L'objectif de ce travail de thèse a été de préparer de nouveaux dendrimères ou dendrons phosphorés, qu'ils soient neutres, cationiques ou anioniques, dans le but d'élargir le panel des applications dans le domaine de la nanomédecine en tant que molécules actives par elles-mêmes ou en association avec certains médicaments. Au chapitre 1, la synthèse d'un nouveau dendrimère phosphoré polycationique comportant en surface 5 groupements pyrrolidinium et une amine protonnée a été menée à bien. Ce dendrimère associé au microRNA-30d permet d'obtenir des polyplexes qui sont transférés dans les cellules

Abstract:

Dendrimers are a fairly new class of macromolecule. They have many potential uses including use in surface coatings and as host molecules. There are two main methods available for constructing dendrimers, the convergent approach and the divergent approach. In this thesis dendrimers were synthesised using the divergent approach. In chapter one our original aim was to synthesise dendrimers based on bicine, but there were complications involved in synthesis and storage of the monomer. However, it was possible to make a iminium salt using bicine as the starting material, which was reacted with var

A new family of aliphatic, polyurethane dendritic macromolecules has been designed, synthesised and characterised. The convergent route to dendrimers and the reactions of the selective coupling agent, carbonyl diimidazole (GDI) were employed.

The structure of the termini of these branched macromolecules was varied to consist of r-butyl, benzhydryl, cyclohexyl or 4-heptyl groups.

Polyarene dendrimers with rigid aromatic regions are of interest due to their shape persistent nature. A novel series of G1 dendrimers containing a substituted 1,3-phenyl core are reported and were found to exhibit atropisomerism. This was investigated in the solid state (X ray), in solution (NMR), and via computational studies. The synthesis of fluorinated G1 dendrimers allowed for the analysis of interconversion between conformations via 19F-19F EXSY NMR (exchange spectroscopy). These were shown to exist as two distinct sets of three interconverting atropisomers. Each atropisomer was identif

Abstract:

Malaria still remains one of the most dangerous widespread parasitic diseases in developing nations. Reported alarming figures of malaria infections annually highlight the âgapâ that remains to be filled to rid endemic of malaria. As cases of increasing spread of malaria and the emergence of resistance continue to exert pressure on health systems in most affected areas, novel antimalarial compounds are endlessly needed to overcome the problem of malaria infections. This thesis presents research investigating a series of thiosemicarbazones (TSCs) and their novel gold complexes and dendrimers as

Abstract:

Les nanotechnologies ont le grand potentiel de révolutionner des technologies classiques variées, dû au développement de nombreux nanodispositifs et ont été intensément étudiées durant la dernière décade. Parmi les nanoparticules utilisées, les dendrimères et dendrons appartiennent à ce "nano-monde" en vertu de leur taille nanométrique, qui peut être modifiée à volonté, ainsi que par exemple leur multivalence et leurs charges. A l'intérieur de l'espace dendrimère, les dendrimères phosphorés apparaissent comme étant parmi les systèmes dendritiques les plus utiles, grâce à l'extraordinaire réact
