- Table 1 which follows illustrates the chemical structures and the physical properties of some examples of compounds according to the invention. In this table :
- PF ( 0 C) represents the melting point of the compound in degrees Celsius
- R3 represents a trifluoromethyl group.
- the compounds according to the invention were the subject of pharmacological tests to determine their inhibitory effect vis-à-vis the ⁇ -secretase activity.
- the ⁇ -secretase activity measured corresponds to that of a purified recombinant form of the human BACE1 aspartyl protease (the latter comprising a C-terminal hexa-histidine tag) produced by expression in Drosophila cells.
- the purified enzyme is packaged in TRIS buffer (18 mM) at pH 7.5 containing NaCl (0.45M), MnCl 2 (0.9 mM), CaCl 2 (0.9 mM), alpha D methylmanoside, 10% glycerol, and stored at -80 ° C. until use.
- BACE activity 1 is measured from the cleavage of a fluorogenic peptide substrate, called FS1, originally described by Ermolieff et al. (2000, Biochemistry, 39, 12450-12456), and based on the principle of fluorescence resonance energy transfer (FRET); the cleavage of the FS1 peptide is measured according to the increase of the fluorescent signal emitted by the EDANS group (or 5 - [(2-aminoethyl) amino] -naphthalene-1-sulfonic acid).
