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.

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.

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.

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.

Zhang, Huaisheng published the artcileDiscovery of a quinoline-based phenyl sulfone derivative as an antitrypanosomal agent, Application of 3-Chloro-4-hydroxyphenylacetic acid, the publication is Bioorganic & Medicinal Chemistry Letters (2018), 28(9), 1647-1651, database is CAplus and MEDLINE.

A series of natural products-based Ph sulfone derivative and their property-based analogs were investigated as potential growth inhibitors of Trypanosoma brucei. Trypanosoma brucei is a kinetoplastid protozoan parasite that causes trypanosomiasis. In this work, the authors found that nopol- and quinoline-based Ph sulfone derivative were the most active and selective for T. brucei, and they were not reactive towards the active thiol of T. brucei’s cysteine protease rhodesain. A thiol reactive variant of the quinoline-based Ph sulfone was subsequently investigated and found to be a moderate inhibitor of rhodesain. The quinoline-based compound that is not reactive towards rhodesain can serve a template for phenotypic-based lead discovery while its thiol-active congener can serve as template for structure-based investigation of new antitrypanosomal agents.

A newly developed robust catalyst [Ir(COD)(Phen)Cl] (A) was used for the C-H borylation of three dozen aromatics and heteroaromatics with excellent yield and selectivity. Activation of the catalyst was identified using catalytic amounts of H₂O, alcs., etc., when B₂pin₂ was used in noncoordinating solvents, while for THF catalytic use of HBpin was required. The results were on par with the in situ based expensive system [Ir(OMe)(COD)]₂/dtbbpy or Me₄Phen.

Maximo, Patricia published the artcilePhotomodulation of ultrastable host-guest complexes in water and their application in light-controlled steroid release, Synthetic Route of 219537-97-0, the publication is Organic Chemistry Frontiers (2022), 9(16), 4238-4249, database is CAplus.

The cucurbit[8]uril (CB8) synthetic receptor was shown to form high-affinity host-guest complexes with dicationic dithienylethene (DTE) photoswitches I [R = H, Me; R¹ = 1-iodo-1-methyl-2-pyridyl, 1-iodo-1-methyl-3-pyridyl, 1-iodo-1-methyl-4-pyridyl] in water. ITC experiments combined with computational studies suggest that the formation of the inclusion complexes was mainly driven by a combination of hydrophobic effects, ion-dipole, hydrogen- and chalcogen-bonding interactions. The binding affinities were observed to be much higher for the DTE closed isomers, reaching values in the picomolar range (up to 10¹¹ M^-1) while the open isomers display up to 10 000-fold lower affinities, setting ideal conditions for the development of robust photoswitchable host-guest complexes. The light-responsive affinity of these photoswitches toward CB8 was explored to control the encapsulation and release of nanomolar affinity steroids via competitive guest replacement.
