A new calix[4]arene thiourea derivative bearing a benzothiazolyl moiety (L) was synthetized and characterized by single crystal X-ray, NMR and ESI-TOF. The binding ability of the bifunctional receptor towards several ions was investigated in acetonitrile by means of UV–Visible and NMR spectrosc...
The present study describes the synthesis, characterization, DNA binding and in vitro biological evaluation of ferrocene-enhanced thioureas. The new complexes (N1–N6) were prepared by reacting ferrocenyl anilines (A-B) with freshly prepared isothiocyanates in dry acetone. A crystallographic stu...
Three different single crystals formed between the 1-(diaminomethylene)thiourea and citric acid from water solution depending on the concentration and the molar composition of 1-(diaminomethylene)thiourea to citric acid, i.e. 1-(diaminomethylene)thiouron-1-ium citrate monohydrate (1), tris(1-(di...
The adsorption of thiourea at the interface the mercury/1 mol dm−3 NaClO4 and the mercury/1 mol dm−3 HClO4 was studied in the function of the electrode potential and the adsorbate concentration. In the study was used, the experimental data obtained from the measurement of differential capacity o...
The synthesis of 2,3:4,5-dianhydro-1,6-dibromo-1,6-dideoxy-D-iditol and -galactitol and some of their derivatives, starting from 1,6-dibromo-1,6-dideoxy-3,4-O-isopropylidene-D-mannitol, is described. The galactitol derivative was formed via 3,5-di-O-acetyl-1,6-dibromo-1,6-dideoxy-D-mannitol, an ...
A new, four-step synthesis of 2,5:3,6-dianhydro-1-deoxy-d-glucitol 16 was worked out, starting from 1,6-dibromo-1,6-dideoxy-d-mannitol. Compound 16 was converted into different 4-O-acyl derivatives, the 3,6-anhydro rings of which where opened with hydrogen bromide, yielding the corresponding 6-b...
Refrigeration delayed the ripening of ‘Nanguo’ pears (Pyrusussuriensis Maxim.), but the aroma of the pears was apt to fade when the fruit was transferred to room temperature. ATP treatment, in which the pears were exposed to 1 mol/L ATP for 2 h on the day of removal from refrigeration for 150 ...
Short-term 48, 72 and 96-h aquatic toxicity tests were conducted to evaluate the acute toxicity of eight fluorinated acids to the cladoceran, Daphnia magna, the green alga, Pseudokirchneriella subcapitata, and the rainbow trout, Oncorhynchus mykiss or the fathead minnow, Pimephales promelas. The...
Concerns over sustained availability of fossil resources along with environmental impact of their use have stimulated the development of alternative methods for fuel and chemical production from renewable resources. In this work, we present a new approach to produce α,β-unsaturated carboxylic ...
Effects of carbon chain length, carbon chain isomerism, CC double bonds number on fatty acid adsorption on FAP (0 0 1) surface have been investigated based on DFT. The results revealed that fatty acid collector can form stable adsorption configuration at Ca1 (surf) site. Chemical adsorption was ...
The effects of a novel synthetic fatty acid derivative (TEI-8005: (7E)-8-(2-naphthyl)-5,6-trams-5,6-methano-7-octenoic acid) on arachidonic acid metabolism in some cultured cells were studied. The compound significantly stimulated prostaglandin,(especially prostacyclin) biosynthesis in cultured ...
Cetirizine (2-(2-(4-(4-chlorophenyl)phenylmethyl)-1-piperazinyl)ethoxy)acetic acid dihydrochloride) (Fig 1) is the principal human metabolite of hydroxyzine (Fig 2), a member of the piperazine class of antihistamines. It is a selective H1 histamine receptor antagonist, which has been shown to be...
IR, 1H NMR and mass spectrometric studies showed that cetirizine dihydrochloride interacted strongly with diclofenac sodium, even when the latter was metal bound, forming high molecular weight stable adducts. These new formations were unaffected by the possible steric constraints that may exist ...
Established vineyard soils may have high copper (Cu) contents due to the ongoing foliar applications of copper-based fungicides. In viticulture, the replacement of old vineyards with new vines is common practice, however, limited by Cu excess in soil and its toxicity to young grapevines. The app...
A highly selective and sensitive phosphate sensor has been fabricated by constructing a crystal disk consisting of variable mixtures of aluminium powder (Al), aluminium phosphate (AlPO4) and powdered copper (Cu). The membrane sensor exhibits linear potential response in the concentration range o...
ObjectiveTo investigate the effect of poly-acrylic acid (PAA) copper iodide (CuI) adhesives on bond degradation, tensile strength, and biocompatibility.
The present study evaluated an extracellular, novel biopolymer produced by Acinetobacter haemolyticus MG606 for its physicochemical properties and phosphate binding mechanism. The exobiopolymer (EBP) was characterized to be majorly polysaccharide in nature consisting of 48.9 kDa heteropolysaccha...
A polyaminosaccharide (chitosan, CS) and an aminosaccharide (d-galactosamine, GalN) were integrated together via hydrothermal assembly to obtain a bis-aminosaccharides composite (CS-GalN), and a novel and facile chiral sensing platform based on CS-GalN modified glassy carbon electrode (CS-GalN/G...
Fifty years ago, when this journal was founded, organometallic chemists could not have imagined that common small molecules such as dinitrogen and especially dihydrogen could function as ligands. Dihydrogen has long been vital in catalytic processes such as hydrogenation and conversions of organ...
