To be or not to be NO in coordination chemistry? A mechanistic approach

Coordination Chemistry Reviews, 2002
Abstract In this review, the reactions of nitric oxide with selected metal complexes of biological and environmental importance are reviewed. Fundamental chemical kinetics and mechanisms that lead to the formation and decay of nitrosyl complexes are illustrated and discussed on the basis of work on Fe(II) chelate complexes and selected biomolecules ...

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 ...

Synthesis, coordination chemistry, and cooperative activation of H 2 with ruthenium complexes of proton-responsive METAMORPhos ligands [PDF]

, 2014
The synthetic scope of proton-responsive sulfonamidophosphorus (METAMORPhos) ligands is expanded and design principles for the selective formation of particular tautomers, ion pairs, or double condensation products are elucidated. These systems have been

The Homocoupling Reaction of Aromatic Terminal Alkynes by a Highly Active Palladium(II)/AgNO3 Cocatalyst in Aqueous Media Under Aerobic Conditions

Molecules, 2016
A new and efficient Pd(II)/AgNO3-cocatalyzed homocoupling of aromatic terminal alkynes is described. Various symmetrical 1,4-disubstituted-1,3-diynes are obtained in good to excellent yields.

The therapeutic opportunities and pitfalls of using iron ion chelators to treat neurodegenerative diseases

FEBS Letters, EarlyView.
Although too much iron in the brain promotes neurodegeneration, iron ion chelators have had mixed effects in clinical trials. This review explains why; some chelators do not render the iron redox‐inactive (e.g., L1) whereas others do (e.g., desferrioxamine).

'Click' Chemistry in Coordination and Supramolecular Chemical Applications [PDF]

The term “click chemistry” was first coined by Sharpless and co-workers in 2001 and encompasses a range of high yielding organic coupling reactions which are rapid, highly selective and proceed with good functional group tolerance.

Coordination polymers utilizing N-oxide functionalised host ligands [PDF]

, 2012
Pyridyl functionalized host molecules are oxidized to their N-oxide analogues and form a series of coordination polymers and discrete complexes with transition metal cations.

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 ...

Cadmium: Coordination Chemistry [PDF]

, 2014
The coordinative behavior of cadmium(II) is typical of a soft acid. Evidence of this fact is its strong interactions with S2− and HS− groups leading to the formation of highly stable complexes. Interactions with ligands containing oxygen-donor groups are
