The oxidation of hydrocarbons different structures under the same conditions is an important stage in study chemical properties both themselves and catalysts. In a 50% H2O2/Cu2Cl4·2DMG/CH3CN system, where DMG dimethylglyoxime (Butane-2,3-dione dioxime), at 50 °C or similar conditions, we oxidized eleven RH structures: mono-, bi- tri-cyclic, framework aromatic. To compare composition products th...

In this study synthesized and characterization of (1E,1'E)-2,2'-thiobis(1-(3-mesityl-3-methylcyclobutyl)ethan-1-one) dioxime for both experimental computational was reported. The solid-state FT-IR spectrum observed in the range 4000–400 cm-1 CDCl3 solvents were used 1H 13C NMR analysis. molecular geometry calculated using Density Functional Theory (DFT/B3LYP) method ground state with 6-31G(d, p...

The feasibility of using bis(delta2-2-imidazolinyl)-5,5'-dioxime (H2L) for the selective extraction of iron(III) from aqueous solutions was investigated by employing an solvent-extraction technique. The extraction of iron(III) from an aqueous nitrate solution in the presence of metal ions, such as cobalt(II), copper(II) and nickel(II), was carried out using H2L in binary and multicomponent mixt...

The resistance of Mycobacterium tuberculosis to isoniazid (INH) is largely linked to suppression of a catalase-peroxidase enzyme (KatG) that activates INH. In the absence of KatG, antioxidant protection is provided by enhanced expression of the peroxiredoxin AhpC, which is itself reduced by AhpD, a protein with low alkylhydroperoxidase activity of its own. Inhibition of AhpD might therefore imp...

We fabricated a thermostable quinoprotein aldose sugar dehydrogenase (tPQQ-ASD derived from a hyperthermophilic archaeon Pyrobaculum aerophilum) immobilized electrode. The electrode was prepared by immobilizing agarose gel mixed with the enzyme and carbon nanofiber (CNF) on a carbon paste (CP) electrode containing p-benzoquinone (BQ) as an electron mediator. The electrocatalytic response was ...
