Definitions

  • This invention relates to novel lactams having drug and bio-affecting properties, their pharmaceutical compositions and methods of use. These novel compounds inhibit the processing of amyloid precursor protein and, more specifically, inhibit the production of A ⁇ -peptide, thereby acting to prevent the formation of neurological deposits of amyloid protein. More particularly, the present invention relates to the treatment of neurological disorders related to ⁇ -amyloid production such as Alzheimer's disease and Down's Syndrome.
  • AD Alzheimer's disease
  • AD is a degenerative brain disorder characterized clinically by progressive loss of memory, temporal and local orientation, cognition, reasoning, judgment and emotionally stability.
  • AD is a common cause of progressive dementia in humans and is one of the major causes of death in the United States.
  • AD has been observed in all races and ethnic groups worldwide, and is a major present and future health problem. No treatment that effectively prevents AD or reverses the clinical symptoms and underlying pathophysiology is currently available (for review, Dennis J. Selkoe; Cell Biology of the amyloid (beta) -protein precursor and the mechanism of Alzheimer's disease, Annu Rev Cell Biol, 1994, 10: 373- 403) .
  • a ⁇ is an internal polypeptide derived from a type 1 integral membrane protein, termed ⁇ amyloid precursor protein (APP) .
  • APP amyloid precursor protein
  • ⁇ APP is normally produced by many cells both in vivo and in cultured cells, derived from various animals and humans.
  • a ⁇ is derived from cleavage of ⁇ APP by as yet unknown enzyme (protease) system(s), collectively termed secretases.
  • proteolytic activities include ⁇ secretase (s) , generating the N-terminus of A ⁇ , ⁇ secretase (s) cleaving around the 16/17 peptide bond in A ⁇ , and ⁇ secretases, generating C-terminal A ⁇ fragments ending at position 38, 39, 40, 42, and 43 or generating C-terminal extended precursors which are subsequently truncated to the above polypeptides .
  • missense DNA mutations at position 717 in the 770 isoform of ⁇ APP can be found in effected members but not unaffected members of several families with a genetically determined (familiar) form of AD.
  • ⁇ APP mutations have been described in familiar forms of AD.
  • similar neuropathological changes have been observed in transgenic animals overexpressing mutant forms of human ⁇ APP.
  • individuals with Down's syndrome have an increased gene dosage of ⁇ APP and develop early-onset AD.
  • a ⁇ will prevent and reduce neurological degeneration, by controlling the formation of amyloid plaques, reducing neurotoxicity and, generally, mediating the pathology associated with A ⁇ production.
  • One method of treatment methods would therefore be based on drugs that inhibit the formation of A ⁇ in vivo. Methods of treatment could target the formation of A ⁇ through the enzymes involved in the proteolytic processing of ⁇ amyloid precursor protein. Compounds that inhibit ⁇ or ⁇ secretase activity, either directly or indirectly, could control the production of A ⁇ .
  • compounds that specifically target ⁇ secretases could control the production of A ⁇ . Such inhibition of ⁇ or ⁇ secretases could thereby reduce production of A ⁇ , which, thereby, could reduce or prevent the neurological disorders associated with A ⁇ protein.
  • the present invention discloses compounds of enhanced activity in inhibiting A ⁇ protein production.
  • One object of the present invention is to provide novel compounds which are useful as inhibitors of the production of A ⁇ protein or pharmaceutically acceptable salts or prodrugs thereof. It is another object of the present invention to provide pharmaceutical compositions comprising a pharmaceutically acceptable carrier and a therapeutically effective amount of at least one of the compounds of the present invention or a pharmaceutically acceptable salt or prodrug form thereof.
