    Influence of metal coordination on conductivity behavior in poly(butadiene-acrylonitrile)-CoCl2 system [Text] / O. V. Bushkova, I. P. Koryakova, Yu. A. Skorik, B.I. Lirova, A. V. Pestov, V. M. Zhukovskii // Electrochimica Acta. - 2008. - Vol. 53, № 16. - P5322-5333

Аннотация: The metal complex formation and the electrical properties of amorphous solid polymer electrolytes, based on poly(butadiene-acrylonitrile) copolymer (PBAN) and CoCl2, have been studied over the homogeneity region of the system limited by the CoCl2 concentration of 1.89 mol kg-1. It has been found that ionic conductivity is carried out by the unipolar anion transfer at lower CoCl2 concentrations (up to 0.10 mol kg-1). As the CoCl2 concentration increases, electronic conductivity appears in addition to ionic conductivity, and the former becomes dominant, starting from 0.38 mol kg-1. It has been shown that the nature of charge carriers is determined by the composition of metal complexes formed by CoCl2 and the macromolecular solvent PBAN. At lower concentrations, the [Co2L2Cl4]0 dimers are the predominant species (L being macromolecule side groups C{triple bond, long}N), and their dissociation is followed by the formation of mobile Cl- anions and immobile binuclear [Co2Cl3]+ complexes. As CoCl2 concentration increases, polynuclear [ConL2Cl2n]0 (n 2) complexes appear (L being C{triple bond, long}N and C{double bond, long}C groups of PBAN). Specific features of chemical bonds in ?-complexes of transition metals result in the appearance of electronic charge carriers. The abrupt increase in conductivity observed at the highest CoCl2 concentration is connected with the formation of a percolation network of polynuclear [ConL2Cl2n]0 complexes

ARSENIDE -- GABBRO -- ORE DEPOSITION -- ORE MINERALOGY -- SILVER
Аннотация: Ores rich in native silver at the Aktepe orefield near Tashkent, Uzbekistan, are similar to the arsenide-silver ores of the Cobalt-Gowganda region, Canada. The Aktepe ores occur as shoots and lenses in narrow fissures within a middle Paleozoic gabbro massif which is surrounded by Upper Paleozoic felsic volcanics and syenite intrusions. Widespread deuteric propylitization of the massif preceded ore deposition. The ore consists mainly of native silver, which is accompanied by native arsenic and bismuth, allargentum, dyscrasite, acanthite, numerous sulfides and sulfosalts, and by a Ni-Co-Fe arsenide and sulfarsenide assemblage similar to that of Cobalt-Gowganda. The Aktepe gangue minerals are mainly calcite, ferroan dolomite, and chlorite, and the veins are bordered by a wallrock-alteration assemblage of sericite-quartz-carbonate-pyrite. A difference from Cobalt-Gowganda is that the Aktepe carbonates are iron-rich, a feature which is attributed to a genetic relationship with the iron-rich host gabbros. -Authors????

Аннотация: The condensation of 4-hydroxy-3,5-diphenyl-2-phenyliminothiazolidine with 5-fluoro-4-morpholino- and 5-fluoro-4-(4-methylpiperazino)-1,2-phenylenediamines leads to region-isomeric thiazolo[3,4-a]quinoxalines differing in substituents in positions 7 and 8 of the benzene ring. From the ratio of isomers formed it follows that the mesomeric effect of a fluorine atom in 1,2-phenylenediamines is comparable with the influence of an aminosubstituent

Аннотация: Combination of the Suzuki cross-coupling and nucleophilic aromatic substitution of hydrogen (SNH) reactions proved to be a convenient method for the synthesis of 5-styryl-4-(hetero)aryl substituted pyrimidines from commercially available 5-bromopyrimidine. All intermediate 5-bromo-4-(hetero)aryl substituted pyrimidines and also the targeted 5-styryl-4-(hetero)arylpyrimidines were found to be active in micromolar concentrations in vitro against Mycobacterium tuberculosis H37Rv, avium, terrae, and multi-drug-resistant strain isolated from tuberculosis patients in Ural region (Russia). It has been found that some of these compounds possess a low toxicity and have a bacteriostatic effect, comparable and even higher with that of first-line antituberculosis drugs

PYRAZINES -- ANTITUBERCULOSIS ACTIVITY -- PETASIS REACTION
Аннотация: The Petasis reaction of 6-hydroxy adducts of 1-alkyl-2,3-dicyano-5-arylpyrazinium salts with trans-styrylboronic acids proved to proceed smoothly at room temperature to give the corresponding 5-(hetero)aryl-6-styryl substituted 1,6-dihydropyrazine derivatives. Also it has been found that C(6) unsubstituted 1,6-dihydro- or 1,4,5,6-tetrahydropyrazine derivatives can be easy prepared in high yields from the corresponding pyrazinium salts by reduction with triethylsilane. All synthesized compounds were screened in vitro for their antifungal activities against seven pathogenic fungal strains and antimycobacterial activities against Mycobacterium tuberculosis H(37)Rv, avium, terrae and multi-drug-resistant strains isolated from tuberculosis patients in the Ural region (Russia)

Аннотация: New 3-(1H-imidazol-2-yl)-9H-carbazoles and 6,6′-di(1H-imidazol-2-yl)-9H,9′H-3,3′-bicarbazoles have been prepared, starting from 9-ethyl-9H-carbazole-3-carbaldehyde or 9,9′-diethyl-9H,9′H-[3,3′-bicarbazole]-6,6′-dicarbaldehyde through their reactions with 4-methoxyaniline or 4-fluoroaniline, benzil or 2,2′-thenil [1,2-di(thien-2,2′-yl) glyoxal] and ammonium acetate on reflux in glacial acetic acid. The obtained compounds have been shown to demonstrate an effective fluorescence in the blue spectral region, exhibiting quantum yields in the range of 0.08–0.51, depending on their molecular structure and solvent polarity. The nature of the observed absorption spectra has been elucidated by the TDDFT calculations.

ULTRASONICATION -- 123-TRIAZOLE -- ANTIOXIDANT ACTIVITY
Аннотация: The perpetual demand of medicinally significant scaffolds has prompted the synthetic chemists to identify simple and efficient routes for flawless synthesis. A PEG-400:H2O mediated highly versatile, efficacious and selective “Click reaction” of fluorescent organic Probes under ultrasonic irradiation is reported. 1,2,3-Triazole ring has also been revealed to play a crucial role in bioorthogonal methodologies, fragment-based drug design, and biomolecular mimetics. This methodology provides a rapid and efficient approach for the synthesis of 1,4-Disubstituted 1,2,3-triazoles under Copper (I)-Catalyzed Azide-Alkyne [3 + 2] Cycloaddition (CuAAC) conditions in good to excellent yields in less time. This synthetic protocol has been proven to endorse easy work-up under benign reaction conditions. The green solvent system employed has been efficaciously reused several times without any loss of its activity in an aqueous medium. All the title compounds were characterized by using elemental analysis, 1HNMR, 13CNMR, FTIR, and mass spectral data. The newly synthesized compounds were biologically evaluated for their antioxidant activity. The antioxidant activity results demonstrate that all compounds showed good to excellent antioxidant activity, particularly the compounds 5d, 8 b, 8c and 8d exhibited promising radical scavenging activity. Further, photophysical properties of the compounds were accomplished using spectrofluorimeter. By this method, compounds 5c, 5e, 5f, 8a, 8 b, 8c and 8d exhibited fluorescence in the visible region. Molecular docking studies suggested the antioxidant activity of synthesized compounds due to the inhibition of neuronal nitric oxide synthase (HnNOS).
