TECHNICAL FIELD
This invention relates to a compound having an inhibitory activity against production of amyloid β protein and useful for treating diseases induced by production, secretion and/or deposition of amyloid β protein.
BACKGROUND ART
In the brain of Alzheimer's patient many insoluble spots (senile plaque) are found, which is formed by extraneuronal accumulation of a peptide called amyloid β protein comprised of about 40 amino acids. Neuronal death caused by the senile plaque is considered to develop Alzheimer's Disease and an enhancer of amyloid β protein decomposition or vaccine of amyloid β protein etc. are extensively studied as a remedy for Alzheimer's Disease.
Secretase is an enzyme producing amyloid β protein by intracellular cleavage of a protein called amyloid β protein precursor (APP). An enzyme playing a role for producing an N-terminal of the amyloid β protein is called BACE1 (beta-site APP-cleaving enzyme) and an inhibitor of the BACE1, which will reduce production of amyloid β protein, could be a remedy for treating Alzheimers disease.
Patent literature 1 discloses a compound with a chemical structure similar to that of the compound of the present invention, having an inhibitory activity of NO synthetase and effective for treating dementia.
Patent literature 2-5 and non-patent literature 1-2 disclose compounds with a chemical structure similar to those of the compound of the present invention, and describe that each compound is useful as an anti-hypotensive agent, morphine-like analgesic or tranquilizer, intermediate of a therapeutic agent. NPYY5 antagonist, analgesic and the like.
Patent literatures 6-14 disclose BACE-1 inhibitors having a chemical structure different from that of the compound of the present invention. Also, patent literature 15 discloses a BACE-1 inhibitor,

Compounds of the present invention are useful for treating diseases induced by production, secretion or deposition of amyloid β protein, and effective for the treatment and/or prophylaxis, or improvement of conditions for Alzheimer's dementia (Alzheimer's disease, senile dementia of Alzheimer type etc.), Down's disease, disturbance of memory, prion disease (Creutzfeldt-Jakob disease etc.), mild cognitive impairment (MCI), Dutch-type hereditary cerebral hemorrhage with amyloidosis, cerebral amyloid angiopathy, other degenerated dementia, vascular degenerated mixed dementia, dementia associated with Parkinson's disease, dementia associated with progressive supranuclear paralysis, dementia associated with corticobasal degeneration, diffuse Lewy Bodies Alzheimer's disease, age-related macular degeneration, Parkinson's disease, or amyloid angiopathy etc.
Since compounds of the present invention have several efficacies such as having a potent inhibitory activity against BACE-1 having a high selectivity against other enzymes etc., they can be a drug with less side effects. Moreover they can be a drug having a wide margin of safety by choosing an optically active isomer of appropriate stereochemistry. Further they have a lot of merits such as good metabolic stability, high solubility, high absorbability of oral administration, high bioavailability, good clearance and high transitivity to brain, long half-life, high ratio of non protein binding, lower inhibition of hERG channel and CYP, and/or negative result of Ames Test, and, therefore, they can be superior drugs.
A compound of the present invention may be administrated together with other agent (e.g., other agent for treating Alzheimer's disease such as acetylcholine esterase etc.). The compound can be given in combination with an antidementia drug such as donepezil hydrochloride, tacrine, galantamine, rivastigmine, zanapezil, memantine or vinpocetine, for example.
A compound of the present invention may be orally administrated as powder, granule, tablet, capsule, pill or liquid formulation, or parentally administrated as injection, suppository, formulation of transdermal absorption or inhalation. Also, an effective amount of the compound may be formulated together with medicinal additives suitable for the formulation such as an excipient, binder, moistening agent, disintegrant and/or lubricant etc.
Dose of a compounds of the present invention depends on condition of diseases, route of administration, age and body weight of a patient, but in the case of oral administration to an adult, the dose range is usually 0.1 μg to 1 g/day, preferably 0.01 to 200 mg/day and in the case of parenteral administration the dose range is usually 1 μg to 10 g/day, preferably 0.1 to 2 g/day.

Reference Example 1




The 1st step: Compound (1) (101.5 g) was cooled to −18° C. and conc. sulfuric acid (400 ml) was added dropwise in 65 minutes while the inner temperature was kept at −15° C. or below.

Test Example Assay of β-Secretase-Inhibiting Activity
Forty eight point five μL of substrate peptide solution (Biotin-XSEVNLDAEFRHDSGC-Eu: X-ε-amino-n-capronic acid, Eu=Europium cryptate) was added to each well of 96-hole half-area plate (a black plate: Corning Incorporated), and after addition of 0.5 μl of the test sample (dissolved in N,N′-dimethylformaldehyde) and 1 μl of Recombinant human BACE-1 (R&D Systems), the reaction mixture was incubated at 30° C. for 3 hours. The substrate peptide was synthesized by reacting Cryptate TBPCOOH mono SMP (CIS bio international) with Biotin-XSEVNLDAEFRHDSGC (Peptide Institute, Inc.). The final concentrations of the substrate peptide and Recombinant human BACE-1 were adjusted to 18 nM and 7.4 nM respectively, and the reaction was performed in sodium acetate buffer (50 mM sodium acetate, pH 5.0, 0.008% Triton X-10).
After the incubation for reaction, 50 μl of 8.0 μg/ml Streptavidin-XL665 (CIS bio international) dissolved in phosphate buffer (150 mM K2HPO4—KH2PO4, pH 7.0, 0.008% Triton X-100, 0.8 M KF) was added to each well and left stand at 30° C. for an hour. After then, fluorescence intensity was measured (excitation wavelength: 320 nm, measuring wavelength: 620 nm and 665 nm) using Wallac 1420 multilabel counter (Perkin Elmer life sciences). Enzymatic activity was determined from counting ratio of each wavelength (10,000×Count 665/Count 620) and 50% inhibitory concentration against the enzymatic activity was calculated. IC50 values of the test compounds are indicated in Table 139.
