A convenient method for the one-pot synthesis of long alkyl-chain triazolylglycosides using ionic liquid as dual promoter and solvent is described via a sequential one-pot two-step glycosidation-CuAAc click reaction. The reaction was carried out using com. available substrates, including glycosyl bromides, sodium azide and various long alkyl-chain alkynes to achieve the corresponding products in moderate to high yields. Furthermore, this approach was successfully applied for the preparation of non-ionic mono-catenary triazolylglycoside surfactants in excellent yields through simple deacetylation. Subsequently, these surfactants were further evaluated for their cytotoxic activity.

Kawamura, Kiana E.;Chang, Alison Sy-min;Martin, Daryl J.;Smith, Haley M.;Morris, Parker T.;Cook, Amanda K. research published 《 Modular Ni(0)/Silane Catalytic System for the Isomerization of Alkenes》, the research content is summarized as follows. Alkenes were used ubiquitously as starting materials and synthetic targets in all areas of chem. Controlling their geometry and position along a chain is vital to their reactivity and properties yet remains challenging. Alkene isomerization is an atom-economical process to synthesize targeted alkenes, and selectivity can be controlled using transition metal catalysts. The development of mild, selective isomerization reactivity has enabled efficient tandem catalytic systems for the remote functionalization of alkenes, a process in which a starting alkene is isomerized to a new position prior to the functionalization step. The key challenges in developing isomerization catalysts for remote functionalization applications are (i) a lack of modularity in the catalyst structure and (ii) the requirement of nonmodular and/or harsh additives during catalyst activation. The authors address both challenges with a modular (NHC)Ni(0)/silane catalytic system (NHC, N-heterocyclic carbene), demonstrating the use of triaryl silanes and readily accessible (NHC)Ni(0) complexes to form the proposed active (NHC) (silyl)Ni-H species in situ. Modification of the steric and electronic nature of the catalyst via modification of the ancillary ligand and silane partner, resp., is easily achieved, creating a uniquely versatile catalytic system that is effective for the formation of internal alkenes with high yield and selectivity for the E-alkene. The use of silanes as mild activators enables isomerization of substrates with a variety of functional groups, including acid-labile groups. The broad substrate scope, enabled by catalyst design, makes this catalytic system a strong candidate for use in tandem catalytic applications. Preliminary mechanistic studies support a Ni-H insertion/elimination pathway.

Herein, the authors report the synthesis, characterization and preliminary biol. evaluation of two novel silver(I) complexes of type [AgL₂](NO₃)₃ (3 and 4) with ionic N-donor benzimidazoles. The complexes have been synthesized by the reaction of 1.5 equiv of silver nitrate and N-donor benzimidazoles containing an imidazolium core at the 2-position (1 and 2) in ethanol. The X-ray anal. of 4 shows that it has two free imidazolium cores and the charge is balanced with three nitrate anions. A study by the combination of NMR, IR, LC-MS and elemental anal. techniques also suggests that the complexes have this structure both in the solid-state and solution The complexes are highly soluble and stable in water. Cytotoxicity evaluation against four cancerous human cells and one non-cancerous human cell revealed that the complexes have no significant anti-growth effect. However, the complexes showed a remarkable antimicrobial effect at normalized min. inhibitory concentrations (normalized MICs) in the range of 33-268μM against a panel of microorganisms consisting of Gram-neg. and Gram-pos. bacteria, and fungi.

Kang, Yanli;Zhang, Lu;Wang, Wenhao;Yu, Feng research published 《 Ethanol Sensing Properties and First Principles Study of Au Supported on Mesoporous ZnO Derived from Metal Organic Framework ZIF-8》, the research content is summarized as follows. It is of great significance to develop ethanol sensors with high sensitivity and low detection temperature Hence, we prepared Au-supported material on mesoporous ZnO composites derived from a metal-organic framework ZIF-8 for the detection of ethanol gas. The obtained Au/ZnO materials were characterized by X-ray diffraction (XRD), XPS, field emission SEM (SEM), field emission transmission electron microscopy (TEM) and nitrogen adsorption and desorption isotherms. The results showed that the Au/ZnO-1.0 sample maintains a three-dimensional (3D) dodecahedron structure with a larger sp. surface area (22.79 m² g^-1) and has more oxygen vacancies. Because of the unique ZIF structure, abundant surface defects and the formation of Au-ZnO Schottky junctions, an Au/ZnO-1.0 sensor has a response factor of 37.74 for 100 ppm ethanol at 250°C, which is about 6 times that of pure ZnO material. In addition, the Au/ZnO-1.0 sensor has good selectivity for ethanol. According to d. functional theory (DFT) calculations, the adsorption energy of Au/ZnO for ethanol (-1.813 eV) is significantly greater than that of pure ZnO (-0.217 eV). Furthermore, the adsorption energy for ethanol is greater than that of other gases.

H. research published 《 Hit-optimization using target-directed dynamic combinatorial chemistry: development of inhibitors of the anti-infective target 1-deoxy-D-xylulose-5-phosphate synthase》, the research content is summarized as follows. Target-directed dynamic combinatorial chem. (tdDCC) enables identification, as well as optimization of ligands for un(der)explored targets such as the anti-infective target 1-deoxy-D-xylulose-5-phosphate synthase (DXPS). We report the use of tdDCC to first identify and subsequently optimize binders/inhibitors of the anti-infective target DXPS. The initial hits were also optimized for their antibacterial activity against E. coli and M. tuberculosis during subsequent tdDCC runs. Using tdDCC, we were able to generate acylhydrazone-based inhibitors of DXPS. The tailored tdDCC runs also provided insights into the structure-activity relationship of this novel class of DXPS inhibitors. The competition tdDCC runs provided important information about the mode of inhibition of acylhydrazone-based inhibitors. This approach holds the potential to expedite the drug-discovery process and should be applicable to a range of biol. targets.
