Production and characterization of extracellular polymeric substances (EPS) generated by a carbofuran degrading strain Cupriavidus sp. ISTL7

The present study demonstrates EPS production by Cupriavidus sp. ISTL7 along with its capability to remediate a toxic carbamate pesticide, carbofuran. The strain ISTL7 efficiently degraded approximately 98% of carbofuran (400 ppm) within 96 h. GC?MS analysis showed catabolic metabolites of degradation which included carbofuran-7-phenol, methylamine, 2-hydroxy-3-(3-methylpropan-2-ol)benzene-N-methyl-carbamate etc. EPS production from the mineral medium supplemented with carbofuran was observed to be 3.112 ¡À 0.3682 g L?1. FTIR confirmed its carbohydrate composition and the monomeric sugars: glucose, xylose, sorbitol and fructose were identified by GC?MS analysis. The toxic potential of degradation experiment and the produced EPS was evaluated on HepG2 (mammalian liver cell line). The cytotoxicity of carbofuran was reduced upon bacterial degradation and the formed EPS was found to be non-toxic as inferred from percentage cell viability. The present research can possibly influence the development strategies of biological remediation.

Structure-affinity relationship study on N-[4-(4-arylpiperazin-1-yl)butyl]arylcarboxamides as potent and selective dopamine D3 receptor ligands

The benzamide PB12 (N- [2-[4-(4-chlorophenyl)piperazin-1-yl] ethyl]-3-methoxybenzamide) (1), already reported as potent and selective dopamine D4 receptor ligand, has been modified searching for structural features that could lead to D3 receptor affinity. Changes in the aromatic ring linked to N-1 piperazine ring led to the identification of 2-methoxyphenyl and 2,3-dichlorophenyl derivatives (compounds 6 and 13) displaying moderate D3 affinity (Ki = 145 and 31 nM, respectively). Intermediate alkyl chain elongation in compounds 1, 6, and 13 improved binding affinity for the D3 receptor and decreased the D4 affinity (compounds 18-26). Among these latter compounds, the N-[4-[4-(2,3-dichlorophenyl)piperazin-1-yl]butyl]-3- methoxybenzamide (19) was further modified with the replacement or of the 2,3-dichlorophenyl moiety (compounds 27-30) or of the 3-methoxyphenyl ring (compounds 31-41). In this way, we identified several high-affinity D3 ligands (0.13 nM < Ki's < 4.97 nM) endowed with high selectivity over D2, D4, 5-HT1A, and alpha1 receptors. In addition, N-[4-[4-(2,3-dimethylphenyl)- piperazin-1-yl]butyl]-3-methoxybenzamide (27) and N-[4-[4-(2,3-dichlorophenyl)piperazin-1-yl]- butyl]-7-methoxy-2-benzofurancarboxamide (41) appear to be valuable candidates for positron emission tomography (PET) because of their affinity values, lipophilicity properties, and liability of 11C labeling in the O-methyl position. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 496-41-3, help many people in the next few years.496-41-3

A highly selective diarylethene chemosensor for dual channel recognition of CN? and Zn2+ and its application

A novel diarylethene chemosensor comprising 3-aminobenzofuran-2-carboxamide Schiff base (1O) was synthesized and the photophysical and sensing behaviors of 1O were further investigated. Importantly, the introduction of electron-withdrawing group to 1O made the sensor an efficient tool for detection of toxic cyanide even in the presence of other plausible interfering anions including fluoride and acetate. In particular, addition of CN? to 1O visibly changes the color from colorless to orange-red, which can be observed by the naked eye. Apart from this, it also exhibited an outstanding fluorometric sensing toward Zn2+ with high selectivity and sensitivity. Moreover, the remarkable spectral responses of the devised sensor prompted us to fabricate molecular logic circuit. Furthermore, the sensor was successfully applied to the detection of CN? on test strips and silica coated microslides, and the methods were very simple to operate without resorting to any spectroscopic instrumentation. In addition, the 1O can also effectively detect CN? and Zn2+ in actual water samples.

Synthesis of Perfluoroalkyl-Substituted Vinylcyclopropanes by Way of Enhanced Neighboring Group Participation

A simple, high yielding, two-step, one-pot protocol for the preparation of trifluoromethyl-substituted vinylcyclopropanes from alpha-CF3 homoallyl alcohols is disclosed. Destabilization of the cationic intermediate by the electron-withdrawing CF3 group greatly enhances neighboring group participation of the alkene, allowing ring closure to predominate. The reaction can be extended to the difluoromethyl and pentafluoroethyl group, enabling the preparation of a diverse array of fluoroalkyl-substituted vinylcyclopropanes. A diverse array of fluoroalkyl-substituted vinylcyclopropanes are prepared in a simple, high-yielding, two-step, one-pot protocol by means of cationic ring-closure.

On-water chemistry: Copper-catalyzed straightforward synthesis of benzo[b]furan derivatives in neat water

A more sustainable protocol leading to 2-alkyl- or 2-aryl-substituted benzo[b]furans is reported, involving a copper-TMEDA complex which catalyzes the transformation of readily available ketone derivatives into the corresponding benzofurans in good to excellent yields. The reaction is accomplished using water as the solvent without organic cosolvents, and one example of catalyst reutilization is also presented.

Bio-based nickel alginate and copper alginate films with excellent flame retardancy: Preparation, flammability and thermal degradation behavior

A bio-based nickel alginate film and copper alginate film were prepared via a facile ion exchange and casting approach. Their flame retardancy, thermal degradation and pyrolysis behavior, and thermal degradation mechanism were investigated systematically by the limiting oxygen index (LOI), vertical burning (UL-94), microscale combustion calorimetry (MCC), thermogravimetric analysis (TGA), thermogravimetric analyzer coupled with Fourier transform infrared analysis (TG-FTIR) and pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS). It was shown that the nickel alginate film had a much higher LOI value (50.0%) than those of the sodium alginate film (24.5%) and copper alginate film (23.0%). Moreover, the nickel alginate film passed the UL-94 V-0 rating, while the sodium alginate film and copper alginate film showed no classification. Importantly, the peak of heat release rate (PHRR) of the nickel alginate film in the MCC test was much lower than those of the copper alginate film and sodium alginate film. This indicated that the introduction of nickel ions decreased the release of combustible gases. TGA results showed that the addition of copper ions and nickel ions accelerated the thermal degradation of alginates and changed the thermal degradation mechanism of the alginates. TG-FTIR and Py-GC-MS results indicated that the pyrolysis of copper alginate and nickel alginate produced much less flammable products than that of sodium alginate in the whole thermal degradation process. Finally, a possible degradation mechanism for copper alginate and nickel alginate was proposed. The results of our study provide useful information for understanding the flame retardancy mechanism of alginate as well as for designing bio-based materials with excellent fire retardancy.

Direct conversion of glycerol into bio-oil via hydrotreatment using supported metal catalysts

Hydrotreatment of glycerol (a byproduct of bio-diesel production) was conducted in the presence of a number of different supported metal catalysts at a temperature of 300 C under 5 MPa initial pressure of H2. The bio-oil products were comprehensively characterized to determine their physical/chemical properties. Experiments with supported catalyst metals revealed a positive correlation between support acidity and bio-oil yield. It was determined that MoCoP is the most effective combination of catalyst metals, and the bio-oil yield from hydro-treatment of glycerol with the MoCoP catalysts is strongly dependent on the support materials, following the trend of MgO < AC < Al2O3 < zeolite. With the MoCoP/zeolite catalyst, a maximum yield of ?40 wt.% bio-oil, and >90% glycerol conversion was achieved for 60 min reaction. The volatile components of the bio-oil were found to consist mostly of substituted phenols and ketones in the C6-C9 range. The bio-oils obtained had a maximum HHV of 33 MJ/kg and the majority (?95%) of the compounds present was found to have boiling points lower than 165 C, making these bio-oils potential oxygenated fuel additives.
