Hydroxyl radical is a highly reactive oxygen species and can be used to oxidize many pollutants and toxic organic compounds. 2-Anthraquinone sulfonate (2-AQS) was found capable of producing hydroxyl radicals under UVA exposure. In this study, the photo-induced oxidative degradation of methylene ...

Sodium 9,10-anthraquinone-2-sulfonate (AQS) binds to the double helical DNA with a high affinity, as deduced from the absorption and fluorescence spectral data. The results of absorption spectra, KI quenching studies, competitive binding studies, and thermal denaturation experiments suggested th...

Geobacter sulfurreducens and anthraquinone-2-sulfonate (AQS) were used suspended and immobilized in barium alginate during the biotransformation of 4-nitrophenol (4-NP). The assays were conducted at different concentrations of 4-NP (50–400 mg/L) and AQS, either in suspended (0–400 μM) or immo...

Anthraquinone-2-sulfonate (AQS) was employed in humus substitutes to evaluate the effects and influencing factors of U(VI) reduction by Shewanella oneidensis MR-1 (S. oneidensis MR-1) under anaerobic condition. The removal rate of U(VI) at 30 °C reaches 99.0% afterd 96 h with the pH value of 7....

In order to enhance the biodecolorization rate and avoid the wash-out problems of redox mediators in continuous systems such as a fluidized bed reactor, polyvinyl alcohol (PVA) beads modified with N-containing function groups were investigated and employed as a new sodium anthraquinone-2-sulfona...

Three triorganotin(IV) complexes of composition R3SnLH (R = Me, Bu and Ph and LH = 2-[(E)-2-(4-hydroxy-3,5-dimethylphenyl)-1-diazenyl]benzoate) have been synthesized and characterized by 1H, 13C, 119Sn NMR, and IR spectroscopic techniques in combination with elemental analysis. The crystal struc...

Melanin protects the skin from harmful environmental factors such as UV light. However, excessive melanin production induces hyperpigmentation. Previously, N-(3,5-dimethylphenyl)-3-methoxybenzamide (A3B5), a biaryl amide derivative, was identified for its ability to inhibit melanin production. H...

N-(2,4-Dimethylphenyl)-2,2-dichloroacetamide (24DMPA) and N-(3,5-dimethylphenyl)-2,2-dichloroacetamide (35DMPA) of the configuration XyC6H5−yNHCOCHCl2 (where, X = CH3 and y = 2) were synthesised and an extensive spectroscopic investigations have been carried out. The ab initio and DFT studies we...

A new chiral monolithic column for enantiomer separation in capillary LC was successfully prepared by coating the chiral selector cellulose tris(3,5-dimethylphenyl carbamate) onto an organic polymer. This polymer, with optimized porous properties, has been prepared in situ in pretreated fused-si...

Most of the human bacterial infections are associated with the biofilm formation and the natural tolerance of biofilms to antibiotics challenges treatment. Because of their low immunity, cancer patients are especially susceptible to bacterial infections. Compounds with anti-biofilm activity coul...

A series of 7H-pyrrolo[2,3-d]pyrimidine derivatives were designed and synthesized as reversible BTK inhibitors, and evaluated their kinase selectivity, anti-proliferation against the B-cell lymphoma cell lines (Ramos, Jeko-1) and cell line BTK enhanced (Daudi) in vitro. Among them, compound 28a ...

A series of 2-oxo-3, 4-dihydropyrimido[4,5-d]-pyrimidinyl derivatives were designed and synthesized as new irreversible inhibitors of the FGFR family. One of the most promising compounds 2l potently inhibited FGFR1/2/3 with IC50 values of 1.06, 0.84 and 5.38 nM, respectively, whereas its potency...

The purpose of the study was to gain insight into epidemiological aspects of soft tissue sarcomas (STS), based on the population-based cancer registry of the Comprehensive Cancer Center North-Netherlands (CCCN), and to provide data for the development of future STS clinical trials. 456 primary S...

BackgroundIt has been postulated that mitral valve repair in the elderly does not confer short-term benefits over mitral valve replacement with complete preservation of the chordal apparatus. Our purpose was to test this hypothesis using data from The Society of Thoracic Surgeons Adult Cardiac S...

Third-generation synchrotrons and high-resolution electron spectrometers coupled with modern theoretical techniques for molecular structure calculations have opened opportunities for measuring carbon 1s ionization energies in a large variety of complex molecules. Recent studies have provided new...

A series of periodic mesoporous propylsulfonic/arenesulfonic acid and titanium bi-functionalized ethyl/phenyl-bridged organosilica hybrid catalysts, Pr/ArSO3H-Si(Et/Ph)Si-Ti, with controllable Ti loadings are prepared by a nonionic surfactant-templated sol–gel co-condensation route under acidic...

Fourier transform mid-infrared (MID-FTIR) spectroscopy coupled with chemometric analysis was used to identify and quantify coumarin (CMR) and ethyl vanillin (EVA) adulterations in pure vanilla extracts. Forty samples adulterated with CMR (0.25–10 ppm) and forty with EVA (0.25–10%) were prepare...
