Self-assembly of proteins mediated by metal ions is crucial in biological systems and a better understanding and novel strategies for its control are important. An abiotic metal ion ligand in a protein offers the prospect of control of the oligomeric state, if a selectivity over binding to the native side chains can be achieved. Insulin binds ZnII to form a hexamer, which is important for its storage in vivo and in drug formulations. We have re-engineered an insulin variant to control its self-assembly by covalent attachment of 2,2?-bipyridine. The use of FeII provided chemoselective binding over the native site, forming a homotrimer in a reversible manner, which was easily followed by the characteristic color of the FeII complex. This provided the first well-defined insulin trimer and the first insulin variant for which self-assembly can be followed visually. Copyright

For enhancing the cetane number (CN) of diesel fraction, the selective oxidative ring opening method was applied to upgrade ring hydrocarbons. Organic acids, one of the main products from this oxidative reaction, being esterified by the phase transfer catalysis (PTC) approach were studied. Adipic acid, benzoic acid, and phthalic acid were used as model compounds. Reaction time, reaction temperature, the amount of water, and the amount of catalyst in the esterification process were investigated and optimized using orthogonal experimental design method. The kinetics of esterification process was then conducted under the optimal condition. The types of catalysts and organic acids, the amount of catalyst and water were also investigated. The PTC esterification was one rate controlling reaction on the interface between the aqueous phase and the oil phase. Hydrophobicity is a key factor for converting benzoic acid, adipic acid, and phthalic acid to the corresponding esters. It was found that around 5?8% water is the optimal quantity for the given reaction system. Two cases of esterification processes of PTC were proposed.

A new linear bismuth(III) coordination polymer, catena-poly[[chloridobismuth(III)]-mu3-1,10-phenanthroline-2,9-dicarboxylato-kappa6 O2:O2,N1,N10,O9:O9], [Bi(C14H6N2O4)Cl]n, has been obtained by an ionothermal method and characterized by elemental analysis, energy-dispersive X-ray spectroscopy, IR spectroscopy, thermal stability studies and single-crystal X-ray diffraction. The structure is constructed by Bi(C14H6N2O4)Cl fragments in which each BiIII centre is seven-coordinated by one Cl atom, four O atoms and two N atoms. The coordination geometry of the BiIII cation is distorted pentagonal-bipyramidal (BiO4N2Cl), with one bridging carboxylate O atom and one Cl atom located in the axial positions. The Bi(C14H6N2O4)Cl fragments are further extended into a one-dimensional linear polymeric structure via subsequent but different centres of symmetry (bridging carboxylate O atoms). Neighbouring linear chains are assembled via weak C – H?O and C – H?Cl hydrogen bonds, forming a three-dimensional supramolecular architecture. Intermolecular pi-pi stacking interactions are observed, with centroid-to-centroid distances of 3.678 (4) A, which further stabilize the structure. In addition, the solid-state fluorescence properties of the title coordination polymer were investigated.

In contrast to the plethora of catalytic systems that enable access to any enantiomers of the chiral products by simply choosing between a pair of enantiomeric or pseudoenantiomeric chiral catalysts, few analogously effective protocols exist for the synthesis of compounds bearing multiple stereogenic centers with full control of the absolute and relative stereochemical configurations. Here, we report the application of our previously developed modular phosphoramidite-thioether ligands for the copper-catalyzed diastereodivergent asymmetric 1,3-dipolar cycloaddition of azomethine ylides and nitroalkenes. Our catalytic system enables wide substrate scope, great stereochemical control, and high reaction efficiency.

In stark contrast to uranocene, (Cot)2Th reacts with neutral mono- or bidentate Lewis bases to give the bent sandwich complexes (Cot) 2Th(L) (L = py, 4,4?-bipy, tBuNC, phen, Me4phen). DFT calculations in the gas phase show that, for both U and Th, formation of the bent compound (Cot)2An(L) should be facile, the linear and bent forms being close in energy.

The activation of the beta-class carbonic anhydrases (CAs, EC 4.2.1.1) from the bacteria Brucella suis and Francisella tularensis with amine and amino acids was investigated. BsuCA 1 was sensitive to activation with amino acids and amines, whereas FtuCA was not. The most effective BsuCA 1 activators were L-adrenaline and D-Tyr (KAs of 0.70?0.95 muM). L-His, L-/D-Phe, L-/D-DOPA, L-Trp, L-Tyr, 4-amino-L-Phe, dopamine, 2-pyridyl-methylamine, D-Glu and L-Gln showed activation constants in the range of 0.70?3.21 muM. FtuCA was sensitive to activation with L-Glu (KA of 9.13 muM). Most of the investigated compounds showed a weak activating effect against FtuCA (KAs of 30.5?78.3 muM). Many of the investigated amino acid and amines are present in high concentrations in many tissues in vertebrates, and their role in the pathogenicity of the two bacteria is poorly understood. Our study may bring insights in processes connected with invasion and pathogenic effects of intracellular bacteria.

Two new dinuclear oxidovanadium(V) complexes, [V2O2(L1)(OCH3)2(CH3OH)2]·2(CH3OH) (1) and [V2O2(L2)(OCH3)2(CH3OH)2]·2(CH3OH) (2), were synthesized from the reaction of VO(acac)2 and hexa-dentate N2O4-donor hydrazone ligands (H4L1 and H4L2) in methanol solvent. The ligands and complexes were characterized by elemental analysis and spectroscopic methods. Single crystal X-ray analysis of the brown crystals of complexes 1 and 2 indicated that these complexes are dinuclear oxidovanadium(V) complexes which the metal ions have distorted octahedral geometry. There are several strong and directed hydrogen bonding interactions in the crystal packing of 1 and 2 which stabilize their crystalline format. The catalytic activity of these complexes was tested in the oxidation of thioanisole using H2O2. These studies indicated both complexes have high catalytic activity in the oxidation of thioanisole. The complexes were further studied by DFT and TDDFT theoretical calculations.

A series of N-aryl phosphoramidite ligands has been synthesized and applied to iridium-catalyzed allylic alkylation reactions, offering high regio- and enantioselectivities for a wide variety of substrates. These ligands feature the synthetic convenience and good tolerance of the ortho-substituted cinnamyl carbonates. Mechanistic studies, including DFT calculations and X-ray crystallographic analyses of the (pi-allyl)-Ir complexes, reveal that the active iridacycle is formed via C(sp2)-H bond activation.
