  • Ion channel-like polypeptide and use thereof
    Patent number: 7592424
    Abstract: A single polypeptide is disclosed that without the need of any direct ion flow, is capable of converting electrical signals to chemical signals. The polypeptide of at least one embodiment of the present invention can be a novel membrane protein including a specified domain capable of independently functioning as a potential sensor and another domain exhibiting a phosphatise activity. In one potential embodiment, the polypeptide preferably consists of the 1st to 239th amino acids of the amino sequence of SEQ ID NO. 2.
    Type: Grant
    Filed: May 13, 2005
    Date of Patent: September 22, 2009
    Assignees: Kyoto University, National Institutes of Natural Sciences
    Inventors: Noriyuki Satoh, Yasushi Okamura, Hirohide Iwasaki, Yoshimichi Murata

  • Intracellular calcium concentration increase inhibitors
    Patent number: 7217701
    Abstract: An intracellular calcium concentration increase inhibitor containing as the active ingredient (1) a boron compound represented by the formula (I). The compound represented by the formula (I) inhibits the increase of the intracellular calcium concentration, and therefore it is deemed to be useful as an agent for the prophylaxis and/or treatment of platelet aggregation, ischemic diseases in hearts and brains, immune deficiency diseases, allorgosis, bronchial asthma, hypertension, cerebrovascular spasm, various renal diseases, pancreatitis, Alzheimer's disease, etc.
