Removal of pollutants and reduction of bio-toxicity in a full scale chemical coagulation and reverse osmosis leachate treatment system

Removals of pollutants and toxic organic compounds and reduction in bio-toxicity of leachate along an operating full-scale leachate treatment system utilizing chemical coagulation, sand filtration, microfiltration (MF) and reverse osmosis (RO) membrane were evaluated. High pollutant removals were achieved mainly by coagulation and sand filtration. Major toxic organic pollutants, i.e. DEHP, DBP and bisphenol A were removed by 100%, 99.6% and 98.0%. Acute toxicity test using water flea, Nile Tilapia and common carp and genotoxicity (Comet assay) were conducted to determine toxicity reduction in leachate along the treatment. Ammonia was found to be the main acute toxic compounds in leachate as determined by LC50 but the effect of organic substances was also observed. DNA damage in fish exposed to diluted raw leachate (10% of LC50) was found to be 8.9-24.3% and it was subsequently decreased along the treatment. Correlation between pollutants and its bio-toxicity was established using multivariable analyses.

Design, synthesis, and antifungal activity of inhibitors of brassilexin detoxification in the plant pathogenic fungus Leptosphaeria maculans

Potential inhibitors of Leptosphaeria maculans mediated detoxification of the phytoalexin brassilexin were designed and synthesized based on the planar heteroaromatic structure of isothiazolo[5,4-b]indole. Screening of these compounds for inhibition of brassilexin detoxification in cultures of L. maculans indicated that 4-(2-chlorophenyl)isothiazole had the largest effect on the rate of brassilexin detoxification. However, the most antifungal compound among the potential inhibitors, isothiazolo[5,4-b]quinoline, did not appear to affect the metabolism of brassilexin noticeably, suggesting that growth inhibition is not sufficient to slow down the rate of brassilexin detoxification. Furthermore, it was determined that 4-arylisothiazoles as well as isothiazolo[5,4-b]thianaphthene displayed antifungal activity against L. maculans.

Metabolism and disposition of ataluren after oral administration to mice, rats, dogs, and humans

Ataluren is a unique small molecule developed for the treatment of diseases caused by nonsense mutations, which result in premature termination of ribosomal translation and lack of full-length protein production. This study investigated the in vivo metabolism and disposition of ataluren in mice, rats, dogs, and humans. After single oral administration of [14C]ataluren, the overall recovery of radioactivity was ?93.7%, with approximately 39%, 17%-21%, 12%, and 55% in the urine and 54%, 70%-72%, 80%, and 47% in the feces from intact mice, rats, dogs, and humans, respectively. In bile duct-cannulated (BDC) rats, approximately 10%, 7%, and 82% of the dose was recovered in the urine, feces, and bile, respectively, suggesting that biliary secretion was a major route for the elimination of ataluren in the rats. Ataluren was extensively metabolized after oral administration, and the metabolic profiles of ataluren were quantitatively similar across all species. Unchanged ataluren was the dominant radioactive component in plasma. Ataluren acyl glucuronide was the most prominent metabolite in plasma of all species and the dominant metabolite in BDC rat bile and human urine, whereas the oxadiazole cleavage products were the major or prominent metabolites in the feces of all species. Overall, the results indicate that phase I metabolism is negligible and that the pathway largely involves glucuronidation. No other circulatory conjugation metabolite was detected across investigated species. SIGNIFICANCE STATEMENT Ataluren is a novel carboxylic acid-containing small molecule drug for treating nonsense mutation Duchenne muscular dystrophy. In vivo metabolism and disposition after a single dose of the drug were investigated in mice, rats, dogs, and humans. Phase I metabolism of ataluren was negligible, and the pathway largely involves glucuronidation. No other circulatory conjugation metabolite was detected across investigated species.

Volatile composition and sensory and quality attributes of quince (Cydonia oblonga Mill.) fruits as affected by water stress

No information exists on the effect of water deficit on quince (Cydonia oblonga Mill.) fruit quality characteristics. In this paper, the effect of withholding irrigation water in the middle of the rapid fruit growth period on yield, main fruit physicochemical characteristics, sensory profile, and volatile composition of quince (cv. BA-29) was studied. The linear fruit growth phase was seen to be a critical phenological period for the marketable yield of quince because water deficit decreased the fruit weight, size, and moisture content. Also, this period was clearly critical for the fruit’s chemical characteristics. Water deficit induced important changes in an important number of the identified volatile compounds, characterized by decreases on pear, pineapple and apple sensory descriptors and increases on the green-herbaceous sensory descriptors. Moreover, total soluble solids increased and the total polyphenols content and antioxidant activity decreased as a result of water deficit effect, even though the still high levels of total polyphenols, regardless of the fruit water status, suggested that quinces can be used as an important source of natural antioxidants. The fruit sensory analysis indicated that the peel colour intensity of fruits from the water deficit treatment increased and fruit flesh texture improved. Indeed, the main handicaps for its consumption as fresh fruit (corkiness and fibreness) severely decreased and crunchiness increased.

Replacement of oxygen by sulfur in small organic molecules. 3. Theoretical studies on the tautomeric equilibria of the 2OH and 4OH-substituted oxazole and thiazole and the 3OH and 4OH-Substituted isoxazole and isothiazole in the isolated state and in solution

This follow-up paper completes the author?s investigations to explore the in-solution structural preferences and relative free energies of all OH-substituted oxazole, thiazole, isoxazole, and isothiazole systems. The polarizable continuum dielectric solvent method calculations in the integral-equation formalism (IEF-PCM) were performed at the DFT/B97D/aug-cc-pv(q+(d))z level for the stable neutral tautomers with geometries optimized in dichloromethane and aqueous solution. With the exception of the predictions for the predominant tautomers of the 3OH isoxazole and isothiazole, the results of the IEF-PCM calculations for identifying the most stable tautomer of the given species in the two selected solvents agreed with those from experimental investigations. The calculations predict that the hydroxy proton, with the exception for the 4OH isoxazole and 4OH isothiazole, moves preferentially to the ring nitrogen or to a ring carbon atom in parallel with the development of a C=O group. The remaining, low-fraction OH tautomers will not be observable in the equilibrium compositions. Relative solvation free energies obtained by the free energy perturbation method implemented in Monte Carlo simulations are in moderate accord with the IEF-PCM results, but consideration of the DeltaGsolv/MC values in calculating DeltaGstot maintains the tautomeric preferences. It was revealed from the Monte Carlo solution structure analyses that the S atom is not a hydrogen-bond acceptor in any OH-substituted thiazole or isothiazole, and the OH-substituted isoxazole and oxazole ring oxygens may act as a weak hydrogen-bond acceptor at most. The molecules form 1.0?3.4 solute?water hydrogen bonds in generally unexplored numbers at some specific solute sites. Nonetheless, hydrogen-bond formation is favorable with the NH, C=O and OH groups.

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.Synthetic Route of 288-16-4, you can also check out more blogs about288-16-4
