Increasing the size of metalla-assemblies to target the EPR-effect of tumors and solid cancers

Mannancherril, Vidya ; Therrien, Bruno (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

Cancer, a malignant disease, is one of the leading causes of mortality and morbidity among humans. However, selective targeting of cancerous tissue remains challenging. The enhanced permeability and retention effect (EPR-effect), a naturally occurring phenomenon in solid cancerous tissue, is a suitable treatment pathway to selectively target cancerous tissues, whereas healthy tissue remains...

Hydrogen-bonded metalla-assemblies

Zhang, Fan ; Therrien, Bruno (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Hydrogen bonds are the most utilized non-covalent interactions in biological systems, due to their directionality, stability, reversibility and diversity. The weak strength of hydrogen-bond can be modified by combining several hydrogen bonds in the same unit, like in the melamine∙cyanuric/barbituric acid rosette-type system. Arene ruthenium metalla-assemblies have showed a great biological...

From anticancer complexes to photoswitchable assemblies : new approaches in the design and synthesis of arene ruthenium species

Cheminel, Thomas ; Therrien, Bruno (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2016.

The aim of the present thesis was to explore new approaches in the design and synthesis of new arene ruthenium species. This class of organometallic compounds has been the subject of much attention in the recent years due to their interesting properties in various fields, such as medicinal chemistry or supramolecular chemistry. In order to achieve this goal, this work was divided into two...

Insight into the rules dictating the formation of arene ruthenium metalla-assemblies

Garci, Amine ; Therrien, Bruno (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2015.

The self-assembly process is a natural phenomenon with the ability to organize biological systems. Its development by chemists as a synthetic process allowed the formation of esthetical structures as well as highly complex supramolecular systems with remarkable biological functions. Since 1990, metal directed self-assembly strategy has largely contributed to the design and synthesis of discrete...

Synthesis, characterization and exploration of the catalytic, supramolecular and biological applications of dinuclear complexes

Johnpeter, Justin Paul Raj ; Therrien, Bruno (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2013.

The work presented in this thesis involves the synthesis and characterization of dinuclear ruthenium, rhodium and iridium complexes. The catalytic, supramolecular and biological applications of these dinuclear complexes will be discussed. In the first part, the synthesis of sawhorse-type diruthenium tetracarbonyl complexes and their catalytic applications in the supercritical carbon dioxide...

Molecular arene ruthenium cages : new vectors to deliver drugs to cancer cells

Mattsson, Johann ; Therrien, Bruno (Dir.) ; Süss-Fink, Georg (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2010.

Ever since the discovery of cisplatin by Rosenberg in the 1970’s metal complexes as anti-cancer drugs have become an increasing subject of research. Ruthenium as a substitute for the toxic platinum metal has received a lot of attention recently. Organometallic compounds such as arene ruthenium complexes are very versatile and have proven to be active against cancer cells. In order to exploit...
