Definitions

  • This invention relates to novel compounds which potentiate the AMPA receptor.
  • the invention also relates to the use of the compounds in treating diseases and conditions mediated by potentiation of the AMPA receptor, compositions containing the derivatives and processes for their preparation.
  • Glutamate receptors which mediate the majority of fast excitatory neurotransmission in the mammalian central nervous system (CNS), are activated by the excitatory amino acid, L-glutamate (for review see Watkins JC, Krogsgaard-Larsen P, Honore T (1990) Trends Pharmacol Sci 11 : 25-33).
  • Glutamate receptors can be divided into two distinct families.
  • the G-protein or second messenger-linked "metabotropic" glutamate receptor family which can be subdivided into three groups (Group I, mGlui and mGlu5; Group II, mGlu2 and mGlu3; Group III, mGlu4, mGlu ⁇ , mGlu7, mGlu ⁇ ) based on sequence homology and intracellular transduction mechanisms (for review see Conn PJ and Pinn JP (1997) Ann Rev Pharmacol Toxicol 37: 205-237).
  • the "ionotropic" glutamate receptor family which directly couple to ligand-gated cation channels, can be subdivided into at least three subtypes based on depolarizing activation by selective agonists, N-methyl-D-aspartate (NMDA), ⁇ -amino-3-hydroxy-5- methylisoxazole-4-propionic acid (AMPA) and kainic acid (KA) (for review see Dingledine R, Borges K, Bowie, Traynelis S (1999) 51 : 7-61 ).
  • NMDA N-methyl-D-aspartate
  • AMPA ⁇ -amino-3-hydroxy-5- methylisoxazole-4-propionic acid
  • KA kainic acid
  • AMPA receptors exist as heterotetramers consisting of combinations of four different protein subunits (GIuRI -4) (for review see Bettler B and Muller C (1995) 34:
  • Receptor subunit diversity is increased further as each subunit can undergo alternative splicing of a 38 amino acid sequence in the extracellular region just before the fourth membrane spanning domain M4.
  • Such editing results in so-called 'flip' and 'flop' receptor isoforms which differ in kinetic and pharmacological properties (Sommer B, Keinanen K, Verdoon TA, Wisden W, Burnashev N, Herb A, Kohler M, Takagi T,
  • GluR2 mRNA changes a neutral glutamine to a positively charged arginine within M2.
  • GluR2 is edited in this way.
  • AMPAR containing such edited GluR2 subunit exhibit low calcium permeability (Burnachev N, Monyer H, Seeburg PH, Sakmann B (1992) Neuron 8: 189-198).
  • the number of AMPAR with high calcium permeability is elevated in certain disease-associated conditions (Weiss JH, and Sensi SL (2000) Trends in Neurosci 23: 365-371 ).
  • LTP Long Term Potentiation
  • AMPAR positive allosteric modulators do not activate the receptor directly.
  • AMPAR modulators increase receptor activity.
  • AMPA receptor modulators enhance synaptic function when glutamate is released and is able to bind at post-synaptic receptor sites.
  • Such compounds also enhance the learning and performance of various cognitive tasks in rodent (Zivkovic I, Thompson DM, Bertolino M, Uzunov D, DiBeIIa M, Costa E, Guidotti A (1995) JPET 272: 300-309, Lebrun C, Pilliere E, Lestage P (2000) Eu J Pharmacol 401 : 205-212), sub-human primate (Thompson DM, Guidotti A, DiBeIIa M, Costa E (1995) Proc Natl Acad Sci 92: 7667-7671 ) and man (Ingvar M, Ambros-lngerson J, Davis M, Granger R, Kessler M, Rogers GA, Schehr RS, Lynch G (1997) Exp Neurol 146: 553-559).
