Amino alcohol derivatives

BACKGROUND OF THE INVENTION

[0002] The present invention relates to amino alcohol derivatives having excellent immune suppression activity, pharmacologically acceptable salts thereof, esters thereof or other derivatives thereof; to pharmaceutical compositions containing said compounds as an active ingredient; to the use of said compounds in the preparation of said pharmaceutical compositions; and to methods for prevention or treatment of autoimmune diseases, which comprise administering a pharmacologically effective amount of said compound to warm blooded animals in need of such prevention or treatment.

[0003] In another aspect, the present invention relates to optically active novel amino alcohol derivatives (particularly, optically active 4,4-disubstituted oxazolidin-2-one derivatives), which are useful synthetic intermediates for the preparation of said amino alcohol derivatives or other medicaments.

[0004] In yet another aspect, the present invention relates to a novel processes for the excellent selective preparation of optically active 2-substituted 2-amino-1,3-propanediol mono-ester derivatives, which are useful synthetic intermediates for the preparation of said amino alcohol derivatives in optically active form.

[0005] Steroids or antiinflammatory drugs have been used as therapeutic agents for inflammatory responses caused by abnormal immunological responses in diseases related to the immune system such as rheumatoid arthritis and other autoimmune diseases. However, these agents are agents that improve the symptoms, but they do not provide treatment of the causes.

[0006] Although abnormal immunological responses have also been reported to contribute to the pathogenesis of diabetes mellitus and nephritis [Kidney International, 51, 94 (1997); Journal of Immunology, 157, 4691 (1996)], no agents have ever been developed to improve the abnormal immunological responses.

[0007] On the other hand, development of immune suppressors is important for prevention of immunological rejection occurring in organ transplantation or for the prevention or therapy of autoimmune diseases. Nevertheless, well known immunosuppressors such as cyclosporin A (CsA) and tacrolimus (TRL) are known to cause renal toxicity or hepatotoxicity. Although steroids have been administered together with immunosuppressors in order to decrease such adverse effects of the immunosuppressors, the immunosuppressing effects could not be satisfactorily elicited without the adverse events.

[0008] From these backgrounds, many attempts have been made to find compounds exerting excellent immunosuppressing effects with low toxicity.

[0009] The following compounds are known as immunosuppressive agents:

[0010] (1) In the specification of WO94/08943 (EP627406) compounds of formula (a) are disclosed as immunosuppressive agents,

[0011] wherein R is a straight or branched carbon chain which may have, in the chain, a group selected from the group consisting of a double bond, a triple bond, oxygen atom, sulfur atom, —N(R6)— (wherein R6 is a hydrogen atom), optionally substituted arylene, optionally substituted heteroarylene or the like, and which may be substituted, at the chain end thereof, by optionally substituted aryl, optionally substituted cycloalkyl, optionally substituted heteroaryl or the like; and R2, R3, R4, R5 are the same or different and each represent a hydrogen atom, an alkyl group or the like.

[0012] The compounds of formula (a) have two oxymethyl groups (—CH2OR4 and —CH2OR5) as essential groups. The compounds of the present invention, however, have a —CH2OR3 group and a lower alkyl group and are different from the compounds of formula (a) in these substituents.

[0013] In said specification no typical compounds similar to the compounds of formula (I) in the present invention are disclosed at all. Only the following two compounds of the compounds of formula (a) are highly similar in chemical structure to the compounds of formula (I) in the present invention:

[0016] (2) In the specification of WO96/06068 compounds of formula (b) are disclosed as immunosuppressive agents,

[0017] wherein R1, R2 and R3 each are a hydrogen atom or the like; W is a hydrogen atom, an alkyl group or the like; Z is a single bond or an alkylene group; X is a hydrogen atom or an alkoxy group; Y is a hydrogen atom, an alkyl, alkoxy, acyl, acyloxy, amino, acylamino group or the like.

[0018] The compounds of formula (b) essentially have a phenyl group as a basic skeleton. The compounds of formula (I) in the present invention have a thiophene group instead of the phenyl group of compounds of formula (b) and are different from the compounds of formula (b) in the basic skeleton.

[0019] In said specification no typical compounds similar to the compounds of formula (I) in the present invention are disclosed at all. Only the following three compounds of the compounds of formula (b) are highly similar in chemical structure to the compounds of formula (I) in the present invention:

[0023] (3) In the specification of WO98/45249 compounds of formula (c) are disclosed as immunosuppressive agents,

[0024] wherein R1, R2, R3, R4 are the same or different and each represent a hydrogen atom or an acyl group.

[0025] The compounds of formula (c) have two oxymethyl groups (—CH2OR3 and —CH2OR4) as essential substituent groups. The compounds of the present invention have a —CH2OR3 group and a lower alkyl group and are different from the compounds of formula (a) in these substituents. The compounds of formula (c) have a phenyl group between —(CH2)2— and —CO(CH2)4— as a basic skeleton. The compounds of formula (I) in the present invention have a thiophene group instead of the phenyl group of the compounds of formula (c). The present compounds of formula (I) are also different from the compounds of formula (c) in the basic skeleton. The compounds of formula (c) have only a phenyl group at the end of —CO—(CH2)4— group. The compounds of formula (I) in the present invention may have a phenyl group, a cycloalkyl group or a heterocyclic group at the end of the molecule.

[0026] In said specification no typical compounds similar in chemical structure to the compounds of formula (I) in the present invention are disclosed at all. Only the following three compounds of the compounds of formula (c) are highly similar in chemical structure to the compounds of formula (I) in the present invention:

[0029] On the other hand, various optically active substituted amino acid and substituted amino alcohol derivatives (particularly α-substituted amino acid and α-substituted amino alcohol derivatives) exhibit biological activity; are partial components of natural products and pharmaceutical agents; and are important synthetic intermediates. For example, α-methyl-α-vinyl amino acids are useful as an amino acid decarboxylase inhibitor; α-ethynyl-α-methyl amino acids are useful as a glutamic acid decarboxylase inhibitor; ISP-1 (Myriocin), which is isolated from metabolites of Isalia sinclairii, has immune suppression activity; and Conagenine and the like participate in the regulation of immune response through T-cells. From these results, α-substituted amino acid and amino alcohol derivatives are very interesting compounds as a partial component of natural products having biological activity, in the field of biochemistry and in the field of organic synthesis.

[0030] These α-substituted amino acid and amino alcohol derivatives have an asymmetric center(s) and an efficient process for the preparation of one enantiomer thereof has been expected.

[0031] There are a few reports of processes for the preparation of optically active substituted amino acid and amino alcohol derivatives and a few reports of synthetic examples of optically active amino alcohol derivatives such as optically active 4,4-disubstituted oxazolizin-2-one derivatives, which are useful synthetic intermediates of optically active substituted amino acid and amino alcohol derivatives described hereinbefore. For example, there are reports by C. Cativiela et al., Tetrahedron: Asymmetry, 9, 3517 (1998) and Synthesis of Optically active α-amino acids (Pergamon Press) R. M. Williams et al and the methods are largely classified into two groups for preparation of them. The one is a diasteroselective alkylation method using an assisting group for asymmetric synthesis, a typical example being a method described by Seebach in Helv. Chim. Acta., 71, 224 (1988) or the synthesis of α-substituted serine derivatives which are obtained by a highly diastereoselective aldol reaction using chiral bis-lactam ether carboxylic acid esters and Mg(II) and Sn(II) type Lewis acids described by Nagao and Sano et al. in Tetrahedron Lett., 36, 2097 (1995) and Tetrahedron Lett., 36, 4101 (1995). The other one is a synthesis of α-substituted serine derivatives which are obtained by enantioselective enzymatic hydrolysis of prochiral σ-symmetry diester compounds (α-substituted-α-protected malonic acid diesters) and is described by Nagao, Tamai et al., in Chemistry Lett., 239 (1989) and Chemistry Lett., 2381 (1994).

[0032] The former method has multi-step reactions and needs a stoichiometric asymmetric source. The latter method has a reduction step and cannot be used when a compound has a group unstable under reduction conditions.

[0033] There are some reports described hereinbefore but, however the practically useful methods are limited. In general, one enantiomer is optically resolved from a racemic mixture. In this case there is a problem that the total yield of the desired compound is low.

BRIEF SUMMARY OF THE INVENTION

[0034] The present inventors have performed painstaking research to complete these objectives, and found that the amino alcohol derivatives (I) of the present invention exert an excellent immunosuppressive effect with low toxicity and are useful as therapeutic agents for autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis, polymyositis, dermatomyositis, Behcet's syndrome, Chron disease, ulcerative colitis, autoimmune hepatitis, aplastic anemia, scleoderma, idiopathic thrombocytopenic purpura, autoimmune hemolytic anemia, multiple sclerosis, autoimmune bullosis, vulgarity psoriasis, vasculitis syndrome, Wegener's granuloma, uveitis, cryptogenic fibrosing alveolitis, Goodpasture's syndrome, sarcoidosis, allergic granulomatous angitis, bronchial asthma, myocarditis, cardiomyopathy, aortic arch syndrome, myocardial postinfarction syndrome, primary pulmonary hypertension, minimal change nephrotic syndrome, membranous nephropathy, membranoproliferative glomerulonephritis, focal glomerular sclerosis, crescent glomerulonephritis, myasthenia gravis, inflammatory neuropathy, atopic dermatitis, chronic actinic dermatitis, acute polyarthritis, Sydenhan chorea disease, progressive systemic sclerosis, adult onset type diabetes mellitus, insulin dependent diabetes mellitus, juvenile diabetes, atherosclerosis, glomerular nephritis, tuburointerstitial nephritis, primary biliary cirrhosis, primary sclerosing cholangitis, fulminant hepatic failure, viral hepatitis, GVHD, immunological rejection following organ transplantation, contact dermatitis, sepsis or other immunology related diseases, and completed the present invention.

[0035] The present invention provides amino alcohol derivatives which exhibit low toxicity and excellent immune suppression activity, pharmacologically acceptable salts thereof, esters thereof or other derivatives thereof.

[0036] In another aspect, the present invention provides pharmaceutical compositions containing said amino alcohol derivatives, a pharmacologically acceptable salt thereof, an ester thereof, or other derivative thereof as an active ingredient; the use of said compounds in the preparation of said pharmaceutical compositions; or methods for prevention or treatment of the diseases described hereinbefore such as autoimmune diseases and the like, which comprise administering a pharmacologically effective amount of said compound to warm blooded animals (e.g. humans) in need of such prevention or treatment.

[0037] The inventors have made a great effort to solve the problems described hereinbefore about a process for the preparation of optically active amino alcohol derivatives and intermediates thereof.

[0038] In addition they have also made a great effort to find a process for the selective preparation of the optically active amino alcohol compounds of formulae (La) and (Lb). They found that optically active 2-substituted 2-amino-1,3-propanediol mono-ester derivatives of formulae (XLIVa) or (XLWb) are useful intermediate for the preparation and said compounds of formulae (XLIVa) and (XLIVb) can easily be obtained from 2-substituted 2-amino-1,3-propanediol derivatives of formula (XLII) using carboxylic acid vinyl esters of formula (XLIII) in the presence of lipase through selective acylation of one hydroxyl group in good yield.

[0256] In the above formulae the “C2-C20 alkenyl group substituted with an aryl group(s) or a heteroaryl group(s)” in the definition of R4a and R11 represents the C2-C20 alkenyl groups described hereinbefore substituted with the same or different 1 to 3 of the aryl groups described hereinbefore or the heteroaryl groups described hereinbefore.

[0257] In the above formulae the “C2-C20 alkyl group which is substituted with an aryl group(s) or a heteroaryl group(s) and interrupted with a heteroatom(s)” in the definition of R4a and R11 represents the C2-C20 alkyl groups interrupted with a heteroatom(s), described hereinbefore and substituted with the same or different 1 to 3 of the aryl groups described hereinbefore or the heteroaryl groups described hereinbefore.

[0258] The lipase employed in this invention is not particularly limited and the preferred lipase is different depending on the starting material, however, is typically obtained from Pseudomonas sp., Pseudomonas fluorescens, Pseudomonas cepacia, Chromobacterium viscosum, Aspergillus niger, Aspergillus oryzae, Candida antarctica, Candida cylindracea, Candida lipolytica, Candida rugosa, Candida utilis, Penicillium roqueforti, Rhizopus arrhizus, Rhizopus delemar, Rhizopus javanicus, Rhizomucor miehei, Rhizopus niveus, Humicola lanuginosa, Mucor javanicus, Mucor miehei, Thermus aquaticus, Thermus flavus, Thermus thermophilus or the like; or human pancreas, hog pancreas, porcine pancreas or wheat germ. Partially or completely purified enzyme moiety and fixed enzyme can be employed and the most preferred lipase is fixed Pseudomonas sp. [for example, immobilized lipase from Pseudomonas sp. (TOYOBO Kabusiki Kaisya)].

[0259] Preferred vinyl ester derivatives of the carboxylic acid of formula (XLIII, R11COOCH═CH2) employed in this invention are different depending on the starting material, however they are typically a vinyl ester of a straight chain aliphatic acid such as the vinyl ester of n-hexanoic acid, vinyl ester of n-heptanoic acid, vinyl ester of n-pentanoic acid, vinyl ester of acetic acid or the like; and the most preferred one is the vinyl ester of n-hexanoic acid.

[0260] When the compound of formula (I) has a basic group such as amino group, the pharmaceutically acceptable salt can be prepared by the reaction of compound (I) with an acid. When the compound of formula (I) has a carboxy group the pharmaceutically acceptable salt can be prepared by the reaction of compound (I) with a base.

[0261] The preferred salts based on a basic group include a hydrohalogenic acid salt such as a hydrofluoride, hydrochloride, hydrobromide or hydroiodide; an inorganic acid salt such as a nitrate, perchlorate, sulfate or phosphate; a lower alkanesulfonic acid salt such as a methanesulfonate, trifluoromethanesulfonate or ethanesulfonate; an aryl sulfonic acid salt such as a benzenesulfonate or p-toluenesulfonate; an organic acid salt such as an acetate, maleate, fumarate, succinate, citrate, ascorbate, tartrate, oxalate, maleate or the like; an amino acid salt such as a glycine salt, lysine salt, arginine salt, omithine salt, glutamic acid salt or aspartic acid salt and most preferably an organic acid salt.

[0262] On the other hand the preferred salts based on an acid group includes an alkali metal salt such as a sodium salt, potassium salt or lithium salt; an alkaline earth metal salt such as a calcium salt or magnesium salt; a metal salt such as an aluminum salt or iron salt; an inorganic salt such as an ammonium salt; an amine salt such as a t-octylamine salt, benzylamine salt, morpholine salt, glucosamine salt, phenylglycine alkyl ester salt, ethylenediamine salt, N-methylglucamine salt, guanidine salt, diethylamine salt, triethylamine salt, dicyclohexylamine salt, N,N′-dibenzylethylenediamine salt, chloroprocaine salt, procaine salt, diethanolamine salt, N-benzylphenethylamine salt, piperazine salt, tetramethylammonium salt or tris(hydroxymethyl)aminomethane salt; and an amino acid salt such as a glycine salt, lysine salt, arginine salt, omithine salt, glutamic acid salt or aspartic acid salt.

[0263] When the Compound (I), a pharmaceutically acceptable salt thereof, an ester thereof or other derivative thereof are allowed to stand so that they are opened to the atmosphere or are recrystallized, they may absorb water and water may be attached to them to form a hydrate.

[0264] The salts of the present invention encompass such hydrates.

[0265] The compounds of formula (I), pharmaceutically acceptable salts thereof, esters thereof or other derivatives thereof have an asymmetric carbon (s) and can exist as optical isomer(s). In this invention a single optical isomer and a mixture of optical isomers are represented by the single chemical formula (I). The present invention encompasses the optical isomers individually and mixtures thereof in optional ratios. For example, the compounds of formula (I), pharmaceutically acceptable salts thereof, esters thereof or other derivatives thereof have the following partial chemical formula wherein the —NR1R2 group is attached to an asymmetric carbon and the preferred absolute configuration at this asymmetric carbon is the R configuration.

[0266] In the above formulae the “ester” refers to an ester of a compound of formula (I) which has a group capable of being esterified. The ester includes the ester of a hydroxyl group and the ester of a carboxy group. Each ester residual group belongs to a general protecting group in chemical reactions or a protecting group capable of being removed by a biological process such as hydrolysis in vivo.

[0267] The “general protecting group in chemical reaction” can be cleaved by a chemical process such as hydrogenolysis, hydrolysis, electrolysis or photolysis.

[0268] The “general protecting group in chemical reactions” and the “protecting group capable of being removed by a biological process such as hydrolysis in vivo” in the esters of a hydroxyl group have the same meaning as that described above for a hydroxyl protecting group.

[0269] The “general protecting group in chemical reactions” in the ester of a carboxyl group preferably includes a lower alkyl group described hereinbefore; a lower alkenyl group such as ethenyl, 1-propenyl, 2-propenyl, 1-methyl-2-propenyl, 1-methyl-1-propenyl, 2-methyl-1-propenyl, 1-butenyl, 2-butenyl, 1-methyl-2-butenyl, 1-methyl-1-butenyl, 3-methyl-2-butenyl, 1-ethyl-2-butenyl, 3-butenyl, 1-methyl-3-butenyl, 2-methyl-3-butenyl, 1-ethyl-3-butenyl, 1-pentenyl, 2-pentenyl, 1-methyl-2-pentenyl, 2-methyl-2-pentenyl, 3-pentenyl, 1-methyl-3-pentenyl, 2-methyl-3-pentenyl, 4-pentenyl, 1-methyl-4-pentenyl, 2-methyl-4-pentenyl, 1-hexenyl, 2-hexenyl, 3-hexenyl, 4-hexenyl or 5-hexenyl; a lower alkynyl group such as ethynyl, 2-propynyl, 1-methyl-2-propynyl, 2-butynyl, 1-methyl-2-butynyl, 1-ethyl-2-butynyl, 3-butynyl, 1-methyl-3-butynyl, 2-methyl-3-butynyl, 1-ethyl-3-butynyl, 2-pentynyl, 1-methyl-2-pentynyl, 3-pentynyl, 1-methyl-3-pentynyl, 2-methyl-3-pentynyl, 4-pentynyl, 1-methyl-4-pentynyl, 2-methyl-4-pentynyl, 2-hexynyl, 3-hexynyl, 4-hexynyl or 5-hexynyl; a halogenated lower alkyl group described hereinbefore; a hydroxy lower alkyl group such as 2-hydroxyethyl, 2,3-dihydroxypropyl, 3-hydroxypropyl, 3,4-dihydroxybutyl or 4-hydroxybutyl; a lower aliphatic acyl-lower alkyl group such as acetylmethyl; an aralkyl group described hereinbefore; or a silyl group described hereinbefore.

[0270] The “protecting group capable of being removed by a biological process such as hydrolysis in vivo” can be cleaved by a biological process such as hydrolysis in the human body to afford a free acid or a salt thereof. Whether a derivative of formula (I) has such a protecting group can be easily determined. The derivative under investigation is administered intravenously to a test animal such as a mouse or a rat and the body fluids of the test animal are thereafter studied. If the parent compound or a pharmacologically acceptable salt thereof is detected in the body fluids of the test animal, the derivative under investigation is judged to have such a group. The “protecting group capable of being removed by a biological process such as hydrolysis in vivo” preferably includes a lower alkoxy lower alkyl group such as methoxyethyl, 1-ethoxyethyl, 1-methyl-1-methoxyethyl, 1-(isopropoxy)ethyl, 2-methoxyethyl, 2-ethoxyethyl, 1,1-dimethyl-1-methoxyethyl, ethoxymethyl, n-propoxymethyl, isopropoxymethyl, n-butoxymethyl or t-butoxymethyl; a lower alkoxy lower alkoxy lower alkyl group such as 2-methoxyethoxymethyl; an aryloxy lower alkyl group such as phenoxymethyl; a halogenated lower alkoxy lower alkyl group such as 2,2,2-trichloroethoxymethyl or bis(2-chloroethoxy)methyl; a lower alkoxycarbonyl lower alkyl group such as methoxycarbonylmethyl; a cyano lower alkyl group such as cyanomethyl or 2-cyanoethyl; a lower alkylthiomethyl group such as methylthiomethyl or ethylthiomethyl; an arylthiomethyl group such as phenylthiomethyl or naphthylthiomethyl; a lower alkyl optionally substituted with a halogen atom(s) sulfonyl lower alkyl group such as 2-methanesulfonylethyl or 2-trifluoromethanesulfonylethyl; an arylsulfonyl lower alkyl group such as 2-benzenesulfonylethyl or 2-toluenesulfonylethyl; a 1-(acyloxy) lower alkyl group described hereinbefore; a phthalidyl group described hereinbefore; an aryl group described hereinbefore; a lower alkyl group described hereinbefore; a carboxyalkyl group such as carboxymethyl; and an amide-formation residual group of an amino acid such as phenylalanine.

[0271] When the compound of formula (I) in this invention has an amino group and/or a carboxyl group, such a compound can be converted to a derivative other than a pharmacologically acceptable salt or an ester described hereinbefore. The “other derivative” refers to such a derivative, for example, an amide derivative such as an acyl group.

[1399] 4-Cyclohexyloxybut-1-yne

[1400] To anhydrous dichloromethane (950 ml) were added cyclohexanone (32 ml, 0.31 mol), 1, 3-propanediol (33.5 ml, 0.46 mol), triethyl orthoformate (51.5 ml, 0.31 mol), and zirconium chloride (1.44 g, 6.18 mmol) followed by stirring under a nitrogen atmosphere for 1 hour at room temperature. An ice-cold 1N aqueous sodium hydroxide solution (1.51) was added to the reaction mixture, and the reaction solution was extracted with dichloromethane, and then the dichloromethane layer was washed with water. The dichloromethane layer was dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by distillation under reduced pressure to give cyclohexanone trimethyl ketal (26.8 g, 55% yield). To the suspension of zirconium chloride (24.9 g, 0.11 mol) in tetrahydrofuran (500 ml) was slowly added sodium borohydride (20.5 g, 0.54 mmol) under a nitrogen atmosphere followed by stirring for 20 minutes at room temperature. A solution of tetrahydrofuran (170 ml) including cyclohexanone trimethyl ketal (16.9 g, 0.11 mol) obtained above was added dropwise in a nitrogen atmosphere to the reaction solution in an ice bath. After the end of dropping, the reaction solution was stirred overnight at room temperature. To this reaction solution was added ice-cold 2N hydrochloric acid (600 ml) in the ice bath to stop the reaction, and tetrahydrofuran was evaporated in vacuo. The water layer residue was extracted with ethyl acetate, and the ethyl acetate layer was washed with a saturated aqueous sodium chloride solution. The ethyl acetate layer was dried over anhydrous sodium sulfate, and the solvent was evaporated in vacuo. The obtained residue was purified by chromatography on a silica gel column (elution solvent; hexane:ethyl acetate=10:1-5:2) to afford 3-cyclohexyloxypropan-1-ol (13.4 g, 78% yield).

[1401] The obtained 3-cyclohexyloxypropan-1-ol (11.5 g, 72.9 mmol) was dissolved in dichloromethane (240 ml), and then molecular sieve 4 Å (58 g) and pyridinium chlorochromate (23.8 g, 0.11 mol) were added thereto in the ice bath followed by stirring under a nitrogen atmosphere for 1 hour and 40 minutes. The reaction solution was diluted with ether, and then the solution was filtered through Celite. The Celite was washed with diethyl ether, and this filtrate was added to the previous filtrate. The total filtrate was evaporated in vacuo, and the residue was purified roughly by chromatography on a silica gel column (elution solvent; n-hexane:ethyl acetate=20:10:1) to give a crude 3-cyclohexyloxypropionaldehyde (8.6 g).

[1402] A dichloromethane solution (120 ml) of triphenylphosphine (57.7 g, 0.22 mol) in an ice bath were added dropwise to the dichloromethane solution (120 ml) including carbon tetrabromide (36.5 g, 0.11 mol) under a nitrogen atmosphere. After the end of dropping, the reaction mixture was stirred for 5 more minutes. To the reaction solution in the ice bath was added dropwise under a nitrogen atmosphere a dichloromethane solution (90 ml) of the crude 3-cyclohexyloxypropionaldehyde (8.6 g) obtained above, and after dropping, the reaction mixture was stirred for 25 more minutes. The reaction solution was diluted with dichloromethane, and washed with a saturated aqueous sodium hydrogencarbonate solution and then with a saturated aqueous sodium chloride solution. After the dichloromethane layer was dried over anhydrous sodium sulfate, the solvent was evaporated in vacuo. The residue was purified by chromatography on a silica gel column (elution solvent; hexane:ethyl acetate=100:1-33:1) to afford 4-cyclohexyloxy-1,1-dibromobut-1-ene (12.6 g, 55% yield, 2 processes).

[1403] To a tetrahydrofuran solution (130 ml) of 4-cyclohexyloxy-1,1-dibromobut-1-ene (12.6 g, 40.4 mmol) obtained above, was added dropwise under a nitrogen atmosphere at −78° C. the hexane solution of 1.5N n-butyllithium (54 ml, 81.0 mmol). After the end of dropping, the reaction solution was stirred for 1 hour, and then warmed up gradually to room temperature. After the reaction solution was stirred at room temperature for 50 minutes, water was added thereto in the ice bath to terminate the reaction. The resulting reaction solution was extracted with diethyl ether, and the diethyl ether layer was washed with the saturated aqueous sodium chloride solution. The diethyl ether layer was dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by chromatography on a silica gel column (elution solvent; hexane:ethyl acetate=100:1-50:1) to give the title compound (4.35 g, 71% yield).

TEST EXAMPLE 1

[1406] Determination of the Inhibitory Activity Ggainst Host versus Graft Reaction (HvGR) in the Rat.

[1407] (1) Two Strains of Rats (Lewis Rats (Male, 6 Weeks Old, Charles River Japan) and WKAH/Hkm (male, 7 weeks old, SLC Japan)) were used. Five rats (host) per group were used.

[1408] (2) Induction of HvGR

[1409] The spleen cells were isolated from the spleen of the rats and 1×108 cells were suspended in the RPMI640 medium (LIFE TECHNOLOGIES, Rockville Md. USA). One hundred microliter (1×107 cells) of the spleen cell suspension whose cells were isolated from either WKAH/Hkm rats or Lewis rats were subcutaneously injected into the bilateral feet pad of the hindlimbs of the Lewis rat.

[1410] (3) Administration of the Compound

[1411] The compound was suspended in 0.5% tragacanth solution. The suspended compound was orally administered to rats in the drug-treated group (Lewis rats injected with spleen cells isolated from AH/Hkm rats, and treated with the compound) at a volume of 5 ml/kg. The treatment was started on the day of the spleen cell injection, once a day, for 4 successive days. Tragacanth solution (0.5%) was orally administered, instead of the suspension of the test compound, to the rats in the same strain group (Lewis rats injected with spleen cells which were isolated from the Lewis rats) and to the rats in the control group (Lewis rats injected spleen cells isolated from WKAH/HkM rats, and not treated with the test compound).

[1412] (4) Determination Procedures for Inhibitory Activity Against HvGR

[1413] The average weight of the popliteal lymph node of the same strain rats was subtracted from the weight of the popliteal lymph node of the individual rat (popliteal lymph gland weight due to HvGR). The inhibition rate of the popliteal lymph node weight due to HvGR of the individual rat treated with the test compound against the average weight of the control rats was calculated. The inhibitory activity of the test compound was expressed as an ID50 value (mg/kg) calculated from the dose-inhibition rate by the least square method.

[1414] As the results of the present experiment, the compound of the present invention showed an excellent inhibitory activity against HvGR in the rat.

TEST EXAMPLE 2

[1415] Determination of the Inhibitory Activity of the Compounds of the Present Invention on Induction of Adjuvant Arthritis.

[1416] 1. Preparation of Adjuvant

[1417] Heat-killed, Mycobacterium butylricum was suspended in mineral oil at a concentration of 2 mg/ml and sonicated with an ultrasonic apparatus.

[1418] 2. Preparation of the Test Compound.

[1419] The test compound was suspended in 0.5% Tragacanth solution.

[1420] 3. Induction of Adjuvant Arthritis

[1421] The adjuvant prepared as described in 1 was intradermally injected into the right hind paw of the female rats (usually Lewis rats were used) at a volume of 0.05 ml. Five rats per group were used. In one group of rats, adjuvant was not injected for the control group.

[1422] 4. Administration of the Compound

[1423] The compound solution prepared as described in 2 was orally administered to rats from the injection day of the adjuvant, once daily for 21 days, at a dose of 5 ml/kg. Tragacanth solution (0.5%) was orally administered to one group of rats treated with adjuvant (the control group) and also to rats not treated with adjuvant.

[1424] 5. Calculation methods of Inhibitory Activity of the Compound

[1425] The volume of the right hind paw was determined with a plethymometer. The volume of the intact paw was subtracted from the individual volume, and the difference was used as the swelling volume. Then the inhibitory activity of the compound was calculated from the individual swelling volume of rats treated with the compound and that in the swelling volume of the control rats. The ID50 value of the compound was obtained from the doses treated and the average inhibitory rate of the group.

[1426] From the present experiment, the compound in the present invention showed a potent inhibitory activity.
