  • Publication number: 20170128483
    Abstract: The present invention relates to inhibitor(s) or antagonist(s) of PADI4 (peptidyl arginine deiminase, type IV), PPAR? (peroxisome proliferator-activated receptor delta), GCKR (glucokinase regulatory protein), and/or P2X4R (purinergic receptor P2X, ligand-gated ion channel 4) for the use as anti-viral agent(s) as well as for the use in the prevention and/or treatment of infection(s) with virus(es) of the Flaviviridae family, such as Dengue virus and hepatitis C virus (HCV). The present invention further relates to pharmaceutical compositions or kits comprising said inhibitor(s)/antagonist(s) and methods of preventing and/or treating infection(s) with virus(es) of the Flaviviridae family. The present invention further relates to methods of screening for antiviral agent(s).

  • Patent number: 9175269
    Abstract: The present invention provides modified hepatitis C virus genomic RNA, comprising nucleotide sequences of genomic RNA portions of two or more types of hepatitis C viruses, which comprises a 5? untranslated region, a core protein coding sequence, an E1 protein coding sequence, a p7 protein coding sequence, an E2 protein coding sequence, an NS2 protein coding sequence, an NS3 protein coding sequence, an NS4A protein coding sequence, an NS4B protein coding sequence, an NS5A protein coding sequence, an NS5B protein coding sequence, and a 3? untranslated region, and which can be autonomously replicated. In particular, the present invention relates to modified hepatitis C virus genomic RNA, which can be autonomously replicated by substitution of the RNA sequence portion encoding NS3, NS4, NS5A, and NS5B proteins of hepatitis C virus genomic RNA with a partial RNA sequence encoding NS3, NS4, NS5A, and NS5B proteins of a JFH1 strain shown in SEQ ID NO: 1.

  • Publication number: 20130209403
    Abstract: The invention relates to Phospholipase A2 (hereinafter also referred to as PLA2) inhibitors for use in the treatment or prevention of flavivirus infection, in particular an infection with a flavivirus of the genus Flavi or the genus Hepaci. The invention also provides a pharmaceutical formulation for use in the treatment or prevention of an infection with a flavivirus of the genus Flavi or the genus Hepaci and a method of preventing or treating an infection with a flavivirus of the genus Flavi or the genus Hepaci.
