Use of seconeolitsine and N-metyl-seconeolitsine for fabrication of antimicrobial drugs. The invention refers to two phenanthrene alkaloids: seconeolitsine and N-methyl-seconeolitsine for the manufacture of drugs, preferably for the treatment of diseases caused by the Gram-positive bacteria Streptococcus pneumoniae.

Evaluation of potential anti-inflammatory drugs The team has developed new technologies, human and murine experimental models that mimic the human diseases to assess :  The molecular mechanisms and the signalling pathways involved in the activation of macrophages by drugs or diet conditions  The anti-inflammatory or anti-infectious potentials of drugs developed by the Biopharmaceutical, Cosmetic, and Food & Beverage industries Identification of new biomarkers of inflammatory, infectious diseases and tissue repair :  bioactive lipids (prostaglandines, lipoxines, resolvines)  Cytokines and chemokines Phenotypics and functional markers of macrophages In vitro and in vivo evaluation of anti- infectious, anti-inflammatory and wound healing effectiveness of drugs Ver la continuación
Phosphorus-based dendrimers for human immuno-modulation Dendrimers are a class of highly branched “tree-like” polymers. Due to their sequential process of synthesis, they are characterized by perfectly defined structure and molecular weight. As their multivalency enables polyvalent interactions with cellular and/or molecular targets, they received tremendous attention along the two past decades regarding their uses in biology: drug delivery, biological imaging and tissue engineering. They are now part in their own right of the nanobiology and nanomedicine landscape. Among dendrimers, phosphorus-containing dendrimers capped with phosphonate end groups display unprecedented immunological properties towards cells of the human immune system. In particular, we have reported that an azabisphosphonate-capped dendrimer activates anti-inflammatory and immunosuppressive responses of the human immune system. These properties have been confirmed in vivo in a mouse model of Rheumatoid Arthritis. Ver la continuación
Biaryl and heteroaryl scaffolds for fragment based drug design A structurally complex and diverse collection of small molecules can be used to explore cellular and organismic pathways in a processes analogous to genetics. In planning diversity oriented syntheses of compounds, branching reactions pathways are important because they increase the structural diversity of products by altering the skeletal array of connecting atoms. In that respect chemists continue to develop efficient and sustainable methods for the construction of much different kind of organic architectures. Among such architectures of interest our group is currently paying much attention to bioactive types of natural products-like architectures that are biaryl and aryl-heteroatomaryl containing systems. The biary moiety is an ubiquitous motif to a variety of biologically active compounds (some structures: steganone, steganacin, gallotannins, ellagitannins) with significant activities against different tumor cells. On the other hand aryl-heteroatom aryl systems are a molecular scaffold present in many natural compounds possessing antitumoral activities. By capitalizing on our knowledge in aromatic (phenolic, cinnamic, polyphenolic) chemistry, we use small highly substituted phenolic scaffolds (ex; vanilline) in order to create the necessary connections and generate libraries that can be used in the synthesis of natural products and analogues biologically active. The two main biological activities searched are: i) antioxidant derivatives with cytoprotective effects; ii) antitumoral compounds. Ver la continuación
ICEO platform : an high-throughput screening facility for Enzyme discovery The high-throughput screening facility ICEO (Ingénierie et Criblage d'Enzymes Originales) is dedicated to the screening of original enzymes, isolated from large libraries generated using techniques such as directed evolution or coming from genomic or metagenomic samples . Objectives are numerous and go from discovering new catalysts, to redesigning enzyme specificity as well as modifying catalytic properties of a potentially interesting enzyme (stability, efficiency, affinity,…) so that it can fit conditions of use different from the natural ones. Techniques focus on generating large variant libraries (104 à 1010 clones) which will be subsequently screened to isolate interesting variants for the desired property. These hits can then be re-used as templates for additional rounds of mutations, recombinations and screening so as to finally obtain an optimal clone, resulting from the cumulative effects of multiple mutations, which individual contributions are most often very difficult to predict rationally. The success of this approach depends on reliable robotic techniques allowing treating a very high number of clones with high-throughput. Internet site: http://iceo.genotoul.fr/ Ver la continuación

Software support system for helping dermatologists in the diagnosis of the melanoma --------------------------- A Research Group has developed a software support system for helping dermatologists in the diagnosis of the melanoma (a type of skin cancer). This diagnosis can use images obtained with dermatoscopic techniques and also photographs taken by the patients themselves. This system can be used as an automated way to decide the urgency to refer a patient to the dermatologist. This software is fully developed and available for demonstration. The group is open to other kind of collaboration. Ver la continuación
New process to obtain polysubstituted pyrrolidines as inhibitors of the hepatitis C virus A research team has developed a new process to obtain polysubstituted pyrrolidines as inhibitors of the hepatitis C virus. This process allows the preparation of enantioenriched polysubstituted proline derivatives after a three-step sequence. High purity, high yields and high enantiomeric ratios are achieved. The process is patented and pharmaceutical laboratories or companies are sought for license agreements or technical cooperations. Ver la continuación
Gastro-intestinal Dynamic Simulator (GDS) A research centre has developed an artif icial in vitro digestive system. This model simulates the ow n conditions of in vivo human gastrointestinal tract allowing a good understanding of the food digestion matrix and its nutrient release during gastrointestinal passage. The centre seeks partners for a technical cooperation to assess the functionalities from functional food and ingredients. Ver la continuación
Minigenome to cure HCV (Technology Offer) This invention concerns a suicide vector in the form of chimeric genomic RNA (negative strand). The negative single-strand RNA molecule is non coding. So, the sole replication complex of the virus can manage to transform it into a positive strand. The latter can then be traduced into a pathogenic compound which can destroy the contaminating virus. The infected hepatocyte returns by the way to a healthy state. Ver la continuación
New compounds with anti-herpes activity (Technology Offer) This invention concerns new family of C3-arylated-3-deazauridine with potent anti-HSV activities and negligible cytotoxicity against various cell lines. In the pool of the already tested compounds, two molecules showed enhanced activities (close to the one of the reference acyclovir). Ver la continuación
Calcemia and Response to Anticancer Drugs (Technology Offer) This invention is based on the original discovery that intracellular calcium ([Ca2+]i) negatively regulates the apoptotic signalling activated by Death Receptor engagement (Fas and DR4/DR5) (submitted to EMBO J). A decrease in [Ca2+]i results in a potentiation of the apoptotic effects of FasL, Rituximab and Trail killer, whereas an increase inhibits them. Ver la continuación
Device for stimulating living tissues by micro electrodes (Technology Offer) Here, we propose a new electrode configuration that improves the focality of electrical stimulation without the need to consider multipolar electrodes. In this configuration, we introduce a ground surface surrounding all the electrodes of the array. Stimulations are delivered between each electrode of the array and the ground surface. Using this configuration, stimulation is all the more focal that the surface conductance of the ground surface is high. Ver la continuación
Bio-microelectronic insulin demand sensor (Technology Offer) To precisely measure the demand in insulin and not only glycemia, we have for the first time used recordings on microelectrode arrays of electrical signals, the frequency of action potentials. These signals provide the first integrative read-out at the cellular level of all nutrients, sugars and hormones. We are able to detect online the electrical activity testifying for the insulin need.
