When we consider the concepts metal and catalysis, we tend to assume quite matter-of-factly that the metal will be the catalyst. This assumption is based on the fact that metals can be found in reactions where they act as catalysts or co-catalysts in the form of coordination and organometallic compounds, nano-sized or bulk materials and […]

There are instances in which you would intentionally deliver nanoparticles to animals (humans included). Contrast agents for medical diagnosis or therapeutic ones for medical treatments are two examples. It is also the case with plants, as some fertilizers take the form of nanoparticles. Unintentional exposure of animals or plants to nanoparticles is also possible: environmental […]

Catalysis-based approaches for the activation of anticancer rely on the use of metal catalysts capable of deprotecting inactive precursors of organic drugs or transforming key biomolecules available in the cellular environment. Nevertheless, the efficiency of most of the schemes described so far is rather low, limiting the benefits of catalytic amplification as a strategy for […]

Auranofin is a gold (Au) salt classified by the World Health Organization as an antirheumatic agent. It was approved for the treatment of rheumatoid arthritis in 1985, but is no longer a first-line treatment due to its adverse effects on a long-term basis. But the drug is important in another way. The discovery that auranofin […]

A catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. As the catalyst itself takes part in the reaction it may undergo a physical change. Metal complexes are typically regarded as catalysts that convert organic substrates into more valuable compounds; however, to date, catalytic transformations […]

Metal complexes are typically regarded as catalysts that convert organic substrates into more valuable compounds; however, to date, catalytic transformations of metal complexes are practically unknown and represent a complete new way of thinking in catalysis. Their development can expand the scope of bioorthogonal chemical reactions to inorganic substances and metal-based prodrugs, fostering the creation […]

The combination of catalysis and bioorthogonality promises have an impact on drug discovery and bioimaging. Bioorthogonality, a term coined by Carolyn R. Bertozzi in 2003, refers to any chemical reaction that can occur inside of living systems without interfering with native biochemical processes. Hence, catalytic turnover can boost the efficiency of bioorthogonal chemical reactions, unveiling […]
