Compound 1000 times more effective than first choice drug for parasitic disease

Scientists in Mexico have devised a new synthetic pathway to a nitrogen-containing ligand, which, when bound to divalent nickel or manganese, is a 1000 times more effective than the leading clinical drug at reducing the profileration of the parasite responsible for amoebiasis. This disease causes 70 thousand deaths a year.

Potential cytotoxic and amoebicide activity of first row transition metal compounds

The same ligand bound to other divalent metal ions also shows remarkable anti-cancer properties with activities superior to cisplatin.

Dalton Transactions is now welcoming submissions for a themed issue in N-heterocyclic carbenes, guest edited by Dr Catherine Cazin from the University of St Andrews.

Submission deadline: 28th November 2012

N-Heterocyclic carbenes (NHCs) have become ubiquitous in coordination and organometallic chemistry and have had profound impact in homogeneous catalysis. This class of ligands has attracted significant attention during the last fifteen years, with hundreds of papers published every year, and four books dedicated to the topic. This Dalton Transactions themed issue will seek to highlight to the inorganic research community the latest and very best research in the field ranging from synthetic to applications-oriented contributions.

All article types will be considered – Communications, Full Papers, Frontiers and Perspectives. See our author guidelines for more information.

Click here to submit

Please note that inclusion in the themed issue will be subject to the guest editor’s discretion. All manuscripts will undergo peer-review in accordance with the Dalton Transactions mandate.

For enquiries, please contact the Editorial Office.

Delivering cancer-combatting compounds

caged pyrenyl arene ruthenium complexScientists from Switzerland have developed a cage-encapsulated ruthenium complex for killing cancer cells.

The multifunctional drug has several features providing it with it’s fantastic anti-cancer properties… 1)  it’s ruthenium based instead of platinum (less toxic and has been shown to overcome certain resistance mechanisms induced by Pt); 2) the pyrenyl ligands can easily intercalate with the DNA base pairs; and 3) the metalla-cage bestows water-solubility on the drug therefore enabling it to be internalised within the cancerous cells.

Not only that, the pyrene moiety is fluorescent so the uptake of the drug into the cell can be recorded in action.

Cellular delivery of pyrenyl-arene ruthenium complexes by a water-soluble arene ruthenium metalla-cage

Bimetallic tuneable MOFs – a one-pot wonder

Laurance Beauvais and colleagues have synthesised a mixed metal MOF allowing different divalent metal ions to be easily incorporated into the framework. A bimetallic approach means that one metal can be used for structural integrity, whilst the other can be functional, for application in catalysis for example. The team chose a porprhyrin-based ligand to underpin the framework since this has two distinct metal binding sites – a structural metal binding site at the carboxy and pyridyl ligands; and a functional metal binding site within the porphyrin cavity.

mixed metal porphyrin

By adding the metals together in a one-pot reaction, the porphyrin framework incorporates both metals with the larger metal ions occupying the structural sites.

With the synthetic method now done and dusted, the team will now look into the catalytic and luminescent properties of these coordination framework materials.

Nanocatalyst for hydrogen release

hydrogen release from the dimethlyamine-borane complexAmine borane complexes are a promising solution for storing hydrogen, particularly as we move towards a hydrogen economy. Whilst focusing on developing the dehydrogenation of such complexes (namely dimethylamine-borane), scientists from Turkey have shown that you need to think small to think big by preparing a nanoparticle catalyst for the reaction.

By adding ruthenium (III) chloride to the hydrogen storing dimethlyamine-borane complex, the team found that ruthenium nanoparticles are generated in-situ which further work to catalyse the release of hydrogen from the complex.

Nanosizing the catalyst means a higher proportion of surface atoms are available for the hydrogen-storage complex – the result is greater catalytic activity and faster hydrogen generation.
