Definitions

  • the invention relates generally to pharmaceutically active compounds, pharmaceutical compositions and methods of use thereof, to treat Beta-Secretase mediated disorders, including Alzheimer's disease, plaque formation on the brain and related conditions.
  • AD Alzheimer's disease
  • AD is a disease that affects greater than 12 million aging people worldwide. AD accounts for the majority of dementia clinically diagnosed after the age of 60. AD is generally characterized by the progressive decline of memory, reasoning, judgement and orientation. As the disease progresses, motor, sensory, and vocal abilities are affected until there is global impairment of multiple cognitive functions. The loss of cognitive function occurs gradually, typically leading to a diminished cognition of self, family and friends. Patients with severe cognitive impairment and/or diagnosed as end-stage AD are generally bedridden, incontinent, and dependent on custodial care. The AD patient eventually dies in about nine to ten years, on average, after initial diagnosis. Due to the incapacitating, generally humiliating and ultimately fatal effects of AD, there is a need to effectively treat AD upon diagnosis.
  • AD Alzheimer's disease
  • A-beta beta- amyloid peptide
  • Amyloid containing plaques and vascular amyloid angiopathy were also found in the brains of individuals with Down's Syndrome, Herditary Cerebral Hemorrhage with Amyloidosis of the Dutch-type (HCHWA-D), and other neurodegenerative disorders.
  • A-Beta formation is a causative precursor or factor in the development of AD.
  • Deposition of A-beta in areas of the brain responsible for cognitive factors is a major factor in the development of AD.
  • Beta amyloid plaques are primarily composed of amyloid beta peptide (A-beta peptide).
  • A-beta peptide is derived from the proteolytic cleavage of a large transmembrane amyloid precursor protein (APP), and is a peptide ranging in about 39-42 amino acids.
  • APP transmembrane amyloid precursor protein
  • A-beta 42 (42 amino acids long) is thought to be the major component of these plaque deposits.
  • Beta secretase (BACE, also commonly referred to as memapsin) is thought to first cleave APP to generate two fragments of the A-beta peptide: (1) a first N-termin us fragment and (2) a second C-99 fragment, which is subsequently cleaved by gamma secretase to generate the C-terminus fragment of the A-beta peptide.
  • APP has also found to be cleaved by alpha-secretase to produce alpha-sAPP, a secreted form of APP that does not result in beta-amyloid plaque formation.
  • BACE is an aspartyl protease enzyme comprising 501 amino acids and responsible for processing APP at the beta-secretase specific cleavage site. BACE is present in two forms, BACE 1 and BACE 2, designated as such depending upon the specific cleavage site of APP. Beta secretase is described in Sinha et ah, Nature, 402:537- 554 (1999) (p510) and PCT application WO 2000/17369.
  • A- beta peptide accumulates as a result of APP processing by BACE. Moreoevr, in vivo processing of APP at the beta secretase cleavage site is thought to be a rate-limiting step in A-beta production. Sabbagh, M. et a ⁇ ., ⁇ lz. Dis. Rev. 3:1-19 (1997). Thus, inhibition of the BACE enzyme activity is desirable for the treatment of AD. Studies have shown that the inhibition of BACE may be linked to the treatment of AD. BACE 1 knockout mice fail to produce A-beta, and present a normal phenotype.
  • WO 03/050073 describes inhibitors of beta secretase, useful for treating AD and other beta-secretase mediated disorders.
  • the present invention provides a new class of compounds useful for the modulation of beta secretase and, to that end, useful for the regulation or reduction of the formation of A-beta peptide and consequently, the reduction of beta amyloid plaque formation on the brain. Accordingly, the compounds of the invention are useful for the treatment of Alzheimer's disease and other beta secretase mediated disorders.
  • the compounds provided by the invention including stereoisomers, tautomers, solvates, pharmaceutically acceptable salts, derivatives or prodrugs thereof, are defined by general Formula I
  • the compounds provided by the invention are capable of modulating beta secretase.
  • the invention further provides for the use of these compounds for therapeutic, prophylactic, acute and/or chronic treatment of beta secretase mediated diseases, such as those described herein.
  • the compounds are useful for the prophylaxis and treatment of AD and other diseases or conditions involving amyloid plaque formation on the brain.
  • the invention also provides pharmaceutical compositions, which comprise one or more compounds of the invention, methods for the treatment of beta secretase mediated diseases, such as AD, using the compounds and compositions of the invention, and intermediates and processes useful for the preparation of the compounds of the invention.
  • the invention also provides the preparation of a a pharmaceutical composition or of a medicament, containing one or more of the compounds, useful to attenuate, alleviate, or treat disorders through inhibition of beta secretase.
