Texto completoAt this beginning of 21th century, the cancer makes several million victims in the world every year. If this disease asserts itself as a problem of public health, the economic concern which it exercises with societies isnot less important.Carbazoles and Pyrroloirninoquinones are families of very diversified molecules belonging to alkaloids,being able to offer numerous therapeutic activities in particular as anticancer drugs.If the list of the known active molecules and their treatments connected to the molecules of natural orsynthetic origin is long, it seems c1 early that the research for new structures remains important even today topropose of new treatment or to understand better this pathology. In our approach and through diverse objectives of chemical interest, this report present the synthesis of variouscompounds, analogues of these natural molecules with potentiel antitumoral properties, with as particularity the 4,4-dimethyl-1 ,2,3,4-tetrahydroquinoleine pattern

Texto completoThe access to new original biologically active heterocyclic compounds, is one of the main objectives of our research group. In this context, the main purpose of this thesis is the design of three new families of heterocyclic compounds containing a pyrazolic motif that may exhibit biological activities, namely pyrido[1',2': 1.5]pyrazolo[4,3-d]pyrimidine, pyrrolo[3,4-c]pyrazole and pyrazolo[5,1-b]thiazole.This manuscript is essentially dedicated to a methodology work describing the different routes of access to these originals and potentially modular tricyclic and bicyclic precursors. The reactivity of these key synthons is then studied towards aromatic nucleophilic substitutions reactions and various pallado-catalyzed methods of functionalization (Activation with PyBrOP- (hetero) arylation, Liebeskind-Srogl, Suzuki-Miyaura, Buchwald-Hartwig, C-H arylation, aromatic nucleophilic substitution) to develop interesting libraries built around these unusual structures, thus opening numerous pharmacological perspectives

Texto completoNeurofibromatosis type 1 (NF1) is a genetic disease characterized by the development of cutaneous neurofibromas (cNF) (benign tumors) located at nerve endings. LIM kinases (LIMKs), enzymes responsible for cytoskeleton dynamics, have emerged in recent years as valid therapeutic targets for this disease. These enzymes are overactivated in several pathologies including NF1, glioblastoma or osteosarcoma. A medicinal chemistry project was therefore initiated with the aim of designing new selective inhibitors of LIMKs. Initially, structure-activity relationship (SAR) studies were conducted on the 3 main pharmacomodulation sites of the pyrrolopyrimidine-type compounds previously developed by our team. The development of various synthetic strategies was undertaken, allowing efficient access to a large number of final products (84). Optimization of the aniline portion of the compounds led to the synthesis of 49 LIMKs inhibitors, with inhibition constants lower than 5 nM for several derivatives. Subsequently, an optimized 15 steps synthetic route was developed to replace the previously unchanged central ring 3,6-dihydropyridine with a derivative of 1-aminocyclohex-3-ene-1-carboxylic acid. Finally, a new series of inhibitors was developed by replacing the heterocyclic pyrrolo[2,3-d]pyrimidine base by 7-azaindole derivatives. Improved LIMK vs. ROCK selectivity was observed among the 23 obtained products. Following extensive in vitro evaluation of our best inhibitors on several cell lines, two compounds were selected for in vivo trials on an original mouse model of NF1. In parallel, new modes of LIMKs inhibition were developed with the synthesis of an irreversible inhibitor targeting LIMK1, as well as 4 PROTACs that induced LIMKs degradation through the ubiquitin-proteasome system in several cell lines

Texto completoIn an effort to develope new inhibitors of kinases as anticancer agents, we synthetized original indirubins and azaindirubins substituted in position 5, 5’, 6 and 7. Because of the poor water solubility and low bioavailability, monoxime analogs were also prepared. The effect on cyclin dependant kinase, glycogene synthase kinase-3 and on the survival of human neuroblastoma SH-SY5Y cells were estimated. On the other hand, we synthetized thiazoloindolo[3,2-c]quinolin which are closed to natural alcaloid. We reinvestigated the Graebe-Ullmann condensation under micro-wave. A new scaffold 7H-4,5-diaza-benzo[de]anthracen which is structurally closed to dercitin, a marine alkaloid, was identified. The effect on breast cancers cells, potential DNA intercalating and topoisomerase inhibition were also discussed

Texto completoThe discovery of new candidates to fight against various diseases, namely cancer and neurodegenerative diseases, is one of the main goals of our research group. In this context, the main purpose of this thesis, is the design of two new classes of heterocyclic planar structure, to date, rarely studied, namely pyrido[2’,1’ :1,5]pyrazolo[3,4-d]pyridazines and pyrido[2’,1’ :1,5]pyrazolo[3,4-d]pyrimidines. This manuscript is essentially dedicated to a methodology work describing the different routes of access to these originals and potentially modular tricyclic precursors. The reactivity of these key synthons is then studied towards aromatic nucleophilic substitutions reactions and various palladocatalyzed methods of functionalization (Suzuki-Miyaura, Buchwald-Hartwig, activation PyBrOP-(hetero) arylation) to develop interesting libraries built around these unusual structures, thus opening numerous pharmacologicals perspectives

Texto completoNew potential antitumor arylthiazoles have been prepared via 4,5-dichloro-1,2,3-dithiazolium chloride chemistry from aromatic amines as starting material. Reaction of cyclisation of iminodithiazole to benzothiazole has been optimised and scalling up under micro-wave irradiation was performed. The synthesis of a natural benzothiazole has been reinvestigated with luciferine derivatives. According several methodologies solvant free, thiazolocoumarins have been isolated. New plan and linear bis-2-cyanobenzothiazoles have been obtained via Appel salt chemistry with bis-amines as starting material and by coupling reaction using Cu or Ni. The synthetic route to and a preliminary biological evaluation of novel indolo[1,2-c]quinazolines and benzimidazo[1,2-c]quinazolines are described. The products were obtained by condensation of the appropriate diamines(e. G. 2-(2-aminophenyl)indole or 2-(2-aminophenyl)benzymidazole) with benzothiazole-2-carbonitriles. Topoisomerase inhibition of thiazolocompounds has been discussed. Moreover, original indirubin and thiazolotetralone derivatives have been prepared and tested against cyclin dependant kinases

Texto completoSupramolecular chemistry consists of molecular architecture complex organized thanks to a combination of non-covalent interactions. At the natural state, these structures have numerous functions such as cell energy production thanks to the ATP synthase or the genetic support thanks to a polyanion, the DNA molecule. Anions can be involved in radiotherapy through iodide. By opposition, it can also be associated with environmental disasters (Fukushima explosion in 2011) or some diseases (thyroid disease). In front of these troubles, it is a priority to fight against theses disastrous events. This PhD work has focused on the construction of boronium type macrocycle able to strongly trap iodide which is an anion model to study astatide trapping. This coordination is done thanks to hydrogen bonding and ionic interactions collaboration. Based on previous works realized in our laboratory in 2010, complexation properties of Calix-carBIB were studied. In a second time, new functionalized groups were used to study their potential for different applications such as astatide purification, water solubility and vectorization. Finally, a new receptor generation was studied, showing a better affinity for astatide

Texto completoDeregulation of protein kinases leads to numerous pathologies such as cancers and neurodegenerative diseases. In order to identify new scaffolds able to inhibit this proteins we synthesized new 3-alkenyl-oxindoles. By the mean of Appel’s salt chemistry, we develop a new synthetic route to this skeleton. Our approach allows variation of the substituent of the exocyclic akene which can be functionalized by heterocycles, amino-nitriles or thio-nitrile which are obtained after selective ring opening of (1,2,3)-dithiazoles. In another part, given powerful indirubin kinase inhibitory potency, we synthesized new analogs indiribunoids and isoindigoids. In both cases (3-akenyl-oxindoles from Appel’s salt chemistry and indigoids), the aromatic ring were substituted by various electron withdrawing group and nitrogen were incorporated to determinate structure activity relationship. All this 80 original 3-alkenyl-oxindoles were evaluated for their ability to inhibit kinase activity and cell proliferation
