Texto completoThis thesis is dedicated to the generation of the virtual space of 2.5K DNA-encoded libraries and its detailed structural and property chemoinformatic analysis. GTM-based methodologies allowing to quickly compare and select optimal DELs out of thousands of possible ones based on the structural or property similarity to a reference database were developed. The problem of combinatorial compound enumeration was addressed by developing a highly performant deep learning model capable of predicting the position of a compound on the GTM based solely on its building blocks and reactions, skipping compound enumeration. Machine learning models allowing to predict the reactivity of building blocks and activity of DEL compounds were created. The latter coupled with GTM visualization, allowed to rationalize and facilitate the reagent selection for DEL synthesis and hit prioritization

Texto completoGlycans are essential biomolecules found in every living system. The recent advent of chemical biology paved the way for great advances in glycobiology such as metabolic glycan engineering (MGE). This strategy consists in the use of a modified monosaccharide, the chemical reporter, which can enter the cell and hijack the metabolic pathway. Upon incorporation, the introduced chemical reporter detection is achieved in a specific manner through bioorthogonal ligation. The present work aims to study sialic acids, which are often found at the outermost position of glycan chains:(i) we developed an original MGE-based strategy, using two different chemical reporters, each one being an analog of products from different steps of the biosynthetic pathway. This sequential bioorthogonal dual strategy (SBDS) has provided new insights in the entry mechanisms of both sialic acid and its precursor N-acetylmannosamine. (ii) we introduced chemically modified sialic acids, but, this time in an exo-enzymatic way, with specific glycosyltransferases (sialyltransferases) onto soluble glycoproteins or living cells. Before being transferred, sialic acids need to be activated as CMP-sialic acids which are very unstable and prone to decomposition. 31P NMR was used to optimize the production of ready-to-use CMP-sialic acids providing a versatile, simple and reproducible procedure. Natural and/or unnatural CMP-sialic acids have then proven to be great tools for the study and characterization of different enzymes. More than just a tool-box, this work describes some direct applications of our chemical tools to unravel cellular pathways, enzymatic reactions, or even biosynthesis defects

Texto completoProtein-protein interactions (PPI) represent a wealth of potential therapeutic targets. However targeting them with synthetic compounds represent a major challenge. The aim of this thesis was to find a way to overcome these challenges by studying the physicochemical profile of PPI inhibitors (aka chemical space). We firstly manually collected structures, pharmacological and physicochemical profiles of inhibitors of PPI (iPPI) in a database named iPPI-DB. Then, we identified new iPPI properties to favour and that did not preclude further drug development. Indeed, 4 descriptors were found specific to iPPI and that do not rely on the hydrophobicity and on the size. They represent either the 3D shape of the compounds or the distribution of their hydrophobic/hydrophilic interacting regions. This opens new ways to design and select iPPI. In a second analysis, we further validated these properties on larger datasets and address the disparity between PPI families. We could demonstrate that comparable classes of PPI targets can identified using separately their target- or their ligand-space. This analysis may help to prioritize the desired physicochemical properties of iPPI using class-specific profiles. Finally, using a combination virtual screening and cell viability assay, we were able to identify 6 compounds that inhibit the interaction between TRAIL and DR5 implied in HIV (human immunodeficiency virus)

Texto completoDe nombreux travaux ont montré que, à l'origine des limitations de l'interaction bureautique, il y a un manque à la fois d'espace moteur et d'espace visuel. Cette thèse explore des moyens pour optimiser l'usage de ces espaces. D'une part, à partir du constat que l'on contrôle la position et l'orientation d'un objet par un geste naturel, cette thèse étudie les bénéfices que peut offrir une souris dotée d'un capteur de rotation. Cette "souris rotative" permet à l'utilisateur de maîtrise avec aisance trois variables continues d'une tâche informatique. Un état de l'art présente des aspects perceptifs et moteurs des actions en question et les particularités ergonomiques et techniques d'un tel dispositif. Deux techniques d'interaction - visant à faciliter des tâches métier récurrentes- sont proposées : le réglage "quasi-intégral" et la "palette satellitaire". Par ailleurs, une évaluation expériemntale compare la performance d'une souris rotative avec celle d'une souris traditionnelle. D'autre part, ce travail se penche sur les questions de la visualisation de documents dans le contexte des bibliothèques numériques. D'abord, il examine l'apport et la faisabilité technique de l'utilisation d'un dispositif d'affichage immersif pour la navigation dans un catalogue de titres virtuel. Puis, afin de faciliter l'inspection massive d'un lot de pages numérisées, il avance des techniques de visualisation zoomables et multifocales. Ces dernières permettent, dans une recherche d'anomalies, de saisir vite les carctéristiques visuelles de quelques centaines de pages. Et cela grâce à un va-et-vient entre la vue d'ensemble et la navigation panoramique des détails

Texto completoTo date, terpenoids form the most abundant and diversified class of natural products with more than 80,000 compounds whose structural, biological (antibiotic, anticancer, antimalarial, etc.) and physicochemical (flavor, fragrance, dye, etc.) properties hold the attention of the scientific community. However, their access is limited because of the low available quantity by extraction from natural sources; an often expensive and laborious chemical synthesis; and long biosynthetic pathways. By combining bioinformatic, statistical, biochemical and molecular biology approaches, we have developed the « Terpene mini-path », with only two enzymatic steps, as a synthetic and potentially bio-sourced alternative to access DMAPP and IPP, universal precursors of terpenes. This new artificial pathway allowed the synthesis of various natural and unnatural terpenoids, such as cyclobutylic derivatives, in the absence of any metabolic and enzymatic engineering. The mini-path provides thus an easy access to all terpenoids and represents an attractive new biosynthetic tool to explore the diversity of the terpene chemical space

Texto completoThanks to the development of a new generation of instruments such as IMG (spectral resolution of 0. 1 cm-1), AIRS (spectral resolution of 1 cm-1), IASI (spectral resolution of 0. 5 cm-1) and GOSAT (spectral resolution of 0. 4 cm-1), the potential of sounding the tropospheric composition from space in the thermal infrared has improved considerably. In the thermal infrared profiles of tropospheric trace gases can be retrieved day and night (with or without reflected/backscattered solar photons) with more than one piece of information for an instrument with a spectral resolution of about 0. 1 cm-1. When the reflected/backscattered solar flux is measured in the shortwave infrared (SWIR), only a total column can be derived. The TIR-SWIR is thus potentially very interesting as the TIR provides information on the vertical distribution (with a small sensitivity near the surface) and the SWIR provides a precise total column (without clouds and only in the daylight). The goal of this PhD work is to quantify by simulation using a radiative transfer model and an adequate inversion scheme (based on the optimal estimation method) the performances of the TIR-SWIR combination for different species – carbon monoxide (CO) and methane (CH4) – and different instrument characteristics (signal to noise ratio, spectral resolution…)

Texto completoMagnetic Resonance Imaging (MRI) is currently the visualization technique that surgeons preferentially choose. However this technique does not allow the visualization of polymer-based prosthesis, whether they are degradable or not. In order to best assess adhesion, tissue integration and the future of implantation of these polymer prosthesis, it would be advisable to make them visible in IRM. This work presents the conception and the synthesis of biocompatible copolymers visible in IRM meant to be implanted under the form of prosthesis for temporary or permanent applications. Using the chemical modification in alpha position of ester function, previously described by our laboratory, we grafted a gadolinium chelate, in a covalent way and forming a stable bond on PCL (degradable) and PMA (non degradable) backbone. Gadolinium was then complexed by DTPA previously grafted. Those new copolymers were characterized with NMR and SEC, and the rate of gadolinium was assessed by ICP-MS. MRI images were taken in vitro and in vivo on devices containing 7-Teslas (research) and 1,5 Teslas (clinical) magnets. These images show a poly(propylene) mesh coated with grafted copolymer containing complex gadolinium which is visible in MRI. It will consequently improve the prospects of applications for this kind of MRI-visible compound
