Повний текст джерелаAntibiotics resistance or increase of difficulty to treat for current diseases with commercially available compounds has obligated researchers to find new sources of active molecules. Lichens produce various biologically active compounds due to the great diversity of their ecosystem. Thus, they represent a promising source of bioactive compounds. Chemical profiling of Nephroma laevigatum was performed. LC-MS/MS analysis with molecular network approach allowed understanding chemical diversity of this lichen and four different compounds were isolated and identified by NMR and tested for their antiproliferative activity. However, lichen resources are limited, which limits their use. In addition, lichen thalli are an ecological niche for other microorganisms and a wide reservoir for access to bioactive molecules. Cultivation of endolichenic fungi was undertaken. Thus, 46 strains were isolated and identified by DNA barcoding (primers ITS4 and ITS5). The isolated fungi belong to genus Nemania, Daldinia, Peziza and Coniochaeta. Biological investigation was carried out on six selected strains belonging to two species (Nemania aenea var. aureolatum and N. serpens). So, two strains distinguished by their antiproliferative and anti-biofilm activities. Further chemical and biological studies of these strains (Gir_20 N. aenea var. aureolatum and Cor_08 N. serpens) were subsequently performed and eight different compounds were isolated and identified by 1D and 2D NMR. Study of effect of the extracts on the human cancer lines HT-29, HCT116, PC-3 and DU145 made it possible to highlight morphological changes at the cellular level. Analyses of the expression of pro- and anti-apoptotic protein markers as well as DNA fragmentation demonstrate the induction of apoptosis. LC-MS/MS chemical profiling of these strains was performed and compared with molecular network approach, to visualize chemical diversity between the two species of endolichenic fungi

Повний текст джерела1/ Evaluation of canthin-6-one anti-proliferative properties Canthin-6-one is an alkaloid molecule produced by tropical plants used in traditional medicine for its antipyretic and antiparasitic properties. Evidence-based medicine requires better knowledge of canthin-6-one's anti-proliferative effects and mode of action. In the presence of canthin-6-one, we demonstrated a complete growth inhibition of human cancer cells due to the accumulation of cells in the G2/M phases of the cell cycle. Cell cycle pathways being evolutionarily conserved in eukaryotes, we used the yeast Saccharomyces cerevisiae as a model system to further analyze the mode of action of canthin-6-one. A yeast genomic library was screened for suppressors of canthin-6-one toxicity and two resistance genes were identified. One encodes a transporter, probably involved in canthin-6-one efflux. The other one encodes an enzyme involved in DNA quality control.2/ Role of calcium signaling in photoreceptor differentiationThe design of new treatments for retinal degenerations should benefit from better knowledge of photoreceptor differentiation. During retinal differentiation in chicken embryos there is a long time lag between commitment to the photoreceptor fate and transcriptional activation of rhodopsin gene, suggesting committed precursors are in a standby state waiting for a signal to activate opsin gene expression. We demonstrate by a pharmacological approach in vitro that rhodopsin gene activation depends on a signaling pathway involving hyperpolarisation-activated channels (HCN), T- or R-type calcium channels and calmodulin-dependent protein kinase. The expression profile of HCN1 in the embryonic retina suggests it may be a limiting factor for rhodopsin gene activation

Повний текст джерелаGlycoligands are ligands centered on a sugar platform and functionnalized by Lewis bases. They are constrained and rigid chelating molecules implying the conformational properties of the sugar into the coordination sphere. During this PhD, several series of glycoligands centered on furanoses were synthesized with a systematic modification of the configuration of the carbon C3 and of the chelating claws. Glycoligands and their complexation properties were analysed by different physico-chemical techniques such as the UV-visible, EPR, IR, fluorescence, circular dichroïsm, RX diffraction spectroscopies and also such as cyclic voltametry, confocal microscopy and microcalorimetry. Studies on cells were also performed to test their potential antiproliferative activity on tumorous cell lines. Tuning of glycoligands with various chelating claws, revealed that they are ligands enough constrained to control the oxidoreduction potential of the couple Cu (II/I), the predetermination of chirality of dimeric Cu (II) glycocomplexes and the metal selectivity. Furthermore, biological tests highlight the possible vectorisation of Cu (II) glycocomplexes by the apo-protein NCS to get an increased activity of a factor two to three. Due to the exceptional fluorescence of one of the glycoligand, its permeability towards membranes of giant unilamellar vesicles and biodistribution could be studied. Its antiproliferative activity was related to its localisation in some organelles but not in the nucleus of U937 cell line

Повний текст джерелаNowadays, cancer is the second leading cause of death in the developed countries after cardiovascular disease. Basing on these statistics, we are interested in the design and synthesis of new molecules as new potent anticancer agents. From a chemical point of view, we carried out the modifications of the carboxylic acid function and the aromatic part of the ethacrynic acid (EA). The different structural modifications were made to design a diverse library of original EA analogs. In the first part of this manuscript, we prepared a new series of EA derivatives, carrying sulfonamide, urea or thiourea moieties via a peptide coupling reaction between the EA and aminosulfonamides, ureoamines or thioureamines, previously synthesized. The second part was reserved for the preparation of other families of EA bearing triazole moiety, using Huisgen cycloaddition reactions. Simultaneously, fluorescent EA derivatives have also been synthesized. In order to increase the reactivity of the Michael acceptor, the last part of this thesis was devoted to the modification of the aromatic ring of EA using new synthesis method. From a pharmacological aspect, all the obtained results showed that most of the synthesized EA derivatives exhibited significant antiproliferative activities with IC₅₀ values ranging from micromolar (µM) to nanomolar (nM) on a panel of cancer cell lines, with excellent selectivities (> 80%)

Повний текст джерелаGlycolipids (GL) from marine sponges give rise to a growing interest because of their immunomodulating and antitumoral properties, while those of the echinoderms remain little documented. This work describes the isolation and the characterization of two biologically active types of GL: glycosphingolipids (GSL) and ether-linked GL (mono-O-alkyl-diglycosylglycerols). A major GSL of the starfish Narcissia canariensis (Senegal), ophidiacerebroside-C, was isolated and identified. It contained a β-glucopyranoside, a 9-methyl-4,8,10-triunsaturated long-chain aminoalcohol amide-linked to a C22 α-hydroxylated acyl chain. This GSL and its two minor homologous ones displayed a cytotoxic activity over 24 h on various adherent human cancerous cell lines (multiple myeloma, colorectal adenocarcinoma and multiforme glioblastoma) with an IC50 of around 20 μM. The major GSL, Axidjiferoside-A, from the sponge Axinyssa djiferi (Senegal) contained β-galactopyranoside and 2-amino-octadec-6-en-1,3,4-triol linked to an α-hydroxytetracosanoic acyl chain. It seemed of interest, associating an antiplasmodial activity (IC50 = 0. 53 μM against a chloroquine-resistant strain of Plasmodium falciparum) with a low cytotoxicity on five cancer cell lines. The new Myrmekioside-E from Myrmekioderma dendyi (south Pacific) contained a glycerol backbone linked to xylose and N-acetylglucosamine, and an alkyl long-chain with a terminal alcohol group. A GL named Trikentroside, with a glycerol, two xyloses and an unsaturated C24 chain, from the sponge Trikentrion laeve (Senegal) was subjected to a comparative biological evaluation. Both GL inhibit proliferation of two human lung cancer cell lines
