  • Patent number: 9168260
    Abstract: The present invention describes a unique antiviral screen system. The assay is based on quantitatively monitoring viral activation of host cell beta-interferon (IFN-?) gene expression in a HEK293-derived reporter cell line expressing a firefly luciferase gene under the control of a human IFN-? promoter. Unlike the traditional high throughput antiviral assays that measure either the reduction of viral components/yields or cytopathic effect, the readout of the reporter assay in the present invention is the virus-induced host cellular innate immune response. Hence, the assay allows for identification of compounds that inhibit virus infection. In addition, because induction of IFN is one of the most common attributes of viruses, the assay is applicable to all the viruses that are able to infect the reporter cell line and induce IFN-? expression.

  • Publication number: 20150265672
    Abstract: The present invention provides small molecule inhibitors of hepatitis B virus (HBV) covalently closed circular (ccc) DNA, which are useful as therapeutics in the management of chronic HBV. The compounds of the invention achieve epigenetic modification of the cccDNA, histone modification and histone deacetylase activity inhibition, thus modulating HBV cccDNA. The present invention further provides methods for modulating HBV cccDNA, for treating or preventing HBV in a subject, and for modulating cccDNA transcription of hepatitis B in a subject.
