  • RNase L activator-antisense complexes
    Publication number: 20030203356
    Abstract: The present invention relates to methods of targeting RNA and is particularly useful for 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 target RNA (e.g. a negative strand RNA virus) to specifically cleave the genomic or antigenomic RNA strand of the target RNA (e.g. the 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.

  • Catalytic composition for carbonylation including iridium and pyridine polymers
    Patent number: 6458995
    Abstract: An improvement to methanol carbonylation processes utilizing a homogeneous iridium catalyst system comprises adding a rate-promoting amount of an insoluble pyridine ring-containing polymer. Typically, polyvinylpyridine is added to the reactor in amounts of up to about 2 wt. percent.

    Assignee: Celanese International Corporation
    Inventors: Hung-Cheun Cheung, Elaine C. Sibrel, G. Paul Torrence
  • Rhodium/inorganic iodide catalyst system for methanol carbonylation process with improved impurity profile
    Patent number: 6323364
    Abstract: The method of the present invention provides an improvement upon prior art methanol carbonylation methods which substantially reduces the production of carbonyl impurities. The production of carbonyl impurities, particularly acetaldehyde, crotonaldehyde, and 2-ethyl crotonaldehyde, in methanol carbonylation reactions has been found to decrease by maintaining less than about 4.5 wt % methyl iodide in the reaction medium during the course of the reaction.

  • Method of cleaving specific strands of RNA and medical treatments thereby
    Patent number: 5677289
    Abstract: A method of using a chimeric molecule made up of an antisense oligonucleotide attached to a 2',5'-oligoadenylate molecule to specifically cleave a sense strand of RNA, wherein the antisense oligonucleotide of the chimeric molecule is hybridized to the sense strand of RNA in the presence of 2',5'-dependent RNase.
