used in combination with trimethoprim in cattle despite adverse drug reactions (e.g., urolithiasis). Recently, SFX is known to be a promising repositioned drug candidate for pulmonary hypertension and cancer. We developed a simultaneous determination method of SFX an...
As robust polymeric catalysts, graphitic carbon nitride (g-C3N4) has been known to have great application potential in environmental remediation. However, the mechanisms in the photo-assisted catalytic processes during the reduction or oxidation of pollutants are still difficult to discern and t...
In this study, our aim was to develop solid drug-cyclodextrin inclusion complex system having nanofibrous morphology in order to have fast-dissolving property and enhanced water-solubility of poorly water-soluble drug. Here, we prepared a highly concentrated aqueous solution of inclusion complex...
Sulfisoxazole is a sulfonamide antibacterial agent that is rapidly absorbed and short-acting. Sulfisoxazole is used for the treatment of acute urinary tract infections. Because sulfisoxazole does not penetrate cells and pass barriers as well as most sulfonamides, it may not always be effective a...
N1-acetyl sulfisoxazole (N1AS), a dihydropteroate synthase inhibitor is known to be biotransformed primarily to sulfisoxazole, partly to N4-acetyl sulfisoxazole (N4AS), and likely also to diacetyl sulfisoxazole (DAS) and other compounds. Although its clinical use has been limited due to urolithi...
Dark red coloured single crystals of [cis-Co(en)2(N3)2] C6H3ClNO5S·H2O were obtained by slowly mixing the separately dissolved cis-diazidobis(ethylenediamine)cobalt(III) nitrate with sodium 2-chloro,5-nitrobenzenesulphonate in aqueous medium in 1:1 molar ratio. The complex salt was characterize...
The aim of the present work was to investigate the geometries, relative stabilities and electronic charge distributions of the different conformers of the 2-oxazolidinone analogues of pilocarpine and its dimethylated derivative pilocarpidine. Calculations were performed at three levels. The most...
Electrochemical measurement methods are suitable for examining the hydrolysis and reactivity of chloramine T. The individual species can be separated by means of capillary electrophoresis. Voltammetrical methods make it possible to judge selectively on the oxidation efficiency of individual subs...
The kinetics of oxidation of α-amino acids (AAs) by chloramine-T (CAT) using β-cyclodextrin (BCD) as catalyst was studied in aqueous sodium hydroxide medium at 313 K. The kinetics of reactions was fractional-order with respect to [amino acids] and [β-cyclodextrin]. First-order with respect to...
A facile and expedient one pot synthesis of 8-chloro-[1,2,4]triazolo[4,3-a]pyrazine derivatives from 2-chloro-3-hydrazinylpyrazine and aldehydes is described using chloramine T trihydrate as a safe and convenient electrocyclisation (oxidising) agent. The presence of the chloro group on pyrazine ...
SummaryChloramine T (CAT) and monochloramine (NH2Cl) are active chlorine compounds and well-known biocides. CAT has stronger oxidative activity than NH2Cl, which is a smaller, more lipophilic molecule. The question arises whether lower oxidative activity can be compensated by higher lipophilicit...
