Texto completo da fonteFlavonoids are plant-produced polyhydroxylated compounds, well-known for their beneficial health effects. In order to obtain more stable and soluble derivatives for incorporation in hydrophobic formulations without damaging the biological activities of the native molecules, a solution consists to perform a regioselective acylation of these molecules. This can be accomplished by using lipase biocatalysts, in organic media. Several experimental studies dealing with such processes are available, but none of them give any explanation, at the molecular level, for the regioselectivity of such reactions. This study aimed to apply different molecular modelling tools in order to better understand, at the molecular level, the selectivity properties of the acetylation of three flavonoids (quercetin and its glycosylated derivatives isoquercitrin and rutin), by using the lipases CALB and PCL. Firstly, docking simulations were applied, in order to obtain the most probable positions and orientations of the flavonoids in the cavities of acetylated lipases. Then, molecular dynamics simulations were performed, aiming to study the structural stability of the complexes upon a period of time and specially the stability of the enzyme-substrates interactions. Finally, quantum chemical simulations (DFT) were applied to evaluate the chemical reactivity of the flavonoids as docked in the complexes. The trends observed during the simulations were well correlated with previous experimental results on the acetylation reaction of these flavonoids. Overall, the results showed that the selectivity in such reactions depends upon the substrates (flavonoid and acetate) orientations in the enzyme catalytic cavity, the intermolecular interactions that stabilize these substrates and the intrinsic chemical reactivity of the flavonoids OH groups reaching the catalytic residues

Texto completo da fonteThe aim of this work is the elaboration of rutin and esculin oligomerization process by the laccase from Trametes versicolor. A parallel synthesis process and on-line analysis of reaction media by SEC-UV and MALDI-TOF have been elaborated. The MALDI-TOF analysis has revealed the formation of simple bridges between rutin and esculin units, up to degree of oligomerization of 6 and 9 respectively. An ether bond has been observed by FTIR spectrometry for the rutin oligomers. Finally, the NMR analysis has revealed the formation of C-C and C-O bridges both on phenolic and the sugar parts of the flavonoids. At low pH and temperature, the elongation of the chain is favored, whereas increasing the dielectric constant of the solvent or the temperature favors the production of rutin oligomers. The limitation of oligomers mass is explained by the inhibition of the enzyme, probably due to the highest chelation properties of oligomers. In the case of oligorutin, a decrease of antiradical activity and an increase of xanthine oxidase inhibitory activity have been observed when the oligomers molecular mass increases. In the case of esculin oligomers, these two activities increase with the increase of the oligomers mass. For these two types of oligomers, the water solubility is considerably increased. For the oligorutins, this augmentation has been correlated to a dense network of H-bonds, which has been demonstrated by molecular modeling. Globally, the molecular modeling approach in vacuum and in solvent has allowed to establish structure-activity relationship

Texto completo da fonteThis thesis focuses on the development of polyoxylglycérides-based lipid nanoparticles to protect labile APIs, quercetin (a fragile antioxidant flavonoid) in this case. Different nanoparticulate systems were prepared by high pressure homogenization with particle size between 100 to 200 nm. These nanodispersions are very stable over several years at room temperature. Encapsulation of quercetin in compartmented lipid nanoparticles and preparation of nanocrystals have increased significantly its content in the dispersion and effectively improve its physical and chemical stability

Texto completo da fonteFlavonoids are natural substances known for their anti-inflammatory, anti-cancerous and anti-virals properties in humans. In plants, they are one of the molecules responsible for fighting pathogens. The flavonoid biosynthesis pathway as been greatly studied in plants, especially in that of the grapevine: Vitis vinifera. However, detailed studies of the exact function of the enzymes involved in the last steps of the biosynthesis of anthocyanins and proanthocyanidins remains largely lacking.The study that we propose is to synthesize molecular probes designed to specifically interact with enzymes involved in the last stages of flavonoids biosynthesis. Our probes, based on the emerging chemical proteomic technology, activity- and affinity based protein profiling (ABPP), were validated with a model enzyme: leucoanthocyanidin dioxygenase (LDOX). After which, they were used with complex protein mixtures from Vitis vinifera
