  • Publication number: 20210052566
    Abstract: In the present invention, the proteomic identification of HBc interacting factors in the nucleus of human hepatocytes revealed a majority of RNA-binding proteins (RBPs) intervening in mRNA metabolism and especially, the serine/arginine-rich splicing factor (10) (SRSF1O) which was found enriched nearly (3000) times in HBc complexes. Inventors demonstrated that the inhibition of SRSF1O phosphorylation with the small molecule 1C8 (4-pyridinonebenzisothiazole carboxamide) induces a strong inhibition of HBV replication (genotypes C and D) in persistently-infected hepatocytes, as well as to a strong inhibition of the establishment of HBV cccDNA in de novo infection settings. Accordingly the present invention relates to an inhibitor of SRSF1O activity for use in the treatment of Hepatitis B virus (HBV) infection said inhibitor maintain SRSF1O in a dephosphorylated state and prevents or reduces the splicing activity of SRSF1O.

  • Patent number: 9089515
    Abstract: Long chain N-alkyl amino and imino compounds, oxa-substituted derivatives thereof, and pharmaceutical compositions including such compounds are described. The long chain N-alkyl group is a C8-C16 alkyl group. The long chain N-alkyl compounds and oxa-substituted derivatives thereof can be used in the treatment of viral infections, in particular hepatitis B virus or hepatitis C virus, in a cell or an individual. For example, the long chain N-alkyl compounds or oxa-substituted derivatives thereof can be derived from piperidines, pyrrolidines, phenylamines, pyridines, pyrroles, or amino acids.

  • Publication number: 20090004137
    Abstract: The invention relates to the use of an uridine derivative of formula (I); wherein —R1 represents monohalogenated alkynyl or dihalogenated alkenyl; —R2 is chosen from among hydrogen, hydroxyl, O-alkyl, O—CO alkyl and halogen; —R3 is chosen from among hydrogen, hydroxyl, O-alkyl, O—CO alkyl, halogen, SH, S-alkyl and N3; and —R4 is chosen from among hydroxyl, O-alkyl, O—CO alkyl, O-phosphate, O-diphosphate, O-triphosphate and O phosphonate, as well as its possible tautomers, its possible pharmaceutically acceptable addition salts with an acid or a base, and its N-oxide forms, for the preparation of a drug having antiviral activity against a Flaviviridae.

  • Publication number: 20060194217
    Abstract: The invention provides a method of preparation of HBV genomic amplicons which makes it possible, using the same amplicon obtained from a patient, to evaluate HBV strains resistant to antiviral agents by analysing, their genotype, their phenotype and their replicative capacity. The method of the invention guarantees to obtain the closest in vitro replication capability compared to the in vivo replication and ensures that the influences of all the mutations present on a viral genome are taken into account when evaluating the drug sensitivity and the replicative capacity.
