  • Publication number: 20230322804
    Abstract: The present invention concerns reagents for the reversible protection of biological molecules. It relates in particular to compounds derived from azaisatoic anhydride and their uses for the protection of biological molecules, particularly enzymes, in order to block their activity. The invention also relates to the biological molecules protected in this manner and to the methods for making use of these reagents.

  • Publication number: 20220074930
    Abstract: The present invention relates to a method for capturing a molecular target present in the aqueous phase of a water-in-oil emulsion, said method being based on the use of a binding system comprising (a) a surfactant bearing a functional moiety on its hydrophilic head group and (b) a chemoprobe that acts as a molecular staple between the functionalized surfactant and the molecular target and comprises at least two distinct domains namely (i) at least one capture moiety which is able to specifically bind the molecular target and (ii) at least one binding domain which is able to interact with the functional group of the surfactant through covalent or non-covalent interactions, directly or through a binding intermediary.

  • Publication number: 20190112329
    Abstract: A method of functionalizing RNA in a liquid sample includes reacting an anhydride function of a binding molecule with at least one RNA molecule at one or more hydroxyl groups in any of position 2? of a ribose of any nucleotide of the RNA molecule, position 2? of the ribose of the terminal nucleotide at the 3? end of the RNA molecule, or position 3? of the ribose of the terminal nucleotide at the 3? end of the RNA molecule, to obtain functionalized RNA. The binding molecule includes an aza-isatoic anhydride or derivative thereof linked to a group of interest by a linkage, and an aza-anthranilate is formed from reacting the anhydride function of the binding molecule with a hydroxyl group of the RNA molecule so as to join the RNA molecule to the group of interest. The group of interest is a marker, labelling precursor, or ligand.

  • Patent number: 10174068
    Abstract: The present invention relates to a method of functionalization of at least one ribonucleic acid (RNA) molecule, contained in a liquid sample, which includes the following steps: a) providing at least: one binding molecule consisting of an aza-isatoic anhydride or a derivative thereof, one group of interest, and one linkage joining the binding molecule to the group of interest, b) reacting the anhydride function of the binding molecule with at least one hydroxyl group carried: in position 2? of the ribose of one of the RNA nucleotides, and/or in position(s) 2? and/or 3? of the ribose of the nucleotide at the terminal 3? end of the RNA, and obtaining an aza-anthranilate that joins, by means of the linkage, the RNA to the group of interest.
