Definitions

  • the present invention relates to a compound for inhibiting GSK-3beta activity, a method for the preparation thereof, and a pharmaceutical composition containing the compound as an active ingredient.
  • Glycogen synthase kinase-3 (GSK-3) is a proline-directed serine-threonine kinase that was initially identified as a protein which inactivates glycogen synthase through phosphorylation. Two isoforms have been identified, alpha (GSK-3alpha) and beta (GSK-3beta), which show a high degree of amino acid homology to each other. Previous studies have reported that the GSK-3beta is involved in energy metabolism, neural cell development, and body pattern formation (NPL 1).
  • Neurodegenerative naturopathies including Alzheimer disease, are characterized by abnormal hyperphosphorylation of the microtubule-associated protein tau at proline- directed serine/threonine phosphorylation sites (NPL X).
  • NPL X proline- directed serine/threonine phosphorylation sites
  • GSK-3beta has been identified as a prime candidate mediating aberrant tau phosphorylation at disease- associated sites (NPLs 3-6).
  • NPLs 3-6 disease- associated sites
  • GSK-3beta is a promising target for therapeutic intervention in neurodegenerative tauopathies including Alzheimer disease.
  • Lithium carbonate, lithium citrate and lithium chloride are commonly used for the treatment of various disorders like mania, depression and migraine, and also used as an "augmenting" agent to increase the benefits of other standard drugs used for unipolar depression.
  • Lithium is a GSK-3beta inhibitor, and therefore, GSK-3beta inhibition is a promising target for the treatment of various such disorders.
  • GSK-3 inhibitors are available for treatment of type 2 diabetes by reducing the activity of glucose synthase.
  • GSK-3beta inhibitors can be used for a broad spectrum of diseases such as Alzheimer disease, mania, depression, migraine and type 2 diabetes and there is a strong need to develop such inhibitors for the treatment and/or prevention of GSK-
