Patents by Inventor David James Craik

David James Craik has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8354372
    Abstract: This invention relates to an oral or enteral pharmaceutical preparation comprising at least one synthetically cyclised alpha-conotoxin peptide having an amide cyclised backbone such that the peptide has no free N- or C-terminus, said peptide having the ability to inhibit a nicotinic acetylcholine receptor and comprising four cysteine residues bonded in pairs to form two disulfide bonds, wherein the N-terminus of the corresponding linear/non-cyclised conotoxin peptide is linked to the C-terminus by a peptide linker, in a vehicle which is pharmaceutically suitable for oral or enteral administration.
    Type: Grant

    Assignee: The University of Queensland
    Inventors: Richard Clark, David James Craik
  • Patent number: 8242250
    Abstract: The present invention relates to a novel nucleic acid molecule encoding an amino acid sequence, which is capable of forming a cyclic structure. Cyclization may occur within a cell or cell membrane, or linear forms of the molecules may be circularised or partially circularised, in vitro using isolated enzyme systems or chemical means. The cyclised amino acid sequence is generally in the form of a stabilized folded structure such as acyclic knotted peptide, polypeptide or protein or functional equivalent. The nucleic acid molecules and cyclic and linear peptides are useful inter alia in the generation of molecules having animal or plant therapeutic properties, as well as in a range of diagnostic, industrial and agricultural, including horticultural, applications. Of particular importance is the use of these molecules in the protection of plants, such as crop plants, from pest and/or pathogen infestation.

  • Publication number: 20110244564
    Abstract: The present invention relates generally to a molecular framework having a cyclic structure. More particularly, the present invention provides cyclic proteins and derivatives thereof in which particular turns and other elements of the molecular structure are held in defined orientations with respect to each other. The cyclic proteins of the present invention provide a molecular framework for the introduction of particular amino acids or heterologous amino acid sequences to facilitate the presentation of biological activities associated with these heterologous amino acid sequences. The molecular framework of the present invention may be naturally cyclic or may be a cyclized derivative of a linear molecular or may be a linear derivative of a cyclized molecule. The present invention contemplates the use of the molecular framework with or without particular ammo acids inserted or substituted thereon for the treatment of or prophylaxis of disease conditions in animals, mammals (including humans) and plants.
