  • Patent number: 6916819
    Abstract: This invention relates to benzimidazoles, pyridylimidazoles and related bicyclic heteroaryl compounds, all of which may be described by of Formula I The invention is particularly related to such compounds that bind with high selectivity and high affinity to the benzodiazepine site of GABAA receptors. This invention also relates to pharmaceutical compositions comprising such compounds and to the use of such compounds in treatment of certain central nervous system (CNS) diseases. Novel processes for preparing compounds of Formula I are disclosed. This invention also relates to the use of benzimidazoles, pyridylimidazoles and related bicyclic heteroaryl compounds of Formula I in combination with one or more other CNS agents to potentiate the effects of the other CNS agents. Additionally this invention relates to the use such compounds as probes for the localization of GABAA receptors in tissue sections.

  • Patent number: 6468983
    Abstract: 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.

  • Patent number: 6214805
    Abstract: 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.

  • Patent number: 5998602
    Abstract: The invention concerns a compounds and methods for treating infection with Respiratory Syncytial Virus. The compounds comprise an antisense portion, which is complementary to a normally single stranded portion of the RSV antigenomic strand (the mRNA strand), a linker and a oligonucleotide activator of RNase L, a ubiquitous non-specific RNase. The method comprised forming a complex of an activated RNase L and the antisense molecule. The application teaches methods of determining which portions of the RSV antigenomic strand are normally single-stranded. The application teaches that an antisense oligonucleotide having the sequence of residues 8281-8299 of the RSV genome is particularly useful to practice the invention and provides in vitro results superior to those obtainable with the conventional drug of choice, ribavirin.
