Electrochemical Synthesis of a Binary Mn-Co Oxides Decorated Graphene Nanocomposites for Application in Nonenzymatic H2O2 Sensing

International Journal of Electrochemical Science, 2017
In this work, binary metallic oxides of MnO2-Co3O4 nanocomposite was electrodeposited on graphene oxide (GO) modified electrode by a facile and one-step electrochemical method. The resultant MnO2-Co3O4/graphene (MnO2-Co3O4/GP) electrode was characterized

Cyclic Conversion of the Novel Src Kinase Inhibitor TG100435 and Its N‐Oxide Metabolite by Flavin‐Containing Monoxygenases and Cytochrome P450 Reductase

The FASEB Journal, 2008
TG100435 is a novel multi‐targeted Src family kinase inhibitor with demonstrated anticancer activity in preclinical species. Potent kinase inhibition is associated with TG100435 and its major N ‐oxide metabolite TG100855. The objectives of the current study were to identify the hepatic enzyme(

AscF in the mycobacterial CIII–CIV supercomplex lacks metal and nucleotide binding but links malate oxidation to respiration

FEBS Letters, EarlyView.
The mycobacterial CIII‐CIV respiratory supercomplex is an obligate assembly, encompassing several subunits of unknown functions. We have characterized the intracellular subunit AscF, and show that it is unlikely to be a sensor for metals or nucleotides, but is required for growth on nonfermentable energy sources, and likely works as an adapter for ...

Site-Specific Oxidative C–H Chalcogenation of (Hetero)Aryl-Fused Cyclic Amines Enabled by Nanocobalt Oxides [PDF]

, 2018
By employing reusable nanocobalt oxides as the catalysts, a site-specific oxidative C–H chalcogenation of (hetero)­aryl-fused cyclic amines with various thiols and diselenides is presented for the first time.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Diversity and functional analysis of LuxR-type transcriptional regulators of cyclic lipopeptide biosynthesis in Pseudomonas fluorescens [PDF]

, 2009
Cyclic lipopeptides (CLPs) are produced by many Pseudomonas species and have several biological functions, including a role in surface motility, biofilm formation, virulence, and antimicrobial activity.

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Thermal rearrangements of cyclic amine ylides. IV. Rearrangement of .BETA.,.GAMMA.-unsaturated 1-alkylpiperidine N-oxides: Formation of 1,2-oxazepine derivatives.

Chemical and Pharmaceutical Bulletin, 1984
The thermolysis of 1-methyl-2-vinylpiperidine N-oxide (13) resulted in Meisenheimer [1, 2] rearrangement to give the hexahydro-1, 2-oxazepine (23) and no [2, 3]-sigmatropic rearrangement product (24). Similarly, the 1-methyl-1, 2, 5, 6-tetrahydropyridine N-oxides (15), on heating, gave only the tetrahydro-1, 2-oxazepines (26, 27), together with the ...
