  • Patent number: 9534040
    Abstract: Provided is an antiviral agent against animal viruses. The antiviral agent contains a protein or a nucleic acid sequence encoding the protein, as an active ingredient, the protein having binding ability and degrading ability to foreign nucleic acid chains invaded in an animal cell and that has no cytotoxicity to the animal cell itself. Also provided is an antiviral animal cell containing the protein according to the present invention, or the nucleic acid sequence encoding the protein. The antiviral agent and antiviral animal cell exhibit advantageous effects in that they selectively degrade foreign nucleic acid chains invaded in an animal cell and have no cytotoxicity to the animal cell, thus causing no death of the animal cell.

  • Patent number: 7276501
    Abstract: The present invention relates to 6-(4-substituted-anilino)pyrimidine derivatives useful as an antiviral agent, and more particularly novel 6-(4-substituted-anilino)pyrimidine derivatives having an excellent inhibitory effect on replication of Hepatitis C virus; HCV), represented by the following formula I: in which R represents a C1-C4 straight or branched alkoxycarbonyl group, heterocycliccarbonyl group or carboxyalkyl group; and pharmaceutically acceptable salts thereof, a preparation method thereof, and an antiviral pharmaceutical composition comprising the compound as an effective ingredient. The 6-(4-substituted-anilino)pyrimidine derivatives according to the present invention have an excellent inhibitory effect on replication of Hepatitis C virus (HCV) and thus can be advantageously used as a therapeutic or prophylactic agent of hepatitis C.
