| 20110189771 | Novel Imino Sugar Derivatives Demonstrate Potent Antiviral Activity and Reducted Toxicity - Imino sugars, such as deoxynojirimycin (DNJ), are glucose analogues that selectively inhibit cellular α-glucosidase I and II (enzymes that process N-linked glycans in glycoprotein) and exhibit broad spectrum antiviral activities against many enveloped viruses. Previously we have reported a novel DNJ derivative, OSL-95II, with antiviral activity and reduced cytotoxicity. In order to develop imino sugars with more potent antiviral activity as well as improved toxicity profile, OSL-95II was modified by diversifying the nitrogen linked alkylated side chain. The antiviral activities were initially tested in bovine viral diarrhea virus (BVDV) infected MDBK cells, yielding several imino sugar derivatives with novel structure and superior antiviral activity and toxicity profile. Furthermore, these new compounds were shown to be active against Dengue virus (DV) and West Nile virus (WNV) infection in BHK cells where potent anti-DV activity having submicromolar EC50 values and SI of greater than 900. These compounds represent a new generation of iminio sugars and their analogues, having application in the clinical treatment of infection of DV and other members of flaviviridae. | 08-04-2011 |

This invention also provides new application of a TaqMan hydrolysis probe in asymmetric real time PCR and melting curve analysis. | 03-03-2011 |
| 20090010880 | 2-Amino-2,7-dideoxy-alpha-D-glycero-D-gluco-heptopyranosyl Inhibitors of Positive Sense Single-Stranded RNA Envelope Viruses - The present invention is directed to compounds, compositions and methods comprising the aminoglycoside moiety represented by Formula II for treating and preventing the spread of positive sense single-stranded RNA envelope viral infections. One embodiment of the present invention uses geneticin or its analogs, including 2-amino-2,7-dideoxy-alpha-D-glycero-D-gluco-heptopyranose, as the antiviral agent. The compounds, compositions and methods of the present invention are applicable to infections resulting from Hepatitis C virus, West Nile virus, Yellow Fever virus, Dengue virus, Bovine Viral Diarrhea virus, Equine Arteritis virus, and/or Sindbis virus. | 01-08-2009 |
