Organometallic Cages as Vehicles for Intracellular Release of Photosensitizers

Schmitt, Frédéric ; Freudenreich, Julien ; Barry, Nicolas P.E. ; Juillerat-Jeanneret, Lucienne ; Süss-Fink, Georg ; Therrien, Bruno

In: Journal of the American Chemical Society (JACS), 2012, vol. 134, no. 2, p. 754-757

Water-soluble metalla-cages were used to deliver hydrophobic porphin molecules to cancer cells. After internalization, the photosensitizer was photoactivated, significantly increasing the cytotoxicity in cells. During the transport, the photosensitizer remains nonreactive to light, offering a new strategy to tackle overall photosensitization, a limitation often encountered in photodynamic...

Complexes arène-ruthénium multinucléaires fluctuants : véhicules pour le transport intracellulaire de molécules cytotoxiques et photosensibilisantes

Freudenreich, Julien ; Süss-Fink, Georg (Dir.) ; Therrien, Bruno (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2012.

Depuis plusieurs années, la thérapie photo-dynamique est pratiquée au quotidien pour soigner certaines tumeurs, comme le mélanome. La méthode consiste à traiter le patient au moyen d’un composé photosensible, indifféremment absorbé par les cellules normales et cancéreuses, ces dernières le retenant toutefois plus longtemps. Après plusieurs heures, le composé est activé par une...

Bimetallic ruthenium–tin chemistry: Synthesis and molecular structure of arene ruthenium complexes containing trichlorostannyl ligands

Therrien, Bruno ; Thai, Trieu-Tien ; Freudenreich, Julien ; Süss-Fink, Georg ; Shapovalov, Sergey S. ; Pasynskii, Alexandr A. ; Plasseraud, Laurent

In: Journal of Organometallic Chemistry, 2010, vol. 695, no. 3, p. 409-414

A series of neutral, anionic and cationic arene ruthenium complexes containing the trichlorostannyl ligand have been synthesised from SnCl2 and the corresponding arene ruthenium dichloride dimers [(η6-arene)Ru(μ2-Cl)Cl]2 (arene = C6H6, PriC6H4Me). While the reaction with triphenylphosphine...
