Synthesis of endoperoxides by domino reactions of ketones and molecular oxygen
(Royal Soc Chemistry, Cambridge, 2015)
Domino reactions of ketones with molecular oxygen in the presence of potassium hydroxide and potassium t-butoxide afford cyclic hydroperoxy acetals (3,5-dihydroxy-1,2-dioxanes). Mixed endoperoxides can also be obtained in ...
5-Aryl-1H-pyrazole-3-carboxylic acids as selective inhibitors of human carbonic anhydrases IX and XII
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Inhibitory activity of a congeneric set of 23 phenyl-substituted 5-phenyl-pyrazole-3-carboxylic acids toward human carbonic anhydrase (hCA, EC 4.2.1.1) isoforms I, II, IX and XII was evaluated by a stopped-flow CO2 hydrase ...
Simultaneous Determination of Pb and Cd Traces in Water Samples by Anodic Stripping Voltammetry Using a Modified GC Electrode
(Wiley-Blackwell, Malden, 2011)
The determination of Pb and Cd with a Nafion-modified glassy carbon electrode and Cu-DPABA complex (Cu-DPABA NA/GCE; DPABA is methyl 3,5-bis{bis-[(pyridin-2-yl)methyl]amino}methyl-benzoate) as an alternative electrode for ...
Voltammetric Behaviour and Determination of 8-Hydroxyquinoline Using a Glassy Carbon Paste Electrode and the Theoretical Study of its Electrochemical Oxidation Mechanism
(Electrochemical Science Group, Belgrade, 2011)
The 8-Hydroxyquinoline (8HQ) oxidation process has been investigated by Cyclic Voltammetry using a Glassy Carbon Paste Electrode (GCPE) as a working electrode. The theoretical study of the mechanism of electrochemical ...
Synthesis, characterisation and biological activity of Co(III) complex with the condensation product of 2-(diphenylphosphino)benzaldehyde and ethyl carbazate
(Elsevier Science Sa, Lausanne, 2013)
A cobalt(III) complex with the condensation derivative of 2-(diphenylphosphino) benzaldehyde and ethyl carbazate was synthesized. X-ray crystal structure was determined for both the ligand and the complex. In the cobalt(III) ...
Design of titanium nitride- and wolfram carbide-doped RGO/GC electrodes for determination of gallic acid
(Academic Press Inc Elsevier Science, San Diego, 2017)
In the present paper, the electrochemical behavior and the properties of two modified glassy carbon (GC) electrodes used for quantification of gallic acid in sweet wines were compared. A comparative study was conducted ...
Organocatalyzed synthesis of (-)-4-epi-fagomine and the corresponding pipecolic acids
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
The enantioselective synthesis of 4-epi-fagomine was accomplished starting from dioxanone and Cbz-protected benyzlamine, in 4 steps, with 18% overall yield. The key feature of this synthetic approach is the tactical ...
Quinoline based mono- and bis-(thio) carbohydrazones: synthesis, anticancer activity in 2D and 3D cancer and cancer stem cell models
(Royal Soc Chemistry, Cambridge, 2016)
A comparative study of antitumor activity of mono- and bis-quinoline based (thio) carbohydrazones was investigated by a series of tests on two human malignant cell lines: acute monocytic leukemia (THP-1) and pancreatic ...
Boron-doped diamond electrochemical sensor for sensitive determination of nicotine in tobacco products and anti-smoking pharmaceuticals
(Elsevier Science Sa, Lausanne, 2014)
A sensitive, selective and reliable electrochemical method for the determination of nicotine using differential pulse voltammetry on a bare boron-doped diamond electrode has been developed. Nicotine yielded a single oxidation ...
Didehydroroflamycoin pentaene macrolide family from Streptomyces durmitorensis MS405(T): production optimization and antimicrobial activity
(Wiley, Hoboken, 2013)
AimsThe aim of this study was to improve production of pentaene 32,33-didehydroroflamycoin (DDHR) in Streptomyces durmitorensis MS405 strain to obtain quantities sufficient for in depth analysis of antimicrobial properties. ...
