  • Patent number: 5674683
    Abstract: The present invention provides stem-loop and circular oligonucleotides each with at least one Watson-Crick binding (WC) domain and at least one corresponding Hoogsteen binding (H) domain separated from each other by linker domains. Each WC domain has sufficient complementarity to bind to one strand of a defined nucleic acid target by Watson-Crick base pairing in an anti-parallel orientation. Each corresponding H domain is capable of binding to the WC domain by Hoogsteen base pairing in an anti-parallel manner. The present invention also provides methods of making and using these oligonucleotides as well as kits and pharmaceutical compositions containing these oligonucleotides.

  • Patent number: 5665346
    Abstract: The present invention provides human interleukin-8 (IL-8) analogs that are modified in the Glu4 Leu5 Arg6 region, and have a core structure corresponding to the IL-8 (7-51) sequence are provided. These neutrophil binding analogs display altered IL-8 activities that can be exploited for therapeutic and other purposes. Such antagonists include those in which, for example, the Leu5 and/or Arg6 residues are replaced, and in which the Glu4 and/or Leu5 residues are deleted. Also provided are biologically active human interleukin-8 (IL-8) analogs comprising a core sequence that includes IL-8 (1-51), IL-8 (3-51) or IL-8 (4-51). The invention also provides pharmaceutical compositions containing the aforementioned analogs.
