Quantification, distribution, and effects of di (2-ethylhexyl) phthalate contamination: Risk analysis and mitigation strategies in urban environment

Phthalate acid ester, di (2-ethylhexyl) phthalate (DEHP) is ubiquitously detected contaminant of emerging concerns (CECs) in all the environmental samples. The present study attempted to understand the fate and transport of DEHP in urban areas by evaluating the quantities, distribution, risk, and effects in the Mysuru city, India. The study is anticipated to serve as a vital document for local and national regulators to frame a robust DEHP management plan and mitigate the risks associated. Liquid-liquid microextraction followed by gas chromatographic analysis was adopted to determine the concentrations of DEHP. The risk quotient method was adopted to assess potential risk, and a conceptual planning model framework was designed to mitigate the DEHP contamination. The municipal wastewater contained 115 +/- 9.2 mu g/L, whereas treated municipal wastewater showed 95 +/- 7.6 mu g/L DEHP that was attributed to the inefficiency of the treatment plant. Further, sediments in surface water, as well as groundwater samples of the study area, showed 8 +/- 0.64 to 12 +/- 0.96 mu g/L and 32 +/- 2.56 to 40 +/- 3.2 mu g/kg of DEHP, respectively. The risk quotient of 19.17 for samples in around treatment indicated highest risk, whereas groundwater samples had a risk quotient of 1-2 indicating relative risk to aquatic organisms. In addition, the study highlighted the source, possible entry pathways, and management strategies including treatment aspects to draw an understanding of the distribution and potential ecological imbalances with contamination of DEHP in the urban sector. Practitioner points Understand the fate and transportation of DEHP in urban wastewater. Primary investigation and assessment to possible health and environmental risks of DEHP contamination in urban wastewater. Revealed the associated health risks and proposed possible management strategies.

Iodine-mediated formal [3+2] annulation for synthesis of furocoumarin from oxime esters

A novel synthesis of furocoumarins was developed by a reaction between oxime esters and 4-hydroxycoumarins. The reaction was proposed to undergo radical mechanism mediated by iodine, a cheap and common laboratory reagent. Mechanistic studies showed the key for the successful transformation was the presence of alpha-iodoimine intermediate which facilitated the ring-closing step. The developed conditions produced good functional group tolerance with a wide range of high-profile furocoumarin product. The potential for this strategy to be applied in other syntheses of heterocyclic compounds is highly achievable.

Evaluating Classical Force Fields against Experimental Cross-Solvation Free Energies

Experimental solvation free energies are nowadays commonly included as target properties in the validation and sometimes even in the calibration of condensed-phase force fields. However, this is often done in a nonsystematic fashion, by considering available solvation free energies involving an arbitrary collection of solutes in a limited set of solvents (e.g., water, octanol, chloroform, cyclohexane, or hexane). Here, this approach is made more systematic by introducing the concept of cross-solvation free energies Delta(s)G(A:B)(circle minus) for a set of N molecules that are all in the liquid state under ambient conditions, namely the matrix of N-2 entries for Delta(s)G(A:B)(circle minus) considering each of the N molecules either as a solute (A) or as a solvent (B). Relying on available experimental literature followed by careful data curation, a complete Delta(s)G(A:B)(circle minus) matrix of 625 entries is constructed for 25 molecules with one to seven carbon atoms representative for alkanes, chloroalkanes, ethers, ketones, esters, alcohols, amines, and amides. This matrix is then used to compare the relative accuracies of four popular condensed-phase force fields: GROMOS-2016H66, OPLS-AA, AMBER-GAFF, and CHARMM-CGenFF. In broad terms, and in spite of very different force-field functional-form choices and parametrization strategies, the four force fields are found to perform similarly well. Relative to the experimental values, the root-mean-square errors range between 2.9 and 4.0 kJ.mol(-1) (lowest value of 2.9 for GROMOS and OPLS), and the average errors range between -0.8 and +1.0 kJ.mol(-1) (lowest magnitude of 0.2 for AMBER and CHARMM). These differences are statistically significant but not very pronounced, especially considering the influence of outliers, some of which possibly caused by inaccurate experimental data.

DHA 12-LOX-derived oxylipins regulate platelet activation and thrombus formation through a PKA-dependent signaling pathway

Background The effects of docosahexaenoic acid (DHA) on cardiovascular disease are controversial and a mechanistic understanding of how this omega-3 polyunsaturated fatty acid (omega-3 PUFA) regulates platelet reactivity and the subsequent risk of a thrombotic event is warranted. In platelets, DHA is oxidized by 12-lipoxygenase (12-LOX) producing the oxidized lipids (oxylipins) 11-HDHA and 14-HDHA. We hypothesized that 12-LOX DHA-oxylipins may be involved in the beneficial effects observed in dietary supplemental treatment with omega-3 PUFAs or DHA itself. Objectives To determine the effects of DHA, 11-HDHA, and 14-HDHA on platelet function and thrombus formation, and to elucidate the mechanism by which these omega-3 PUFAs regulate platelet activation. Methods and results DHA, 11-HDHA, and 14-HDHA attenuated collagen-induced human platelet aggregation, but only the oxylipins inhibited IIb beta 3 activation and decreased -granule secretion. Furthermore, treatment of whole blood with DHA and its oxylipins impaired platelet adhesion and accumulation to a collagen-coated surface. Interestingly, thrombus formation was only diminished in mice treated with 11-HDHA or 14-HDHA, and mouse platelet activation was inhibited following acute treatment with these oxylipins or chronic treatment with DHA, suggesting that under physiologic conditions, the effects of DHA are mediated through its oxylipins. Finally, the protective mechanism of DHA oxylipins was shown to be mediated via activation of protein kinase A. Conclusions This study provides the first mechanistic evidence of how DHA and its 12-LOX oxylipins inhibit platelet activity and thrombus formation. These findings support the beneficial effects of DHA as therapeutic intervention in atherothrombotic diseases.

Stability of 3-deoxyanthocyanin pigment structure relative to anthocyanins from grains under microwave assisted extraction

Sorghum derived 3-deoxyanthocyanin (DXA) pigments are stable relative to their anthocyanin analogs, and are of growing interest in food applications. However, the 3DXA are poorly extractable from grain tissue. This work aimed to determine the relative stability and extractability of sorghum 3-DXA vs anthocyanins from maize and cowpea under microwave-assisted extraction (MAE). UV-Vis and UPLC-MS/MS spectrometry were used to characterize the properties. The 3-DXA remained structurally stable to MAE conditions up to 1200 W/100 degrees C/30 min. MAE increased sorghum 3-DXA yield 100% versus control (3100 vs 1520 mg/g). On the other hand, both maize and cowpea anthocyanins were unstable and rapidly degraded under MAE. Cell wall-derived ferulate esters were detected in sorghum and maize MAE extracts, indicating cell wall degradation occurred during MAE. Thus the enhanced extraction of 3-DXA under MAE was due to their structural stability, along with improved diffusion from cell matrix due to microwave-induced sorghum cell wall disruption.

Degradable and curable poly(conjugated ester)s prepared by acryl- and conjugate-substitutions of the ‘smallest’ monomer

alpha-(Chloromethyl)acryloyl chloride was polymerized with various bisphenols and diamines to yield poly(conjugated ester)s. The polymer prepared from bisphenol Z underwent curing by heating at 170 degrees C, while copolymerization with methyl methacrylate afforded a crosslinked polymer. The poly(conjugated ester)s were chemically decomposed via main-chain scission by the conjugate substitution with benzyl mercaptan. Moreover, the treatment with 5 wt% aqueous ammonia resulted in complete main-chain scission to the monomeric units by conjugate substitution and acyl substitution reaction, recovering bisphenol Z. Although curing and main-chain scission resulted in contractive changes on polymer properties, both reactions were achieved by a same skeleton, alpha-(aryloxymethyl)acrylate. Thus, alpha-(chloromethyl)acryloyl chloride is the smallest monomer to incorporate such a curable and degradable skeleton.

SiO2 supported Ni-In intermetallic compounds: Efficient for selective hydrogenation of fatty acid methyl esters to fatty alcohols

Ni/SiO2 and SiO2 supported Ni2In, NiIn and Ni2In3 intermetallic compounds (IMCs) were prepared by the sol-gel method and tested for the selective hydrogenation of methyl esters to fatty alcohols. It was found that the Ni phyllosilicate formed during the sol-gel process leads to high Ni dispersion. In IMCs, the Ni atoms are homogeneously isolated by the In ones and the charge is transferred from In to Ni. In the selective hydrogenation, decarbonylation/decarboxylation dominatingly occur on Ni/SiO2, while SiO2 supported IMCs mainly give fatty alcohols, and the yield of fatty alcohol can reach above 94 %. We suggest that it is the synergetic effect between Ni and In that facilitates the selective hydrogenation to yield fatty alcohols. The catalyst stability was also investigated, and the catalyst deactivation is mainly ascribed to the carbonaceous deposit.

General procedure: All microwave reactions were carried out in a capped (10 mL) microwave-vessel (Borosilicate glass vial sealed) that was placed in a microwave cavity. The pressure was set at 17 bar (average of an effective pressure = 4 bar) with power 75 W. DIEA (3.4 g, 3.4 mmol) was added to a solution of either 2,5-difluoro-4-(pyrrolidin-1-yl) benzoylchloride 12 (0.83 g, 3.4 mmol) or 2,5-difluoro-4-(pyrrolidin-1-yl)benzothioyl chloride 13 (0.88 g, 3.4 mmol) and ethyl-3-(diethylamino)acrylate 14 (0.45 g, 3.1 mmol) in acetonitrile (5 mL). The mixture reaction was held at 100 C for 20 min. After the reaction vessel was cooled to room temperature, the crude product was diluted with water (10 mL) and extracted with ethyl acetate(3 ¡Á 10 mL).
