Aromatic rings are found in a wide variety of products, including pharmaceuticals, agrochemicals, and functional materials. Diaryliodonium salts are new reagents used to transfer aryl groups under both metal-free and metal-catalyzed reactions and thereby synthesize arene-containing compounds. This minireview focuses on recent studies in selective aryl transfer reactions from unsymmetrical diaryliodonium salts under metal-free conditions. Reactions reported from 2007 to 2017, which represents a period of significant growth in diaryliodonium salt chemistry, are presented and organized by the type of reactive intermediate formed in the reaction. Specifically, reactions involving lambda(3)-iodane, lambda(3)-iodane radical anions, aryl radicals, and arynes are discussed. Chemoselectivity trends in aryl transfer are compared and contrasted across reaction intermediates and translation to potential auxiliaries are posited.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 98-10-2, you can contact me at any time and look forward to more communication. HPLC of Formula: https://www.ambeed.com/products/98-10-2.html.

Plant metabolites represent complex chemical system, which renders it difficult to clarify the chemical composition by conventional liquid chromatography/mass spectrometry (LC/MS) due to the limited selectivity and peak capacity. The rhizomes of Atractylodes macrocephala have been utilized as a traditional Chinese medicine Atractylodis Macrocephalae Rhizoma (Bai-Zhu), and have been reported containing multiple categories of plant metabolites. Targeting the multicomponents from A. macrocephala, an integral approach by offline two-dimensional liquid chromatography/ion mobility quadrupole time-of-flight mass spectrometry (2D-LC/IM-QTOF-MS) was established and validated. By configuring an XBridge Amide column of Hydrophilic Interaction Chromatography and an Atlantis Premier BEH Cl 8AX column of mixed ion exchange and reversed-phase modes, the established 2D-LC/IM-QTOF-MS system showed high orthogonality up to 0.91. Dimension-enhanced, data-independent high-definition MSE (HDMSE) in the positive ESI mode was conducted on a Vion IM-QTOF mass spectrometer, and its hyphenation to offline 2D-LC could enable the four-dimensional separation (each dimension in 2D-LC, IM, and MS). Particularly, HDMSE facilitated the acquisition of high-definition MS1 and MS2 spectra. In-house library-driven computational peak annotation by the bioinformatics platform UNIFI could efficiently process and annotate the HDMS E data for the structural elucidation. By integrating reference compounds comparison, we could identify or tentatively characterize 251 components from A. macrocephala (including 115 sesquiterpenoids, 90 polyacetylenes, 11 flavonoids, 9 benzoquinones, 12 coumarins, and 14 others), which indicated large improvement in identifying those minor plant components, compared with the conventional LC/MS approach. Conclusively, offline 2D-LC/IM-QTOF-HDMSE in combination with computational data interpretation proves to be powerful facilitating the in-depth multicomponent characterization of herbal medicine.

The recombinant polyhistidine-tagged hemoglobin I ((His)(6)-rHbI) from the bivalve Lucina pectinata is an ideal biocomponent for a hydrogen sulfide (H2S) biosensor due to its high affinity for H2S. In this work, we immobilized (His)(6)-rHbI over a surface modified with gold nanoparticles functionalized with 3-mercaptopropionic acid complexed with nickel ion. The attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) analysis of the modified-gold electrode displays amide I and amide II bands characteristic of a primarily alpha-helix structure verifying the presence of (His)(6)-rHbI on the electrode surface. Also, X-ray photoelectron spectroscopy (XPS) results show a new peak after protein interaction corresponding to nitrogen and a calculated overlayer thickness of 5.3 nm. The functionality of the immobilized hemoprotein was established by direct current potential amperometry, using H2S as the analyte, validating its activity after immobilization. The current response to H2S concentrations was monitored over time giving a linear relationship from 30 to 700 nM with a corresponding sensitivity of 3.22 x 10(-3) nA/nM. These results confirm that the analyzed gold nanostructured platform provides an efficient and strong link for polyhistidine-tag protein immobilization over gold and glassy carbon surfaces for a future biosensors development.

The mechanistic investigation of copper-catalysed transformations has been an important and fundamental task. Herein, we report via XAS and EPR spectroscopy that the sodium bis(trimethylsilyl)amide could reduce Cu(ii) to a Cu(i) species serving as an electron donor. XAS spectroscopy demonstrates that the newly formed Cu(i) species is the Cu[N(TMS)(2)](2)Na ate complex, in which the nitrogen atoms coordinate with copper linearly.

Reactive molecular dynamics was used to investigate the atomic-level mechanism of formic acid-accelerated deterioration of meta-aramid (PMIA) fibers. The simulation results showed that formic acid promoted PMIA decomposition. The activation energy of a composite system (PF) consisting of formic acid and PMIA was 106.94 kJ/mol at 2000-3000 K, which is 11.95% lower than that of pure PMIA. The main small-molecule products of the PF system were H/C/O-containing molecules (H2O, CO, and CO2), hydrocarbon molecules (e.g., CH4, (C2H)-C-center dot, C2H4, and C3H4), N-containing molecules (N-2, NH3, and HCN), H-2, and various free radicals. Formic acid can promote the production of small molecules such as CO, CO2, and H2O. The N-H bonds, C-N bonds and the amide C=O double bond of PMIA were vulnerable to CO, H ions, and free radicals produced by formic acid decomposition, and this decreased the PMIA stability. Temperature is an important factor in the thermal decomposition of PMIA and can accelerate reactions in the PF system. The initial reaction rate of PMIA at 3000 K was 8.1 times that at 2000 K, and the intermediate reaction rate was 6.2 times that at 2200 K; temperature also affects the types of pyrolysis products, for example, hydrocarbons are high-temperature products.

New anti-hepatocellular injury drugs with better curative effects and fewer side effects are urgently needed at present. In this study, a series of novel N-acetylcysteine (NAC) derivatives were designed, synthesized and biologically evaluated for their anti-hepatocellular injury activities against two different cell models. In the biological evaluation against hydrogen peroxide (H2O2)-induced LO2 hepatocytes, half of the target compounds exhibited moderate to potent activities in improving the model cell viability, and two compounds (6a and 6b) displayed more potent activities in decreasing malondialdehyde (MDA) levels than the positive control NAC. In further 4-acetamidophenol (APAP)-induced LO2 cell experiment, compounds 6a and 6b could not only improve the cell viability but also significantly reduce the secretion of MDA. Additionally, compound 6a displayed excellent Caco-2 permeability and oral bioavailability in rats. All these experimental results suggested that compounds 6a and 6b could serve as potential lead molecules for further development of anti-hepatocellular injury drugs.

The Cu(II) and Zn(II) binding abilities of Gly-His-Thr-Asp-amide (GHTD-am), a tetrapeptide coreleased from the pancreas along with insulin, were studied using UV-vis and circular dichroism spectroscopies, potentiometry, and calorimetry. GHTD-am is a very strong Cu(II) chelator, forming a three-nitrogen complex with a conditional affinity constant K-c at pH 7.4 of 4.5 X 10(12) M-1. The fourth coordination site can be occupied by a solvent molecule or a ternary ligand, such as imidazole, with K-c on the order of several hundred reciprocal molar. The Zn(II) binding ability of GHTD-am is relatively weak, with K-c values at pH 7.4 of 3.0 X 10(4) and 2.0 x 10(3) for the first and second GHTD-am molecule coordinated, respectively. These results are discussed in light of the modes of interactions of Zn(II) and Cu(II) ions with insulin. A direct effect of GHTD-am on the Zn(II) interactions with insulin is unlikely, but its Cu(II) complex may have a biological relevance because of its high affinity and ability to form ternary complexes.

Hollow fiber membranes consisting of polyethersulfone (PES) reformed with high proportions of -OH, aryl-N and alkyl-F groups in nonsolvent additives were compared for the removal of residual Cr (VI), COD, and bacteria from treated wastewater effluent by studying the underlying functional and molecular interactions during dope preparation and phase separation. These interactions were also studied and compared in the context of dope and membrane characteristics such as dope viscosity, membrane morphology, water contact angle, functionalities in the fabricated membranes, pure water permeability and rejection of residual solute. The membranes were characterized via Scanning Electron Microscopy (SEM), Fourier Transform Infrared (FT-IR) spectroscopy and Raman spectroscopy. For nonsolvent additives with -OH group, molecular weights and dope viscosity exhibited more impact on phase separation whereas for those with aryl-N and alkyl-F groups, phase separation was influenced by thermodynamic instability. Functional interactions also influenced the lumen shapes and membrane thickness. The lumens changed from spherical to elliptical-type shapes when aryl-amide and fluoroalkyl groups were added. Additives containing -OH group provided the highest contaminant rejection and the least flux whereas those containing aryl amide and fluoroalkyl groups enhanced the water permeability across the PES-based membranes but reduced the contaminant rejection. The PES membrane modified with -OH group was able to reduce residual contaminant concentrations from 14 ppb Cr(VI), 36.9 ppm COD, and 18,300 ppm total bacterial counts (TBC) to 8.3 ppb Cr(VI), 20.3 ppm COD, and 8601 ppm TBC with an intrinsic water permeability of 22.94 LMH/bar.

Sinapic acid (SNP) is a nutraceutical compound of hydroxybenzoic acid derivative which possesses antioxidant, anti-microbial, anti-inflammatory, anti-cancer, and anti-anxiety activity properties. In the present work, two cocrystals of SNP with two active drug ingredients such as Ethenzamide (ETZ) and 2-chloro-4-nitrobenzoic acid (CNB) are reported. Both the cocrystals were synthesized via simple solvent evaporation method and the crystal structures were characterized by Single Crystal X-ray Diffraction (SC-XRD) techniques. The cocrystals were formed via robust acid-amide heterosynthon and acid acid homosynthon between SNP and drug molecules. Both the cocrystals were crystallized in monoclinic crystal system with P 2(1)/c space group. The synthesized cocrystals were further characterized by DSC, PXRD, FT-IR, and H-1 NMR techniques. The solubility study in purified distilled water and in 0.1 N HCI solution demonstrate that there was no increment in the solubility of drug molecules in the cocrystals in both purified water and in 0.1 N HCl solution. The synthesized cocrystal exhibited six months stability at ambient conditions (similar to 25 degrees C, 60-65% RH). (C) 2018 Elsevier B.V. All rights reserved.
