    摘要: The present invention relates to chimeric molecules comprising an oligonucleotide complementary to a region of the ribonucleotide component of telomerase attached to an activator of RNase L (“activator-antisense complex”) which specifically cleaves the ribonucleotide portion of a telomerase enzyme. The present invention relates to methods of inhibiting telomerase enzymatic activity with activator-antisense complexes targeted to the RNA component of telomerase. The present invention further relates to methods of treating malignant neoplastic disease, wherein the malignant cells contain a telomerase activity that is necessary for the growth of the malignant cells.

    摘要: The present invention relates to methods of inhibiting infection by RNA viruses with complexes of an activator of RNase L and an oligonucleotide that is capable of binding to the genome, antigenome or mRNAs of a negative strand RNA virus to specifically cleave the genomic or antigenomic RNA strand of the virus. In accordance with the present invention, the methods and complexes of the invention may be applied to target any negative strand RNA virus. The invention in one embodiment relates to a covalently linked complex of an oligonucleotide that is capable of binding to the genomic or antigenomic template RNA strand of a negative strand RNA virus and/or binding to an mRNA of a viral protein (an “antisense oligonucleotide”) coupled to an activator of RNase L. In a preferred embodiment of the present invention, the oligonucleotide component of the complex is complementary to a region of the viral genomic RNA strand characterized by repeated or consensus sequences.
