Van, Hijfte Nathalie. "Conception et synthèse de nouveaux inhibiteurs potentiels de la protéine mTOR." Le Havre, 2011. http://www.theses.fr/2011LEHA0007.
Full textMammalian target of Rapamycin (mTOR) is a protein kinase, involved in the PI3K/Akt/mTOR signaling pathway, which controls cell growth, proliferation, and cellular survival. This pathway is often deregulated in cancer, and there is a great interest in developing drugs that target the protein mTOR. During the last ten years, a new inhibition mode has been highlighted: it consists in the competitive and selective inhibition of the catalytic site of mTOR. The aim of this PhD project was to design and synthesize new compounds, from a common tricyclic scaffold, able to interact with the ATP pocket of mTOR. The synthesis of a new scaffold has also been determined during this work. Biological evaluations were performed in laboratories of our industrial partner (Janssen) as well as the National Cancer Institute (NCI)

Full textThe protein kinase family is one of the most pursued classes of therapeutic targets in the pharmaceutical industry. It is also one of the most challenging families since many kinase inhibitors are rejected from clinical trials, because of either selectivity problems or a lack of efficacy. The recent success of a few covalent inhibitors of EGFR kinase indicates that this new generation of inhibitors could solve both of these problems at the same time, by reacting with an unconserved cysteine residue of the ATP binding site using an electrophilic group attached to the ligand, and providing high affinity. In order to investigate the opportunities for the design of covalent inhibitors addressing other members of the kinase family, our main focus consisted in automatically identifying all human kinases bearing a reactive cysteine in their binding site. Since the shape of the binding site depends on the kinase conformation, we performed a preliminary study to distinguish the different adopted conformations among all the available kinase 3D structures. With our results in hand, we designed a inhibitor liable to covalently bind and inactivate KIT kinase by reacting with a cysteine residue specific to a small kinase subset and accessible only in the inactive “DFG out” kinase conformation that KIT can adopt. The covalent bond between our inhibitor and KIT was confirmed by mass spectrometry. Activity assays on a large panel of kinases confirmed the affinity of this inhibitor for KIT and its very good selectivity profile. Finally, this work gives insights on how to design a new generation of highly selective and efficient kinase inhibitors

Full textThis manuscript describes the synthetic development of symmetric heterocyclic systems miming the pentamidine. The first part is a current inventory of the malaria, in particular on the physiopathological aspects, the drugs and the resistance. Then are described protein kinases, their role in cells and their interest in the discovery of new inhibitors of protein kinases for the development of new drugs. Finally the end of this part concerns the description and the use of the microwave technology as useful tool for thermal activation in organic synthesis. The second part is the synthetis of bis-(5-arylidène imidazolinone)bridged and symmetric diamines using solventless microwave reaction conditions. The spacer-arm between the two heterocyclic entities are diamines as ethylenediamine, piperazine and 1,4-bis(3-aminopropyl piperazine. This approach was then extended to the synthesis of bis(5-arylidène thiazolidinone)diamines using the same spacer-arms in this third part. Then, the use of a one-pot three component reaction under microwave irradiation allowed to the preparation of new bis-(5-arylidène rhodanine)diamines and 5-arylidène thiazolidine-4-ones functionalized in position N-3 with various alkylamino chains. Finally the biological activity of all of these compounds have been evaluated for a structure/activity relationship (SAR) study: - inhibition of proteins kinases (CDKs, DYRKs, CLKs, GSK-3, PI3k, etc. ) - in vitro antiproliferative activities on cells, - in vitro assessment of antimalarial activity. Several molecules have been identified as active with IC50 < 0. 1 mM for DYRK1A and IC50 ~ 100 mM for in vitro antimalarial activity

Full textIn 1950’s protein kinases were found to play a critical role in cell signaling, rising strong research potential for this enzyme family. Initially investigated for their implications in cancerogenesis they were more recently found to be involved in a wide variety of diseases including neurodegenerative pathologies. Herein will be presented two research projects that offer bright new perspectives for the inhibition of kinases involved whether in neurodegenerative diseases or cancers.First, the design and synthesis of new pyrido[3,4-g]quinazoline derivatives will be described as well as their protein kinase inhibitory potencies toward five CMGC family members (CDK5, CK1, GSK3, CLK1 and DYRK1A) that are known to play a potential role in Alzheimer’s disease. The interest for this original tricyclic heteroaromatic scaffold as modulators of CLK1/ DYRK1A activity was validated by nanomolar potencies. CLK1 co-crystal structures with two inhibitors revealed the binding mode of these compounds within the ATP-binding pocket and led to the synthesis of new diversely substituted pyrido[3,4-g]quinazolines.Then the synthesis of a new derivative of the staurosporine aglycon (K252c), in which the lactam ring was replaced by a pyrazole moiety, will be depicted. The resulting indolopyrazolocarbazole inhibited Pim isoforms 1–3 whereas it did not impair the activity of two known targets of K252c, protein kinase C isoforms α and γ . The lead compound exhibited same cytotoxic activity as K252c toward both human leukemia and colon carcinoma cell lines (K562 and HCT116), strongly suggesting that this new scaffold deserves further investigations for treatment of malignancies associated with kinases activities

Full textChronic pain is a global public health priority which affects more than 20% of Europeans. Mechanical allodynia, a pain in response to normally innocuous stimuli, is one of the most prevalent pain symptoms. Despite intensive research toward the study of pain mechanisms, currently available treatments of pain are not always effective, and can produce side-effects. In this context, the aim of the project is to design, synthesize and evaluate selective inhibitors of protein kinases for the treatment of mechanical allodynia. During this PhD work, new selective inhibitors of the protein kinase p38α has been discovered. This protein kinase is known for its implication in chronic pain and mechanical allodynia. A structure-activity relationship study was performed to identify the important structural features allowing a gain of activity of molecules in vitro and in vivo using an animal model. The best compounds showed submicromolar IC50 values toward p38α and a strong inhibition of mechanical allodynia in vivo

Full textAccording to the International Agency for Research on Cancer, cancer is the first cause of death in France with about 150 000 deaths estimated in 2012. This disease is characterized by anarchistic and uncontrolled proliferation of cells that escape control mechanisms. Currently, the anticancer drugs target mainly the cancerous cells that overexpress proteins, such as growth factor receptors with tyrosine kinase activity.Our work is mainly carried on four of these receptors: EGFR (Epidermal Growth Factor Receptor), VEGFR (Vascular Endothelial Growth Factor Receptor), PDGFR (Platelet-Derived Growth Factor Receptor) and c-Kit receptor. Several heterocycles (quinazoline, benzotriazine, thienopyrimidine) differing by their aniline or aryloxy moiety in C-4 position were designed, synthesized and evaluated. Among these products, the 4-aryloxyquinazolines substituted by aminoalkoxy chains in C-7 position have the characteristic to be potent inhibitors of VEGFR, PDGFR and c-kit receptor with high anti-angiogenic potency. Simultaneously, 2-aminoquinazoline derivatives were designed. These compounds substituted by various anilines in C-4 position showed interesting antiproliferative activity through their intercalation between the pairs of DNA bases

Full textIn a drug design project, improving the prediction of affinity is still an issue despite the considerable efforts made in this direction. In addition, binding kinetic constants are of major interest for the discovery of new drugs, in particular at the early stage of molecules optimization to better evaluate their tolerance and efficacy. Due to the recent emergence of the importance of binding kinetics, methods of kinetic rates prediction remain scarce and no efficient computational approach has still been developed to correctly estimate kinetic parameters.In order to challenge these two problematics, the first part of this thesis consists in the development of new methods that allow, first, to improve the prediction of affinity by a flexible docking and, second, to predict the ligand binding/unbinding pathways and binding kinetic rates (kon and koff) by enhanced molecular dynamics simulations.In the second part of this thesis, we have designed novel inhibitors of LIM kinases, emerging targets involved in several pathophysiologies including neurofibromatosis and cancer. Our compounds have good affinities and selectivities in vitro, and excellent activities and tolerances evaluated on cellular tests

Full textApicomplexan parasites are ubiquitous and have a strong incidence in veterinary and human medicine. Some of them, like Plasmodium falciparum, causing malaria, or Toxoplasma gondii, causing toxoplasmosis, are matter of public health concern. The existing therapies may have limited efficiency, high toxicity, and may lead to resistance, highlighting the necessity of new more specific approaches. In this context, we have developed two approaches to inhibit Apicomplexa: -the synthesis of biphenylimidazoazines with broad-spectrum and efficient at the micromolar range on five different apicomplexan parasites in vitro. -the synthesis of imidazo[1,2-b]pyridazines specifically targeting a kinase protein (CDPK1) of T. gondii and efficient at the submicromolar range on the parasite in vitro. More than 90% diminution of parasite burden in mice and short term safety make these imidazo[1,2-b]pyridazines good therapeutic candidates
Juillet, Charlotte. "Conception, synthèse et évaluation pharmacologique d’analogues simplifiés de métabolites marins, inhibiteurs de la kinase Aurora B, à visée anticancéreuse." Thesis, université Paris-Saclay, 2020. http://www.theses.fr/2020UPASF019.
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 textNeurofibromatosis 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
