Definitions

  • the present invention relates to the identification of substances or agents that modulate the activity of the transient receptor potential 6 ion channel, TRPC6, and the use of such substances in the treatment of inflammatory diseases, particularly those of the respiratory system.
  • a variety of cells are attracted into tissues during inflammation. These include various leukocytes, particularly inflammatory phagocytes such as neutrophilic and eosinophilic granulocytes and monocytes. Neutrophils have been associated with inflammation and tissue destruction in respiratory diseases such as chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema associated therewith, and adult respiratory distress syndrome (ARDS), inflammatory bowel diseases such as Crohn's disease and ulcerative colitis, and rheumatoid arthritis. Eosinophils have been associated with respiratory diseases such as asthma and allergic rhinitis.
  • COPD chronic obstructive pulmonary disease
  • ARDS adult respiratory distress syndrome
  • Eosinophils have been associated with respiratory diseases such as asthma and allergic rhinitis.
  • Critical steps in the action of leukocytes in inflammatory conditions include the migration of these cells into the tissues, e.g. into the airways in respiratory inflammations or to the joints in rheumatoid arthritis, cell activation and the release of a range of inflammatory mediators, leukotrienes, oxygen radicals, proteases.
  • Signals that are needed for leukocyte migration and activation are often communicated through receptors that respond to an increase in the level of cytosolic calcium. Ins(l,4,5)P3 receptors are known to release calcium ions from intracellular stores but less is known about the channels in the plasma membrane through which those ions pass.
  • TRPC human omologue
  • TRPC6 has been found to be present in cells attracted into tissues during inflammation.
  • TRPC6 mRNA has been shown to be present in isolated primary human neutrophils and in human lung macrophages isolated by bronchoalveolar lavages from smokers and COPD patients.
  • TRPC6 mRNA expression has also been found in cultured human airway smooth muscle cells and well-differentiated human bronchial epithelial cells.
  • TRPC6 proteins have been shown to be expressed in human T-lymphocytes, cultured human airway smooth muscle cells, well-differentiated human bronchial epithelial cells, bronchial airway smooth muscle, epithelial cells of the airway epithelium, submucosal glands and tissue leukocytes i.e. neutrophils, macrophages and lymphocytes.
  • TRPC6 as a therapeutic target for such diseases and a "screening assay" for identifying modulators i.e., candidate compounds or agents including peptides, peptidomimetics, small molecules or other drugs, which stimulate or inhibit the activity of the channel formed by the gene product of human TRPC6.
  • the present invention relates to a method of identifying a substance suitable for use in the treatment of a leukocyte-associated inflammatory disease which modulates the activity of a polypeptide encoded by the human transient receptor potential 6 gene (TRPC6), wherein the method comprises combining a candidate substance with said polypeptide and measuring the effect of the candidate substance on the activity of said polypeptide.
  • TRPC6 human transient receptor potential 6 gene
  • the present invention relates to a pharmaceutical composition
  • a pharmaceutical composition comprising a compound that inhibits the influx of calcium ions through a human TRPC6 ion channel and a pharmaceutically acceptable carrier.
  • the present invention relates to the use of an antibody which is immunoreactive with a polypeptide encoded by the human TRPC6 gene, an antisense oligonucleotide comprising a nucleotide sequence complementary to a polynucleotide comprising a nucleotide sequence encoding that polypeptide, or a polynucleotide probe comprising at least 15 consecutive nucleotides of that polynucleotide, in the preparation of a pharmaceutical that inhibits the accumulation of leukocytes in human tissue.
  • the present invention relates to the use of an antibody which is immunoreactive with a polypeptide encoded by the human TRPC6 gene, an antisense oligonucleotide comprising a nucleotide sequence complementary to a polynucleotide comprising a nucleotide sequence encoding that polypeptide, or a polynucleotide probe comprising at least 15 consecutive nucleotides of that polynucleotide, in the preparation of a pharmaceutical for the treatment of a leukocyte-associated inflammatory disease.
  • the present invention relates to the use of a TRPC6 inhibitor in the preparation of a pharmaceutical for the treatment of a leukocyte-associated inflammatory disease.
  • the present invention relates to a method of the present invention for identifying a substance suitable for use in the treatment of a leukocyte-associated inflammatory disease which modulates the activity of a polypeptide encoded by the human transient receptor potential 6 gene.
  • this method, or assay comprises combining a candidate substance with a polypeptide encoded by the transient receptor potential channel 6 gene and measuring the effect of the candidate substance on the activity of that polypeptide.
  • TRPC6 agonists e.g. the activity of a TRPC6 gene product, i.e. the polypeptide that forms the TRPC6 ion channel, may be measured, for example, by a cell-based method or screening assay that identifies compounds which have a stimulatory or inhibitory effect on the activity of the human TRPC6 channel, or by an appropriate reporter gene assay.
  • the abovementioned screening method may be carried out, for example, by preparing cells which express the TRPC6 polypeptide on their surfaces, e.g. insect, mammal or yeast cells and then incubating the resulting cells with the candidate substance to determine the enhancement or inhibition of a functional activity of the TRPC6 polypeptide.
  • the candidate substance is combined with cells that are stably transfected with TRPC6 and express a functional TRPC6 channel and membrane depolarisation is measured to indicate any TRPC6-mediated Na + influx.
  • a suitable test for any inhibition of the TRPC6 channel cells that express an endogenous G protein-coupled calcium mobilising receptor e.g. muscarinic acetylcholine receptor that can activate TRPC6 channels are used and a receptor agonist e.g. muscarinic acetylcholine receptor agonist is added to stimulate the TRPC6 channels.
  • the cells are treated with the candidate substance prior to addition of the receptor agonist. That should produce an increase in fluorescence, but the magnitude of the increase will be reduced if the candidate substance inhibits the TRPC6 channels. Any change in fluorescence can be measured using suitable equipment, for example a fluorescence imaging plate reader.
  • the present invention also relates to a pharmaceutical composition that comprises a compound that inhibits the influx of calcium ions through a TRPC6 channel, such as l-[b-[3- (4-methoxy-phenyl)propoxy]-4-methoxyphenethyl]-lH-imidazole-HCl, and a pharmaceutically acceptable carrier.
  • a compound that inhibits the influx of calcium ions through a TRPC6 channel such as l-[b-[3- (4-methoxy-phenyl)propoxy]-4-methoxyphenethyl]-lH-imidazole-HCl
  • a pharmaceutically acceptable carrier such as l-[b-[3- (4-methoxy-phenyl)propoxy]-4-methoxyphenethyl]-lH-imidazole-HCl
  • an antibody which is immunoreactive with the polypeptide encoded by the human TRPC6 gene herein a "human TRPC6 antibody”
  • an antisense oligonucleotide comprising a nucleotide sequence complementary to the polynucleotide comprising a nucleotide sequence encoding that polypeptide
  • the aforementioned human TRPC6 antibodies and antisense oligonucleotides may be used to treat leukocyte-associated inflammatory diseases.
  • Human TRPC6 agonists, human TRPC6 antagonists, human TRPC6 antibodies and human TRPC6 antisense oligonucleotides are hereinafter alternatively referred to collectively as " agents of the invention " .
  • Neutrophil-associated inflammatory diseases to which the present invention is applicable include neutrophil-associated inflammatory or obstructive airways diseases, particularly chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema, and adult (or acute) respiratory distress syndrome (ARDS), rheumatoid arthritis and inflammatory bowel diseases such as Crohn's disease and ulcerative colitis.
  • neutrophil-associated inflammatory or obstructive airways diseases particularly chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema, and adult (or acute) respiratory distress syndrome (ARDS), rheumatoid arthritis and inflammatory bowel diseases such as Crohn's disease and ulcerative colitis.
  • Eosinophil- associated inflammatory diseases to which the present invention is also applicable include eosinophil-associated inflammatory or obstructive airways diseases, particularly asthma and allergic rhinitis.
  • TRPC6 is present in many of the resident cells of the lung, for instance epithelial cells and airway smooth muscle cells, however TRPC6 is also present in smooth muscle in the pulmonary artery. TRPC6 is up-regulated in these smooth muscle cells when stimulated by platelet derived growth factor (PDGF). PDGF increases are associated with pulmonary hypertension and proliferation of artery smooth muscle cells. Inhibition of TRPC6 expression e.g. using antisense suppresses PDGF-stimulated pulmonary artery smooth muscle cell proliferation. Accordingly, pharmaceuticals that inhibit TRPC6 in smooth muscle in the pulmonary artery are useful in the treatment of pulmonary hypertension.
  • PDGF platelet derived growth factor
  • a human TRPC6 polypeptide can be isolated using any suitable conventional method. Since the sequence for the human TRPC6 gene is known, specific primers may be used as a convenient option. For example, (SEQ 01) 5'-gcaaatgaaagctttggacc-3' as the forward primer and (SEQ 02) 5'-atcgtaacattatagactccat-3' as the reverse primer gives a polymerase chain reaction (PCR) product of 300 base pairs.
  • PCR polymerase chain reaction
  • a human TRPC6 polynucleotide may be cDNA, genomic DNA or RNA and may be obtained using any suitable conventional method. For example it may be prepared from the nucleotides which it comprises by chemical synthesis, e.g. automated solid phase synthesis using known procedures and apparatus.
  • a human TRPC6 antibody may be a polyclonal or monoclonal antibody. Such antibodies may be prepared using conventional procedures. Methods for the production of polyclonal antibodies against purified antigen are well established (cf. Cooper and Paterson in Current Protocols in Molecular Biology, Ausubel et al. Eds., John Wiley and Sons Inc., Chapter 11). Human TRPC6 antibodies may be used to detect, or determine the level of expression of, human TRPC6 polypeptides, or to inhibit ligand/anti-ligand binding activities of human TRPC6 polypeptides.
  • a human TRPC6 antisense oligonucleotide may be DNA, an analogue of DNA such as a phosphorothioate or methylphosphonate analogue of DNA, RNA, an analogue of RNA, or a peptide nucleic acid (PNA).
  • the antisense oligonucleotide may be synthesised by conventional methods, for example using automated solid phase techniques. It may be used to inhibit the expression of the human TRPC6 gene, where this is desired.
  • a short interfering RNA siRNA
  • RNA interference inhibits gene expression and can therefore be used to explore gene function. This technique is described by S. M. Elbashir et al in Methods 26 (2002) 199-213.
  • a human TRPC6 polynucleotide probe comprises at least 15 contiguous nucleotides of the aforementioned polynucleotide or a complement thereof.
