  • Publication number: 20110189771
    Abstract: Imino sugars, such as deoxynojirimycin (DNJ), are glucose analogues that selectively inhibit cellular ?-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.

  • Publication number: 20110184019
    Abstract: Long chain N-alkyl amino and imino compounds, oxa-substituted derivatives thereof, and pharmaceutical compositions including such compounds are described. The long chain N-alkyl group is a C8-C16 alkyl group. The long chain N-alkyl compounds and oxa-substituted derivatives thereof can be used in the treatment of viral infections, in particular hepatitis B virus or hepatitis C virus, in a cell or an individual. For example, the long chain N-alkyl compounds or oxa-substituted derivatives thereof can be derived from piperidines, pyrrolidines, phenylamines, pyridines, pyrroles, or amino acids.

  • Publication number: 20100285469
    Abstract: A method for tumor screening using urine of a mammal, the method includes obtaining a total urine nucleic acid (e.g., DNA) from a urine sample of a mammal, extracting a high molecular weight urine nucleic acid (above 1000 bp) by contacting the total urine nucleic acid with an adsorbent in the presence of a buffer which promotes binding of the high molecular weight urine nucleic acid to the adsorbent, replacing the buffer which promotes binding of the high molecular weight urine nucleic acid with a buffer which promotes binding of the low molecular weight urine nucleic acid to the adsorbent, extracting the low molecular weight urine nucleic acid by contacting with the adsorbent, eluting the low molecular weight urine nucleic acid, and assaying the low molecular weight urine nucleic acid for a presence or absence of a gene sequence specific to a certain type of tumor.
