  • Patent number: 9474759
    Abstract: Antiviral protease inhibitors, including peptidyl aldehydes, peptidyl ?-ketoamides, peptidyl bisulfate salts, and peptidyl heterocycles, are disclosed, along with related antiviral compounds, and methods of using the same to treat or prevent viral infection and disease. The compounds possess broad-spectrum activity against viruses that belong to the picornavirus-like supercluster, which include important human and animal pathogens including noroviruses, enteroviruses, poliovirus, foot-and-mouth disease virus, hepatitis A virus, human rhinovirus (cause of common cold), human coronavirus (another cause of common cold), transmissible gastroenteritis virus, murine hepatitis virus, feline infectious peritonitis virus, and severe acute respiratory syndrome coronavirus.
    Type: Grant
    Filed: September 27, 2012
    Date of Patent: October 25, 2016

  • Patent number: 6805867
    Abstract: The present invention provides the genes encoding the following BRV proteins: for group A, the VP4 and VP7 proteins of the Indiana (IND) strain, and the VP7 protein of the 2292B strain; for group B, the VP7 protein of the WD653 strain; for group C, the VP4 and VP7 proteins of the Shintoku strain. The genes are useful for producing nucleic acid probes which are complementary to the VP7 and VP4 genes. Such probes are useful for detecting the presence of group A,B, and C BRV in fecal samples from diarrheic calves and for determining the serotype of the BRV field isolates. The genes are also useful for producing partial length nucleic acid probes which are complementary to hypervariable regions of the VP4 and VP7 genes. The present invention also relates to partially purified VP2, VP4, VP6 and VP7 proteins of the IND strain and VP4 and VP7 of the 2292B strain, the partially purified VP7 protein of the WD653 strain, and partially purified VP2, VP4 and VP7 proteins of the Shintoku strain.

  • Patent number: 4341870
    Abstract: This invention relates to a precursor or intermediate for a rotavirus vaccine to protect infants and young children against diarrhea caused by rotavirus. The invention is the efficient propagation of a strain of human rotavirus type 2 prepared by a method of cultivation by multiple passages in vivo in gnotobiotic piglets and by multiple passages in vitro subsequently in AGMK (African green monkey kidney) cell cultures. Additionally, rotavirus is treated with a biologically active amount of trypsin prior to growth in AGMK cells, and the inoculated cell cultures are centrifuged at a low centrifugal force before incubation.
