Ozonation of the dye Reactive Red 239 and biodegradation of ozonation products in a moving-bed biofilm reactor: Revealing reaction products and degradation pathways

The ozonation of the azo dye Reactive Red 239 (RR 239) was investigated in a bench-scale reactor. Decolorization and organic matter removal were monitored in batch assays. The toxicity of the dye and its ozonation products to the test-organism Aliivibrio fischeri was also assessed. Identification of ozonation products was performed using analytical techniques (GC-MSD and high resolution mass spectrometry). Ozonated and non-ozonated dye solutions were supplemented with organic matter (glucose) and nutrients sources and subjected to biological treatment in a moving-bed biofilm reactor (MBBR). Five experimental runs were conducted, varying the influent characteristics and monitoring organic matter removal and nitrification performance. Identification of residual compounds in the effluent was also performed. Color was very rapidly removed by ozonation, but the degree of mineralization achieved was rather low. Moreover, toxicity was completely removed after 4 min of ozone reaction. Based on the ozonation products, a two-way mechanism was proposed for the degradation of RR 239 by ozone. Further biological treatment in the MBBR revealed that the removal of organic matter (evaluated as COD) was not affected by the ozonation products. However, nitrification efficiency dropped significantly when the dye or the ozonated dye was fed to the bioreactor. Furthermore, inhibition of nitrite oxidizers resulted in partial nitrification and consequent accumulation of nitrite, which consisted of the main oxidized nitrogen specie in the reactor effluent. The identification of compounds resulting from the ozonation and biological treatment steps suggests that the partial inhibition of nitrifying organisms was possibly caused by triazine- and benzofuran-related organic compounds. Nevertheless, their adverse effect on nitrification was found to be reversible and practically ceased once these compounds were removed from the influent. Overall, the results revealed that the combination of ozonation and MBBR for the treatment of azo dye containing-wastewaters is promising but the ozone-based process should be optimized in order to enable the degradation of compounds inhibiting nitrification.

Synthesis, characterization and photophysical studies on novel benzofuran-3-acetic acid hydrazide derivatives by solvatochromic and computational methods

In the present studies, synthesis of two novel benzofuran-3-acetic acid hydrazide derivatives namely, (6-methyl-benzofuran-3-yl)-acetic acid hydrazide [6MLBH] and (6-methoxy-benzofuran-3-yl)-acetic acid hydrazide [6MOBH] are reported. The probes are characterized by IR, H-1-NMR, C-13-NMR and mass spectral methods. The absorption and fluorescence maxima of novel derivatives 6MLBH and 6MOBH are determined for different solvents of varying polarity and the solvatochromic behavior and dipole moments are investigated. Stoke’s shift exhibits a red shift with increase in solvent polarity for both the probe molecules indicating a pi ->pi* transition. The ground state dipole moment (mu g) of both the molecules in gaseous phase is estimated from ab initio computations by using Gaussian 09 W software and also from solvatochromic method and the results are compared. Further, the ground state dipole moments of the probe molecules in different solvents were also estimated theoretically by using the integral equation formalism of polarizable continuum model (IEF-PCM). By using solvatochromic correlations like Lippert’s, Bakhshiev’s, Kawski-Chamma-Viallet’s and solvent polarity parameter (E-T(N)), the excited state dipole moments (mu(e)) are determined. Results show that, the excited state dipole moments (mu(e)) are higher than the ground state dipole moments (mu g) and suggest that, the probe molecules 6MLBH and 6MOBH are more polar in the excited state. The HOMO-LUMO energy gaps computed from density functional theory (DFT) and from absorption threshold wavelengths are found to be in agreement and also support intramolecular charge transfer (ICT). Using HOMO-LUMO energies, the chemical hardness (eta) of the molecules are determined and the chemical stability is discussed. Further, using DFT molecular electrostatic potential (MESP) plots, the electrophilic site and nucleophilic site which are useful in photochemical reactions were identified. The various types of interactions present between the solute-solvent were analyzed by multiple linear regression analysis using Catalan parameters. The preliminary observations and results suggest that, the probe molecules 6MLBH and 6MOBH can be considered as potential candidates for luminescence materials, fluorescent probes and for designing non-linear optical materials in future.

Terpolymer Strategy toward High-Efficiency Polymer Solar Cells: Integrating Symmetric Benzodithiophene and Asymmetrical Thieno[2,3-f]benzofuran Segments

While a large number of terpolymers have been developed for polymer solar cells, very few studies have directly focused on the rational selection of the third component to balance the miscibility and crystallinity for forming the desired morphology, and universal terpolymer strategies for preparing different donor/acceptor systems are lacking. Herein, we employ a new strategy involving the integration of benzodithiophene (BDT) and thieno [2,3-f ]benzofuran (TBF) segments to construct a series of terpolymer donors, and a profound influence on the crystallinity and miscibility of the blend films as well as on the ultimate device performance is observed. Incorporating highly crystalline TBF segments into a low-crystalline BDT-based alternating copolymer can not only increase the order of the microstructure, conserve the favorable face-on orientation, and promote the formation of proper phase-separation features but also generate high exciton dissociation and suppress charge recombination. This strategy was successfully applied in the reported J52 system and provided a remarkable 2-fold boost in performance. Finally, competitive power conversion efficiencies of 11.9, 12.4, and 12.2% accompanied by high fill factors of 73, 71, and 76% were recorded for TBFC150-FTAZ/ITIC-, TBFC150-BDD/ITIC-, and TBFC150-BDD/IDIC-C4Ph-based devices, respectively, via the above terpolymer strategy. Thus, our discovery provides a promising and innovative method for finely controlling the microstructure of heterojunctions for designing high-performance terpolymers.

Potential Moracin M Prodrugs Strongly Attenuate Airway Inflammation In Vivo

This study aims to develop new potential therapeutic moracin M prodrugs acting on lung inflammatory disorders. Potential moracin M prodrugs (KW01-KW07) were chemically synthesized to obtain potent orally active derivatives, and their pharmacological activities against lung inflammation were, for the first time, examined in vivo using lipopolysaccharide (LPS)-induced acute lung injury model. In addition, the metabolism of KVV02 was also investigated using microsomal stability test and pharmacokinetic study in rats. When orally administered, some of these compounds (30 mg/kg) showed higher inhibitory action against LPSinduced lung inflammation in mice compared to moracin M. Of them, 2-(3,5-bis((dimethylcarbamoyl)oxy)phenyl)benzofuran-6-yl acetate (KVV02) showed potent and dose-dependent inhibitory effect on the same animal model of lung inflammation at 1, 3, and 10 mg/kg. This compound at 10 mg/kg also significantly reduced IL-1 beta concentration in the bronchoalveolar lavage fluid of the inflamed-lungs. KVV02 was rapidly metabolized to 5-(6-hydroxybenzofuran-2-yl)-1,3-phenylene bis(dimethylcarbamate) (KW06) and moracin M when it was incubated with rat serum and liver microsome as expected. When KVV02 was administered to rats via intravenous or oral route, KVV06 was detected in the serum as a metabolite. Thus, it is concluded that KVV02 has potent inhibitory action against LPS-induced lung inflammation. It could behave as a potential prodrug of moracin M to effectively treat lung inflammatory disorders.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 14400-67-0. Computed Properties of C6H8O2.

Psoralen inhibits malignant proliferation and induces apoptosis through triggering endoplasmic reticulum stress in human SMMC7721 hepatoma cells

BackgroundPsoralen is a coumarin-like and coumarin-related benzofuran glycoside, which is a commonly used traditional Chinese medicine to treat patients with kidney and spleen-yang deficiency symptom. Psoralen has been reported to show estrogen-like activity, antioxidant activity, osteoblastic proliferation accelerating activity, antitumor effects and antibacterial activity. However, the antitumor mechanism of psoralen is not fully understood. This study aimed to investigate the therapeutic efficacy of psoralen in human hepatoma cell line SMMC7721 and the mechanism of antitumor effects.ResultsPsoralen inhibited proliferation of SMMC7721 in a dose- and time-dependent manner, and promoted apoptosis. Further, psoralen activated the ER stress signal pathway, including the expansion of endoplasmic reticulum, increasing the mRNA levels of GRP78, DDIT3, ATF4, XBP1, GADD34 and the protein levels of GDF15, GRP78, IRE1 alpha, XBP-1s in a time-dependent manner. Psoralen induces cell cycle arrest at G1 phase by enhancing CyclinD1 and reducing CyclinE1 expression. Moreover, TUDC couldn’t inhibit the psoralen-induced ER stress in SMMC7721 cells.ConclusionsPsoralen can inhibit the proliferation of SMMC7721 cells and induce ER stress response to induce cell apoptosis, suggesting that psoralen may represent a novel therapeutic option for the prevention and treatment hepatocellular carcinoma.

Bidirectional enantioselective synthesis of bis-benzofuran atropisomeric oligoarenes featuring two distal C-C stereogenic axes

We report the bidirectional enantioselective synthesis of bis-benzofuran atropisomeric oligoarenes featuring two distal C-C stereogenic axes obtained by a two-fold central-to-axial chirality conversion upon oxidative aromatization. The key enantioenriched centrally chiral bis-dihydrobenzofuran precursors were synthesized via a bidirectional diastereo- and enantio-selective organocatalyzed domino reaction between simple achiral and easily accessible dihydroxylated aromatics and chloronitroalkenes. Moreover, the stereodivergent nature of the methodology was established by synthesizing both diastereomers of a non-symmetrically functionalized bis-axially chiral oligoarene.
