Two kinds of Fe–Co Prussian blue analogues (Fe–Co PBAs) with different iron valence state, Fe3[Co(CN)6]2·12H2O and Fe[Co(CN)6]·2H2O, were developed as the photo-Fenton catalysts for in-depth investigation of the heterogeneous Fenton reaction mechanism. These two catalysts showed exceptionall...

Macroporous cross-linked beads of styrene-divinyl benzene copolymer have been prepared with Schiff base (with one of its components as L-tyrosine) active sites on them. Cobalt palmitate has been chelated with these and the metal does not leach out under the reaction conditions of liquid phase ox...

In this paper, a core-shell multi-dimensional nanoarchitecture based on the uniform and well-aligned 0-dimension (0D) Co(OH)2 nanoparticles (NPs)/2-dimension (2D) Ni3S2 nanosheets (NSs) composites grown on 1-dimension (1D) SiC nanowire networks (NNs) skeletons with splendid resistances to oxidat...

A series of cobalt(II), cobalt(III) and mixed valence cobalt(II/III) compounds has been prepared and characterized. The protonated tripodal tetradentate ligand precursors (dimethylaminoethylamino-N,N-bis(2-methylene-4-tert-butyl-6-methylphenol), H2[O2NN′]BuMeNMe2, dimethylaminoethylamino-N,N-bi...

The action of a large excess of methylmagnesium iodide on cobaltous chloride results in formation of a colloidal suspension. This colloid decomposes iodomethane and the 1-halloctanes to give hydrocarbons derived from the Grignard reagent and hydrocarbons derived from the alkyl halide. From studi...

A convenient procedure for the preparation of cobaltic acetate in high yields by ozonation of cobaltous acetate in glacial acetic acid is described. Cobaltic acetate has an empirical formula Co2(OAc)4(OH)2(HOAc) and exists largely as a μ-hydroxo dimer in a glacial acetic acid. Cationic carboxyl...

In this study, a novel recyclable Co-doped UiO-66 nanoparticle was synthesized by a one-step solvothermal method. A high adsorption capacity of 224.1 mg g−1 was obtained by the CoUiO-1 nanoparticle, then the adsorbed tetracycline (TC) molecules could be removed more than 94% of initial concentra...

A series of metal chlorides were subjected to the wing spot test of Drosophila melanogaster. In the test, larvae trans-heterozygous for the wing-hair mutations mwh and flr were orally treated at the third instar stage with a test compound and the wings were inspected at the adult stage for spots...

The reactions of cis- and trans-2-lithio-2-butenes with cobaltous ion yield 3,4-dimethyl-2,4-hexadienes. The products are formed with essentially complete retention of stereochemistry. Neopentyl- and neophyllithium [(β,β-dimethylphenethyl)lithium] react with cobaltous ion to give unrearranged ...

Although a single dose of butylated hydroxytoluene (BHT); 1000 mg/kg to rats induced a hepatic injury accompanying centrilobular necrosis, the pretreatment with cobaltous chloride, an inhibitor of cytochrome P-450 synthesis, could inhibit the damage. The marked elevations of serum transaminase a...

Pyrroloisoquinolines formation through 5-endo halocyclization of unsaturated amides, direct C–H oxidative functionalization and N-acyliminium cyclization is described. A range of β-iodo-pyrrolidinones can be efficiently synthesized using this method, making it an excellent approach for constru...

We report two different synthetic approaches for the stereoselective synthesis of (2E,4E)-4-(4,4-dimethylpent-2-ynylidene)-N1,N5-dimethyl-N1,N5-bis(naphthalen-1-ylmethyl)pent-2-ene-1,5-diamine 1, an important impurity-reference standard for the chemical characterization of terbinafine. The diami...

The reaction of equimolecular amounts of (E)-N-(2,6-dichlorobenzylidene)(naphthalen-1-yl)methanamine (1) and Pd(OAc)2 in acetic acid at 60 °C for 24 h produced a selective palladation at the 2 position of the naphthyl group of 1, which afforded the new acetato-bridged five-membered cyclopallada...

A number of functionalized graphite oxides were prepared by treatment of graphite oxide (GO) with organic isocyanates. These isocyanate-treated GOs (iGOs) can then be exfoliated into functionalized graphene oxide nanoplatelets that can form a stable dispersion in polar aprotic solvents. Characte...

Simultaneous HPLC determination of the analgetic agent tramadol, its major pharmacodynamically active metabolite (O-desmethyltramadol) in human plasma is described. Simple methods for the preparation of the standard of the above-mentioned tramadol metabolite and N1,N1-dimethylsulfanilamide (used...

Drug combination for the treatment of pain is common clinical practice. Co-crystal of Tramadol-Celecoxib (CTC) consists of two active pharmaceutical ingredients (APIs), namely the atypical opioid tramadol and the preferential cyclooxygenase-2 inhibitor celecoxib, at a 1:1 molecular ratio. In thi...

To obtain potential A2A adenosine receptor agonists, a series of 2-hydrazinyladenosine derivatives were synthesized and assayed for adenosine receptors activity using radioligand binding activity assays. The binding activity of the subtypes was examined, and the structure-activity relationship o...

Rabbit muscle aldolase was found to be inactivated in a slow, reversible manner by D-erythrulose 1-phosphate. This compound combined rapidly and reversibly with the enzyme to form an initial complex, which then only slowly (ki = 0.28 min−1) converted to a kinetically more stable form. This stabl...

In this study, gene YALI0F01650g has been isolated and characterized. Several experimental evidences suggest that the identified gene, renamed EYD1, encodes an erythritol dehydrogenase. An efficient bioreactor process for the bioconversion of erythritol into erythrulose was also developed. Using...
