Patent number: 5861501Abstract: A method is provided for making synthetic capped RNAs. These compounds serve as substrates for the virally encoded endonuclease associated with influenza virus. We are able to assay for this unique and specific viral activity of cleavage of a capped RNA in vitro. Therefore, screening of inhibitors of this activity is possible. In addition, short non-extendible (due to their length or because of the modification of the 3'-end of the oligo, i.e. 3'-dA) RNAs are potent inhibitors of the cleavage of capped RNAs by influenza endonuclease. Finally, these compounds may be used to investigate viral and cellular mechanisms of transcription/translation or mRNA maturation.Type: GrantFiled: February 4, 1997Date of Patent: January 19, 1999Assignee: Merck & Co., Inc.Inventors: Fritz Benseler, James L.

Patent number: 5736524Abstract: Genes encoding Mycobacterium tuberculosis (M.tb) proteins were cloned into eukaryotic expression vectors to express the encoded proteins in mammalian muscle cells in vivo. Animals were immunized by injection of these DNA constructs, termed polynucleotide vaccines or PNV, into their muscles. Immune antisera was produced against M.tb antigens. Specific T-cell responses were detected in spleen cells of vaccinated mice and the profile of cytokine secretion in response to antigen 85 was indicative of a T.sub.h 1 type of helper T-cell response (i.e., high IL-2 and IFN-.gamma.). Protective efficacy of an M.tb DNA vaccine was demonstrated in mice after challenge with M. bovis BCG, as measured by a reduction in mycobacterial multiplication in the spleens and lungs of M.tb DNA-vaccinated mice compared to control DNA-vaccinated mice or primary infection in naive mice.Type: GrantFiled: November 14, 1994Date of Patent: April 7, 1998Assignees: Merck & Co.,.
