Повний текст джерелаBacteria which are prolific sources of antibiotics and important suppliers to the pharmaceutical agents can produce a wide variety of metabolites. Thus finding metabolites from the bacterial lineages represented new interests for chemists. Among that, lichens are admitted as a rich source of new bacterial lineages and novel bacterial compounds. Therefore, microorganism communities associated with lichens became significant subjects as great potential for the production of active natural compounds. In this thesis, we focus our work on the isolation of bacterial lineages from the lichen Rhizocarpon geographicum, one of the most popular crustose lichens dwelling on the rock. Among the strains isolated, Paenibacillus odorifer was selected for further work to produce active compounds. After the culture optimization steps, the study of extracts from the P. odorifer cultures either in the bioreactor or in Erlenmeyer flask led to the production of metabolites: an antioxidant polysaccharide, two cytotoxic tert-butylphenol derivatives which came from the bioaccumulation and biotransformation of precursors, a novel and cytotoxic alkaloid compound, two diol compounds, two furfural derivatives and some other known compounds. Putative biosynthetic pathways have been proposed for some compounds. The diversity of metabolites isolated from P. odorifer highlighted that this species possessed a great potential of the production active compounds and were a new case of tert-butyl phenol utilizing bacterium

Повний текст джерелаThe oral bacteria do not only infect the mouth and reside there, but also travel via the blood and reach distant body organs. If left untreated, the dental biofilm that can cause destructive inflammation in the oral cavity may result in serious systemic medical complications. In dental biofilm, Streptococcus gordonii, a primary oral colonizer, constitutes the platform on which late pathogenic colonizers like Porphyromonas gingivalis, the causative agent of periodontal diseases, will bind. The aim of the first study was to determine the antibacterial activity of eleven natural lichen compounds belonging to different chemical families to uncover new antibiotics which can fight against the oral bacteria. Three compounds were shown to have promising antibacterial activities where psoromic acid had the lowest MICs of 11.72 and 5.86 µg/mL against S. gordonii and P. gingivalis, respectively. Novel butyrolactone analogues were then designed and synthesized based on the known lichen antibacterial compounds, lichesterinic acids (B-10 and B-11), by substituting different functional groups on the butyrolactone ring trying to enhance its activity on S. gordonii and P. gingivalis.. Among the derivatives, B-12 and B-13 had the lowest MIC of 9.38 µg/mL where they have shown to be stronger bactericidals, by 2-3 times, than the reference antibiotic, doxycycline. B-12 and B-13 were also the most efficient on P. gingivalis exhibiting MIC of 0.037 and 0.293 µg/mL and MBC of 1.17 and 0.586 µg/mL, respectively. These 2 compounds were then checked for their cytotoxicity against human gingival epithelial cells and macrophages by MTT and LDH assays which confirmed their safety against the tested cell lines. A preliminary study of the structure-activity relationships unveiled the important dual role contributed by two substituents, alkyl chain at C4 and carboxyl group at C5 positions, in their mechanism of action. This was followed by the investigation of B-12 and B-13 for their antibiofilm activity against both oral strains using crystal violet assay and confocal microscopy. Both derivatives displayed a lowest concentration with maximal biofilm inhibition, LCMI, of 9.38 µg/mL against S. gordonii and 1.17 µg/mL against P. gingivalis. However, when sub-inhibitory concentrations of B-12 and B-13 were used, we demonstrated that the two investigated strains were able to form biofilms in vitro. Indeed, this antibiofilm activity decreased as indicated by the expression of the genes implicated in adhesion and biofilm formation. To better understand the mechanism of action of butyrolactones, we have investigated B-13 bacterial localization by synthesizing a fluorescently labeled B-13 with NBD (4-nitro-benzo[1,2,5]oxadiazole) conserving its antibacterial activity. By confocal microscope, we showed that this compound binds to S. gordonii cell surface and this was also demonstrated by HPLC analysis. By adhering to cell surface, B-13 induced cell wall disruption leading to the release of bacterial constituents and consequently, the death of S. gordonii, a Gram-positive bacterium. The expression of two genes, murA and alr, implicated in cell wall synthesis, was modified in the presence of this butyrolactone. Gram-negative bacteria such as P. gingivalis showed also cracked and ruptured cells in the presence of B-13, suggesting that this butyrolactone acts on Gram-positive and Gram-negative strains, but with greater efficacy against the Gram-negatives. Besides, we also demonstrated that the analogue of B-13, B-12, has also induced disruption of P. gingivalis and S. gordonii. All these studies demonstrated that butyrolactones derived from a lichen metabolite can be proposed as potent antibacterial agents against oral pathogens causing serious medical complications

Повний текст джерелаThe discovery of novel secondary metabolites has declined significantly in recent years whereas there is a rise in the number of multi-drug resistant pathogens and other types of diseases. The decline in natural product discovery was due to high rediscovery of already known compounds and the costs in developing natural products. As a result pharmaceutical companies lost interest in investing in natural product discovery. However, there is a renewed interest in marine sponge associated microorganisms as a rich and untapped source of secondary metabolites. The objective of this study was to design a matrix to investigate the extent to which the One Strain-Many Compounds (OSMAC) approach applies to a collection of marine sponge isolates harvested from two South African marine sponge samples. Terminal restriction fragment length polymorphisms (T-RFLP) analysis was used to investigate and ascertain the two marine sponges which hosted the highest microbial diversities to be used for further culture-dependent studies. The culture-dependent studies, using 33 media which included liquid enrichment, heat treatments and antibiotic treatments, resulted in 400 sponge isolates from the two marine sponges Isodictya compressa and Higginsia bidentifera. Using antibacterial overlay assays, 31 dereplicated isolates showed antibacterial activity. Bioactivities were also exhibited against E. coli 1699 which is genetically engineered for resistance against 52 antibiotics which implies that some of the bioactive compounds could be novel. The 16S rRNA gene sequences revealed that the microbial phyla isolated from the marine sponges belonged to Actinobacteria, Firmicutes and Proteobacteria (Alphaproteobacteria and Gammaproteobacteria).Thirty isolates were selected for an OSMAC-based matrix study, 17 of which showed noantibacterial activities in preliminary screening. The application of the OSMAC approach using co-culture and 36 culture conditions resulted in 6 isolates showing antibacterial activities, three of which did not show activities in preliminary screening. One of these, a Bacillus pumilus isolated from I. compressa displayed antibacterial activity against 5 indicator strains whereas in preliminary screening it had not shown activity. The results show that marine sponges can host novel microbial species which may produce novel bioactive compounds. The results also confirm that traditional methods employing a single culture condition restricts the expression of some biosynthetic pathways of microorganisms and as a result many metabolites have yet to be identified.
