  • Publication number: 20230105935
    Abstract: Provided herein are antiviral compounds having the structure of Formula (I) and compositions thereof for use in the treatment of viral infection. In particular, the compounds of Formula (I) are capable of interfering with the export of viral mRNA processing as reflected in the altered accumulation of viral RNA isoforms as well as transport from the nucleus to the cytoplasm. Such compounds show a reduction of HIV, adenovirus and coronavirus infection of cells. The invention provides compounds that may be suitable for the treatment of HIV/AIDS.

  • 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: 8546346
    Abstract: The present invention relates to a method of modulating splice site selection, splicing and alternative, the method comprising the step of hybridizing an oligonucleotide-protein conjugate to a target pre-mRNA molecule in a cell or cell extract, wherein the oligonucleotide-protein conjugate comprises an oligonucleotide moiety which comprises at least two distinct sequence elements: (i) a nucleic acid sequence that is complementary to a specific region upstream of the splice site in the target pre-mRNA molecule; and (ii) an extension containing a protein binding site sequence element for covalently binding a protein; wherein the protein moiety comprises a protein capable of modulating splicing of the splice site upon binding with the protein binding site.

  • Publication number: 20040048376
    Abstract: The present invention relates to splicing and especially to alternative RNA splicing which is involved in the production of protein isoforms with distinct activities. More specifically, the present invention relates to methods for modulating alternative splicing, and for identifying alternatively spliced units in genes. The present invention also concerns methods for modulating the ratio of alternatively spliced isoforms relative to each other and to normalize the alternative splicing actions of a splicing extract. The invention also relates to kits for normalizing and/or modulating splicing and/or alternative splicing of transcripts. More particularly the invention relates to a method to normalize a splicing and/or alternative splicing activity of an extract comprising an addition thereto of an effective amount of a polar aprotic solvent, whereby the effective amount normalizes splicing and/or alternative splicing as compared to an untreated extract.
