Definitions

  • the present invention relates to benzylamine analogues, pharmacologically acceptable salts or esters thereof and pharmaceutical compositions containing the same that have superior acetylcholinesterase inhibitory action and selective serotonin reuptake inhibitory action, and which are useful as therapeutic or prophylactic drugs for Alzheimer's disease, depression, Huntington's chorea, Pick's disease, tardive dyskinesia, compulsive disorders or panic disorders.
  • Alzheimer's disease Given the rapid growth of the elderly population, there is an urgent desire for the establishment of a treatment method for senile dementia as typified by Alzheimer's disease, and research and development is being conducted on therapeutic drugs for Alzheimer's disease from various perspectives. Since decreased acetylcholine concentration in the brain and decreased cholinergic function are observed in Alzheimer's disease patients, studies have been conducted on the treatment of Alzheimer's disease using acetylcholine precursor compounds, acetylcholinesterase inhibitors and acetylcholine agonists for the purpose of activating cholinergic function.
  • acetylcholinesterase inhibitors Activation of the central cholinergic nervous system has been demonstrated to be effective for the treatment of mild to moderate cases of Alzheimer's disease by clinical application of acetylcholinesterase inhibitors (Rev. Contemp. Pharmacother., 6, 335 (1995)).
  • Depression is frequently reported as a peripheral symptom in early Alzheimer's disease patients. Treatment using antidepressants has been tried, based on the idea that while impairment of cognitive function is still mild, core symptoms such as cognitive function can be expected to be improved by alleviating the depression (Ann. N.Y. Acad. Sci., 695, 254 (1993)). At present, the brain's serotonin system is widely recognized to be involved in depression. Research is being conducted on drugs that act on serotonin receptors or serotonin reuptake inhibitors, and selective serotonin reuptake inhibitors have been reported to be antidepressants having minimal adverse side effects (Drugs, 32, 481 (1986)).
  • Drugs that are provided with both acetylcholinesterase inhibitory action and selective serotonin reuptake inhibitor action are expected to be able to alleviate depression and improve cognitive function, which are the core symptoms of Alzheimer's disease, and are thought to be more effective therapeutic drugs for Alzheimer's disease than compounds only having acetylcholinesterase inhibitory action.
  • compounds having a similar chemical structure to the compounds of the present invention that also have both acetylcholinesterase inhibitory action and selective serotonin reuptake inhibitory action have heretofore not been known.
  • benzylamine analogues having an amine at the benzyl position have both superior acetylcholinesterase inhibitory action and selective serotonin reuptake inhibitory action, and are useful as therapeutic or prophylactic drugs (particularly therapeutic drugs) for Alzheimer's disease, depression, Huntington's chorea, Pick's disease, tardive dyskinesia, compulsive disorders or panic disorders (and particularly Alzheimer's disease), thereby leading to completion of the present invention.

No. 10/629,108 filed Jul. 28, 2003, which is a continuation-in-part application of International Application PCT/JP02/00400 filed Jan. 22, 2002, the entire contents of which are hereby incorporated by reference herein.
    • BACKGROUND OF THE INVENTION
  • 1. Technical Field
  • The present invention relates to benzylamine analogues, pharmacologically acceptable salts or esters thereof and pharmaceutical compositions containing the same that have superior acetylcholinesterase inhibitory action and selective serotonin reuptake inhibitory action, and which are useful as therapeutic or prophylactic drugs for Alzheimer's disease, depression, Huntington's chorea, Pick's disease, tardive dyskinesia, compulsive disorders or panic disorders.
  • 2. Background Art
  • Given the rapid growth of the elderly population, there is an urgent desire for the establishment of a treatment method for senile dementia as typified by Alzheimer's disease, and research and development is being conducted on therapeutic drugs for Alzheimer's disease from various perspectives. Since decreased acetylcholine concentration in the brain and decreased cholinergic function are observed in Alzheimer's disease patients, studies have been conducted on the treatment of Alzheimer's disease using acetylcholine precursor compounds, acetylcholinesterase inhibitors and acetylcholine agonists for the purpose of activating cholinergic function. Activation of the central cholinergic nervous system has been demonstrated to be effective for the treatment of mild to moderate cases of Alzheimer's disease by clinical application of acetylcholinesterase inhibitors (Rev. Contemp. Pharmacother., 6, 335 (1995)). Serious adverse side effects, namely liver toxicity, which were observed with early acetylcholinesterase inhibitors, have been improved considerably by ensuring inhibitory action specificity of the compounds to acetylcholinesterase and butylcholinesterase, and second generation acetylcholinesterase inhibitors are currently being developed (Neurology, 50, 136 (1998)).
  • Depression is frequently reported as a peripheral symptom in early Alzheimer's disease patients. Treatment using antidepressants has been tried, based on the idea that while impairment of cognitive function is still mild, core symptoms such as cognitive function can be expected to be improved by alleviating the depression (Ann. N.Y. Acad. Sci., 695, 254 (1993)). At present, the brain's serotonin system is widely recognized to be involved in depression. Research is being conducted on drugs that act on serotonin receptors or serotonin reuptake inhibitors, and selective serotonin reuptake inhibitors have been reported to be antidepressants having minimal adverse side effects (Drugs, 32, 481 (1986)). Drugs that are provided with both acetylcholinesterase inhibitory action and selective serotonin reuptake inhibitor action are expected to be able to alleviate depression and improve cognitive function, which are the core symptoms of Alzheimer's disease, and are thought to be more effective therapeutic drugs for Alzheimer's disease than compounds only having acetylcholinesterase inhibitory action. However, compounds having a similar chemical structure to the compounds of the present invention that also have both acetylcholinesterase inhibitory action and selective serotonin reuptake inhibitory action have heretofore not been known.
    • SUMMARY OF THE INVENTION
  • As a result of seeking to develop compounds having both superior acetylcholinesterase inhibitory action and selective serotonin reuptake inhibitory action, and conducting earnest research over an extended period of time on the synthesis of various benzene derivatives and their pharmacological activity, the inventors of the present invention found that benzylamine analogues having an amine at the benzyl position have both superior acetylcholinesterase inhibitory action and selective serotonin reuptake inhibitory action, and are useful as therapeutic or prophylactic drugs (particularly therapeutic drugs) for Alzheimer's disease, depression, Huntington's chorea, Pick's disease, tardive dyskinesia, compulsive disorders or panic disorders (and particularly Alzheimer's disease), thereby leading to completion of the present invention.

  • Whole brains of mice were used as a source of acetylcholinesterase. Acetylcholinesterase activity was determined according to a previously described method (Biochem Pharmacol 7: 88, 1961). Briefly, 10 μl of dimethylsulfoxide (DMSO)-dissolved test substance was added to 3 ml of phosphate buffer solution containing the brain homogenate [2990 μl of 100 mM phosphate buffer solution (100 mM of Na2HPO4 and 100 mM of NaH2PO4, pH=7.4)+10 μl of brain homogenate] and preincubated for 10 min at room temperature. Then 50 μl of dithiobisnitrobenzoate (DTNB) solution (395 mg of DTNB and 150.5 mg of NaHCO3 dissolved in 100 ml of 100 mM phosphate buffer solution) was added to the solution which was again preincubated for 20 min at room temperature. Fifty microliters of acetylthiocholine iodide (ATC) solution (8.676 mg of ATC dissolved in 1 ml of distilled water) were added to the solution to initiate the response. Immediately and 8 min after the response was started, absorbance (412 nm) was determined and the inhibition rate (%) caused by the test substance was calculated. Furthermore, the concentration of the test substance needed to inhibit acetylcholinesterase activity by 50% (IC50) was calculated.
    • Test Example 1b Serotonin Re-Uptake Inhibitory Activity
  • Serotonin re-uptake inhibitory activity was determined using synaptosome prepared from rat whole brains except the cerebellums. Briefly, 10 μl of DMSO solution-dissolved test substance (control group; DMSO solution alone) was added to 1 ml of synaptosome and incubated for 5 min at 37° C. (in the control, DMSO alone was added to the synaptosome and incubated at 4° C.). Furthermore, 10 μl of [3H]5-HT solution (final concentration: 10 μM as a total concentration of 5-HT, 100 nM as [3H]15-HT) was added and incubated for 5 min at 37° C. Then 4 ml of ice-cold saline was added to stop the response. The response solution was filtered, 4 ml of saline was added, and the solution was once again filtered. Furthermore, 5 ml of Pico-Fluor was added, then 3H levels on filter papers were counted by a liquid scintillation counter. Concentrations of test compounds to inhibit serotonin re-uptake by 50% (IC50) were calculated.

The homogenised solution (100 μL) was mixed with acetylthiocholine solution (60 mM, 10 μL) and incubated for 60 sec at 26° C. After centrifugation at 10,000 rpm for 10 min, the supernatant (10 μL) was mixed with dithionitrobenzoic acid solution (10 mM, 200 μL) and left for 20 min at room temperature for the color to develop. Then the absorbance (415 nm) was determined with a microplate-reader. Relative inhibitory activity (%) of the test compound against the production level of thiocholine in the brain homogenate of the control group (100%), in which the test compound was not administered, was calculated.
    • Test example 2b Serotonin Transporter Binding Inhibition Test
  • Sixty min after oral administration of the test compound to a mouse, the whole brain except the cerebellum was removed. The removed brain was homogenized in 50 mM Tris HCl buffer solution (pH: 7.7) with the volume of buffer corresponding to 3 times the brain tissue weight. The homogenised solution (250 μL) was mixed with [3H]citalopram (NEN Life Science Products: final concentration 0.77 nM) (1) in the presence of fluvoxamine (final-concentration: 1 mM) or (2) in the absence of fluvoxamine, and incubated for 60 sec at 25° C. After Tris HCl buffer solution (2.5 ml) was added, the solution was centrifuged at 3,000 rpm for 6 min. The sediment was recovered. After this process was repeated twice, the sediment was suspended in 1 mL of the buffer solution and Pico-Fluor-40 (4 mL) added. Then the radioactivity was determined with a liquid scintillation counter (ALOKA, LSC-3500). Serotonin transporter protein binding level was calculated by subtraction of the radioactivity in the presence of citalopram (2) from that in the absence of citalopram (1).
  • Compounds of the present invention showed potent inhibitory activities against both acetylcholinesterase activity and serotonin transporter protein binding in the brains of mice following oral administration. Thus compounds of the present invention are useful as safe and effective remedies.
