  • ALPHA CONOTOXIN PEPTIDES WITH ANALGESIC PROPERTIES
    Publication number: 20090197810
    Abstract: This invention relates to novel ?-conotoxin-like peptides comprising the following amino acid sequence (SEQ ID NO:10): Xaa1-Cys-Cys-Ser-Xaa2-Xaa3-Xaa4-Cys-Xaa5-Xaa6-Xaa7-Xaa8-Xaa9-Xaa10-Xaa11-Cys-NH2 in which Xaa1 is Gly or Asp; Xaa3 is Pro, Hyp or Glu; each of Xaa2 to Xaa8 and Xaa11 is independently any amino acid; Xaa9 is Pro, Hyp or Glu; Xaa10 is Asp, Glu or ?-carboxyGlu; Xaa11 is optionally absent; and the C-terminus is optionally amidated, with the proviso that the peptide is not ?-conotoxin Ep1 or ?-conotoxin Im1. The peptides are useful in the treatment or prevention of pain, in recovery from nerve injury, and in the treatment of painful neurological conditions such as stroke.
    Type: Application
    Filed: March 24, 2008
    Publication date: August 6, 2009
    Inventors: Bruce Grayson LIVETT, Zeinab Khalil, Kenwyn Ronald Gayler, John Geoffrey Down, David William Sandall, David Anthony Keays
  • ?-conotoxin peptides with analgesic properties
    Patent number: 7348400
    Abstract: This invention relates to novel ?-conotoxin-like peptides comprising the following sequence of amino acids: Xaa1CCSXaa2Xaa3Xaa4CXaa5Xaa6Xaa7Xaa8Xaa9Xaa10Xaa11C—NH2 in which Xaa1 is G or D; Xaa3 is proline, hydroxyproline or glutamine; each of Xaa2 to Xaa8 and Xaa11 is independently any amino acid; Xaa9 is proline, hydroxyproline or glutamine; Xaa10 is aspartate, glutamate or ?-carboxyglutamate; Xaa11 is optionally absent; and the C-terminus is optionally amidated, with the proviso that the peptide is not ?-conotoxin Ep1 or ?-conotoxin Im1. The peptides are useful in the treatment or prevention of pain, in recovery from nerve injury, and in the treatment of painful neurological conditions such as stroke.
