  • Patent number: 5637573
    Abstract: A method of inhibiting influenza virus replication through the activity of natural (unmodified) or modified oligonucleotides (oligodeoxynucleotides or oligoribonucleotides) which hybridize to a selected region of the influenza virus RNA and interfere with its ability to serve as a template for synthesis of encoded products. Oligonucleotides (unmodified or modified) which have antiviral activity against influenza virus as a result of their ability to hybridze to a selected region of influenza virus RNA and inhibit its ability to serve as a template for synthesis of encoded products, as well as compositions which include the oligonucleotides.

    Assignee: Worcester Foundation for Biomedical Research, Inc.
    Inventors: Eliezer Rapaport, Paul C. Zamecnik
  • Patent number: 5559221
    Abstract: A method of purifying full length synthetic target oligonucleotides from a mixture of oligonucleotides, particularly from a mixture containing truncated or failed sequences. The method involves attaching a short nucleotide sequence complementary to the 5' end of a target oligonucleotide to a solid support. The complementary between the most 5' nucleotides of the target oligonucleotide and the bound oligonucleotide results in hybridization which serves to retain the target oligonucleotide. Truncated or failed sequences lacking 5' sequences complementary to the attached oligonucleotide, fail to hybridize and therefore are not retained. The method makes it possible to purify gram quantities of synthetic deoxyribonucleic acids or ribonucleic acids and sequences which have modifications, such as on the phosphate backbone. The support-bound nucleotide sequences are stable under conditions of purification and therefore can be reused.
