TECHNICAL FIELD

The present invention relates to a trehalose compound and a pharmaceutical comprising the trehalose compound.

BACKGROUND ART

Adenosine is widely distributed throughout the body, such as in the nervous system, and is involved, through adenosine receptors, in controlling various functions between cells. The adenosine receptors are classified into the subtypes of A1, A2 (2A and 2B), and A3. The tissue distribution and functions of the receptors are beginning to be identified.

Among these adenosine receptors, the human A3 receptor is distributed throughout tissues, such as lung, liver, placenta, brain, aorta, kidney, testicle, heart, etc. This preceptor is activated by inflammation, hypoxia, ischemia, etc., of the aforesaid tissue. In light of the above, an adenosine A3 receptor antagonist is considered useful as an antiasthmatic drug, a therapeutic agent for chronic obstructive pulmonary disease, a brain protection medicine, antiphlogistic, etc.

As an adenosine A3 receptor antagonist, Patent Document 1 discloses a compound having the structure of pyrimidine; Patent Document 2 discloses a compound having the structure of adenine. As is seen in the disclosures of these publications, conventional adenosine A3 receptor antagonists have a common structure with the base of adenosine.

Heretofore, trehalose dimycolate (TDM) and trehalose dicorynomycolate (TDCM) are known as diesters of trehalose. TDM is identified as a glycolipid present on the cell surface of Mycobacterium tuberculosis, and is known to exhibit immune adjuvant activity and antitumor activity. TDCM, an analogue having a shorter carbon chain than that of TDM, is isolated from Corynebacterium spp. TDCM and its stereoisomer are found to respectively exhibit antitumor activity, and cancer metastasis inhibitory activity.

Patent Document 3 discloses diesters of C7-C21 fatty acids and trehalose. However, the trehalose difatty acid esters are used therein as a surfactant. These esters are only mentioned as surfactants, along with trehalose monofatty acid esters, and alkylidene trehalose, and with anionic surfactants, etc.; no specific examples of such diesters are disclosed in the Publication.

Non-Patent Document 1 and Non-Patent Document 2 further disclose the trehalose diester compound shown below.

However, Non-Patent Document 1 merely discloses applying this compound as a measurement sample for FD-MS; Non-Patent Document 2 merely discloses examining the effect of the compound (glycolipid) on a phospholipid membrane.

A pharmaceutical and an adenosine A3 receptor antagonist of the present invention contain the trehalose compound mentioned above.

The trehalose compound of the present invention represented by General Formula (1) (hereinafter sometimes referred to as "Trehalose Compound (1)") can be produced according to, for example, the following Synthetic Scheme 1.

In the synthetic scheme above, Y, Y', and R1-R4 have the same meaning as defined above. Bn represents a benzyl group. Z and Z' represent either a hydrogen atom, a C1-C6 alkoxy group, which are included in the definitions of X and X', or a -OBn group. The scheme above only shows Trehalose Compound 2, etc., being &agr;, &agr;'-trehalose; however, &agr;, &bgr;'-, and &bgr;, &bgr;'-trehalose may also be synthesized in the same manner.

Synthetic Scheme 1 is a process for producing Trehalose Compound (1) by an esterification reaction or an amidation reaction of Trehalose Compound 2, and Carboxylic Acid Compounds 3 and 5.

Among Trehalose Compounds 2 used as a starting material, the one in which Y and Y' are both oxygen atoms may be any of those commercially available, or synthesized from a trehalose, etc., according to a known method. For example, &agr;, &agr;'-trehalose can be easily obtained as it naturally occurs. &agr;, &bgr;'- and &bgr;, &bgr;'-trehalose may be obtained by respectively reacting, in a solvent, a mixture of &agr;- or &bgr;-D-glucopyranose and &agr;-D-glucopyranosyl chloride, in which the hydroxy groups at the 2, 3, 4, and 6 positions are protected, in the presence of AgOTf and a molecular sieve 4A (see, M. Nishizawa et al., Chem. Pharm. Bull., volume 42 (4), pages 982-984, 1994 ). With regard to trehalose, the hydroxy group at the 6 position and other hydroxy groups have different reactivities; therefore, Trehalose Compound 2 in which Y and Y' are both oxygen atoms, can relatively readily be synthesized. A trehalose compound in which Y and Y' are both -NR5-, and a trehalose compound in which one of Y and Y' is an oxygen atom and the other is -NR5-, may be synthesized according to a process disclosed in the document ( Wang J. et al., Bioorganic Medicinal Chemistry, volume 12, pages 6397-6413, 2004 ), or to a similar process thereto. Usable Carboxylic Acid Compounds 3 and 5 employed herein may be any of those commercially available, or synthesized according to Synthetic Schemes 2 to 4 described later.

In the first step of Synthetic Scheme 1 (hereinafter, each step of the schemes is referred sequentially to as "Step 1", etc..), Trehalose Compound 4 is obtained by an esterification reaction or an amidation reaction of Trehalose Compound 2 and Carboxylic Acid Compound 3. Then, Trehalose Compound 6 is obtained by an esterification reaction or an amidation reaction of Trehalose Compound 4 and Carboxylic Acid Compound 5.

Any general reaction method may be applied to such an esterification and amidation reaction, such as, for example, dehydrating methods (including a carbodiimide method), mixed acid anhydride methods, activated ester methods, and the like. In these methods, usable dehydrating agents may be any agent that is usually used in an ester synthesis or amide synthesis from an alcohol or an amine, and a carboxylic acid. Examples include mineral acids, such as hydrogen chloride, sulfuric acid, hydrochloric acid, etc.; organic acids, such as paratoluenesulfonic acid, camphorsulfonic acid, etc.; lewis acids, such as boron fluoride etherate, etc., and carbodiimides.. The reaction conditions of the carbodiimide method, which is one of the dehydrating methods, for example, involve using, as a dehydrating agent, carbodiimides, such as dicyclohexylcarbodiimide, 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride, etc.; and adding a catalyst, such as dimethylaminopyridine, 4-pyrrolidinopyridine, etc. In order to facilitate the reaction, devices, such as a Dean-Stark water separator, which uses, as a solvent, benzene, toluene, etc.; a Soxhlet extractor containing a desiccant, etc., may be used. Examples of usable desiccants include anhydrous magnesium sulfate, molecular sieves (4A, 5A), etc. The proportions of starting material compound, dehydrating agent, and catalyst are not limited, and can be suitably selected from a wide range.

The aforesaid esterification reaction or amidation reaction is usually carried out in a suitable solvent. Usable solvents are not limited as long as the solvent exhibits moderate solubility of a starting material compound, and is inactive having no adverse effects during the reaction.. Examples of such solvents include halogenated hydrocarbons, such as methylene chloride, chloroform, ethane dichloride, etc.; ethers, such as tetrahydrofuran, diethyl ether, monoglyme, etc.; and aromatic hydrocarbons, such as toluene, xylene, etc.

The reaction temperature of the esterification or amidation is not limited, but is usually from 0░C to 200░C, and preferably from room temperature to 100░C. The reaction time is usually from 1 hour to 1 week, and preferably from 1 to 24 hours.

After the reaction is completed, the mixed reaction solution was subjected to general treatments such as separation and removal of the by-product, drying of the product, distilling of the solvent, etc., and then to purification according to a general method, such as silica gel column chromatography.

In the reaction of Step 1, the HY-group at the 6 position of either of the glucoses in Trehalose Compounds 4 can be esterified, etc. Therefore, desired Trehalose Compound 4 in which HY-group at the 6 position was esterified is recovered and purified after the reaction. Alternatively, in order to improve the reaction yield, a HY'-group at the 6 position of Trehalose Compound 2 used as a starting material, not desired to be esterified with Carboxylic Acid Compound 3, may be selectively protected before the reaction is carried out. Then, when the esterification reaction or amidation reaction is completed, such a HY'-group may be selectively deprotected.

Next in Step 2, the HY'-group of Trehalose Compound 2 that was not esterified in Step 1 is esterified or amidated with Carboxylic Acid Compound 5 in the same manner as Step 1 above.

When the objective compound is Trehalose Compound 1 in which both carboxylic acid portions are identical, two steps of esterification reaction, etc., in Synthetic Scheme 1 may be carried out in a single step. Specifically, use of an amount of about 1 mol of Carboxylic Acid Compound 3 per mol of Trehalose Compound 2 allows to produce, as a main product, a monoester or a monoamide, while use of an amount of 2 mol or more of the carboxylic acid compound allows to produce, as a main product, diesters, etc., in which two of the hydroxy groups at the 6 position are esterified by an identical carboxylic acid compound.

Subsequently, Trehalose Compound 6 obtained in Steps 1 and 2 is subjected to a catalytic hydrogenation reaction in a hydrogen atmosphere to produce Trehalose Compound (1) of the present invention. Usable catalysts may be any of those conventionally employed in a contact hydrogenation reaction, such as, for example, platinum oxide, platinum carbon, palladium hydroxide, palladium carbon, Raney nickel, etc. The amount thereof is generally from 0.1 to 50 mass% based on the substrate, and hydrogen pressure is usually from 1 to 100 atmospheres, and preferably 1 to 3 atmospheres.

Such a reaction is usually carried out in a suitable solvent. Usable solvents include any inactive solvents having no adverse effects during the reaction. Examples include alcohols, such as methanol, ethanol, etc.; esters, such as ethyl acetate, methyl acetate, etc.; and halogenated hydrocarbons, such as dichloromethane, chloroform, dichloroethane, etc. Although the reaction temperature is not limited, it is usually from 0░C to 100░C, and preferably from room temperature to 50░C.. The reaction time is usually from 1 to 50 hours, and preferably from 1 to 30 hours.

After the reactions of each step, the resulting solution is subjected to general treatments, such as separation of the catalyst by filtration, distillation of the solvent, etc., and then to purification according to a general method, such as solvent extractions, silica gel column chromatography, etc.

Carboxylic Acid Compound 3, used as a starting material compound in Synthetic Scheme 1, can be produced according to, for example, the following Synthetic Schemes 2 to 4. In Synthetic Schemes 2 to 4, Carboxylic Acid Compound 3 is described as an objective compound. Carboxylic Acid Compound 5, which is also used as a starting material compound, can be produced in the same manner as for Carboxylic Acid Compound 3.

Among the Carboxylic Acid Compounds 3 used as a starting material in Synthetic Scheme 1, Carboxylic Acid Compounds 3a and 3b used for obtaining a compound in which the X group is finally a hydroxy group, may be synthesized according to, for example, Synthetic Scheme 2 bellow.

In the synthetic scheme above, R1, R2, and Bn have the same meanings as defined above. R6 represents a C1-C6 alkyl group; Hal represents a halogen atom, such as a chlorine atom, bromine atom, iodine atom, etc.; Bz represents a benzoyl group; Z and Z' represent either of a hydrogen atom, a C1-C6 alkoxy group, which are both included in the definitions of X and X', or a -OBn group. The scheme above only shows (R)-Compound 8; however, (S)-compound may also be synthesized as explained below. Therefore, four optical isomers at the 2 and 3 positions may be synthesized in Synthetic Scheme 2 above.

Synthetic Scheme 2 is a process for producing carboxylic acid compound in which the Z group is a -OBn group. The produced carboxylic acid compound is used as Carboxylic Acid Compound 3 or 5, which are used as starting materials in Synthetic Scheme 1, to produce Trehalose Compound (1) in which the X group is finally a hydroxy group.

Usable Acetoacetic Ester 6 employed as a starting material may be, as it has a relatively simple structure, any of those commercially available, or synthesized according to a known method.

Step 1 of Synthetic Scheme 2 is a process for synthesizing Compound 7 by subjecting Acetoacetic Ester 6 to an alkyl halide reaction in the presence of a basic compound. The reaction is advantageously conducted in the presence of metal iodides, such as sodium iodide, potassium iodide, etc. Preferable examples of R6, which is a protecting group for carboxyl groups, include methyl, ethyl, isopropyl, t-butyl group, etc.

Any known basic compounds are usable. Preferred are sodium hydride, potassium hydride, n-butyl lithium, and like strong bases. These may be used in combination.

The proportion of Acetoacetic Ester 6 and an alkyl halide is not limited, and is suitably selected from a wide range. It is, however, usually from 1 to 5 mol, and preferably 1 to 1.5 mol of alkyl halide per mol of Acetoacetic Ester 6. Further, the proportion of Acetoacetic Ester 6 and a basic compound is not limited and is suitably selected from a wide range. It is, however, usually from 1 to 1.5 mol, and preferably from 2 to 3 mol of the basic compound per mol of Acetoacetic Ester 6.

The reaction in Step 1 is usually carried out in a suitable solvent. Usable solvents include any inactive solvents having no adverse effects during the reaction. Examples include ethers, such as tetrahydrofuran, diethyl ether, monoglyme, etc.; and aromatic hydrocarbons, such as toluene and xylene, etc.. Although the reaction temperature is not limited, it is usually from -20░C to 100░C, and preferably from -10░C to room temperature. The reaction time is usually from 30 minutes to 30 hours, and preferably from 1 to 10 hours.

In the next Step 2, Compound 7 is reduced by adding a small amount of a base, such as triethylamine, etc., to synthesize Compound 8.

Optically active Compound 8 is produced according to an asymmetric hydrogenation reaction using an asymmetric ligand or a complex thereof as a catalyst. Usable asymmetric ligands or complexes thereof may be any of those as long as they are used in an asymmetric hydrogenation reaction. Examples include a 2,2'-bis(diphenylphosphino)-1, 1'-binaphthyl (BINAP) based complex (e.g. an optically active BINAP-ruthenium complex); diamine complexes, such as optically active 1,2-dianilinoethane-ruthenium complexes, etc.; bis(oxazolynyl) pyridine-rhodium complexes, etc. Among these catalysts, the use of (R) dichloro(2,2'-bis(diphenylphosphino)-1,1'-binaphthyl) ruthenium (hereinafter referred to as "BINAP-Ru") for reduction facilitates the production of (R)-Compound 8 in a high optical yield; use of (S)-BINAP-Ru facilitates the production of (S)-Compound 8 in a high optical yield. The amount used is a catalytic amount, and the proportion is usually from 0.0001 to 0.5 mol, and preferably from 0.001 to 0.01 mol per mol of Compound 7.

The reaction in Step 2 is usually carried out in a suitable solvents. Usable solvents may be any of those having no adverse effects during the reaction. Examples include methanol, ethanol, isopropanol, and like alcohols; tetrahydrofuran, diethyl ether, monoglyme, and like ethers.

Although the reaction temperature is not limited, it is usually from 0░C to 200░C, and preferably from 0░C to 50░C. The reaction time is usually from 1 hour to 5 days, and preferably from 1 hour to 30 hours.

The reaction is carried out in a hydrogen atmosphere using a pressure-resistant container. The hydrogen pressure is usually from 1 to 200 atmospheres, and preferably from 2 to 100 atmosphere.

Next in Step 3, Compound 8 is alkylated with an alkyl halide in the presence of a basic compound to produce Compound 9. The reaction is advantageously carried out in the presence of metal iodides, such as sodium iodide, potassium iodide, etc. Preferable examples of the basic compound include sodium hydride, potassium hydride, n-butyl lithium, LDA (lithium diisopropylamide), and like strong bases. These may be used in combination.

The product produced in the reaction mainly has an anti-conformation of the hydroxy group of Compound 9 and newly introduced alkyl group. Specifically, (R)-Compound 8 produces (RR)-Compound 9, and (S)-Compound 8 produces (SS)-Compound 9 respectively with a high diastereoselectivity of 97% or more.

The proportion of Compound 8 and an alkyl halide is not limited, and may be suitably selected from a wide range. An alkyl halide is usually employed in a proportion of 1 to 5 mol, and preferably 1 to 2 mol per mol of Compound 8.. The proportion of Compound 8 and a basic compound is not limited, and may be suitably selected from a wide range. It is, however, usually from 1 to 10 mol, and preferably from 2 to 4 mol of the basic compound per mol of Compound 8.

Such a reaction is usually carried out in a suitable solvent. Usable solvents include any inactive solvents having no adverse effects during the reaction.

The reaction time is usually from 1 to 30 hours, and preferably from 30 minutes to 5 hours.

Next in Step 4, Compound 9 is subjected to a reductive etherification reaction, and then the resulting product is subjected to hydrolysis so as to synthesize Carboxylic Acid Compound 3a. Specifically, Compound 9 is first treated with trimethylchlorosilane in the presence of a basic compound to give silyl ether. Then, benzaldehyde and triethylsilane are added to the obtained silyl ether, which is subjected to a reductive etherification reaction at a low temperature in the presence of trimethylsilyl triflate as a catalyst to produce a compound having a benzylated hydroxy groups. Further, when R6 is a t-butyl group, an increase, after the reaction, of the temperature of the reaction mixture to room temperature allows the t-butyl group to be released, making it possible to produce the objective Compound 3a in one pot..

In the silylation reaction as the first process of the reaction, usable trimethylsilylation agent may be any of those usually employed in a trimethylsilylation reaction. Examples include chlorotrimethyl silane and like trimethylsilane halides; hexamethyldisilazanes; and bis (trimethylsilyl) urea, etc..

In the reductive etherification reaction as the second step of the reaction, the proportion of benzaldehyde, triethylsilane, and Compound 9 is not limited, and may be selected from a wide range. Triethylsilane and a reagent of Compound 9 each are used usually in a proportion of 1 to 10 mol, and preferably 1 to 2 mol per mol of benzaldehyde..

Further, although the reaction temperature in the process is not limited, it is usually from -80░C to 50░C, and preferably from -80░C to 0░C. The reaction time is usually from 5 minutes to 24 hours, and preferably from 30 minutes to 10 hours.

In Step 5, Compound 10, having a hydroxy group that is sterically inverted, may be synthesized. Specifically, Compound 8 is subjected to a Mitsunobu reaction with dialkyl azodicarboxylate, triphenylphosphine and benzoic acid.

Such a reaction is usually conducted in a suitable solvent. Usable solvents are any of those conventionally used in the Mitsunobu reaction. Examples include aromatic hydrocarbons, such as toluene, chlorobenzene, etc.

The reaction temperature is usually from -50 to 50░C, and preferably -30░C to room temperature. The reaction time is usually 10 minutes to 10 hours, and preferably 30 minutes to 3 hour.

In Step 6, the -OBz group of Compound 10 is deprotected to synthesize Compound 11. Specifically, hydrolysis using an alkyl tin reagent is carried out according to a method, such as Salomon, etc. ( Salomon, C.J.; Mata, E.G.; Mascaretti, O.A., J.Org.Chem., 1994, volume 59, pages 7259-7266 ).

Examples of usable alkyl tin reagent include bistributyltin oxide, bis triethyltin oxide, etc. The proportion of such a tin reagent is usually from 1.5 to 2 mol, and preferably about 1.2 mol per mol of Compound 10.

After the reactions are completed in each step, the objective compounds are recovered and purified according to known procedures, such as silica gel column chromatography, vacuum distillation, etc.

Next in Step 7, the objective Carboxylic Acid Compound 3b is produced from Compound 11 under the same conditions as those applied for producing Carboxylic Acid Compound 3a from Compound 9.

Among Carboxylic Acid Compounds 3 used as a starting material in Synthetic Scheme 1, Carboxylic Acid Compound 3c in which the Z group is a C1-C6 alkoxy group may be produced according to, for example, the following Synthetic Scheme 3.

In the synthetic scheme above, R1, R2, and R6 have the same meaning as defined above. R7 represents a C1-C6 alkyl group. Although (2R, 3R)-compound is only shown as Compound 9 in the scheme above, (2S, 3S)-compounds may also be synthesized as explained in Scheme 2. Further, the conformations at the 3 position of Compounds 9 and 12 sterically maintained may be inverted as described later. Accordingly, four optical isomers as Carboxylic Acid Compounds 3c can be produced in Synthetic Scheme 3.

Synthetic Scheme 3 is a process for producing a carboxylic acid compound utilizing, as a starting material, Compound 9 used in Synthetic Scheme 2. The produced carboxylic acid compound is used as Carboxylic Acid Compounds 3 or 5, which are starting materials in Synthetic Scheme 1, to produce Trehalose Compound (1) in which the X group is finally a C1-C6 alkoxy group.

Step 1 of Synthetic Scheme 3 involves etherification of a hydroxy group of Compound 9. In this step, an alkyl etherification reaction, which is carried out using an alkyl sulfonate in the presence of a basic compound, may be utilized. Use of the aforementioned reagents retains the steric conformation at the 3 position. Examples of usable alkyl sulfonates include alkyl esters of trifluoromethane sulfonic acid, alkyl esters of p-toluenesulfonic acid, etc. Examples of usable methyl etherification reagents include methyl trifluoromethanesulfonate, methyl p-toluenesulfonate, etc. The proportion of Compound 9 and the alkyl sulfonate is not limited, and may be selected from a wide range.

Preferred are organic bases, such as 2,6-t-butylpyridine, 4-dimethylaminopyridine, etc. The proportion of Compound 9 and the basic compound is not limited, and is suitably adjusted. It is, however, usually in a proportion of 1 to 5 mol, and preferably 1 to 2 mol of basic compound per mol of Compound 9..

Such a reaction is carried out in a suitable solvent. Usable solvents may be any inactive solvents having no adverse effects during the reaction. Examples include halogenated hydrocarbons, such as methylene chloride, chloroform, ethane dichloride, etc.; ethers, such as tetrahydrofuran chloride, diethyl ether, etc.; aromatic hydrocarbons, such as toluene, xylene, etc.

Although the reaction temperature is not limited, it is usually from -20░C to 100░C, and preferably from room temperature to 50░C. The reaction time is usually from 1 hour to 2 days, and preferably from 1 hour to 30 hours.

Apart from the alkyl etherification reaction above, when inverting the steric conformation at the 3 position, a hydroxy group may be p-toluenesulfonylated, etc., to form a leaving group, and then an SN2 reaction using a desired C1-C6 alkoxide may be carried out. Any known conditions for an SN2 reaction may be applied to the reaction.

If Compound 12 obtained in Step 1 above is a compound in which R6 is t-C4H9 or prenyl, Carboxylic acid 3c may be produced by decomposing an ester group using trimethylsilyl triflate as a catalyst. In this reaction, the proportion of Compound 12 and trimethylsilyl triflate is not limited, and may be selected from a wide range. Trimethylsilyl triflate herein is usually used in a proportion of 0.05 to 2 mol, and preferably 0.1 to 0.7 mol per mol of Compound 12.

The reaction time is usually 1 hour to 2 days, and preferably 1 hour to 30 hours.

After the reactions are completed in each step, the objective compounds are recovered and purified according to known processes, such as silica gel column chromatography, vacuum distillation, etc.

Among Carboxylic Acid Compounds 3 used as a starting material in Synthetic Scheme 1, Carboxylic Acid Compound 3d in which the Z group is a hydrogen atom may be synthesized according to, for example, Synthetic Scheme 4 below. As necessary, Creger, J.Am.Chem.Soc., volume 92, pages 1397-98, 1970 , may be referred to.

In the synthetic scheme above, R1 and R2 have the same meaning as defined above.

The reaction temperature herein may be set to about room temperature. The reaction time is usually about 2 hours to about 12 hours.

After the reaction is completed, the objective compound is recovered and purified according to known processes, such as silica gel column chromatography, vacuum distillation, etc.

A dried two-necked flask was cooled to -78░C, after which diisopropylamine (5.41 g, 53.5 mmol) was introduced thereto. Then, methyllithium (a 0.98M diethyl ether solution, 45 ml, 44.1 mmol) was added dropwise thereto, and stirred for 10 minutes. The resulting mixture was heated to 0░C, and stirred for another 30 minutes. The reaction solution was cooled to -48░C, the (R)-3-hydroxyoctanoic acid t-butyl ester (3.50 g, 16.2 mmol) obtained in Production Example B-1 was added dropwise thereto, and then the mixture was stirred for 30 minutes. To the obtained mixture was added hexamethylphosphoric triamide (HMPA) (7ml), the mixture was stirred for one minute, then 1-iodobutane (3.87 g, 21.0 mmol) was added dropwise thereto. After the reaction solution was stirred at -48░C for one hour, a saturated ammonium chloride solution was added thereto, and extracted 3 times with diethyl ether. The resulting organic layer was dried with anhydrous magnesium sulfate, filtered, and condensed. The obtained residue was purified by column chromatography (silica gel: 150 g, n-hexane/ethyl acetate =15/1) to produce the target compound (1.98 g, 44%).

TEST EXAMPLE 1 Test for Affinity for Adenosine A3 Receptor

The adenosine A3 receptor affinity of the trehalose compounds obtained in Production Examples F-1 to 18 were measured according to the adenosine A1 receptor binding experiment procedure disclosed in Molecular Pharmacology, volume 53, pages 886-893, (1998 ).

Specifically, ovarium K1 cells of a Chinese hamster (obtained from Euroscreen S.A..; hereunder referred to as "CHO-K1") expressing human recombinant adenosine A3 receptors were cultured in a modified HEPES buffer free of Ca2+ and Mg2+. Subsequently, the cultured CHO-K1 was scraped and homogenized in 50 mM of ice-cooled Tris-HCl (pH 7.4), The resulting mixture was subjected to centrifugation at 48,000 x g for 15 minutes to obtain a cell membrane pellet. The obtained cell membrane pellet was washed twice with another modified HEPES buffer, and then subjected again to centrifugation. The washed cell membrane pellet was suspended again in a small quantity of 50 mM Tris-HCl (pH 7.4).

The concentration of the adenosine A3 receptor in the obtained cell membrane pellet was measured as follows. A 0.5 nM amount of [125I] AB-MECA (a selective radioligand of A3 / A1 receptor (N6-(4-amino-3-iodobenzyl)-5'-(N-methoxy carbamoyl) adenosine)) was added to 20 ÁL of the obtained suspension of the aforesaid cell membrane pellet (containing 2 Ág of protein), which was then subjected to incubation for 60 minutes at 25░C. Thereafter, 50 mM of ice-cooled Tris-HCl (pH 7.4) was added thereto to halt the reaction, and then the cell membrane pellet was filtrated out using a glass fiber filter. The filtered cell membrane pellet was washed 3 times with an ice-cooled buffer so as to remove excessive ligands. The radioactivity in the resulting cell membrane pellet on a filter was measured using a scintillation counter (Type 1470 Automatic Counter; PerkinElmer, Inc.).

Separately, in order to measure nonspecific bindings of [125I] AB-MECA other than to an adenosine A3 receptor, 1 ÁM of [125I] IB-MECA (a selective radioagonist of A3 receptor N6-(3-iodobenzyl)-5'-(N-methoxycarbamoyl) adenosine) was further added to the obtained suspension of the cell membrane pellet, and the same measurement was carried out as in the aforesaid binding experiment. The average specific binding value of [125I] AB-MECA to the adenosine A3 receptor was calculated based on the results obtained in the above experiment. The calculated results are shown below.

  • Kd: 5.9nM
  • Bmax: 1800 fmol/mg protein

The adenosine A3 receptor affinity of each trehalose compound obtained in Production Examples F-1 to 18 was calculated based on the results of the same measurement carried out with respect to the suspension of the aforesaid cell membrane pellet to which 3 ÁM or 10Á of each trehalose compound had been added. Further, in a Comparative Example, the same measurement was carried out with respect to the compounds taught in Non-Patent Document 1 and Non-Patent Document 2 (in the chemical formula of Table 1, R1 = R3 = octyl, R2 = R4 = heptyl, X = X' = OH, and Y = Y' = O). The results are shown in Table 1.
