An eight residue peptidomimetic, tight binding transition-state analog inhibitor of human brain memapsin 2 (K_i = 1.6 nM, recombinant memapsin 2; K_i = 9.58 nM, recombinant pro-memapsin 2). Also inhibits cathepsin D (K_i = 48 nM). This aspartyl protease inhibitor is designed from the template of the β-secretase site of Swedish β-amyloid precursor protein (APP) with Asp to Ala replacement; also includes a nonhydrolyzable hydroxyethylene isostere between Leu and Ala.
A peptidomimetic, highly potent, tight-binding transition-state analog inhibitor of human brain β-secretase (K_i = 1.6 nM, recombinant memapsin-2; K_i = 9.58 nM, recombinant pro-memapsin 2). Designed from the template of the β-secretase site of Swedish β-amyloid precursor protein (APP) with Asp to Ala replacement. Includes a nonhydrolyzable hydroxyethylene isostere between Leu and Ala. Also reported to inhibit cathepsin D at higher levels (K_i = 48 nM).

Product does not compete with ATP.
