  • Patent number: 7208466
    Abstract: The present invention relates to the treatment of pain and to compounds that modulate C-fibre activity. In particular, the present invention relates to the use of a lectin in the manufacture of a medicament for modulation of C-fibre neuron activity, and to lectin conjugates. The lectin conjugates comprise a lectin coupled to a peptide or protein, wherein the peptide or protein is substantially free of Clostridial neurotoxin enzyme activity. The present invention also concerns methods for manufacturing conjugates. The compounds and compositions described have particular application in the treatment of diseases of which C-fibre activity is a component. Such diseases include pain, inflamation, psoriasis and other C-fibre related conditions.

  • Patent number: 7193066
    Abstract: Toxin derivatives are prepared by proteolytic treatment of holotoxin, and their toxicity is reduced by contacting the preparation with a ligand, which can be a metal or an antibody or another ligand. This ligand selectively binds to the toxin but not to the toxin derivative. Removing the ligand and toxin bound to the ligand further reduces toxicity. A second ligand is used to remove conjugates of the toxin and the first ligand. Compositions contain the purified derivative, optionally plus the toxin and the ligand.

  • Patent number: 7192596
    Abstract: A single polypeptide is provided which comprises first and second domains. The first domain enables the polypeptide to cleave one or more vesicle or plasma-membrane associated proteins essential to exocytosis, and the second domain enables the polypeptide to be translocated into a target cell or increases the solubility of the polypeptide, or both. The polypeptide thus combines useful properties of a clostridial toxin, such as a botulinum or tetanus toxin, without the toxicity associated with the natural molecule. The polypeptide can also contain a third domain that targets it to a specific cell, rendering the polypeptide useful in inhibition of exocytosis in target cells. Fusion proteins comprising the polypeptide, nucleic acids encoding the polypeptide and methods of making the polypeptide are also provided. Controlled activation of the polypeptide is possible and the polypeptide can be incorporated into vaccines and toxin assays.

  • Patent number: 6962703
    Abstract: The invention relates to an agent specific for peripheral sensory afferents. The agent may inhibit the transmission of signals between a primary sensory afferent and a projection neutron by controlling the release of at least one neurotransmitter or neuromodulator from the primary sensory afferent. The agent may be used in or as a pharmaceutical for the treatment of pain, particularly chronic pain.

  • Publication number: 20040071736
    Abstract: A method of treating mucus hypersecretion, the causative factor in chronic obstructive pulmonary disease (COPD), asthma and other clinical conditions involving COPD, comprises administering a compound that inhibits exocytosis in mucus secreting cells or neurones that control or direct mucus secretion. Also described is a compound, for use in the treatment of hypersecretion of mucus, which inhibits mucus secretion by inhibiting mucus secretion by mucus secreting cells, and/or inhibiting neurotransmitter release from neuronal cells controlling or directing mucus secretion.

  • Publication number: 20030180289
    Abstract: A method of treatment of disease by inhibition of cellular secretory processes is provided. The method has particular application in the treatment of diseases dependent upon the exocytotic activity of endocrine cells, exocrine cells, inflammatory cells, cells of the immune system, cells of the cardiovascular system, and bone cells. Agents and compositions therefor, as well as methods for manufacturing these agents and compositions, are provided. In a preferred embodiment a clostridial neurotoxin, substantially devoid of holotoxin binding affinity for neuronal cells of the presynaptic muscular junction, is associated with a targeting moiety. The targeting moiety is selected such that the clostridial toxin conjugate so formed may be directed to a non-neuronal target cell to which the conjugate may bind. Following binding, a neurotoxin component of the conjugate, which is capable of inhibition of cellular secretion, passes into the cytosol of the target cell by cellular internalisation mechanisms.
