    Résumé : Rhinoviruses (RVs) have been linked to exacerbations of many pulmonary diseases, thus increasing morbidity and/or mortality in subjects at risk. Unfortunately, the wide variety of RV genotypes constitutes a major hindrance for the development of Rhinovirus replication inhibitors. In the current investigation, we have developed a novel series of pyrazole derivatives that potently inhibit the Rhinovirus replication. Compounds 10e and 10h behave as early stage inhibitors of Rhinovirus infection with a broad-spectrum activity against RV-A and RV-B species (EC50 < 0.1 mu M). We also evaluate the dynamics of the emerging resistance of these promising compounds and their in vitro genotoxicity. Molecular docking experiments shed light on the pharmacophoric elements interacting with residues of the drug-binding pocket.

    Résumé : The first TDAE-initiated reaction between benzonitrile derivatives as substrates and substituted benzaldehydes to form substituted hydroxyethylbenzonitrile derivatives is reported. The 2-hydroxyethyl benzonitrile derivatives thus formed were good candidates for one-pot lactonization in a mixture of hydrochloric acid and methanol at 70 degrees C over five hours. These reactions furnished the corresponding 3-substituted isochroman-1-one derivatives in good yields.

    Résumé : Manganese(III) acetate-mediated peroxycyclization between 2-hydroxy-3-methylnaphthoquinone and various alkenes was performed to obtain dihydronaphtho[2,3-c][1,2] dioxine-5,10(3H, 10aH)-diones. The reactivity of symmetrical or unsymmetrical 1,1-disubstituted alkenes and monosubstituted alkenes allowed the synthesis of more than 50 original molecules. Focusing on the excellent reactivity of 2-hydroxy-3-methylnaphthoquinone, we describe the first example of Mn(OAc)(3) reactivity with nitro-substituted alkenes. The scope, limitations and stereochemistry of the products synthesized are discussed. Starting from monosubstituted alkenes, the instability of a pair of diastereoisomers was observed, leading to ring opening.

    Résumé : Rhinovirus (RV), member of the Enterovirus genus, is known to be involved in more than half of the common colds. Through advances in molecular biology, rhinoviruses have also been associated with exacerbations of chronic pulmonary diseases (e.g. asthma, chronic obstructive pulmonary disease (COPD) and cystic fibrosis). In the current investigation, we develop a novel series of 4,5-dimethoxybenzyl derivatives that potently inhibits rhinovirus replication. Compound (S)-7f blocks RV-B14 replication with an EC50 value of 0.25 mu M and shows a low toxicity in HeLa cells (CC50 \textgreater 271 mu M). Enantioseparation followed by an absolute configuration determination by a Mosher's method revealed the interest of enantiopure compounds. Molecular docking studies permitted the identification of key biological interactions within the drug-binding pocket and an in silico drug-like study revealed a good potential for the development of these derivatives.

    Résumé : A mild and metal-free regiodivergent addition of carbon nucleophiles to alpha,beta-unsaturated electrophiles was developed. Total 1,2-regioselectivity was observed in the addition of nitrobenzyl chloride derivative 1 to alpha,beta-unsaturated aldehydes 2 in the presence of TDAE. Moreover, the reaction between p-nitrobenzyl chloride 1a and alpha,beta -unsaturated iminium salts 4 led to the formation of the 1,4-adduct with total regioselectivity.

    Résumé : Polymerization reactions with organic electron donors (OED) as initiators are presented herein. The metal-free polymerization of various activated alkene and cyclic ester monomers was performed in short reaction times, under mild conditions, with small amounts of organic reducing agents, and without the need for co-initiators or activation by photochemical, electrochemical, or other methods. Hence, OED initiators enabled the development of an efficient, rapid, room-temperature process that meets the technical standards expected for industrial processes, such as energy savings, cost-effectiveness and safety. Mechanistic investigations support an electron-transfer initiation pathway that leads to the reduction of the monomer.

    Résumé : Human rhinoviruses (HRV) are the predominant cause of common colds and flu-like illnesses, but are also responsible for virus-induced exacerbations of asthma and chronic obstructive pulmonary disease. However, to date, no drug has been approved yet for clinical use. In this study, we present the results of the structure-based lead optimization of a class of new small-molecule inhibitors that we previously reported to bind into the pocket beneath the canyon of the VP1 protein. A small series of analogues that we designed based on the available structure and interaction data were synthesized and evaluated for their potency to inhibit the replication of HRV serotype 14. 2-(4,5-Dimethoxy-2-nitrophenyI)-1-(4-(pyridin-4-yl)phenyl)ethanol (3v) was found to be a potent inhibitor exhibiting micromolar activity (EC50 = 3.4 +/- 1.0 mu M) with a toxicity for HeLa cells that was significantly lower than that of our previous hit (LPCRW_0005, CC50 = 104.0 +/- 22.2 mu M: 3v, CC50 > 263 mu M).

    Résumé : We report a novel series of quinoxaline derivatives from which agents with antiproliferative activity have been identified. Two ethyl 3-(arylethynyl)quinoxaline-2-carboxylates demonstrated substantial anti proliferative activity against both human non-small cell lung carcinoma (A549) and glioblastoma (U87-MG) cell lines. Pyrido[4,3-b]quinoxalin-1(2H)-ones demonstrated poor activity against A549 and U87-MG cell lines. Three of the derivatives in ethyl 3-(arylethynyl)quinoxaline-2-carboxylate series demonstrated substantial antiproliferative activity. The arylethynyl derivative 2a and 2d proved to be the most cytotoxic with an IC50 value of 3.3 mu M for both A549 and U87-MG cell lines. (C) 2016 Elsevier Masson SAS. All rights reserved.

    Résumé : Studies directed toward the oxidative and reductive desulfurization of readily available 2'-S-ary1-2'thiouridine derivatives were investigated with the prospect to functionalize the C2'-position of nucleosides. The oxidative desulfurization-difluorination strategy was successful on 2-(arylthio)allcanoate surrogates, while extension of the combination of oxidants and fluoride sources was not an efficient fluorination protocol when applied to 2'-S-aryl-2'-thiouridine derivatives, resulting mainly in C5 halogenation of the pyrimidine ring and C2'-monofluorination without desulfurization. Cyclic voltammetry of 2'-arylsulfony1-2'-deoxyuridines and their 2'-fluorinated analogues showed that cleavage of the arylsulfone moiety could occur, although at relatively high cathodic potentials. While reductivedesulfonylation of 2'-arylsulfciny1-2'-deoxyuridines with organic electron donors (0EDs) gave predominantly base-induced furan type products, chemical (OED) and electrochemical reductivedesulfonylation of the cc-fluorosulfone derivatives yielded the 2'-deoxy-2'-fluorouridine and 2',3'-didehydro-2',3'-dideoxy-2'-fluorouridine derivatives. These results provided good evidence of the generation of a C2'-anion through carbon-sulfur bond cleavage, opening new horizons for the reductivefunctionalization approaches in nucleosides.

    Résumé : We report here a practical and metal-free synthesis of novel enantiopure amides containing the drug-like 5-nitroimidazole scaffold. The first step was a metal-free diastereoselective addition of 4-(4-(chloromethyl) phenyl)-1,2-dimethyl-5-nitro-1H-imidazole to enantiomerically pure N-tert-butanesulfinimine. Then, the N-tert-butanesulfinyl-protected amine was easily deprotected under acidic conditions. Finally, the primary amine was coupled with different acid chlorides or acids to give the corresponding amides. The mild reaction conditions and high tolerance for various substitutions make this approach attractive for constructing pharmacologically interesting 5-nitroimidazoles.

    Résumé : One-electron reduction is commonly used in organic chemistry for the formation of radicals by the stepwise transfer of one or two electrons from a donor to an organic substrate. Besides metallic reagents, single-electron reducers based on neutral organic molecules have emerged as an attractive novel source of reducing electrons. The past 20 years have seen the blossoming of a particular class of organic reducing agents, the electron-rich olefins, and their application in organic synthesis. This Review gives an overview of the different types of organic donors and their specific characteristics in organic transformations.

    Résumé : Silver nanoparticles (Ag NPs) of different sizes from 9 to 17 nm were synthesized by Creighton method and characterized using UV-vis spectroscopy and high resolution transmission electron microscopy (HRTEM). Fluorescence quenching of 1,4-dimethoxy-2,3-dibromomethylanthracene-9,10-dione (DMDBMAD) in methanol has been studied by fluorescence spectroscopy combined with UV-vis absorption spectroscopic techniques. It has been observed that the fluorescence intensity of DMDBMAD decrease with increase in the size of the Ag NPs. The quenching rate constant and association constant were determined using Stern-Volmer and Benesi-Hildebrand plots. The Stern-Volmer plot suggested that the quenching of DMDBMAD fluorescence by silver NPs was a dynamic process. The obtained value of the association constant infers that there is an association between DMDBMAD and the Ag NPs. Using Forster resonance energy transfer (FRET) theory, the distance between the donor (DMDBMAD) to acceptor (Ag NPs) and the critical energy transfer distance were obtained. Long range dipole-dipole interaction between the excited donor and ground state acceptor molecules is the dominant mechanism responsible for the energy transfer.

    Résumé : Objectives: To study the characteristics and the mode of action of the anti-rhinovirus compound 4-[ 1-hydroxy-2( 4,5-dimethoxy-2-nitrophenyl) ethyl] benzonitrile (LPCRW_0005). Methods: The antiviral activity of LPCRW_0005 was evaluated in a cytopathic effect reduction assay against a panel of human rhinovirus (HRV) strains. To unravel its precise molecular mechanism of action, a time-of-drugaddition study, resistance selection and thermostability assays were performed. The crystal structure of the HRV14/LPCRW_0005 complex was elucidated as well. Results: LPCRW_0005 proved to be a selective inhibitor of the replication of HRV14 (EC50 of 2+ 1 mM). Time-ofdrug- addition studies revealed that LPCRW_0005 interferes with the earliest stages of virus replication. Phenotypic drug-resistant virus variantswere obtained (>= 30-fold decrease in susceptibility to the inhibitory effect of LPCRW_0005), which carried either an A150T or A150V amino acid substitution in the VP1 capsid protein. The link between the mutant genotype and drug-resistant phenotype was confirmed by reverse genetics. Crossresistance studies and thermostability assays revealed that LPCRW_0005 has a similar mechanism of action to the capsid binder pleconaril. Elucidation of the crystal structure of the HRV14/LPCRW_0005 complex revealed the existence of multiple hydrophobic and polar interactions between the VP1 pocket and LPCRW_0005. Conclusions: LPCRW_0005 is a novel inhibitor of HRV14 replication that acts as a capsid binder. The compound has a chemical structure that is markedly smaller than that of other capsid binders. Structural studies show that LPCRW_0005, in contrast to pleconaril, leaves the toe end of the pocket in VP1 empty. This suggests that extended analogues of LPCRW_0005 that fill the full cavity could be more potent inhibitors of rhinovirus replication.

    Résumé : Human rhinoviruses are a common cause of respiratory infections, and thus constitute an important target for medicinal chemistry. Still, no drug has been approved for clinical use. We report herein the discovery of dibenzenic derivatives with potent and specific in vitro anti-rhinoviral 14 activity. A total of 99 structural analogues were synthesized by an original synthesis method, i.e. through one organic agent Tetrakis(DimethylAmino)Ethylene (TDAE) and a structure-activity relationship was established. It was shown that 4,5-dimethoxy scaffold and the presence of a C-4 substituted aromatic moiety were necessary to the in vitro activity of these original agents. However, modifications on liker were not convincing. The benzonitrile derivative 23 was identified as the most potent and selective inhibitor of rhinovirus replication in these series (EC50 of 2 +/- 0.5 mu M, CC50 of 184 mu M, selectivity index of 92).

    Résumé : We report here the first example of a Long-Distance S(RN)1 (LD-S(RN)1) reaction on a propargylic chloride. The reaction of 1-(3-chloroprop-1-ynyl)-4-nitrobenzene (1) with nitronate anions led to both the formation of the C-alkylation product through an LD-S(RN)1 mechanism and the ethylenic compound resulting from nitrous acid elimination on the C-alkylation product 2. In contrast with previous work on LD-S(RN)1 reactivity, no O-alkylation product was observed. Only one original product 4 was isolated under phase transfer conditions, resulting from a nucleophilic attack by 2-nitropropane anion on the electrophilic allcyne. This LD-S(RN)1 reactivity did not extend to sulfinate anions: the reaction of 1 with sulfinate anions yielded original ethylenic disulfone compounds which were formed via an ionic process.

    Résumé : Since 1976, fibrin glues have been attracting medical interest, spreading from their initial use as a hemostatic agent in cardiovascular surgery to other fields of surgery. Studies have compared the efficacy of fibrin glues vs sutures in surgery. However, few comparisons have been made of the efficacy and safety of the different fibrin glues commercially available. Recently, fibrin glues have been tested as a scaffold delivery system for various substances inside the body (drugs, growth factors, stem cells). The infectious risk (viruses, new germs) of this blood-derived product was also studied in assays on viral inactivation methods. The development of autologous fibrin glues offers a solution to the problem of infectious risk. This review examines the current state of knowledge on the efficacy, safety and future potential of fibrin glues.

    Résumé : Efficacy and Future of the Aerosoltherapy in the Treatment of Cystic Fibrosis Patients Infected by Pseudomonas aeruginosa. Pseudomonas aeruginosa is considered as the most redoubtable pathogenic agent at cystic fibrosis patients. Its eradication is a priority to avoid the passage to chronic infection, the real turning point of the disease. For this, a wide therapeutic panel of intravenous antibiotics exists, and for some years, the research teams concentrate more and more on the inhaled way. The synthesis of the literature data presented herein focuses on both already experienced molecules (colistin and tobramycin), and on new therapeutics. This review aims at loosening advantages and inconveniences of each of these therapeutic options, while bringing to light the necessity of follow-up studies in order to prove the therapeutic interests of molecules in development.

    Résumé : We report herein the first example of a SNAr reaction using TDAE-initiated carbanions in quinazoline series. The o-nitrobenzyl carbanion, formed by the action of TDAE on o-nitrobenzyl chloride, reacts with 4-chloro-2-trihalomethylquinazolines 4 and 5 via a SNAr mechanism. This enabled a new series of 4-benzyl-2-trihaloquinazoline derivatives to be synthesized in good yields under mild reaction conditions offering promising prospects for pharmacomodulation.

    Résumé : New reductive alkylating agents in 4- and 5-nitroimidazole series produce exclusively O-alkylation with nitronate anions under classical S(RN)1 conditions at room temperature. Electron-transfer C-alkylation is observed under microwave irradiation or under conventional heating. Furthermore, X-ray spectroscopy shows that the dihedral angles between the phenyl and imidazole rings for the two series are different, which could greatly influence reactivity in 4- and 5-nitroimidazole series.

    Résumé : The synthesis of the title compounds was achieved using ethyl 2-amino-6-methyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxylate (1) as starting material. The reaction of the amino ester 1 with phenylisothiocyanate in boiling ethanol afforded the thiourea derivative 5. The cyclization reactions of 5 under different reaction conditions led to different pyridothienopyrimidine derivatives. Other reactions of the latter derivatives leading to pyrido[4 ',3 ': 4,5]thieno[2,3-d]triazolo[1,5-a]pyrimidines are also presented.

    Résumé : We report herein the first tetrakis(dimethylamino) ethylene (TDAE)-mediated double addition of nitrobenzylic anions to aromatic dialdehydes such as terephthalaldehyde and isophthalaldehyde, and have developed a new methodology that allows us to observe the double addition. This TDAE-mediated approach is an original and mild method with which to generate tri-aromatic diols.

    Résumé : A series of new imidazo[2,1-b]thiazoles was prepared in moderate to good yields in a four step synthesis using the TDAE methodology from 6-chloromethyl-5-nitroimidazo[2,1-b]thiazole and keto esters, ketomalonates and ketolactams. All compounds were tested for their antibacterial and antifungal activities against four bacterial strains (two Gram positive and two Gram negative ones) and four yeasts. Among these synthesized 5-nitroimidazo[2,1-b]thiazoles, the compounds I and 6 showed potent antimicrobial activities against all candida. strains and compound 3e showed an interesting antifungal potential against Candida tropicalis.

    Résumé : Few studies show the reluctance of the people to get vaccinated against A (H1N1) influenza for fear of side effects of squalene (MF59, AS03, AF03) and thimerosal. The aim of this paper is to assess the safety in using these adjuvants and preservative reviewing data of clinical trials relative to wich formulation includes these compounds. In the current state of knowledge, these vaccines have proved to be effective even though they more frequently give local adverse events than non-adjuvanted influenza vaccines. Systemic side effects are generally not serious. In the studies, adjuvanted vaccines do not increase neither the risk of Guillain Barre syndrome nor auto-immune diseases. There is no convincing evidence that exposure to thimerosal in vaccines had any deletorious effect on physiological outcome.

    Résumé : We present herein an extension of the TDAE strategy using original heterocyclic carbaldehyde as electrophiles. We also evaluate the influence of the presence of nitro group on the reactivity. The TDAE-initiated reactions of various halomethyl and gem-dihalomethyl derivatives with non-nitrated carbaldehyde 1 or 2 formed the expected products accompagnied by original rearranged products while the presence of a nitro group just like the carbaldehyde 21 furnished only the expected products in good yields.
