An enzymatic activation of formaldehyde for nucleotide methylation

Autor: Charles Bou-Nader, Frederick W. Stull, Ludovic Pecqueur, Philippe Simon, Vincent Guérineau, Antoine Royant, Marc Fontecave, Murielle Lombard, Bruce A. Palfey, Djemel Hamdane

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-8 (2021)

The bacterial thymidylate synthase ThyX catalyzes the reductive methylation of deoxyuridylate (dUMP) into deoxythymidylate (dTMP) and requires both folate and flavin for activity. Here, the authors combine biochemical experiments, spectroscopic measu

Impact of the gut microbiota on the m6A epitranscriptome of mouse cecum and liver

Autor: Sabrina Jabs, Anne Biton, Christophe Bécavin, Marie-Anne Nahori, Amine Ghozlane, Alessandro Pagliuso, Giulia Spanò, Vincent Guérineau, David Touboul, Quentin Giai Gianetto, Thibault Chaze, Mariette Matondo, Marie-Agnès Dillies, Pascale Cossart

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-16 (2020)

The intestinal microbiota modulates host physiology and gene expression via unclear mechanisms. Here, Jabs et al. show that variations in the gut microbiota correlate with N6-methyladenosine modifications of host mRNAs in the cecum and liver of mice.

Grafting of Anionic Decahydro-Closo-Decaborate Clusters on Keggin and Dawson-Type Polyoxometalates: Syntheses, Studies in Solution, DFT Calculations and Electrochemical Properties

Autor: Manal Diab, Ana Mateo, Joumada El Cheikh, Zeinab El Hajj, Mohamed Haouas, Alireza Ranjbari, Vincent Guérineau, David Touboul, Nathalie Leclerc, Emmanuel Cadot, Daoud Naoufal, Carles Bo, Sébastien Floquet

Publikováno v: Molecules, Vol 27, Iss 22, p 7663 (2022)

Herein we report the synthesis of a new class of compounds associating Keggin and Dawson-type Polyoxometalates (POMs) with a derivative of the anionic decahydro-closo-decaborate cluster [B10H10]2− through aminopropylsilyl ligand (APTES) acting as b

Synthesis of novel isoxazolines and isoxazoles of N-substituted pyrazolo[3,4-d]pyrimidin-4(5H)-one derivatives through [3+2] cycloaddition

Autor: Ameur Rahmouni, Anis Romdhane, Abderrahim Ben said, Vincent Guérineau, David Touboul, Hichem Ben Jannet

Publikováno v: Arabian Journal of Chemistry, Vol 12, Iss 8, Pp 1974-1982 (2019)

3,6-Dimethyl-1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one 3 was prepared by an intramolecular cyclization of N-(4-cyano-3-methyl-1-phenyl-1H-pyrazol-5-yl) acetamide 2 in ethanol in the presence of piperidine. N-allylation and N-propargyl alkylation

The synthesis and characterization of giant Calixarenes

Autor: Vincent Guérineau, Marion Rollet, Stéphane Viel, Bénédicte Lepoittevin, Ludovic Costa, Pascale Saint-Aguet, Régis Laurent, Philippe Roger, Didier Gigmes, Cyril Martini, Vincent Huc

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-14 (2019)

Calixarenes are cyclic oligomers obtained by condensation reactions between phenols and formaldehyde and usually include up to eight phenolic subunits. Here the authors demonstrate the synthesis of calixarenes with up to 90 phenolic subunits with up

Classification of Environmental Strains from Order to Genus Levels Using Lipid and Protein MALDI-ToF Fingerprintings and Chemotaxonomic Network Analysis

Autor: Marceau Levasseur, Téo Hebra, Nicolas Elie, Vincent Guérineau, David Touboul, Véronique Eparvier

Publikováno v: Microorganisms, Vol 10, Iss 4, p 831 (2022)

During the last two decades, MALDI-ToF mass spectrometry has become an efficient and widely-used tool for identifying clinical isolates. However, its use for classification and identification of environmental microorganisms remains limited by the lac

Tuning the nuclearity of [Mo2O2S2]2+-based assemblies by playing with the degree of flexibility of bis-thiosemicarbazone ligands

Autor: Diana Cebotari, Sergiu Calancea, Jerôme Marrot, Régis Guillot, Clément Falaise, Vincent Guérineau, David Touboul, Mohamed Haouas, Aurelian Gulea, Sébastien Floquet

Publikováno v: Dalton Transactions. 52:3059-3071

Two families of binuclear or tetranuclear [MoV2O2S2]2+-based thiosemicarbazone complexes are obtained by varying the rigidity/flexibility of bis-thiosemicarbazone ligands.

Stereoselective Ring-Opening (Co)polymerization of β-Butyrolactone and ε-Decalactone Using an Yttrium Bis(phenolate) Catalytic System

Autor: Jiraya Kiriratnikom, Carine Robert, Vincent Guérineau, Vincenzo Venditto, Christophe M. Thomas

Publikováno v: Frontiers in Chemistry, Vol 7 (2019)

An effective route for ring-opening copolymerization of β-butyrolactone (BBL) with ε-decalactone (ε-DL) is reported. Microstructures of the block copolymers characterized by 13C NMR spectroscopy revealed syndiotactic-enriched poly(3-hydroxybutyrat
