Charge control of fluorescent probes to selectively target the cell membrane or mitochondria: theoretical prediction and experimental validation

To achieve efficient and precise design of fluorescent probes, unraveling the intrinsic mechanism of their selectivity on different subcellular organelles in cell imaging is important. Using a theoretical protocol combining large-scale molecular dynamics simulations and the hybrid QM/MM model, we explored the mechanism of the strikingly different fluorescence imaging behaviors of two amphiphilic AIEgens with quite similar chemical structures. We proposed that the hydrophobic moiety and the pyridine group of AIEgens manipulate the emission behaviors, and the charged headgroups control the permeation ability through the cell membrane. Therefore, we proposed a molecular design strategy of AIEgen-based fluorescent probes to selectively target the cell membrane or mitochondria, and designed and synthesized four AIEgens. The cell imaging experimental results successfully confirmed the theoretical prediction, which would open an efficient shortcut to design AIEgen-based fluorescent probes to selectively target the cell membrane or mitochondria and lays a solid foundation for the rational design of advanced cell imaging materials.

Computational Study of Actinyl Ion Complexation with Dipyriamethyrin Macrocyclic Ligands

Relativistic density functional theory has been employed to characterize [AnO(2)(L)](0/-1) complexes, where An = U, Np, Pu, and Am, and L is the recently reported hexa-aza porphyrin analogue, termed dipyriamethyrin, which contains six nitrogen donor atoms (four pyrrolic and two pyridine rings). Shorter axial (An=O) and longer equatorial (An-N) bond lengths are observed when going from An(VI) to An(V). The actinide to pyrrole nitrogen bonds are shorter as compared to the bonds to the pyridine nitrogens; the former also play a dominant role in the formation of the actinyl (VI and V) complexes. Natural population analysis shows that the pyrrole nitrogen atoms in all the complexes carry higher negative charges than the pyridine nitrogens. Upon binding actinyl ions with the ligand a significant ligand-to-metal charge transfer takes place in all the actinyl (VI and V) complexes. The formation energy of the actinyl(VI,V) complexes in the gas-phase is found to decrease in the order of UO2L > PuO2L > NpO2 L > AmO2 L. This trend is consistent with results for the formation of complexes in dichloromethane solution. The calculated Delta G and Delta H values are negative for all the complexes. Energy decomposition analysis (EDA) indicates that the interactions between actinyl(V/VI) and ligand are mainly controlled by electrostatic components over covalent orbital interactions, and the covalent character gradually decreases from U to Am for both pentavalent and hexavalent actinyl complexes.

An affordable option to Au single crystals through cathodic corrosion of a wire: Fabrication, electrochemical behavior, and applications in electrocatalysis and spectroscopy

Faceting and nanostructuring of polycrystalline gold electrodes by cathodic corrosion in concentrated potassium hydroxide electrolytes has been systematically studied at different electrode potentials. Current-potential curves for the restructured Au electrodes in 0.1 M H2SO4 show characteristics of Au(111) in the double-layer and oxidation region. Thus, the modified Au electrodes adopt properties typically known for well-defined single crystal surfaces. Besides the preferential surface faceting, the electrochemically active surface area (EASA) is enhanced as a function of potential, concentration and time. Scanning electron micrographs show the formation of triangular pits and nanostructures with a specific orientation confirming the formation of (111)-facets. In this way, the behavior of single crystals is accompanied with the properties of nanoparticles which are of utmost interest in electrocatalysis and surface-enhanced Raman spectroscopy (SERS). The electrocatalytic activity of the newly formed Au(111) surface from an Au wire has been tested towards the hydrogen evolution reaction (HER) and for the formic acid oxidation reaction (FAOR). The study of electrocatalytic reactions at these nanostructured electrodes allows to identify active centers, which are absent for extended single crystal surfaces. Adsorbed pyridine on the nanostructured Au electrodes directly shows SERS activity, while untreated polycrystalline Au is SERS-inactive. The use of cathodic corrosion of simple wires is a paradigm of SERS-applications in electrochemistry with clean Au electrodes that provide properties of Au(111) single crystals.

Palladium catalyzed reductive Heck coupling and its application in total synthesis of (-)-17-nor-excelsinidine

Monoterpene indole alkaloids, bearing a highly substituted piperidine ring, are a structurally diverse class of bioactive natural products, found in various parts of the world. Herein, we reported the construction of the key piperidine ring via palladium catalyzed reductive Heck coupling with a good syn selective manner, avoiding the usage of stoichiometric, highly toxic, air sensitive and moisture sensitive Ni(COD)(2). To further showcase the value of this methodology, we realized the total synthesis of the structurally unique zwitterionic monoterpene indole alkaloid (-)-17-nor-excelsinidine in 9 steps, in which the key ammonium-acetate connection (N4-C16) of (-)-17-nor-excelsinidine was constructed via oxidative coupling in excellent yield and high regioselectivity under NBS/pyridine from the enolate of geissoschizine.

Formic Acid-Assisted Selective Hydrogenolysis of 5-Hydroxymethylfurfural to 2,5-Dimethylfuran over Bifunctional Pd Nanoparticles Supported on N-Doped Mesoporous Carbon

Biomass-derived 5-hydroxymethylfurfural (HMF) is regarded as one of the most promising platform chemicals to produce 2,5-dimethylfuran (DMF) as a potential liquid transportation fuel. Pd nanoparticles supported on N-containing and N-free mesoporous carbon materials were prepared, characterized, and applied in the hydrogenolysis of HMF to DMF under mild reaction conditions. Quantitative conversion of HMF to DMF was achieved in the presence of formic acid (FA) and H-2 over Pd/NMC within 2 h. The reaction mechanism, especially the multiple roles of FA, was explored through a detailed comparative study by varying hydrogen source, additive, and substrate as well as by applying in situ ATR-IR spectroscopy. The major role of FA is to shift the dominant reaction pathway from the hydrogenation of the aldehyde group to the hydrogenolysis of the hydroxymethyl group via the protonation by FA at the C-OH group, lowering the activation barrier of the C-O bond cleavage and thus significantly enhancing the reaction rate. XPS results and DFT calculations revealed that Pd2+ species interacting with pyridine-like N atoms significantly enhance the selective hydrogenolysis of the C-OH bond in the presence of FA due to their high ability for the activation of FA and the stabilization of H-.

Halogenated imidazo[1,5-alpha]pyridines: chemical structure and optical properties of a promising luminescent scaffold

A series of halogenated imidazo[1,5-alpha]pyridines was prepared and their structural and optical properties investigated. The products were characterized by spectroscopic techniques and their optical properties discussed in relation to their chemical structure. We were able to triplicate the luminescence quantum yields (phi) in solution for three different imidazo[1,5-alpha]pyridine derivatives, depending on the halogen nature of the substituent on the imidazo[1,5-alpha]pyridine moiety. The effect of the halogen and of the geometrical and chemical characteristics of the molecular skeleton on the crystal packing was studied in the solid state by single crystal X-ray diffraction. At the same time, the possible presence of halogen bonds was evaluated through solid-state NMR analysis.

Metallo-supramolecular Crosslinked Polyurethanes

The effects of incorporating metal-binding ligands as chain extenders in polyurethane elastomers were investigated. Segmented polyurethanes based on 2 kDa poly(tetramethylene oxide) (PTMO) and 4,4-methylenebis(cyclohexyl isocyanate) were polymerized using a two-step process in which 2,6-bis(1-ethyl-5-(methoxymethyl)-1H-benzo[d]imidazol-2-yl)pyridine was added as a chain extender. The resulting polyurethanes were then metallated using stoichiometric amounts of Zn(II) metal salts with different counterions. The resulting metallopolymers have substantially improved Young’s moduli, increased failure stress, and improved thermomechanical behavior. The materials were microphase-separated into anisotropic hard domains within a PTMO matrix. Simultaneous small-angle X-ray scattering and tensile testing revealed the minority hard segment domains remain relatively intact during elongation, likely due to the strength of the metal-ligand complex.

Nickel-mediated cross-coupling via C-O activation assisted by organoaluminum

We report the alkylation and arylation cross-coupling of aryl ethers based on C-O bond activation using a nickel catalyst and organoaluminum reagents. Ni(cod)(2) in combination with 1,2-bis(dicyclohexylphosphino)ethane ligand in toluene solution at 130 degrees C are the best conditions. The naphthyl ether or methoxy pyridine derivatives are suitable substrates for alkylation and arylation reaction with a wider scope of aluminum reagents in good yields. Computational analysis on the pyridine substrate is provided to help delineate the mechanistic pathway and demonstrate the important aspects of the cooperative interaction bimetallic catalysis. First, the coordination of AlMe3 to the O atom of pyridine is essential for C-O activation. Second, the beta-H transfer from methoxy to pyridine could be discouraged through the use of bidentate phosphine as a ligand. Finally, excess AlMe3 reagent is critical for facilitating a reductive elimination process.

Crystal structure, Hirshfeld surface analysis and contact enrichment ratios of 1-(2,7-dimethyl-imiciazo[1,2-a]pyridin-3-yl)-2-(1,3-dithioian-2-yl-idene)ethanone monohydrate

In the title hydrated hybrid compound C14H14N2OS2 center dot H2O, the planar imidazo[1,2-a]pyridine ring system is linked to the 1,3-dithiolane moiety by an enone bridge. The atoms of the C-C bond in the 1,3-dithiolane ring are disordered over two positions with occupancies of 0.579 (14) and 0.421 (14) and both disordered rings adopt a half-chair conformation. The oxygen atom of the enone bridge is involved in a weak intramolecular C-H center dot center dot center dot O hydrogen bond, which generates an S(6) graph-set motif. In the crystal, the hybrid molecules are associated in R-2(2) (14) dimeric units by weak C-H center dot center dot center dot O interactions. O-H center dot center dot center dot O hydrogen bonds link the water molecules, forming infinite self-assembled chains along the b-axis direction to which the dimers are connected via O-H center dot center dot center dot N hydrogen bonding. Analysis of intermolecular contacts using Hirshfeld surface analysis and contact enrichment ratio descriptors indicate that hydrogen bonds induced by water molecules are the main driving force in the crystal packing formation.
