Patent number: 8828962Abstract: No antiviral regimen has been consistently successful in treating H5N1 virus infection. We demonstrate that a group of highly effective siRNAs targeting different H5N1 viral genes shares a unique motif, GGAGU/ACUCC. We further demonstrate that the effectiveness of siRNAs containing this motif is not sequence specific. The results suggested that the structure of the unique motif is critical in determining the potency of siRNA-mediated protective effects against viral infection and this potent in vivo protection is associated with early productions of ?-defensin and IL-6 induced by the motif. Provided are methods and prophylactic and therapeutic agents useful against other viral infections in addition to the H5N1 influenza virus.Type: GrantFiled: December 12, 2011Date of Patent: September 9, 2014Assignee: Xiangxue Group (Hong Kong) Company LimitedInventors: Bojian Zheng, Hongyan Sui, Yongping Lin

Patent number: 8691781Abstract: The invention provides siRNA compositions that interfere with viral replication in respiratory viral infections, including respiratory syncytial virus and avian influenza A, including the H5N1 strain. The invention further provides uses of the siRNA compositions to inhibit expression of viral genes in respiratory virus-infected cells, and to uses in the treatment of respiratory virus infections in a subject. Generally the invention provides polynucleotide that includes a first nucleotide sequence of 15 to 30 bases that targets the genome of a respiratory syncytial virus or an influenza A virus, a complement thereof, a double stranded polynucleotide or a hairpin polynucleotide. Additionally the invention provides vectors, cells and pharmaceutical compositions containing siRNA sequences.Type: GrantFiled: November 4, 2005Date of Patent: April 8, 2014Assignee: Sirnaomics, Inc.Inventors: Qingquan Tang, Patrick Lu, Martin Woodle, Bojian Zheng

Publication number: 20090298797Abstract: Compositions and methods for treating one or more symptoms of influenza, preferably influenza due to infection with influenza A (H5N1) are provided. It has been discovered that administration of a combination of a neuraminidase inhibitor with two immunomodulators increases survivability in subjects 24, 48, or even 72 hours post infection compared to administration of the neuraminidase inhibitor alone. A preferred neuraminidase inhibitor is zanamivir. Preferred immunomodulators include, but are not limited to celecoxib and mesalazine. Another embodiment provides a method for treating influenza, preferably, influenza due to infection with avian influenza A (H5N1) by administering to subject infected with the influenza virus, an effective amount of a neuraminidase inhibitor to inhibit or reduce budding of the influenza virus from infected cells of the subject, and an effective amount of at least two immunomodulators effective to reduce or inhibit one or more symptoms of inflammation in the subject.Type: ApplicationFiled: May 20, 2009Publication date: December 3, 2009Inventors: Bojian Zheng, Kowk-Yung Yuen
