Ces travaux décrivent l’utilisation d’ynamides et de N-allènamides comme intermédiaires clés pour la synthèse d’hétérocycles azotés et fluorés inédits. Une réaction de cyclisation intramoléculaire de mésyl N-allènamides trifluorométhylés promue par le TBAF a permis la synthèse de y-sultames trifluorométhylés alors que, l’utilisation d’un mélange TBAF/acide acétique, a permis l’obtention de y-sultames gem-difluorés. La formation de diènes trifluorométhylés substitués par une fonction amide, obtenue par une réaction de métathèse d’ène-ynamides avec un aldéhyde, a permis la synthèse de plateforme

Abstract:
Flavin adenine dinucleotide (FAD) is a coenzyme that participates in the redox process of flavoenzymes. Attempts to characterize the catalytic pathways of these enzymes have relied in part on the use of FAD chemical models. The efforts described in this dissertation focus on the chemical model approach to investigate the mechanism of the monoamine oxidase (MAO) catalyzed oxidation of the cyclic tertiary allylamine 1-methyl-4-(2-methyl-1H-pyrrol-2-yl)-1,2,3,6-tetrahydropyridine (TMMP), which is a close analog of the parkinsonian-inducing designer drug 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridin

Tissues constituting mammalian organisms are finitely organised 3-D multicellular structures where cell-cell and cell-matrix interactions are important modulators of functionality. The liver, being the site of metabolism in mammals, is extensively employed in in-vitro studies such as toxicology, drug testing and liver replacement. Most existing liver models have been static, homogenous 2-D models which have shown limited morphological and functional characteristics of in-vivo liver. With the improved understanding of the liver, these models became more sophisticated to comprise various liver a

Abstract:
Fourteen novel comb shaped amphiphilic polymers were successfully synthesised to determine the effect of polymer architecture on the potential of these amphiphilic polymers for hydrophobic drug delivery. Polyallylamine (PAA) was grafted with four different types of hydrophobic pendant groups (Cholesteryl (Ch), (Fmoc), (Dansyl)and (Naphth)). Some amphiphilic polymers were further reacted with methyl orange to form quaternary ammonium moieties. The polymers were characterised by elemental analysis and nuclear magnetic resonance spectroscopy (NMR). In the aqueous environment the amphiphilic polym

Increased degradation of IκBα was observed in allylamine-induced atherosclerotic vSMC phenotypes (henceforth referred to as allylamine cells).

Abstract:
Embryonic stem (ES) cells have the capacity to form any cell type. However, their propagation and differentiation is limited by current two dimensional (2D) culture techniques which offer little flexibility in terms of surface structure and functionalisation with bioactive molecules. The aim of the current work was to produce a novel scaffold that could manipulate ES cell behaviour using both architectural and biological cues. Electrospinning is a flexible technique that creates nonwoven meshes that mimic the fibrous architecture of the ECM. Initial work focused on investigating the suitabilit

In the first part of this study, frictional and normal forces in aqueous solutions were measured between a glass particle and oligopeptide films grafted from a glass plate. Homopeptide molecules consisting of 11 monomers of different amino acids were each "grafted from" an oxidized silicon wafer using microwave-assisted solid phase peptide synthesis. Oligopeptides increased the magnitude of friction compared to a bare hydrophilic silicon wafer. Friction was a strong function of the nature of the monomer unit and was lower for hydrophilic films. There was a strong adhesion and therefore fric
