Definitions

  • the present invention relates to a compound which has amyloid ⁇ production inhibitory activity, and is useful as an agent for treating disease induced by production, secretion and/or deposition of amyloid ⁇ protein.
  • amyloid ⁇ protein the peptide composed of about 40 amino acids residue as is called amyloid ⁇ protein, that accumulates to form insoluble specks (senile specks) outside nerve cells is widely observed. It is concerned that this senile specks kill nerve cells to cause Alzheimer's disease, so the therapeutic agents for Alzheimer's disease, such as decomposition agents of amyloid ⁇ protein and amyloid vaccine, are under investigation.
  • Secretase is an enzyme which cleaves a protein called amyloid ⁇ precursor protein (APP) in cell and produces amyloid ⁇ protein.
  • the enzyme which controls the production of N terminus of amyloid ⁇ protein is called as (3-secretase (beta-site APP-cleaving enzyme 1, BACE-1). It is thought that inhibition of this enzyme leads to reduction of producing amyloid ⁇ protein and that the therapeutic agent for Alzheimer's disease will be created due to the inhibition.

Description

    TECHNICAL FIELD

    • BACKGROUND ART
  • In the brain of Alzheimer's patient, the peptide composed of about 40 amino acids residue as is called amyloid β protein, that accumulates to form insoluble specks (senile specks) outside nerve cells is widely observed. It is concerned that this senile specks kill nerve cells to cause Alzheimer's disease, so the therapeutic agents for Alzheimer's disease, such as decomposition agents of amyloid β protein and amyloid vaccine, are under investigation.
  • Secretase is an enzyme which cleaves a protein called amyloid β precursor protein (APP) in cell and produces amyloid β protein. The enzyme which controls the production of N terminus of amyloid β protein is called as (3-secretase (beta-site APP-cleaving enzyme 1, BACE-1). It is thought that inhibition of this enzyme leads to reduction of producing amyloid β protein and that the therapeutic agent for Alzheimer's disease will be created due to the inhibition.
  • Patent Literature 1 describes the compounds which are similar to those of the present invention, and the compounds have NO synthase enzyme inhibitory activity and are useful for dementia.
  • Patent Literatures 2 to 5 and Non-patent Literatures 1 and 2 describe the compounds which are similar to those of the present invention, and are useful for hypertensive agent, morphine like analgesic, tranquilizers, intermediate for medicament, NPYY5 antagonist, analgesic, or the like, respectively.

  • The effect of the present compound was confirmed by the following test Examples.
    • Test Example 1 Assay of β-Secretase-Inhibiting Activity
  • 48.5 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 21.

  • A test compound was suspended in 0.5% methylcellulose, the final concentration was adjusted to 2 mg/mL, and this was orally administered to male Crg:SD rat (7 to 9 week old) at 10 mg/kg. In a vehicle control group, only 0.5% methylcellulose was administered, and an administration test was performed at 3 to 8 animals per group. A brain was isolated 3 hours after administration, a cerebral hemisphere was isolated, a weight thereof was measured, the hemisphere was rapidly frozen in liquid nitrogen, and stored at −80° C. until extraction date. The frozen cerebral hemisphere was transferred to a homogenizer manufactured by Teflon (registered trade mark) under ice cooling, a 5-fold volume of a weight of an extraction buffer (containing 1% CHAPS ({3-[(3-chloroamidopropyl)dimethylammonio]-1-propanesulfonate}), 20 mM Tris-HCl (pH 8.0), 150 mM NaCl, Complete (Roche) protease inhibitor) was added, up and down movement was repeated, and this was homogenized to solubilize for 2 minutes. The suspension was transferred to a centrifugation tube, allowed to stand on an ice for 3 hours or more and, thereafter centrifuged at 100,000×g and 4° C. for 20 minutes. After centrifugation, the supernatant was transferred to an ELISA plate (product No. 27730, Immuno-Biological Laboratories Co., Ltd.) for measuring β amyloid 1-40. ELISA measurement was performed according to the attached instruction. The lowering effect was calculated as a ratio compared to the brain β amyloid 1-40 level of vehicle control group of each test.

    • Test Example 3 CYP3A4 Fluorescent MBI Test
  • The CYP3A4 fluorescent MBI test is a test of investigating enhancement of CYP3A4 inhibition of a compound by a metabolism reaction, and the test was performed using, as CYP3A4 enzyme expressed in Escherichia coli and employing, as an index, a reaction in which 7-benzyloxytrifluoromethylchmarin (7-BFC) is debenzylated by the CYP3A4 enzyme to produce a metabolite, 7-hydroxytrifluoromethylchmarin (HFC) emitting fluorescent light.
  • The reaction conditions were as follows: substrate, 5.6 μmol/L 7-BFC; pre-reaction time, 0 or 30 minutes; reaction time, 15 minutes; reaction temperature, 25° C. (room temperature); CYP3A4 content (expressed in Escherichia coli), at pre-reaction 62.5 pmol/mL, at reaction 6.25 pmol/mL (at 10-fold dilution); test drug concentration, 0.625, 1.25, 2.5, 5, 10, 20 μmol/L (six points).
  • An enzyme in a K-Pi buffer (pH 7.4) and a test drug solution as a pre-reaction solution were added to a 96-well plate at the composition of the pre-reaction, a part of it was transferred to another 96-well plate so that it was 1/10 diluted by a substrate in a K-Pi buffer, NADPH as a co-factor was added to initiate a reaction as an index (without preincubation) and, after a predetermined time of a reaction, acetonitrile/0.5 mol/L Tris(trishydroxyaminomethane)=4/1 was added to stop the reaction. In addition, NADPH was added to a remaining preincubation solution to initiate a preincubation (with preincubation) and, after a predetermined time of a preincubation, a part was transferred to another plate so that it was 1/10 diluted with a substrate and a K-Pi buffer to initiate a reaction as an index. After a predetermined time of a reaction, acetonitrile/0.5 mol/L Tris(trishydroxyaminomethane)=4/1 was added to stop the reaction. For the plate on which each index reaction had been performed, a fluorescent value of 7-HFC which is a metabolite was measured with a fluorescent plate reader. (Ex=420 nm, Em=535 nm). Addition of only DMSO which is a solvent dissolving a drug to a reaction system was adopted as a control (100%), remaining activity (%) was calculated at each concentration of a test drug added as the solution, and IC50 was calculated by reverse-presumption by a logistic model using a concentration and an inhibition rate. When a difference between IC50 values is 5 μM or more, this was defined as (+) and, when the difference is 3 μM or less, this was defined as (−).
