  • Patent number: 9080174
    Abstract: RNA interference (RNAi) agents and the use of the RNAi agents for treating hepatitis B infection in individuals, as well as pharmaceutical compositions containing the RNAi agents are provided. The RNAi agents, or constructs for expressing them are utilized to inhibit expression of at least one Hepatitis B virus (HBV) gene, wherein each agent comprises an effector sequence complementary to or substantially complementary to a predicted sequence transcribed from a target region. In some embodiments of the present invention, the agents have more than one effector sequence; wherein the multiple effectors may target the same region of an HBV gene, different (possibly overlapping) regions of the same gene and/or different HBV genes.

  • Patent number: 9045753
    Abstract: Provided is a double-chain siRNA molecule targeting a microphthalmia-associated transcription factor MITF coding gene. A sense strand of the siRNA molecule has a sequence of SEQ ID NO: 3 and an anti-sense strand has a sequence of SEQ ID NO: 4, and the anti-sense strand specifically binds to mRNA of the MITF coding gene, to degrade the mRNA, thereby reducing the synthesis of melanin. Further provided is an application of the siRNA molecule in freckle whitening cosmetics or the preparation of medicines for treatment of diseases related to melanin gene.

  • Publication number: 20130210894
    Abstract: This invention relates to the application of the highly conserved sequences of viral genome, especially from a highly conserved domain of enteroviral genome as templates to design target small ligand RNAs (sliRNAs). The resulting sliRNAs are therapeutically active ingredients in the treatment of the related diseases caused by pathological angiogenesis.

  • Publication number: 20120232126
    Abstract: This invention relates to interfering RNA (iRNA) molecules and their applications, especially multi-targets iRNA molecules and their applications. The said multi-targets iRNA molecules comprised of a sense strand annealed onto at least one antisense strand, each strand is at least 30 nucleotides in length, the sense or antisense strand has at least two segments, which can target at least two RNAs of different genes, or can target at least two portions of an RNA, and wherein the iRNA does not induce an interferon-response when transfected into a cell. The iRNA molecule can interfere with the translation procedure post-transcription, and the target gene is inhibited or blocked, the iRNA does not induce an interferon-response in vivo. The RNA molecules are the active ingredient in preparation of the drug which can regulate one or many genes function.
