Full textLectinas podem ser definidas como proteÃnas/glicoporteÃnas que reconhecem carboidratos de maneira especÃfica, mas nÃo participam do metabolismo dos mesmos e nÃo pertencem a nenhuma das principais classes de imunoglobulinas. As lectinas sÃo proteÃnas ubÃquas, estando presente em todos os organismos conhecidos. Em cÃlulas animais, lectinas tÃm sido encontradas no citoplasma, no nÃcleo e associadas a membranas das mais diversas organelas e nos mais variados tipos celulares. Tais lectinas animais podem ser classificadas em famÃlias distintas com base em suas caracterÃsticas fÃsico quÃmicas, funÃÃo e especialmente em sua identidade de estrutura primÃria e terciÃria. O objetivo deste trabalho foi purificar duas novas lectinas da esponja marinha Haliclona (Soestella) caerulea e caracterizar estruturalmente uma delas. EspÃcimes de H.caerulea foram coletados na praia do paracuru, CearÃ. Duas lectinas (H-1 e H-3) foram isoladas por tÃcnicas clÃssicas de quÃmica de proteÃnas. A estrutura primÃria de uma delas foi determinada por espectrometria de massas e RACE. A atividade tÃxica das lectinas foi avaliada frente à nÃuplios de Artemia e cepas das bactÃrias Escherichia coli e Staphylococus aureus. H-1 e H-3 apresentaram caracterÃsticas distinhas da lectina previamente isolada de H. caerulea. H-1 à uma proteÃna monomÃrica de aporoximadamente 40 kDa enquanto que H-3 à uma proteÃna trimÃrica com cadeias com massa aproximada de 9, 16 e 18 kDa. H-3 aglutina eritrÃcitos humanos do tipo A e B e foi inibida GalNAc e PSM, H-1 aglutina diversos grupos sanguineos e nÃo pÃde ser inibida por nenhum aÃÃcar testado. H-1 foi tÃxica a naÃplios de Artemia (LC50=6,4 μg.mL-1) e H-3 foi considerada nÃo tÃxica (LC50=414,2 μg.mL-1). H-3 à uma proteÃna azul, pois interage com um cromÃforo de 597 Da com absorÃÃo mÃxima a 620 nm. A estrutura primÃria de H-3 foi determinada e revelou-se Ãnica, nÃo sendo conhecida nenhuma lectina com estrutura similar. H-3 apresenta um glicano hÃbrido composto por Hex7NAcHex7DeoxiHex2. A cadeia α de H-3 sofre um processamento proteolÃtico complexo que ainda nÃo foi completamente elucidado. AlÃm disso, H-3 foi cristalizada, mas nÃo foi possÃvel a obtenÃÃo de um padraÃo de difraÃÃo que permita a resoluÃÃo da estrutura. Em suma, duas novas lectinas foram isoladas e fora observado pela primeira vez a interaÃÃo entre uma lectina e um cromÃforo natural. Pela primeira vez tambÃm, fora determinada a composiÃÃo glicÃdica de uma lectina de esponja.
Lectins are proteins/glycoproteins that recognize carbohydrate of a specific way, but not participate in the metabolism of the same and do not belong to any of major classes of immunoglobulins. Lectins are ubiquitous proteins, present in all known organisms. In animal cells, lectins have been found in the cytoplasm, in the nucleous and as membrane-associated proteins, in diverse organelles and cells. Animal lectins can be classified into distinct families based on their physicochemical characteristics, especially in their function and identity of primary and tertiary structure. The aim of this study was to purify, characterize structural and biologically new lectins from the marine sponge Haliclona (Soestella) caerulea. H. caerulea specimens were collected in Paracuru beach, CearÃ. Two lectins (H-1 and H-3) were isolated by classical techniques of protein chemistry. The primary structure of H-3 was determined by mass spectrometry and RACE. The toxic activity of lectins was evaluated against Artemia nauplii and Escherichia coli and Staphylococcus aureus strains. H-1 and H-3 showed distinct characteristics of the lectin previously isolated from H. caerulea. H-1 is a monomeric protein of 40 kDa whereas H-3 is a heterogeneus protein with chains of 9, 16 and 18 kDa. H-3 binds human erythrocytes of A and B type and was inhibited by GalNAc and PSM, H-1 binds different blood groups and could not be inhibited by any sugar tested. H-1 was toxic to Artemia nauplii (LC50 = 6.4 μg.mL-1) and H-3 was not considered toxic (LC50 = 414.2 μg.mL-1). H-3 is a blue protein that interacts with a chromophore of 597 Da of maximum absorbance at 620 nm. The primary structure of H-3 revealed a unique amino acid sequence no similar to any animal lectins known. H-3 has a hybrid glycan comprising by Hex7NAcHex7DeoxiHex2. The α-chain of H-3 undergoes complex proteolytic processing that not been fully elucidated. Moreover, H-3 was crystallized, but was not possible to obtain a diffraction pattern that permits solving the structure. In short, two new lectins were isolated and out first observed the interaction between a lectin and natural chromophore. Furthermore, for the first time given the composition glicidic out of a sponge lectin.

Full textSince about fifty years, several studies described sponges as astounding resources of original natural products. These discoveries aroused scientist’s curiosity in various areas (chemistry, biochemistry, molecular biology) and to understand these animal’s functioning, they share their knowledge. The proposed work in this manuscript, focus on sponges of genus Haliclona from the order Haplosclerida. Indeed, this taxonomic group reveal peculiar chemical families, including 3-AP alkaloids and polyacetylenic compounds, displaying pharmacological potential to be exploited. Besides, chemicalDépôt de thèseDonnées complémentairesdiversity encountered in this genus challenge the actual classification of Haplosclerida group already disputed by biomolecular data. The particular interest in these original compounds also concerns metabolic pathways leading to their biosynthesis. In this way, 3-AP alkaloids, which don’t have any equivalent particularly in terrestrial area, the description of their biosynthesis pathway was only considered by hypothesis. To resolve various problematics proposed by this sponges’ group, studies conducted through this PhD appeal to several methods and technics like usual natural products chemistry extraction and analytical technics, recent tool named metabolomic or feeding experiments with radiolabelled compounds

Full textOur work deals in the first part with a biomimetic synthesis of bipleiophyllin, an indolomonoterpenic alkaloid. The bipleiophyllin is the result of a complex anchorage of two identical indolic subunits on an aromatic platform. A general strategy for the biomimetic synthesis of bipleiophyllin consisting of i) the synthesis of the indolic unit pleiocarpamin and ii) the oxidation of 2,3-dihydroxybenzoic acid; was considered. Access to the complex skeleton of pleiocarpamin has been studied by different total synthesis strategies but also by hemisynthesis. Meanwhile this work, a study of the oxidation conditions of 2,3-dihydroxybenzoic acid including by electrochemistry, helped identify and characterize its oxidation potential and develop the required conditions to obtain its oxidized form. The second part is devoted to the biomimetic synthesis of a model compound, mimic of the central core of haliclonin A, an alkaloid of the family of manzamins. The synthesis of several precursors and the study of the key step consisting in a double nucleophilic addition to a 5,6-dihydropyridinium were done

Full textIn a search for new antiplasmodial compounds, one Haliclona and four Aplysina ianthelliformis sponges were chemically investigated to furnish 21 compounds, seven of which are novel ones 141-147. The Haliclona sponge gave the known product, haliclonacylamine A 129 which exhibits potent in vitro activity against the chloroquine-resistant strain, Plasmodium falciparum FCB-1 with an IC50 of 98 nM and a strong selectivity index of 57 and 67 (determined as antiplasmodial activity/ cytotoxicity). In the in vivo mice model, haliclonacyclamine A 129 gave 45% parasitaemia inhibition on the fourth day following three days of treatment at 10 mg/Kg/day administered intra-peritoneally to Swiss female mice infected with P. Vinckei petteri. The A. Ianthelliformis sponges furnished 20 compounds, all but two (aureol 137 and aplysterol 138) of which are bromotyrosine derivatives. All bromotyrosine-derived compounds; 35a, 36, 130-147 exhibit mild in vitro activities against the chloroquine-resistant and sensitive strains, P. Falciparum FCB-1 and 3D7 respectively, with IC50s ranging between 0. 9 – 50. 5 µM. All bromotyrosine compounds lack selectivity except for araplysillin I 139 which has a weak selectivity index of 5. 5 and 6. 5 (measured for MCF-7 and Vero cells respectively) and an IC50 value of 4. 5 µM against P. Falciparum, FCB-1. All bromotyrosine derivatives, except for the novel compound 144, also exhibit weak Protein farnesyltransferase (PFTase) inhibitory activity; the most active, aerophobin II 135, has an IC50 of 8. 0 µM. The inactivity of compound 144 suggests the importance of the isoxazoline motif in conferring PFTase activity in bromotyrosine compounds

Full textThe work described in this manuscript concerns four sponges from the South-West Indian Ocean: Plakortis kenyensis, Theonella swinhoei, Haliclona fascigera and Fascaplysinopsis reticulata. The chemical study of the sponges including extraction, isolation and identification of secondary metabolites was undertaken using various chromatographic (MPLC, HPLC ...) and spectroscopic (UV-visible, HRMS, 1D and 2D NMR ...) techniques. Twelve secondary metabolites including six new molecules were isolated from these sponges. The new molecules are: 2,5-époxydocosan-6-en-21-ynoic acid (HF1) an unusual fatty acid isolated from the sponge Haliclona fascigera; 8-oxo-tryptamine (FR2), 6,6'-bis (debromo)-gelliusine F (FR3), 6-bromo-2'-demethyl-3'-N- methyl-1',8-dihydroaplysinopsine (FR6), 5,6-dibromo-2'-demethyl-3'-N-methyl-1',8-dihydroaplysinopsine (FR7) and 5,6-dibromo-3’-deimino-2’-demethyl-3’-oxo-1’,8-dihydroaplysinopsine (FR8), five indole alkaloids isolated from the sponge Fascaplysinopsis reticulata. The biological activities of the isolated molecules were then evaluated. Among the twelve isolated molecules, seven were active against the malaria parasite Plasmodium falciparum, three were identified as inhibitors of the quorum sensing-regulated bioluminescence in Vibrio harveyi and five, showing marine bacterial adhesion and/or growth inhibition, exhibited potential anti- microfouling activity
