NOVEL SULFONE AMIDE DERIVATIVES CAPABLE OF INHIBITING BACE

The present invention relates to novel derivatives of sulfone amide of Formula 1 as defined in this disclosure which inhibit the activity of BACE (or beta-secretase). These sulfone amide derivatives are useful for the treatment and prevention of Alzheimer's disease and related diseases caused by production of beta-amyloid, by inhibiting the activity of BACE.

Structure-based design: Potent inhibitors of human brain memapsin 2 (β-secretase)

Memapsin 2 (β-secretase) is one of two proteases that cleave the β-amyloid precursor protein (APP) to produce the 40-42 residue amyloid-β peptide (Aβ) in the human brain, a key event in the progression of Alzheimer's disease. On the basis of the X-ray crystal structure of our lead inhibitor (2, OM99-2 with eight residues) bound to memapsin, we have reduced the molecular weight and designed potent memapsin inhibitors. Structure-based design and preliminary structure-activity studies have been presented.
