FIELD OF THE INVENTION [0001]
This invention relates to a pharmaceutical, particularly a novel carboxylic acid derivative or a pharmaceutically acceptable salt thereof which is useful as an insulin secretion promoter or a preventive or therapeutic agent for diabetes mellitus.
BACKGROUND OF THE INVENTION [0002]
Diabetes mellitus is a disease having chronic hyperglycemia as the main symptom, which is developed by the absolute or relative shortage of insulin action. It is roughly divided into insulin-dependent diabetes mellitus (IDDM) and non insulin-dependent diabete: mellitus (NIDDM) based on its clinical characteristics. In the non insulin-dependent diabetes mellitus (NIDDM), reduction of insulin secretion from pancreatic (3 cells is one of the main causes of the onset of the disease, and hyperglycemia after meals by initial stage insulin secretion disorders is particularly observed. [0003]
Recently, it was confirmed by large scale clinical tests that correction of hyperglycemia after meals is important for the onset and progress suppression of diabetic complications. In addition, it has been reported that arteriosclerosis is developed during a period of hyperglycemia alone, and that continuation of slight hyperglycemia after meals increases mortality rate caused by cardiovascular diseases and the like. This suggests that even when it is slight, hyperglycemia after meals is an independent risk factor of cardiovascular death. Based on the above findings, necessity of a drug therapy for hyperglycemia after meals has been recognized. [0004]
At present, a sulfonylurea (SU) agent is the main current as an insulin secretion promoter, but it is known that this is apt to cause hypoglycemia and induces secondary invalidity due to exhaustion of the pancreas under a long period of time of its administration In addition, though the SU agent is effective in controlling blood glucose level during meals, it is difficult to suppress hyperglycemia after meals.
[0005]
GPR40 is a G protein-coupled receptor identified as a fatty acid receptor, which is highly expressed in (5 cells of the pancreas, and it has been reported that this is concerned in the insulin secretion action of fatty acids (Non-patent Reference 1).
Accordingly, a GPR40 receptor agonist is expected to be effective in correcting hyperglycemia after meals based on its insulin secretion promoting action, and therefore is useful as a preventive or therapeutic agent for insulin-dependent diabetes mellitus (IDDM), non insulin-dependent diabetes mellitus (NIDDM) and their boundary type (abnormal glucose resistance and fasting blood glucose level) slight diabetes mellitus.

Pharmacological activities of the compounds of the invention were confirmed by the test methods shown below.
Test method 1: GPR40 agonist activity measurement i) Cloning of human GPR40
In accordance with the following procedure, complete length sequence of GPR40 was obtained by a PCR method using a human genomic DNA (Clontech) as the template.
25
An oligonucleotide consisting of the nucleotide sequence represented by SEQ ID NO:l was used as the forward primer, and an oligonucleotide consisting of the nucleotide sequence represented by SEQ ID NO:2 as the reverse primer. In this connection, a nucleotide sequence containing aXbal recognition sequence is added to the %7 end of each of the aforementioned forward primer and reverse primer. In the PCR, a cycle consisting of 94°C (15 seconds)/55°C (30 seconds)/72°C (1 minute) was repeated 30 times using a Taq DNA polymerase (Ex Taq DNA polymerase; Takara Bio) in the presence of 5% dimethyl sulfoxide (DMSO). As a result, a DNA fragment of about 0.9 kbp was amplified. This DNA fragment was digested withXbal and then inserted into thecal site of a plasmid pEF-BOS-dhfr (Nucleic Acids Research, 18, 5322, 1990) to obtain a plasmid pEF-BOS-dhfr-GPR40.
Nucleotide sequence of GPR40 gene in the plasmid pEF-BOS-dhfr-GPR40 was determined by the dideoxy terminator method using a DNA sequencer (ABI 377 DNA Sequencer; Applied Biosystems). Nucleotide sequence of the GPR40 gene was as the nucleotide sequence represented by SEQ ID NO:3. The nucleotide sequence represented by SEQ ID NO:3 was possessed of an open reading frame (ORF) of 903 bases, and the amino acid sequence deduced from this ORF (300 amino acids) was as the amino acid sequence represented by SEQ ID NO:4. ii) Preparation of GPR40 stable expression cell
A CHO dhfr cell (a dihydrofolate reductase (dhfr) gene-deficient CHO cell) was used as the cell for expressing GPR40 protein. In addition, the plasmid pEF-BOS-dhfr-GPR40 obtained in the aforementioned i) was used as the expression plasmid for expressing the GPR40 protein. The CHO dhfr cell in 10% fetal calf serum (FCS)-containing aMEM medium was inoculated into a 6 well plate and cultured overnight to a stage of 80 to 90% confluent, and then gene transfer of 2 pig per well of the plasmid pEF-BOS-dhfr-GPR40 was carried out using a transfection reagent (Lipofectamine 2000; Invitrogen). After 24 hours of the culturing since the gene transfer, the cells were diluted and inoculated again. In that case, the aMEM medium containing 10% FCS was changed to aMEM medium which contains 10% FCS but does not contain nucleic acids. After 20 days of culturing, the thus formed colonies of cells were individually recovered and cultured to obtain CHO cells stably expressing GPR40. Cells showing high reactivity for integral ligands oleic acid and linoleic acid were selected from them.
26
iii) GPR40 agonist activity measurement
This test was measured by FLIPR (registered trade mark, Molecular Device) using change in the intracellular calcium concentration as the index. The test method is shown below.
A human GPR40-expressed CHO cell strain was inoculated in 6 x 103 cells per well portions into a 384 well black plate (Becton-Dickinson). A Calcium-3 assay kit (Molecular Device) was used as the luminescence pigment and dissolved in 10 ml per bottle of HBSS-HEPES buffer (pH 7.4, 1 x HBSS, 20 mM HEPES, Invitrogen). A 35.68 mg portion of probenecid (Sigma) was dissolved in 250 ul of 1 M NaOH and then adjusted by adding 250 ul of HBSS-HEPES buffer. The fluorescence pigment solution was prepared by mixing 16 ml of HBSS-HEPES buffer, 640 ul of the fluorescence pigment and 32 ul of probenecid, per plate. The medium in the plate was discarded, and the fluorescence pigment solution was dispensed in 40 ul per well portions and incubated at room temperature for 2 hours. Each compound to be tested was dissolved in DMSO, diluted with HBSS-HEPES buffer and then dispensed in 10 ul portions into the plate to start the reaction and measure change in the intracellular calcium concentration by FLIPR. EC50 values of the compounds to be tested were calculated from the dose-response curve of fluorescence intensity changes one minute after the measurement.
The test results are shown in Table 1. Ex indicates compound numbers of Examples which are described later.

By purifying the thus obtained residue by a silica gel column chromatography (hexane-ethyl acetate), a white solid (393 mg) was obtained. 1 M Sodium hydroxide aqueous solution (3.0 ml) was added to a mixture of the thus obtained white solid, ethanol (5 ml) and THF (5 ml) and stirred at room temperature for 20 hours. 1 M Hydrochloric acid (3.0 ml) was added to the reaction solution, followed by extraction with ethyl acetate. The organic layer was washed with saturated sodium chloride aqueous solution and then dried with anhydrous magnesium sulfate. The desiccant was removed and the solvent was evaporated under a reduced pressure. 1 M Sodium hydroxide aqueous solution (0.823 ml) was added to a THF (5 ml) solution of the thus obtained residue and the solvent was evaporated under a reduced pressure. Diethyl ether was added to the thus obtained residue and the thus formed solid A was collected by filtration. By drying with heating under a reduced pressure, sodium 3-(2-fluoro-4- {[ 1 -(2-phenoxyethyl)-1,2,3,4-tetrahydroquinolin-5 -yl]methoxy }phenyl)propanoate (328 mg) was obtained as a white solid. [0154] Example 40
Under ice-cooling, lithium hydroxide monohydrate (150 mg) was added to a mixture of ethyl 3-[2-fluoro-4-([(2-nitrophenyl)sulfonyl] {[ I -(3-phenylpropyl)-1,2,3,4-tetrahydroquinolin-5-yl]methyl}amino)phenyl]propanoate (591 mg), mercaptoacetic acid (0.13 ml) and DMF (6 ml) and, after warming up to room temperature, stirred for 2 hours. Saturated sodium bicarbonate aqueous solution was added to the reaction solution, followed by extraction with ethyl acetate. The organic layer was washed with saturated sodium bicarbonate aqueous solution and saturated sodium chloride aqueous solution and then dried with anhydrous magnesium sulfate. The desiccant was removed and the solvent was evaporated under a reduced pressure. The residue was purified by a silica gel column chromatography (hexane-ethyl acetate) to obtain ethyl 3-[2-fluoro-4-({[l-(3-phenylpropyl)-l,2,3,4-tetrahydroquinolin-5-yl]methyl}amino)phenyl]propanoate (401 mg) as a light yellow oil.
