SDS is widely used in sample preparation for proteomic research. However, SDS is incompatible with LC and electrospray ionization. SDS depletion is therefore required ahead of LC-MS anal. Most of current SDS removal strategies are time consuming, laborious, and have low reproducibility. Here, we describe a method, SDS-cyclodextrin (CD)-assisted sample preparation, by which CD can bind to SDS and form CD-SDS complexes in solutions, allowing for direct tryptic digestion. We demonstrate that SDS-CD-assisted sample preparation is a simple, fast, and robust SDS-based sample preparation method for proteomics application.

Li, Yongwang published the artcileA study on the rules of ligands in highly efficient Ru-amide/AC catalysts for acetylene hydrochlorination, Recommanded Product: 2-Chloroacetamide, the publication is Catalysis Science & Technology (2021), 11(22), 7347-7358, database is CAplus.

To explore the role of substituents on ligands in the modification of metal catalysts, a series of Ru-amide/AC catalysts are synthesized with various amide ligands derived from formamide and assessed for acetylene hydrochlorination. Activity evaluation reveals a rule that replacing a hydrogen on formamide with an electron donor substituent can enhance the catalytic performance, while electron withdrawing substituents have the opposite effect. However, formanilide, which violates this law, shows the best modification effect, which is proved to be the effect of steric hindrance by characterization and DFT calculation Therefore, another rule is concluded that the electron donor ability and steric hindrance of substituents on amide ligands jointly affect the modification effect. Finally, benzanilide, with a superior modification effect, which searched based on the above results, gives strong evidence for the correction of these rules. This work provides a theor. basis for the search for efficient ligands for acetylene hydrochlorination.

Abstract: In order to find efficient new antitumor drugs, a series of novel pyrimidine derivatives containing urea moiety were designed and synthesized, and the antitumor activity of four human tumor cells was evaluated by MTT anal. The results showed that most of the target compounds exhibited moderate antitumor activity. In particular, the IC₅₀ (concentration required to achieve 50% inhibition of the tumor cell proliferation) value of compound 2-((4-(4-ethylphenoxy)-6-(trifluoromethyl)pyrimidin-2-yl)thio)-N-((4-ethylphenyl)carbamoyl)acetamide for MGC-803 (human gastric carcinoma cell line) was 2.51 ± 0.17μmol L^-1, the anti-proliferative activity was significantly better than the pos. control drug 5-fluorouracil. Mol. docking revealed that this compound can bind well to the active site of epidermal growth factor receptor (EGFR), and it may become a potential antitumor drug.

Ratanaphain, Chatkrita published the artcileReactivity characterization of SiO₂-coated nano zero-valent iron for iodoacetamide degradation: The effects of SiO₂ thickness, and the roles of dehalogenation, hydrolysis and adsorption, COA of Formula: C2H4ClNO, the publication is Chemosphere (2022), 286(Part_3), 131816, database is CAplus and MEDLINE.

The effect of SiO₂-layer thickness in SiO₂-coated nano zero-valent iron (nZVI) particles on the reactivity characteristics of iodoacetamide (IAcAm) degradation was evaluated. SiO₂-layer thicknesses ranging from 3.6 to 27.3 nm were obtained through varying tetra-Et orthosilicate dosages of 0.001^-1 M. The crystallinity, surface chem. composition, and physicochem. properties were evaluated for their effects on synergetic degradation mechanisms, dehalogenation, hydrolysis, and adsorption. At a thickness of 3.6 nm, the SiO₂ layer offered the highest observed pseudo-first-order rate (kobs) and higher rates of IAcAm degradation were maintained under pH fluctuations (pH 5-7) and aerobic conditions compared to pristine nZVI. At this SiO₂-layer thickness (3.6 nm), the rate of iron oxide-layer formation was reduced and the migration of reactive iron species (Fe⁰ and Fe²⁺) for the dehalogenation and hydrolysis reactions was enabled. In a single-solute solution, IAcAm elimination was greater than bromoacetamide and chloroacetamide elimination due to the weak ionic I-C bond. In mixed solute conditions, the hydrophobicity of chloroacetamide played a more significant role in competitive degradation through greater adsorption. The proportion of dehalogenation relative to hydrolysis during IAcAm degradation by pristine nZVI and SiO₂-coated nZVI was approx. 0.6:0.4. Iodoacetic acid and acetic acid were detected as intermediates in the degradation pathway of IAcAm by pristine nZVI. In contrast, the SiO₂ layer on nZVI can accelerate the transformation of IAcAm to acetamide and iodoacetic acid. The electrolyte background of tap water exhibited a slight inhibitory effect on the degradation of IAcAm for both nZVI and SiO₂-coated nZVI.

Belarbi, Saida published the artcileComparison of Different d-SPE Sorbent Performances Based on Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) Methodology for Multiresidue Pesticide Analyses in Rapeseeds, Application of 2-Chloroacetamide, the publication is Molecules (2021), 26(21), 6727, database is CAplus and MEDLINE.

Pesticide extraction in rapeseed samples remains a great anal. challenge due to the complexity of the matrix, which contains proteins, fatty acids, high amounts of triglycerides and cellulosic fibers. An HPLC-MS/MS method was developed for the quantification of 179 pesticides in rapeseeds. The performances of the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method were evaluated using different dispersive solid-phase extraction (d-SPE) sorbents containing common octadecylsilane silica/primary-secondary amine adsorbent (PSA/C18) and new commercialized d-SPE materials dedicated to fatty matrixes (Z-Sep, Z-Sep+, and EMR-Lipid). The anal. performances of these different sorbents were compared according to the SANTE/12682/2019 document. The best results were obtained using EMR-Lipid in terms of pesticide average recoveries (103 and 70 of the 179 targeted pesticides exhibited recoveries within 70-120% and 30-70%, resp., with low RSD values). Moreover, the limits of quantification (LOQ) range from 1.72 μg/kg to 6.39 μg/kg for 173 of the pesticides. Only the recovery for tralkoxydim at 10 μg/kg level was not satisfactory (29%). The matrix effect was evaluated and proved to be limited between -50% and 50% for 169 pesticides with this EMR-Lipid and freezing. GC-Orbitrap analyses confirmed the best efficiency of the EMR-Lipid sorbent for the purification of rapeseeds.

Uzal-Varela, Rocio published the artcileUnderstanding the Effect of the Electron Spin Relaxation on the Relaxivities of Mn(II) Complexes with Triazacyclononane Derivatives, Application of 2-Chloroacetamide, the publication is Inorganic Chemistry (2021), 60(20), 15055-15068, database is CAplus and MEDLINE.

Investigating the relaxation of water ¹H nuclei induced by paramagnetic Mn(II) complexes is important to understand the mechanisms that control the efficiency of contrast agents used in diagnostic magnetic resonance imaging (MRI). Herein, a series of potentially hexadentate triazacyclononane (TACN) derivatives containing different pendant arms were designed to explore the relaxation of the electron spin in the corresponding Mn(II) complexes using a combination of ¹H NMR relaxometry and theor. calculations These ligands include 1,4,7-triazacyclononane-1,4,7-triacetic acid (H₃NOTA) and three derivatives in which an acetate group is replaced by sulfonamide (H₃NO2ASAm), amide (H₂NO2AM) or pyridyl (H₂NO2APy) pendants, resp. The analog of H₃NOTA containing three propionate pendant arms (H₃NOTPrA) was also investigated. The x-ray structure of the derivative containing two acetate groups and a sulfonamide pendant arm [Mn(NO2ASAm)]^– evidenced six-coordination of the ligand to the metal ion, with the coordination polyhedron being close to a trigonal prism. The relaxivities of all complexes at 20 MHz and 25° (1.1-1.3 mM^-1 s^-1) are typical of systems that lack water mols. coordinated to the metal ion. The nuclear magnetic relaxation profiles evidence significant differences in the relaxivities of the complexes at low fields (<1 MHz), which are associated with different spin relaxation rates. The zero field splitting (ZFS) parameters calculated using DFT and CASSCF methods show that electronic relaxation is relatively insensitive to the nature of the donor atoms. However, the twist angle of the two tripodal faces that delineate the coordination polyhedron, defined by the N atoms of the TACN unit (lower face) and the donor atoms of the pendant arms (upper face), has an important effect in the ZFS parameters. A twist angle close to the ideal value for an octahedral coordination (60°), such as that in [Mn(NOTPrA)]^–, leads to a small ZFS energy, whereas this value increases as the coordination polyhedron approaches to a trigonal prism.

Baran, Nicole published the artcilePesticides in groundwater at a national scale (France): Impact of regulations, molecular properties, uses, hydrogeology and climatic conditions, Computed Properties of 79-07-2, the publication is Science of the Total Environment (2021), 148137, database is CAplus and MEDLINE.

Contaminants in groundwater are a major issue worldwide. Temporal trends of such occurrences in French groundwaters were evaluated for several active substances of pesticides belonging to different chem. classes, to identify key factors explaining groundwater contamination. Our study relied on exploitation of a French national database (ADES, created in the mid-1990s and remarkable for the available data, including over 88 million analyses). Temporal changes in the frequency of exceeding a reference value of 0.1μg/L for several substances were determined at yearly and monthly scales. Such trends were examined by distinguishing different periods according to changes in regulations (new approval, withdrawal, or dose reduction), and were combined with data on effective rainfall as a proxy for groundwater recharge, on aquifer lithol., and on sales of active substances as a proxy for actual applications. A review of monthly data shows that a rapid transfer of pesticides with contrasting physico-chem. properties can occur after application in many aquifers, regardless of their lithol. For substances such as metolachlor, showing a sharp increase in sales, a clear relationship exists between quantities sold and frequency of exceeding the reference value. For other active substances, such as isoproturon or chlortoluron, frequencies of exceedance are governed by both sales and effective rainfall. Finally, the occurrence of active substances in groundwater several years after their withdrawal from the market is explained by at least three major mechanisms: the transfer time from soil into groundwater, processes of remobilization from soil and/or unsaturated zone, and no or low degradation in the saturated zone. While these processes are well documented for atrazine and different types of aquifers, they can be virtually unknown for other active substances.

Two value added C-C cross coupling reactions; Sonogashira and Stille couplings were achieved at milder conditions in the catalytic presence of a magnetically recoverable heterogeneous catalyst Fe₃O₄@SiO₂ immobilized Pd(II)-thioether containing NHC. The catalyst was earlier reported for Suzuki-Miyaura reaction and as an extension of its catalytic efficiency, the Stille and Sonogashira cross coupling reactions under aerobic condition had been explored in present report. The Sonogashira coupling of aryl bromides and terminal alkynes produced an excellent yield (∼96% at 0.25 mol% Pd) of the desired coupling product under copper and amines free conditions. Moreover, an excellent Stille coupling of readily available and more latent aryl chlorides and trialkylstannane was obtained (yields up to 95% at 0.25 mol% Pd) in absence of toxic fluorides additives. The broad substrate scope of the catalyst for both the coupling reactions and the magnetically recoverable feature of catalyst made this reaction highly desirable for industrial applications of present heterogeneous catalysis.
