| 20080214471 | Method for inhibition of viral infection - The invention is directed to inhibiting viral morphogenesis and viral infection. In particular, it concerns effecting such inhibition by inhibiting the prenylation or post prenylation reactions of a viral or host protein. | 09-04-2008 |
| 20090083869 | METHODS AND COMPOSITIONS FOR IDENTIFYING AGENTS THAT INHIBIT AN NS4B-MEDIATED NEOPLASTIC CELLULAR PHENOTYPE OF HCV INFECTED CELLS - The disclosure provides methods and compositions for identifying agents that inhibit a neoplastic cellular phenotype mediated by the NS4B protein nucleotide binding motif (NBM) of hepatitis C virus (HCV). In general, the methods involve contacting a candidate agent with a mammalian cell expressing an NS4B NBM polypeptide of an HCV virus, wherein expression of the NS4B NBM polypeptide in the absence of candidate agent promotes a neoplastic cellular phenotype, and detecting the presence or absence of an effect of said candidate agent on NS4B-mediated promotion of a neoplastic cellular phenotype. The disclosed methods and compositions find use in a variety of therapeutic and screening applications. | 03-26-2009 |
| 20100015093 | Methods and compositions of treating a flaviviridae family viral infection - Briefly described, embodiments of this disclosure include compounds, pharmaceutical compositions, methods of treating a host infected with a virus from the Flaviviridae family of viruses, methods of inhibiting HCV replication in a host, methods of inhibiting the binding of NS4B polypeptide to the 3′UTR of HCV negative strand RNA in a host, methods of treating liver fibrosis in a host, and the like. | 01-21-2010 |
| 20100028299 | Methods and compositions of treating a flaviviridae family viral infection - Briefly described, embodiments of this disclosure include compounds, pharmaceutical compositions, methods of treating a host infected with a virus from the Flaviviridae family of viruses, methods of inhibiting HCV replication in a host, methods of inhibiting the binding of NS4B polypeptide to the 3′UTR of HCV negative strand RNA in a host, methods of treating liver fibrosis in a host, and the like. | 02-04-2010 |
| 20100203498 | METHODS AND COMPOSITIONS FOR IDENTIFYING ANTI-HCV AGENTS - The invention provides methods and compositions for identifying agents for treating infection by viruses that encode a nucleotide-binding NS4B protein, or functional equivalent thereof, e.g., hepatitis C virus (HCV) or other members of the family Flaviviridae. In general, the methods involve contacting an NS4B nucleotide binding motif (NBM)-containing polypeptide with a candidate agent, and determining the effect of the candidate agent on nucleotide binding activity, a nucleotide hydrolyzing activity, or a nucleotide-dependent RNA binding activity of the polypeptide. A candidate agent that inhibits NS4B polypeptide binding to a nucleotide is an anti-viral agent, e.g., an anti-HCV agent. The invention also features a polynucleotide encoding a NS4B polypeptide having a modified NBM (e.g., which is impaired in NTP binding). The subject methods and compositions find use in a variety of therapeutic and screening applications. | 08-12-2010 |
| 20100260717 | METHODS OF TREATING A FLAVIVIRIDAE FAMILY VIRAL INFECTION, COMPOSITIONS FOR TREATING A FLAVIVIRIDAE FAMILY VIRAL INFECTION, AND SCREENING ASSAYS FOR IDENTIFYING COMPOSITIONS FOR TREATING A FLAVIVIRIDAE FAMILY VIRAL INFECTION - Briefly described, embodiments of this disclosure include compositions, pharmaceutical compositions, methods of treating a host infected with a virus from the Flaviviridae family of viruses, methods of identifying a candidate agent for the treatment of hepatitis C virus (HCV) infection, and the like. | 10-14-2010 |
| 20110052536 | METHODS OF TREATING A FLAVIVIRIDAE FAMILY VIRAL INFECTION AND COMPOSITIONS FOR TREATING A FLAVIVIRIDAE FAMILY VIRAL INFECTION - Briefly described, embodiments of this disclosure include compositions, pharmaceutical compositions, methods of treating a host infected with a virus from the Flaviviridae family of viruses, methods of treating HCV replication in a host, methods of inhibiting the binding of NS4B polypeptide to the 3′UTR of HCV negative strand RNA in a host, methods of treating liver fibrosis in a host, and the like. | 03-03-2011 |
| 20110217265 | Screening for Inhibitors of HCV Amphipathic Helix (AH) Function - Screening methods are provided for identifying pharmacologic inhibitors of HCV amphipathic helix (AH) function, which inhibitors are useful in the prevention and treatment of HCV infection. Also provided are compounds useful in the inhibition of viral replication. The methods of the invention are based on the unexpected discovery that the presence of an AH, e.g. an AH of an HCV polypeptide, causes an increase in the apparent diameter of the vesicles. The methods of the invention provide for addition of AH peptides to lipid vesicles, for example in a high-throughput format; which addition may be performed in the absence or presence of a candidate pharmacologic agent. The change in apparent vesicle size is measured, and compared to control samples. An increase in vesicle size or aggregation is indicative of AH function being present; and a lack of increase is indicative that the AH function is absent or has been inhibited by a test agent. | 09-08-2011 |
