Testo completoAlkaloids are widely occurring compounds in nature. The increasing scope of pharmacological properties displayed by the alkaloids extracted from a neotropical frog Dendrobates pumilio has arouse an intense interest in their study, both from a synthetic and biological aspect. The interest toward the alkaloid (-)-205B has not been considered in our laboratory solely because of the challenged 8b-azaacenaphthylene ring structure, but also was inspired by the promising biological activity it might possess against neuronal disorders.An efficient and highly stereoselective synthetic strategy was developed for the synthesis of the alkaloid (-)-205B. This approach features three characteristic transformations for building up the tricyclic core and installing the main stereochemistry: a 2+2 cycloaddition, a vinylogous Mannich reaction and an aza-Prins cyclization. In tandem with this total synthesis, a novel methodology was developed focusing on the stereo-directed alkylation based on silicon-tethered chemistry that comes up as an efficient solution for a difficulty encountered within the earlier approach
Giribaldi, Julien. "Synthèse de peptides bioactifs inspirés des venins". Thesis, Montpellier, 2019. http://www.theses.fr/2019MONTS124.
Testo completoNatural extracts such as animal venoms are an important source of bioactive peptides for therapeutic purposes. Peptides derived from venoms currently used in medicine include Eptifibatide, an antiplatelet drug developed from echistatin, a toxin isolated from a viper, Ziconotide, a potent analgesic identified in the venom of a cone snail and Exenatide , a glucagon-like peptide 1 receptor agonist isolated from the saliva of the Gila monster and used for the treatment of type 2 diabetes. These disulfide-rich venom peptides exhibit a constrained three-dimensional structure and increased plasma stability compared to linear peptides. Conservation of prey / predator receptors with human receptors makes venom peptides a unique source of lead compounds for the design of pharmacological tools and therapeutic compounds. It is estimated that less than 1% of the venom peptides have been pharmacologically characterized. Thus, this project aims to explore the pharmacology of novel venom-isolated peptides using solid phase peptide synthesis based on Fmoc chemistry (Fmoc-SPPS) as well as oxidative and regioselective folding strategies to produce the correctly folded and biologically active peptide for subsequent characterization. While the first part of this project is dedicated to the synthesis of linear and disulfide-poor venom peptides, the second part will be dedicated to the synthesis of disulfide-rich peptides via oxidative and regioselective folding strategies. Finally, we will use proteomic approaches integrated with transcriptomic data for the identification of new sequences from venoms. Overall, this project provides a better understanding of the pharmacology of venom peptides and identifies leads for the development of new pharmacological tools and potential drug candidates

Testo completoThe work concerns the study of bioactive SiO2, CaO, Na2O and P2O5 glasses and presents three parts. In order to connect the structure and the bioactivity, a structural study of these glasses was carried out by 29Si and 31P NMR. The study allowed to show that the progressive phosphorus addition generates an increasingly important polymerization of the silicate network and modifies slightly the phosphate entities chemical nature. The second part relates the macroporous bioactive glass elaboration with controlled porosity by transposing the « Procédé d’élaboration de substituts osseux synthétiques d’architecture poreuse parfaitement maîtrisée » to 43. 65SiO2-22. 795CaO-30. 555Na2O-3P2O5 glass. However, the densification by heat treatment generates a partial crystallization of the glass. The 23Na NMR confirms the glass-ceramic formation. The third part relates to the in vitro bioactivity evaluation as well as preliminary cytocompatibility tests of for the initial glass and the corresponding glass-ceramic. The Infra Red analysis, made on the samples plunged in simulated body fluid (SBF), showed that the glass-ceramic is more bioactive than the glass: apatite was formed after 5h15 immersion for glass-ceramic against 10h15 for glass. The cytocompatibility tests put in evidence no cytotoxicity of the glass-ceramic. This study thus allowed to correlate the glasses structure to their bioactivity. From a very bioactive glass, it was also possible to elaborate a macroporous vitreous ceramic with controlled porosity and with better in vitro bioactivity results

Testo completoSurface contamination by pathogens constitutes a major public health problem encountered in many areas such as hospitals, environment and food industry. This contamination consists in the adhesion of pathogenic or opportunistic bacteria that can attach to a biotic or abiotic surface and lead to the formation of biofilm. An effective way to fight against microbial contamination is the development of antibacterial surfaces, in order to prevent or reduce bacterial adhesion. Based on the expertise of the Laboratoire de Chimie des Substances Naturelles in the field of polysaccharides, we have undertaken the development of antibacterial materials by grafting through covalent bonds molecules presenting antibacterial properties onto lignocellulosic fibers (in this case Kraft pulp fibers). Triazoles are resistant to acid and basic hydrolysis, reductive and oxidative conditions. This moiety is also relatively resistant to metabolic degradation and is not posing particular toxicity problems. The study of the antibacterial effect has shown a bactericidal activity of the triclosan-Kraft pulp sheet against three strains frequently found in hospitals: Pseudomonas aeruginosa, Bacillus cereus and Escherichia coli. In the case of grafting photosensitizers, only the neutral porphyrin-Kraft pulp sheet material displayed a strong photobactericidal activity after irradiation

Testo completoThe process of nitrogen fixation by leguminous plants is initiated by the exchange of signal compounds: flavonoids secreted by the plant and nodulation factors (Nod factors) secreted by the bacterium. Nod factors consist in a short chitin oligosaccharidic backbone (typically tetra or pentameric) that is N-acylated at the non-reducing end by a fatty acid. Ln order to understand the role of the structural elements of the bacterial molecule (the nodulation factor) that are involved in the nodulation induction, we have prepared analogs able to trigger the organogenesis in the plant. The focus is on the symbiotic relationship between alfalfa or vetch and their specific rhizobia. The tetrameric backbone was produced by the appropriate E. Coli recombinant cells. The first type of analogs are lipo-chitooligosaccharides in which the fatty-acid is fixed on the sugar via an amine. The sulfated compounds were tested on alfalfa and proved to be still active in nodulation induction, suggesting that there is no cleavage of the fatty-acid during the recognition process. However a decrease of activity seems to prove the influence of the amide group in the recognition process. In a second time, we considered the synthesis of various analogs with modified lipid chains by a method using multi-component reactions such as Passerini and Ugi reactions. Preliminary experiments with glucosamine derivatives are very promising and extrapolation to the tetrameric compounds are in progress
