  • Publication number: 20020108130
    Abstract: The present invention relates to methods for identifying nucleic acid molecules that localize in the extracellular space, and combining them with known drugs to ultimately enhance the efficacy of existing drugs by simply increasing drug targeting. Other embodiments apply methods whereby an existing drug first is combined with a random population of oligonucleotides, then the resulting chimeric molecules are subjected to iterative rounds of evolution to yield a population of chimeric molecules that is enriched in the species of chimeric molecules that are preferentially excluded from cells. The chimeric molecules of the present invention have superior targeting capabilities than the uncombined drugs.

  • Publication number: 20020103349
    Abstract: The present invention relates to methods of using oligonucleotides for increasing the efficacy of existing drugs. In some embodiments, oligonucleotides are selected from a random population for their ability to enter cells. Then the selected oligonucleotides are combined with existing drugs to form chimeric-drug oligonucleotide molecules that access cells more readily than the uncombined drugs. Alternatively, the oligonucleotides are combined with the existing drug, and the resulting chimeric molecules are selected for their ability to enter cells. The chimeric drug-olignucleotide molecules are designed to improve various pharmacological properties of existing drugs, including organ and tissue specificity, and drug targeting.

  • Publication number: 20020098493
    Abstract: The present invention relates to methods of using amino acid sequences for increasing the efficacy of existing drugs. In some embodiments, amino acid sequences are generated and combined with existing drugs to generate drug-amino acid sequence chimeric complexes that have superior pharmacological properties than the uncombined drugs. The chimeric complexes are designed to target only desired organs, without affecting other organs where the drug's activity is not desired, and to enhance drug bioavailability without losing the drugs' therapeutic properties.

  • Patent number: 6200753
    Abstract: A method for increasing the specificity of hybridization between a nucleic acid probe and a nucleic acid sequence to be detected, by addition of blocker molecules, which are complementary to the probe, raise of temperature in order to melt non-perfectly matched hybrids of probe and detected nucleic acid sequences, and lowering of the temperature again.

  • Patent number: 6057099
    Abstract: A method for detecting the presence of an assayed nucleic acid sequence in a sample is an essentially two stage-procedure. As illustrated, in a first stage the sample is reacted in a manner which gives rise to the production of a triggering oligonucleotide where the sample contains the assayed sequence. In the second stage, the reaction product is incubated under appropriate conditions with an amplification system whereby, in the presence of triggering oligonucleotide, a large amount of a nucleic acid product is obtained. The detection of this product thus indicates the presence of the assayed sequence in the sample.
