Evans, Nicola published the artcileIn vitro activity of a panel of per- and polyfluoroalkyl substances (PFAS), fatty acids, and pharmaceuticals in peroxisome proliferator-activated receptor (PPAR) alpha, PPAR gamma, and estrogen receptor assays, Recommanded Product: Ethyl 2-(4-chlorophenoxy)-2-methylpropanoate, the publication is Toxicology and Applied Pharmacology (2022), 116136, database is CAplus and MEDLINE.

Data demonstrate numerous per- and polyfluoroalkyl substances (PFAS) activate peroxisome proliferator-activated receptor alpha (PPARα), however, addnl. work is needed to characterize PFAS activity on PPAR gamma (PPARγ) and other nuclear receptors. We utilized in vitro assays with either human or rat PPARα or PPARγ ligand binding domains to evaluate 16 PFAS (HFPO-DA, HFPO-DA-AS, NBP2, PFMOAA, PFHxA, PFOA, PFNA, PFDA, PFOS, PFBS, PFHxS, PFOSA, EtPFOSA, and 4:2, 6:2 and 8:2 FTOH), 3 endogenous fatty acids (oleic, linoleic, and octanoic), and 3 pharmaceuticals (WY14643, clofibrate, and the metabolite clofibric acid). We also tested chems. for human estrogen receptor (hER) transcriptional activation. Nearly all compounds activated both PPARα and PPARγ in both human and rat ligand binding domain assays, except for the FTOH compounds and PFOSA. Receptor activation and relative potencies were evaluated based on effect concentration 20% (EC20), top percent of max fold induction (pmaxtop), and area under the curve (AUC). HFPO-DA and HFPO-DA-AS were the most potent (lowest EC20, highest pmaxtop and AUC) of all PFAS in rat and human PPARα assays, being slightly less potent than oleic and linoleic acid, while NBP2 was the most potent in rat and human PPARγ assays. Only PFHxS, 8:2 and 6:2 FTOH exhibited hER agonism >20% pmax. In vitro measures of human and rat PPARαand PPARγ activity did not correlate with oral doses or serum concentrations of PFAS that induced increases in male rat liver weight from the National Toxicol. Program 28-d toxicity studies. Data indicate that both PPARα and PPARγ activation may be mol. initiating events that contribute to the in vivo effects observed for many PFAS.

Brady, P. Rex published the artcileEvaluation of some reactive disperse dyes for sublimation transfer printing of wool, SDS of cas: 18791-02-1, the publication is Journal of the Society of Dyers and Colourists (1981), 97(4), 159-65, database is CAplus.

The transfer printing of wool by the sublimation method was examined using 12 azo and 2 anthraquinone low-mol.-weight dyes containing 6 different types of reactive groups. To achieve build-up of the dyes to heavy depths, the wool was pretreated with a polymer, e.g. Primal K3 (I) [37331-35-4], or a surfactant and steamed after dye transfer. Only the yellow dyes exhibited good fastness properties on pure wool. On wool-polyester blend fabrics that had been treated with I, fastness values were generally intermediate between those for pure polyester fabrics and I-treated wool.

Braguglia, C. M. published the artcileQuality assessment of digested sludges produced by advanced stabilization processes, Recommanded Product: N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Environmental Science and Pollution Research (2015), 22(10), 7216-7235, database is CAplus and MEDLINE.

The European Union (EU) Project Routes aimed to discover new routes in sludge stabilization treatments leading to high-quality digested sludge, suitable for land application. In order to investigate the impact of different enhanced sludge stabilization processes such as (a) thermophilic digestion integrated with thermal hydrolysis pretreatment (TT), (b) sonication before mesophilic/thermophilic digestion (UMT), and (c) sequential anaerobic/aerobic digestion (AA) on digested sludge quality, a broad class of conventional and emerging organic micropollutants as well as ecotoxicity was analyzed, extending the assessment beyond the parameters typically considered (i.e., stability index and heavy metals). The stability index was improved by adding aerobic posttreatment or by operating dual-stage process but not by pretreatment integration. Filterability was worsened by thermophilic digestion, either alone (TT) or coupled with mesophilic digestion (UMT). The concentrations of heavy metals, present in ranking order Zn > Cu > Pb > Cr ∼ Ni > Cd > Hg, were always below the current legal requirements for use on land and were not removed during the processes. Removals of conventional and emerging organic pollutants were greatly enhanced by performing double-stage digestion (UMT and AA treatment) compared to a single-stage process as TT; the same trend was found as regards toxicity reduction Overall, all the digested sludges exhibited toxicity to the soil bacterium Arthrobacter globiformis at concentrations about factor 100 higher than the usual application rate of sludge to soil in Europe. For earthworms, a safety margin of factor 30 was generally achieved for all the digested samples.

D’Onofrio, Jennifer published the artcileNovel cyclic phosphate-linked oligosaccharides (CyPLOSs) covalently immobilized on solid supports for potential cation scavenging, SDS of cas: 33697-81-3, the publication is European Journal of Organic Chemistry (2007), 3849-3858, database is CAplus.

For potential cation scavenging both from water and from organic solvents, a synthetic procedure for functionalization of a Tentagel solid support with novel cyclic phosphate-linked oligosaccharide (CyPLOS) analogs I (R = TBDMS, H) is described. To establish the feasibility of the synthetic strategy, the cyclic dimer was the model compound selected to be incorporated onto the solid support. This functionalization was achieved through a stepwise solid-phase synthesis of the linear dimer, obtained by standard phosphoramidite protocols, followed by a synthesis of the cyclic mol. on the resin. The key intermediate was a suitably derivatized sugar phosphoramidite building block II, with the secondary hydroxy functions masked as TBDMS ethers. This proved to be an orthogonal protection with respect to the DMT ether, fully compatible with the phosphoramidite and the phosphotriester chem. used for the oligomerization and the cyclization process onto the solid support, resp. Conditions for the total unmasking of the hydroxy groups of the cyclic dimer, not affecting the integrity of the cyclic structure nor its linkage with the solid matrix, have been optimized. Gel-phase ³¹P NMR spectroscopy has been used extensively here to monitor the efficiency of the reactions carried out on the solid support.

A series of new benzothiazole derivatives containing dimethylpyrazole I [R = H, n-pentyl, benzyl, etc.] were synthesized and evaluated for their anticonvulsant activity, neurotoxicity and cytotoxicity by using the maximal electroshock (MES), rotarod neurotoxicity (TOX) and MTT colorimetric assay. Among the compounds studied, four compounds I [R = Bu, n-pentyl, 2-fluorobenzyl, 2,6-dichlorobenzyl] showed better anticonvulsant than the others at 300 mg/kg and they also showed anticonvulsant activity at the dose of 100 mg/kg. All the synthetic compounds I showed lower neurotoxicity and little cytotoxicity, so that the compounds, which with better activities, also had higher protective index. In particular, the compound I [R = 2-fluorobenzyl] showed better activity with an ED₅₀ value of 160.4 mg/kg and higher protective index (PI) values of 2.74 in the MES test than the standard drugs sodium valproate, which used as pos. controls in this study. After that the compound I [R = 2-fluorobenzyl] demonstrated antagonistic activity against seizures induced by pentylenetetrazol, which proved compound I [R = 2-fluorobenzyl] may be exert activity through effecting GABAergic neurotransmission.

Xiao, Chunsheng published the artcileSide chain impacts on pH- and thermo-responsiveness of tertiary amine functionalized polypeptides, SDS of cas: 4584-49-0, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (2014), 52(5), 671-679, database is CAplus.

The systemic investigation of the structural impacts of side chains on the pH- and thermo-responsiveness of tertiary amine functionalized poly(L-glutamate)s (TA-PGs) was carried out. The TA-PGs polymers were effectively synthesized by Cu(I)-catalyzed azide-alkyne cycloaddition click reaction of azido tertiary amines with poly(γ-propargyl-L-glutamate) (PPLG). Turbimetric measurements were performed to characterize the pH- and temperature-induced phase transition of TA-PGs in aqueous solution, which suggested a structural dependence of the properties on the N-substituted groups and the “linkers” between 1,2,3-triazole ring and the tertiary amine groups in the side chains. In detail, the pH responsive properties of TA-PGs were basically determined by the hydrophobicity of the N-substituted groups in the side chains and the pH transition point (pH_t) decreased as the increasing hydrophobicity of the N-substituted groups, while the temperature-responsiveness of TA-PGs were affected by either the N-substituted groups or the “linkers.” TA-PGs with a moderate N-substituted amine group (e.g., DEA, PR, and PD) or a branched “linker” (e.g., iso-propylene and 2-methylpropylene group) were more likely to express the LCST-type phase transition tuned by pH variation. These structure-property relationships revealed in this study would help to develop the applications of TA-PGs in smart drug delivery systems. © 2013 Wiley Periodicals, Inc. J. Polym.

Selective oxidation of organic substrates by environment-friendly oxidizing agents is an important ingredient of the sustainable chem. industry. Here we report a comprehensive study in the field of metal peoroxocomplex catalysis for the selective liquid phase oxidation of various organic substrates. A number of well-defined bi-functional tungsten complex catalysts with tetra nuclear structure {PO4[WO(O₂)₂]₄}^3- in combination with a phase-transfer agents were synthesized. The structural properties were thoroughly studied using of IR, Raman and EXAFS spectroscopy. By combining different spectroscopy techniques were able to elucidate the effect of quaternary ammonium cations on the structural properties of the resulting peroxo complexes. The catalytic properties of these well-defined material were then evaluated in bi-phasic selective oxidation of cyclooctene, Me oleate and N-phosphonomethyliminodiacetic acid with hydrogen peroxide under mild conditions. For every substrate we were able to achieve high conversion at the selectivity towards a target product close to 100%.
