Definitions

  • the present invention relates to a method of treating Alzheimers disease and to the use of compounds in the preparation of a medicament for the treatment of Alzheimers disease.
  • US Patent No. 5,192, 753 states inter alia that dementia in human beings may be treated with compounds selected from the non-steroidal anti-inflammatory group of cyclooxygenase inhibitors.
  • the non-steroid anti-inflammatory drugs (NSAIDs) referred to in US Patent No. 5,192,753 are all agents which possess significant ability to inhibit cyclooxygenase type 1 (COX-1).
  • NSAIDs non-steroid anti-inflammatory drugs
  • COX-1 cyclooxygenase type 1
  • COX Cyclooxygenase
  • the present invention provides a method of treating a neurodegenerative disease and in particular Alzheimers disease which comprises administering to a human in need thereof a therapeutically effective amount of a non-steroid COX-II inhibitor. From antoher aspect this invention provides the use of a COX-II inhibitor in the manufacture of a medicament for the treatment of a neurodegenerative disease and in particular Alzheimers disease.
  • treating includes treatment of existing disease and prophylactic treatment of those at risk of developing the disease.
  • COX-II inhibitor means a compound able to inhibit human COX-II enzyme without causing relatively significant inhibition of human COX-I enzyme.
  • compounds which bind at least 10 times as well to COX-I receptors as to COX-II receptors are chosen for use in the invention, more aptly 20 times as well, favourably 50 times as well most favourably at least 100 times as well, and preferably at least 1000 times as well
  • the COX-II inhibitors for use in this invention are most aptly those which are highly brain penetrant so that the maximum concentration of COX-II inhibitor after administration of the anti-neurodegenerative for example the anti-alzheimer effective dose of COX-II inhibitor is at least the binding IC50 value and preferably at least 10 times that value for example at least 100 times the binding IC50 value.
  • the COX-II inhibitor may be of any structural type other than a steroid. However, most aptly the COX-II inhibitor employed in this invention is not a carboxylic acid or a salt thereof. Most favourably it will possess a S0 2 CH 3 , NHS0 2 CH 3 , S0 2 NH 2 , S0 2 NHCH 3 or like substituent on an aromatic ring especially on a phenyl ring. * o -
