In the present research, several novel and natural hydrophobic deep eutectic solvents (DESs) were prepared using methyltrioctylammonium chloride (MTOAC) as the hydrogen bond acceptor (HBA) and different types of straight chain alcs. as hydrogen bond donors (HBDs). One of the DESs composed of MTOAC and n-butanol was advantageously used to develop a vortex-assisted liquid phase microextraction (VALPME) method combined with high-performance liquid chromatog.-UV detection (HPLC-UV) for the determination of common acaricides in fruit juice samples. Several important parameters influencing extraction efficiency were investigated and optimized, including the type and volume of DES, sample solution pH, effect of salt addition and, extraction and vortex time. Under optimal exptl. conditions, the method showed good linearity with the correlation coefficients (R2) of 0.9986-0.9991 in the linear range of 2-300μg L-1, low limits of detection of 0.5-1μg L-1 and acceptable extraction recoveries in the range of 85-93%. The proposed method was successfully applied for the extraction and preconcentration of trace acaricides in real fruit juice samples, and the results demonstrated the potential of the synthesized DESs for the extraction and determination of contaminants in aqueous samples.

Abstract: Caenorhabditis elegans presents functioning, biol. relevant phenotypes and is frequently used as a bioindicator of toxicity. However, most C. elegans in vivo effect-assessment methods are laborious and time consuming. Therefore, we developed a novel method to measure the oxygen consumption rate of C. elegans as a sublethal endpoint of toxicity. This protocol was tested by exposing 50 larval stage one C. elegans individuals for 48 h (at 20°C) to different concentrations of two toxicants i.e. benzylcetyldimethylammonium chloride (BAC-C16) and cadmium (Cd). Following exposures, the oxygen consumption rate of the C. elegans individuals were measured using the high-throughput functionality of the Seahorse XF^e96 Extracellular Flux Analyzer. Dose-response curves for BAC-C16 (R² = 0.93; P = 0.001) and Cd (R² = 0.98; P = 0.001) were created. Furthermore, a strong, pos. correlation was evidenced between C. elegans oxygen consumption rate and a commonly used, ecol. relevant endpoint of toxicity (growth inhibition) for BAC-C16 (R² = 0.93; P = 0.0001) and Cd (R² = 0.91; P = 0.0001). The data presented in this study show that C. elegans oxygen consumption rate can be used as a promising functional measurement of toxicity.

Natalia Dias Soeiro. And the article was included in Molecules in 2018.SDS of cas: 95-88-5 The following contents are mentioned in the article:

Nowadays, quant. structure-activity relationship (QSAR) methods have been widely performed to predict the toxicity of compounds to organisms due to their simplicity, ease of implementation, and low hazards. In this study, to estimate the toxicities of substituted aromatic compounds to Tetrahymena pyriformis, the QSAR models were established by the multiple linear regression (MLR) and radial basis function neural network (RBFNN). Unlike other QSAR studies, according to the difference of functional groups (-NO₂, -X), the whole dataset was divided into three groups and further modeled sep. The statistical characteristics for the models are obtained as the following: MLR: n = 36, R² = 0.829, RMS (root mean square) = 0.192, RBFNN: n = 36, R² = 0.843, RMS = 0.167 for Group 1; MLR: n = 60, R² = 0.803, RMS = 0.222, RBFNN: n = 60, R² = 0.821, RMS = 0.193 for Group 2; MLR: n = 31 R² = 0.852, RMS = 0.192; RBFNN: n = 31, R² = 0.885, RMS = 0.163 for Group 3, resp. The results were within the acceptable range, and the models were found to be statistically robust with high external predictivity. Moreover, the models also gave some insight on those characteristics of the structures that most affect the toxicity.

And the article was included in Environmental Research in 2022.Name: Sodium tetrachloropalladate(II) The following contents are mentioned in the article:

Efficient reduction of chromate is highly desirable for its detoxification and remediation of the contaminated environment. This study described a fusion of the concepts of precious metal biorecovery and fabrication of Pd/Fe@biomass derived from simulated wastewater. The effectiveness of Pd/Fe@biomass during reduction process of Cr(VI) was evaluated by comparing with pure nZVI, E. faecalis and Pd@biomass. Results showed that Pd(II) could be recovered by E. faecalis with Fe(II) as the electron donor, and precipitation could yield nZVI anchored onto Pd-loaded E. faecalis. The nano particles (NPs) on Pd/Fe@biomass were well-dispersed, which provided 2.70 folds sp. surface area comparing with nZVI. Efficient Cr(VI) reduction could be achieved at a higher catalyst dosage, the most appropriated Pd/Fe molar ratio of 2% and a wide pH range. Typically, 0.5 mM Cr(VI) could be completely reduced in 5 min driven by Pd/Fe@biomass under the conditions of dosage of 1.0 g/L and pH 3. Moreover, the mechanisms of Cr(VI) reduction by Pd/Fe@biomass were proposed, which intimately related to nZVI electron donating capacities, Pd catalysis for hydrogenation and galvanic cell effects between Fe and Pd. Therefore, Pd/Fe@biomass could be an alternative for rapid and complete reduction of Cr(VI). This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Name: Sodium tetrachloropalladate(II)).

A series of novel benzo[c][1,2,5]oxadiazole derivatives were designed, synthesized, and biol. evaluated as inhibitors of PD-L1. Among them, compound I [R = H] exhibited 1.8 nM IC₅₀ value in a homogeneous time-resolved fluorescence (HTRF) assay, which was 20-fold more potent than the lead compound BMS-1016 (II). In the surface plasmon resonance (SPR) assay, compound I [R = H] bound to human PD-L1 (hPD-L1) with a K_D value of 3.34 nM, without showing any binding to hPD-1. In the cell-based coculture assay, compound I [R = H] blocked PD-1/PD-L1 interaction with an EC₅₀ value of 375 nM, while BMS-1016 had an EC₅₀ value of 2075 nM. Moreover, compound I [R = Et] , an ester prodrug of compound I [R = H], was orally bioavailable and displayed significant antitumor effects in tumor models of syngeneic and PD-L1 humanized mice. Mechanistically, compound I [R = Et] exhibited significant in vivo antitumor effects probably through promoting antitumor immunity. Together, this series of benzoxadiazole PD-L1 inhibitors holds promise for tumor immunotherapy.

Solvent impregnated resins (SIRs) were prepared by dry impregnation using styrene-divinylbenzene type macroreticular resin (HZ-818) as support and trioctylmethylammonium chloride as extractant. Adsorption and separation performance of In(III) and Fe(III) with SIRs was studied on HCl medium by static and dynamic adsorption method. The effect of HCl concentration on the adsorption of In(III) and Fe(III) was investigated by static adsorption method. The effect of feed flow rate, bed height, and metal ion concentration (In(III) and Fe(III)) was investigated by dynamic adsorption method. The optimized acidity for In(III) and Fe(III) adsorption with SIRs was 4 mol/L HCl in single-component and bi-component systems containing In(III) and Fe(III). The dynamic adsorption study revealed that when the concentration of HCl, feed flow rate, bed height, and metal ion concentration were 4 mol/L, 1.4 mL/min, 140 mm, and 90 mg/L at ambient temperature, the adsorption capacities of In(III) and Fe(III) in single-component system were 13.1 and 37.8 mg/g, resp., and the adsorption capacities of In(III) and Fe(III) in bi-component system were 1.3 and 35.8 mg/g, resp.

Removal of picloram herbicide from an aqueous environment using polymer inclusion membranes was written by Mwakalesi, Alinanuswe J.;Potter, Ian D.. And the article was included in Journal of Environmental Chemical Engineering in 2020.Product Details of 5137-55-3 The following contents are mentioned in the article:

The picloram (4-amino-3,5,6-trichloro-2-pyridinecarboxylic acid) herbicide is widely applied to control the growth of woody plants and it has been frequently detected in aqueous environments due to its poor adsorption by soils and high leaching potential. Consequently, the removal of picloram from contaminated environmental waters is of major concern due to its adverse impacts on aquatic organisms, soils and animals. The development of a method for the extraction and transport of picloram from aqueous solutions using a polymer inclusion membrane (PIM) composed of cellulose triacetate, trioctylmethylammonium chloride (Aliquat 336) and 2-nitrophenyl octyl ether (NPOE) is reported. The exptl. method was optimized for the PIM composition, and the type and concentration of stripping reagent. The optimized method demonstrated good performance indicators of flux and transport efficiency for picloram during non-competitive and competitive transport experiments The PIM was also successfully applied in a passive sampling device to recover picloram at the maximum permissable concentration of 500μg/L from a complex matrix of natural water. Findings from this study demonstrate that PIMs can serve as a potential alternative method for the removal and recovery of picloram and related herbicides from contaminated aqueous solutions This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Product Details of 5137-55-3).

Controlled Growth of Single-Crystal Pd Quantum Dots on 2D Carbon for Large Current Density Hydrogen Evolution was written by Zhang, Danyan;Zheng, Xuchen;Qi, Lu;Xue, Yurui;He, Feng;Li, Yuliang. And the article was included in Advanced Functional Materials in 2022.COA of Formula: Cl4Na2Pd The following contents are mentioned in the article:

The key issue for industrial large-scale hydrogen production by water electrolysis is developing environment-friendly electrocatalysts that can work well at large current densities and low overpotentials. Thanks to the superior advantages of 2D graphdiyne (GDY) on chem. structure and the alkyne bond strong reductivity, the highly selective, in situ growth of the single-crystal Pd (111) quantum dots is achieved. The metal dots distribute uniformly and densely on the GDY surface (GDY-Pd1) in a controllable way at low temperatures without adding addnl. reductive agents. Exptl. and theor. results show that the 2D GDY affords an ideal platform to construct highly selective and active electrocatalysts with accurate structures, defined valence states, facilitated charge transfer ability, and enhanced elec. conductivity for hydrogen evolution reaction. Remarkably, the electrocatalyst can reach 500 and 1000 mA cm^-2 at small overpotentials of only 201 and 261 mV, with high long-term stability, which are better than most of the reported ones. The results demonstrate that 2D DGY is an excellent support in the controllable synthesis of metal quantum dots with well-defined surface and structure and the potential to achieve large-scale preparation This study takes a critical step toward industrial hydrogen production This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6COA of Formula: Cl4Na2Pd).

Enhancement of adsorption efficiency of heavy metal Cu(II) and Zn(II) onto cationic surfactant modified bentonite was written by Tohdee, Kanogwan;Kaewsichan, Lupong;Asadullah. And the article was included in Journal of Environmental Chemical Engineering in 2018.Reference of 122-18-9 The following contents are mentioned in the article:

This study sought to enhance the metal adsorption capacity of bentonite by improving its surfaces. Surface modification by the cationic surfactant (Bencylhexadecyldimethyl ammonium chloride, BCDMACl) was successful in this respect, and was characterized by FTIR spectroscopy, XRF, BET, and swelling test. A major characteristic of BCDMACl is forming micelles that can intercalate into interlayers of clay and prevent swelling. The adsorption of Cu (II) and Zn (II) from aqueous solutions was studied in batch experiments, varying both contact time and concentrations of the metal ions. Retention of the metals in solution was detected by Atomic Absorption Spectroscopy (AAS). The adsorption data were fitted with Langmuir, Freundlich, and Dubinin-Radushkevich isotherm models, of which the Langmuir isotherm provided the best fit with exptl. data (R² range 0.962-0.993). The results also revealed that the modified bentonite had significantly improved adsorption capacities (q_max 50.76 and 35.21mg/g for Cu(II) and Zn(II), resp.); about 2.5 and 2.0 fold improvements over natural bentonite. The pseudo-second-order rate equation provided the best fit to observed adsorption kinetics. This study demonstrated the modified bentonite as an effective adsorbent for the removal of heavy metals from aqueous solutions This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Reference of 122-18-9).

In vitro screening for chemical inhibition of the iodide recycling enzyme, iodotyrosine deiodinase was written by Olker, Jennifer H.;Korte, Joseph J.;Denny, Jeffrey S.;Haselman, Jonathan T.;Hartig, Phillip C.;Cardon, Mary C.;Hornung, Michael W.;Degitz, Sigmund J.. And the article was included in Toxicology In Vitro in 2021.Application In Synthesis of N-Methyl-N,N-dioctyloctan-1-aminium chloride The following contents are mentioned in the article:

The iodide recycling enzyme, iodotyrosine deiodinase (IYD), is a largely unstudied mol. mechanism through which environmental chems. can potentially cause thyroid disruption. This highly conserved enzyme plays an essential role in maintaining adequate levels of free iodide for thyroid hormone synthesis. Thyroid disruption following in vivo IYD inhibition has been documented in mammalian and amphibian models; however, few chems. have been tested for IYD inhibition in either in vivo or in vitro assays. Presented here are the development and application of a screening assay to assess susceptibility of IYD to chem. inhibition. With recombinant human IYD enzyme, a 96-well plate in vitro assay was developed and then used to screen over 1800 unique substances from the U. S. EPA ToxCast screening library. Through a tiered screening approach, 194 IYD inhibitors were identified (inhibited IYD enzyme activity by 20% or greater at target concentration of 200μM). 154 chems. were further tested in concentration-response (0.032-200μM) to determine IC50 and rank-order potency. This work broadens the coverage of thyroid-relevant mol. targets for chem. screening, provides the largest set of chems. tested for IYD inhibition, and aids in prioritizing chems. for targeted in vivo testing to evaluate thyroid-related adverse outcomes. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Application In Synthesis of N-Methyl-N,N-dioctyloctan-1-aminium chloride).
