Potent and selective anticancer activity of half-sandwich ruthenium and osmium complexes with modified curcuminoid ligands

We have recently reported a series of half-sandwich ruthenium(ii) complexes with curcuminoid ligands showing excellent cytotoxic activities (particularly ionic derivatives containing PTA (PTA = 1,3,5-triaza-7-phosphaadamantane). In the present study, new m ...

Computational characterisation of the selectivity and binding mode of mono- and binuclear transition metal based anticancer compounds

Thibaud Edouard Alistair von Erlach

The rising resistance and the severe side effects associated with classical anticancer drugs such as cisplatin or mercaptopurines has triggered the development of novel antitumourous agents based on transition metal (e.g. ruthenium, osmium, and gold) organ ...

Palladium-Catalyzed Functionalization of Olefins and Alkynes: From Oxyalkynylation to Tethered Dynamic Kinetic Asymmetric Transformations (DYKAT)

Jérôme Waser, Stefano Nicolai, Bastian Antoine Rodolphe Claude Muriel, Ugo Jonathan Orcel, Mikus Purins, Phillip Gulliver Dominic Greenwood, Luca Buzzetti

This review presents an account of the palladium-catalyzed functionalizations of alkenes and alkynes developed at the Laboratory of Catalysis and Organic Synthesis (LCSO). Starting from the intramolecular oxy- and aminoalkynylation of alkenes, tethered met ...

Revealing the Mechanism of Doping of spiro-MeOTAD via Zn Complexation in the Absence of Oxygen and Light

Ulf Anders Hagfeldt, Yasemin Saygili, Hui-Seon Kim, Bowen Yang, Jiajia Suo

In this study, a new mechanism for doping of spiro-MeOTAD by Zn(TFSI)(2) is revealed, which is completely different from the mechanism induced by LiTFSI. The oxidation of spiro-MeOTAD is facilitated by complexation between the zinc cation and tert-butylpyr ...

In Situ Tethering Strategies for the 3-Component Synthesis of Vicinal Amino Alcohols and Diamines via Pd-Catalyzed Carboetherification and Carboamination

Ugo Jonathan Orcel

Vicinal amino alcohols and diamines are privileged motifs in organic chemistry. As such, they have been targets of choice for exploring and developing novel and more efficient strategies in organic synthesis. In this context, the difunctionalization of ole ...

Antiproliferative activity of ruthenium and osmium clusters with phosphine ligands

Paul Joseph Dyson, Alexey Nazarov

New ruthenium and osmium carbonyl clusters with 1,3,5-triaza-7-phosphatricyclo-[3.3.1.13.7]decane and 3,7-diacetyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane ligands were synthesized using Me3NO as an initiator. The data on antiproliferative activity of ne ...

Measurement of ammonia emissions from temperate and sub-polar seabird colonies

Julia Schmale

The chemical breakdown of marine derived reactive nitrogen transported to the land as seabird guano represents a significant source of ammonia (NH3) in areas far from other NH3 sources. Measurements made at tropical and temperate seabird colonies indicate ...
