Full textKinases are an important family among human proteins that include 518 identified members so far. They play key roles in the living functions such as proliferation, survival, migration of cells and apoptosis that make them of tremendous interest as potential and highly studied therapeutical targets. In particular, many cancers are associated with kinase dysfunction, overactivation, overexpression or repression. They are also involved in auto-immune and inflammatory diseases. Kinase inhibitors development is a challenge of modern medicinal chemistry, as the high conservation of their activity domain makes it difficult to design of specific inhibitors as well as mandatory given the broad spectrum of regulated phenomenon through their pathways. We hereby propose to design a specific inhibitor of a therapeutically validated kinase in the field of oncology. That kinase is however and despite the need not specifically targeted by any compound in the market so far. We previously obtained a small and highly derivatizable hit that we decided to optimize step by step in order to obtain new chemical entities of high potential toward that specific kinase

Full textAlzheimer’s disease (AD), the most frequent form of dementia, is characterized by aggregation and intraneuronal accumulation of abnormally modified microtubule-associated Tau proteins (Tau pathology) along with extra-neuronal amyloid deposits (Amyloid pathology). There is currently no cure for AD and available treatments offer only modest and short-term symptomatic benefits. Current drugs are no longer reimbursed by Social Security.A family of molecules (named MSBD) developed in our lab was shown to act on both amyloid and Tau pathologies in vitro and in vivo. The lead of this series, AZP2006 is currently ending phase 1 clinical trials. However, its biological target remains unknown. In this first part of this work, a program based on a "ligand based" approach associated with de novo design was finalized to discover potential anti-Alzheimer agents. Several pharmacomodulations revealed structure-activity relationship and allowed to discover a series of indirect β-secretase inhibitors that promote non-amyloidogenic processing of the Amyloid Precursor Protein. In second time, the design and synthesis of photoaffinity labelling probes (PAL) was applied toward the elucidation of the mode of action of the AZP2006. Thirdly, a molecular modelling study was undertaken for the initiation of a new medicinal chemistry project based on a "ligand based" approach. Virtual screening of a library was performed to allowed the discovery of potential activators of the SIRT1 protein as anti-Alzheimer agents

Full textInflammation is a phenomenon affecting millions of people throughout the world. There is a broad range of inflammatory mediators implied in different biological functions including the cyclooxygenase-2. Although many selective inhibitors selective of COX-2 have been developed and marketed, they have displayed diverse side effects leading, in some cases, to their with drawal from the market. Nowadays, in silico methods are more and more used in the drug discovery process. In this project, we have used pharmacophoric models and docking methods to guide and prioritize the synthesis of molecules, presenting different and original structures, with enhanced affinity for the biological target. Thus, predictions realized with the TOMOCOMD-CARDD software together with biological tests enable to identify the cyclocoumarol as a potential anti-inflammatory molecule. As part of these works, the synthesis of and the study of cyclocoumarol analogues as selective inhibitors of COX-2 have been realized. Pharmacomodulation of cyclocoumarol and development of synthesis strategies led to a serie of cyclocoumarol analogues. Several bioinformatics tools have been used: selective COX-2 pharmacophores were elucidated using LigandScout and docking studies (Surflex) were conducted to understand the binding mode of different compounds. Finally, SeeSAR enabled to predict the affinity of the molecules the most susceptible to inhibit selectively COX-2. Biological tests confirmed their inhibitory activity against COX-2 and showed no significant inhibition for COX-1. Among the synthesized molecules, the 4-OMe cyclocoumarol has demonstrated an activity and a selectivity very interesting, similar to NS-398, a known selective COX-2 inhibitor.Based on the biological results obtained, a pharmacomodulation study of cyclocoumarol derivatives has been realized using in silico tools in order to predict the affinity of new compounds and to discover new selective inhibitors of COX-2.Keywords : cyclocoumarol, benzalacetones, warfarines, pharmacophores, docking, virtual screening, COX-2, repositioning

Full textThis work focuses on the research and development of new therapeutic molecules through optimized radical cyclizations mediated by manganese(III) acetate. Two problematics directed our research. First, we developed analogous prodrugs of pafuramidine, an antileishmanial molecule. Thus, a 1rst series of amidoximes was obtained from β-ketosulfones by a multi-step synthesis involving i) radical oxidative cyclizations mediated by Mn(OAc)3 and ii) pallado-catalyzed Buchwald-Hartwig and Heck coupling reactions. The 1rst series being biologically evaluated in vitro, both on Leishmania donovani and human cells, a 2nd series and particularly monoamidoximes was prepared and revealed a molecule presenting a selectivity index 40 times higher than the one of pentamidine, used as reference drug compound. We also developed a one-pot double Buchwald-Hartwig coupling reaction in the aim to obtain dissymmetric dicoupled products, potential precursors of future diamidoximes. In a second time, we focused on the synthesis of spirocyclic compounds which could constitute an original pharmacophore. Therefore, we performed a synthesis allowing access to a wide variety of scaffolds such as spirocyclic tetralins, spirolactones, spirobenzophenanthridin-6(5H)-ones. This work allowed the synthesis of thiobarbiturates, analogous of anesthetic or anticonvulsive compounds

Full textLeishmaniasis is a set of disease caused by a parasite of the genus Leishmania. The increased resistance to currently available treatments led to the need to develop new antileishmanial compounds. GDP-MP, an enzyme essential for the virulence of the parasite was chosen as a therapeutic target. In the first part of this work, GDP-MP models L. donovani and H. sapiens were constructed by molecular modeling using the method of sequence homology and molecular dynamics relaxation. The evaluation of inhibitors by molecular docking has led to the identification of many potential inhibitors of GDP-MP. Among these molecules identified, some are GDP-Mannose analogs having different substitution patterns for the pyrophosphate bridge and for guanosine. Another class of compounds is the analogues of GDP wearing bisphosphorus moiety. A methodological study for the synthesis of guanosine conjugated 1,4-triazoles analogs by CuAAC was conducted and showed the effectiveness of the use of copper nanoparticles (I), formed in situ by reduction of copper sulfate in aqueous solution of hydrazine hydrate, for the synthesis of these compounds. This method in combination with the H-phosphonate chemistry, has allowed access to a library of derivatives of GDP-Mannose. In this way, guanosine analogs, and variously substituted quinolines were synthesized. The obtained compounds were evaluated on the recombinant GDP-MP as well as parasite cultures. Some bisphosphonate compounds have both a good inhibition of the GDP-MP and good antiparasitic activity. Future experiments of protein crystallography will elucidate the mode of binding of these compounds and will determine future pharmacomodulations on the identified inhibitors

Full textThis manuscript describes the design, synthesis and biological evaluation of oroidin analogs. Oroidin is a monomer of benzosceptrin C, belonging to the pyrrole-2-aminoimidazole family, isolated from marine sponges. The simplification and structural diversification approaches led us to the identification of a non-natural hit displaying selective inhibitory activity against the kinase Aurora B. This kinase plays a key role in cell division and its inhibition leads to severe mitotic abnormalities. Aurora B is found to be up-regulated in many human cancers, indicating that this kinase is a cancer-relevant target. The objective of the study at the interface between chemistry and biology is to optimize the discovered hit into a lead. The hit scaffold is divided in three parts: the 4,5-dibromopyrrole, the imidazo[1,2-a]pyrimidine and the alkyne moieties. After the first introductive chapter, chapters II to IV are dedicated to the pharmacomodulations of each part. We finally managed to synthesize eighty-two analogs for in vitro evaluations toward Aurora B and a panel of kinases involved in diverse human pathologies. Several compounds were found to be very active with IC50 down to 34 nM, displaying a 150-fold higher activity than the initial hit. The last chapter discusses the mode of action of the most active inhibitors from the hit expansion. The enzymatic kinetic assays revealed an uncommon mode of action with allosteric inhibitors (type IV) of Aurora B. Immunostaining experiments highlighted the typical effects of Aurora B inhibition in treated cells as well as its quantification. At last, molecular docking study with the best inhibitor showed the most probable allosteric binding pocket of Aurora B, providing crucial support in hit-to-lead optimization. In conclusion and perspectives, the efforts to be pursued in order to improve physicochemical and pharmacokinetic properties in the lead-to-candidate process are pointed

Full textIn the field of pharmaceutical compound crystallization, a better knowledge of the nucleation process is essential to control the nucleation rate, the growth and therefore the size and the quality of crystals. This work focuses on difficulty to crystallize some drugs. It becomes clear that, an important stage is the phase diagram investigation of the considered substance. In our case, polymorphism and liquid-liquid (L-L) phase separation or demixing were observed. On the one hand, the temperature controlled by Peltier effect has allowed us to characterize and to keep the stable polymorph in suspension using optical microscopy. On the other hand, the L-L phase separation has been characterized in stagnant medium by light scattering, optical microscopy and each coexistence liquid phases were titrated by HPLC and Karl Fischer. The L-L phase separation was observed in the metastable zone of polymorphs and consequently hindered the crystallization. Finally, the demixing is )aracterized in stirred solution and its effect on the drug crystallization by seeding was studied by turbidity and in-line focused beam reflectance measurements (FBRM)

Full textLe criblage à haut débit de 10000 produits issus de chimiothèques combinatoires diverses sur le récepteur aux benzodiazépines, a permis de mettre en évidence une nouvelle série de ligands de type tri-aromatique. Grâce aux résultats du criblage primaire, nous avons conçu, synthétisé et testé 6400 analogues. De nombreux analogues ont montré une activité submicromolaire. Nous nous sommes ensuite intéressés à l'optimisation de deux composés micromolaires sur le récepteur aux opiaces de type mu, obtenus précédemment par criblage systématique de chimiothèques combinatoires. Nous avons conçu des analogues présentant une topologie conservée ou un pharmacophore conservé par rapport à la référence. Les analogues synthétisés au cours de cette optimisation ont été soumis à une caractérisation biologique étendue permettant d'évaluer puissance et spécificité. Des composes nanomolaires sur la cible et très spécifiques des sous-types opiaces ont ainsi été mis en évidence. Ayant à notre disposition de grande séries de composés et d'activités biologiques, nous nous sommes attachés à montrer les liens entre les structures chimiques et la spécificité des composés dans la série étudiée

Full textPour les industriels du secteur de la chimie pharmaceutique, qui comptent parmi les exploitants des systèmes à risques, le développement d'une culture de sécurité dans les sites de production est une nécessité. Des évolutions techniques et la mise en place de systèmes spécifiques de gestion leur ont en effet permis d'obtenir des résultats largement meilleurs que la moyenne des entreprises mais qui semblent plafonner dans le temps. Développer une culture de sécurité dans les usines nécessite cependant de changer de regard sur la maîtrise des risques. Cela nécessite en effet de prendre en compte toutes les dimensions de l'organisation en replaçant l'être humain au centre des préoccupations.
Ce travail de recherche se situe dans le domaine de la recherche en gestion, dans le courant de l'analyse de l'activité collective. Il vise à répondre à plusieurs objectifs. En premier lieu, décrypter les logiques d'action sous-jacentes à la notion de culture de sécurité afin de déterminer le projet managérial qu'elle implique. Ensuite, identifier les processus de gestion mis en œuvre pour concrétiser ces logiques d'action afin d'observer comment le projet managérial culture de sécurité se met en œuvre. Enfin, analyser certaines activités liées à ces processus, notamment la formation du personnel et le retour d'expérience, afin de faire émerger des leviers d'action permettant de développer la culture de sécurité.
Le terrain d'intervention est constitué des usines de production d'un grand industriel français de la pharmacie.
L'approche proposée a été mise en œuvre dans différentes usines de production de composés chimiques et à l'échelle de la branche chimie du partenaire industrielle. Elle a permis d'identifier les leviers de progrès dans les activités de maîtrise des risques qui contribuent à développer et à renforcer une culture de sécurité devant permettre d'améliorer les résultats de sécurité des sites chimiques étudiés.
La démarche de recherche mise en œuvre peut être adaptée à d'autres secteurs industriels désireux de développer ou renforcer une culture de sécurité et prêts à mettre à plat leurs pratiques de maîtrise des risques industriels.

Full textThe antiviral chemotherapy has strongly grown in the last decades and new drugs are currently available for the treatment of viral diseases. Nevertheless, problems such as toxicity of treatments and emergence of resistant viral strains still occur. In the case of Human Immunoodeficiency Virus and herpes virus, including human cytomegalovirus (HCMV), infections, problems such as chronic treatment add. In arder to limit these drawbacks, we studied vectors able to carry antiviral molecules and thus to improve their pharmacological properties. The vectors used were cyclodextrins (Cds) which are neutral saccharides forming a cage in which a wide range of drugs can be encapsulated and hence have their absorption and therapeutic efficiency improved. We studied through Nuclear Magnetic Resonance and spectrometry the ability of three native Cds, [alpha]-,[beta]- and [gamma]-. Cds, to form inclusion complexes with ganciclovir (GCV), an anti-HCMV agent. We tested the influence of these Cds on the in vitro antiviral activity of GCV against various HCMV strains. Only [beta]-Cd was able to form a complex with GCV and we demonstrated that it could improve the in vitro antiviral activity, of GCV. In order to test the influence of complexation of anti-HCMV molecules on their in vivo antiviral activity, we developed a murine model of cytomegalovirus infection. We then determined the experimental conditions of the infection and evaluatecl the infectiosity of the virus in mouse organs according ta time. In this in vivo model, we carried out preliminary studies on the antiviral activity of complexed GCV with [beta]-Cd, which revealed an improvement of its efficiency

Full textThis work describes the development of biocompatible functionalisation methods of wide interest in the field of biomedical applications. A new water-compatible coupling method between nitrones and strained-cycloalkynes is here developed, by analogy with the [3+2] cycloaddition between azides and strained-cycloalkynes described in the literature. The efficiency of the coupling is evaluated by fluorescence imaging. Two fluorescent probes bearing cyclooctyne groups are synthesized, an organic dye-based probe and a quantum dotbased probe. Contrary to Cu(I)-catalyzed click chemistry, the developped methodology enables quantum dots’ functionalization while maintaining their high fluorescence quantum yield. Glass slides have also been coated with azides or nitrones, surfaces on which can be subsequently grafted cyclooctyne-probes. Fluorescent labelling of cell membrane’s sialic acids after metabolic incorporation of modified mannosamines has also been carried out in vitro to confirm the potential interest of strained-alkyne chemistry in biological conditions

Full textThe thesis focuses on the relationship the Beninese society entertains with pharmaceuticals. Based on the informal pharmaceutical market, a phenomenon particularly dynamic within the African French speaking countries, the main concern of this work is the description of current modes of pharmaceutical distribution in Benin and the way drugs are used by the Cotonou inhabitants. Whilst employing qualitative research methods combined with other methods inspired by quantitative ones, the research underlines the current importance of the marketable drug value among actors of pharmaceutical distribution in Cotonou. Ensuing high consumption leads often to self-medication, with speific objectives of health care (curative, preventive, health maintaining) yet in practice they rarely comply with biomedical recommandations. Finally, when comparing the modes of distribution existing in Benin and its anglophone neighbouring countries (Nigeria and Ghana), the study shows that the realities observed in Cotonou are operational on a more global scale

Full textAmorphous pharmaceuticals (excipients and active ingredients) are considered as one of the most promising approach to overcome the poor water solubility issue related to many drug molecules. Preparing poorly soluble drugs in the amorphous state is thus becoming an essential strategy for incorporating drugs into highly effective dosage forms. Recent developments have highlighted the need of a better understanding of the impact of preparation pathway onto the resulting amorphous solids. The aim of this thesis is to contribute to a rational knowledge of the differences in the amorphous state generated by two distinct preparation pathways: quenching from the melt and high-energy milling. Physico-chemical properties of the amorphous materials were studied using a set of analytical methods (structural, thermal and spectroscopic) coupled to quantum DFT calculations. It was demonstrated for two compounds of pharmaceutical interest that depending on the preparation methods, properties such as physical stability and crystallization kinetics might differ, leading to distinct behaviors upon storage. Melt-quenched states have been found to possess a good stability over time, while milled ones exhibit a lower stability resulting in an easier tendency toward crystallization. Moreover, beyond the glass transition temperature, it was outstanding to note that all discrepancies in physico-chemical properties are suppressed. Our findings indicate also that the propensity of both inspected molecular compounds to be amorphized rises as milling temperature decreases. This thesis also provides new insights to elaborate adequate stabilization protocols for amorphous pharmaceuticals

During this work, we have defined important SAR criteria, which led us to prepare such selective compounds. Compilation of those informations had led to the definition of the pharmacophore of I1Rs. We had also developed a method for the preparation of trifluoromethylamine derivatives, specially lactams, via a one-pot synthesis using a Barbier type reaction
