Description

TECHNICAL FIELD

The present invention relates to a heterocyclic compound that specifically binds to the component protein Skp2 of ubiquitin ligase (SCF^Skp2) and, for example, inhibits the dissociation of p27^Kip1 from SCF^Skp2 complex, and that is useful for subsequently inhibiting the progression of the ubiquitination of p27^Kip1 and inhibiting the degradation of p27^Kip1 by a proteasome; a p27^Kip1 ubiquitination inhibitor (or a p27^Kip1 degradation inhibitor) containing the compound; and an agent for preventing and/or treating a cell proliferative disease (for example, an anticancer agent).

BACKGROUND ART

p27^Kip1 is one of cyclin-dependent kinase inhibitors (CDK Inhibitors) that are a factor negatively regulating cell cycle progression. Clinical studies have revealed that the accelerated degradation of p27^Kip1 decreases the expression amount of p27^Kip1 in highly malignant cancer cells. Moreover, clinical studies suggest that the decrease in the expression amount of p27^Kip1 closely relates to the progression, recurrence and metastasis of cancer and the decrease of survival ratio of patients with cancer.

p27^Kip1 is mainly decomposed by ubiquitin-proteasome system to decrease in the amount of expression. More specifically, if threonine 187 of p27^Kip1 is phosphorylated, p27^Kip1 is isolated from a cyclin-CDK complex to specifically bind to Fbox protein (Skp2) of a ubiquitin ligase comprising a SCF (Skp1/Cullin1/Fbox) complex. Whereas, a ubiquitin conjugating enzyme (E2) binds to the ubiquitin ligase complex through Rbx1 in the complex, and p27^Kip1 binding to Skp2 is ubiquitinated through the enzyme. By the repetition of the ubiquitination reaction, the polyubiquitinated p27^Kip1 is recognized by a proteasome to be decomposed.

Thus the degradation mechanism of p27^Kip1 has been explained molecular-biologically, but an effective p27^Kip1 degradation inhibitor is still not known.

Incidentally, WO2005/012269 (Patent Document 1) discloses a compound represented by following formula as a physiologically active inhibitor of LPA acting as an intercellular messenger.

This document also discloses that the compound is useful as a treating or preventing agent for a cell proliferative disease, which is one of diseases in which a LPA receptor participates. The document, however, is silent on the relationship between the compound and an intracellular protein.

SUMMARY OF THE INVENTION

Problems to be Solved by the Invention

It is therefore an object of the present invention to provide a novel heterocyclic compound or a salt thereof, a degradation inhibitor of p27^Kip1, a ubiquitination inhibitor of p27^Kip1, a preventing and/or treating agent for a cell proliferative disease, and a pharmaceutical composition.

Another object of the present invention is to provide a novel heterocyclic compound or a salt thereof effective in selectively inhibiting the degradation of p27^Kip1, a degradation inhibitor of p27^Kip1, a ubiquitination inhibitor of p27^Kip1, a preventing and/or treating agent for a cell proliferative disease, and a pharmaceutical composition.

It is still another object of the present invention to provide a novel heterocyclic compound or a salt thereof effective in selectively inhibiting the ubiquitination of p27^Kip1, a degradation inhibitor of p27^Kip1, a ubiquitination inhibitor of p27^Kip1, a preventing and/or treating agent for a cell proliferative disease, and a pharmaceutical composition.

Means to Solve the Problems

As a compound acting on the ubiquitin-proteasome system, a proteasome inhibitor VELCADE (registered trademark) (manufactured by Millennium, generic name “Bortezomib”) non-selectively inhibits substrate proteins because a proteasome has a function to decompose various ubiquitinated substrate proteins. Moreover, MLN4924, which has been reported as an inhibitor of NAE (NEDD8-activating enzyme), acts on all of Cullin-RING ligases (CRLs) containing Cullin protein as a constituent element, thereby inhibiting the degradation of all substrate proteins to be ubiquitinated.

Thus, the inventors of the present invention made intensive studies to achieve the above objects based on the knowledge and finally found that a heterocyclic compound or a salt thereof having a plurality of rings linked to each other through a specific linker (1) specifically binds to the component protein Skp2 of the ubiquitin ligase (SCF^Skp2) and, for example, inhibits the dissociation p27^Kip1 from SCF^Skp2 complex, as a result can inhibit the ubiquitination of p27^Kip1 and the degradation of p27^Kip1 by the proteasome followed by the ubiquitination, (2) can selectively inhibit the degradation of p27^Kip1 at a high activity, recover the expression amount of β27^Kip1, and thus avoid increase in the non-selective expression of proteins other than p27^Kip1, and (3) can induce cell death (apoptosis) of cells having a decreased expression amount of p27^Kip1 (such as cancer cells). The present invention was accomplished based on the above findings.

Effects of the Invention

The compound or the salt thereof of the present invention specifically binds to the component protein Skp2 of the ubiquitin ligase (SCF^Skp2) and, for example, inhibits the dissociation of p27^Kip1 from SCF^Skp2 complex, as a result can inhibit the ubiquitination of p27^Kip1 and the degradation of p27^Kip1 by the proteasome followed by the ubiquitination. Moreover, since, differently from proteasome inhibitor or the like, the compound or the salt thereof can selectively inhibit the degradation of p27^Kip1, the degradation or increased expression of proteins other than p27^Kip1 can be avoided. Further, since the action of the compound or the salt thereof of the present invention on cells having a decreased expression of p27^Kip1 (such as cancer cells) allows the expression amount of p27^Kip1 to be recovered to induce the cell death (apoptosis). The compound or the salt thereof is useful for preventing and/or treating a cell proliferative disease (for example, cancer, rheumatism, diabetes, adiposis, endometriosis, prostatomegaly, and inflammation).

There is a report that the component protein Skp2 of the ubiquitin ligase (SCF^Skp2) is overexpressed in highly malignant cancer cells in which the degradation of p27^Kip1 is accelerated. For such highly malignant cancer cells, the compound or the salt thereof of the present invention binds to Skp2 due to a high activity thereof and can selectively inhibit the ubiquitination of p27^Kip1, effectively induce apoptosis accompanied by the expression amount of p27^Kip1 and show a high anticancer action.

The present invention also includes a salt (e.g., a salt with a pharmacologically or physiologically acceptable acid or base) of the compound represented by the formula (1). The acid for forming such a salt may include an inorganic acid (e.g., hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, and phosphoric acid) and an organic acid (e.g., an organic carboxylic acid such as acetic acid, propionic acid, trichloroacetic acid, trifluoroacetic acid, oxalic acid, succinic acid, fumaric acid, or maleic acid; an hydroxycarboxylic acid such as lactic acid, malic acid, tartaric acid, or citric acid; and a sulfonic acid such as methanesulfonic acid or toluenesulfonic acid). As the base, there may be mentioned, for example, an inorganic base (such as ammonia; an alkali metal hydroxide such as sodium hydroxide or potassium hydroxide; an alkali metal carbonate; an alkaline earth metal hydroxide such as calcium hydroxide or magnesium hydroxide; and an alkaline earth metal carbonate such as calcium carbonate) and an organic base [for example, an aliphatic amine (e.g., an alkylamine such as triethylamine; an alkanolamine such as ethanolamine; and a polyamine such as an alkylenediamine), an alicyclic amine (e.g., a dicycloalkylamine such as dicyclohexylamine), an aromatic amine (e.g., an N-alkyl-substituted aniline such as N,N-dimethylaniline), and a heterocyclic amine (e.g., a 5- or 6-membered ring such as pyrrolidine, pyridine, or morpholine)]. These acids or bases may be used alone or in combination.

The compound or the salt thereof of the present invention may be an anhydride or a hydrate or may be a solvate (e.g., a solvate of an organic solvent such as ethanol). Moreover, the compound or the salt thereof of the present invention also includes a hydrate or solvate of the compound of the formula (1) or the salt thereof, and in addition, an isolated crystal (e.g., a polymorphic crystalline substance). Moreover, the compound or the salt thereof according to the present invention also includes a tautomer, optically active substance having an asymmetric carbon atom (such as (R)-body, (S)-body, diastereomer), or racemic body of the compound of the formula (1) or the salt thereof, or a mixture of these compounds. Further, the end group or heterocyclic group, or other groups of the compound or the salt thereof may be modified for forming a pro-drug which expresses an activity in a living body (or an active metabolite). The pro-drug may include, for example, a compound which expresses an activity by metabolism such as hydrolysis, oxidation, reduction, or transesterification (for example, an ester body, ether body, alcohol body, or amide body of the compound of the formula (1)). The compound or the salt thereof of the present invention has a high safety.

[Production Process]

The compound represented by the formula (1) or the salt thereof can be produced by linking a unit represented by the group A, a unit represented by the ring B, a unit represented by the linker L, and a unit represented by the ring C, and the order to be linked is not particularly limited to a specific one. For example, the compound or the salt thereof can be produced according to the following reaction scheme (i):

wherein L¹ and L² represent groups which allow to react with each other to form the linker L; the group A, the ring B, the ring C, L and n have the same meanings as defined above.

In the reaction step (i), the groups represented by L¹ and L² are not particularly limited to a specific one as far as these groups allow to react with each other to form the linker L. The groups L¹ and L² are suitably selected depending on the species of the linker L, and may for example be functional groups which allow to react with each other to form a bond. Each one of the groups L¹ and L² may be the functional group (end group) or a group having the functional group. The functional group may include a haloalkyl group, a hydroxyl group, an aldehyde group (formyl group), a carboxyl group, a carbazoyl group, a hydroxamic acid group, an amino group, a hydrazino group, an aminocyano group, an isocyanate group, an isothiocyanato group, and other groups. In the group having the functional group, the residue that the functional group is removed from the group having the functional group may include an alkylene group.

More specifically, the compound represented by the formula (1) or the salt thereof can be prepared according to the following reaction scheme (ii):

wherein the groups J and K are located at an end of the compound having the ring B and an end of the compound having the ring C, respectively, and allow to react with each other to link the compound having the ring B and the compound having the ring C; L^1a and L^2a are the same or different and each represent an alkylene group; L³ represents a linker represented by any one of the following formulae (1-a) to (1-i); j and k are the same or different and each are 0 or 1; and the group A, the ring B, the ring C and n have the same meanings as defined above.

In the reaction step (ii), the groups J and K are not particularly limited to a specific one as far as these groups allow to react with each other to link the compound having the ring B and the compound having the ring C. These groups are suitably selected depending on the species of the basic skeleton L³ of the linker L [-(L^1a)_j-L³-(L^2a)_k-]. Concrete examples of the combination of the groups J and K corresponding to the basic skeleton L³ of the linker L are shown in Table 5.

TABLE 5

(1-a)	Isocyanate group	Hydroxyl group
(1-b)	Carboxyl group	Hydrazino group
(1-c)	Carbazoyl group [—C(O)—NH—NH2]	Formyl group

(1-g)	Haloalkyl group	Hydroxyl group
(1-h)	Isothiocyanato group	Hydroxyl group

In Table 5, as the combination of the groups J and K, the combination in which the left end and the right end of the linker L are linked to the ring B and the ring C, respectively, is shown. Use of the compound of the ring B having the group J and the compound of the ring C having the group K can easily produce the compound in which the left end and the right end of the linker L are linked to the ring C and the ring B, respectively.

The alkylene group (including an alkylidene group) represented by each of L^1a and L^2a may include a straight chain or branched chain alkylene group (for example, a C_1-4alkylene group, and preferably a C_1-2alkylene group) such as methylene, 1,1-ethanediyl, ethylene (1,2-ethanediyl), 1,1-propanediyl, propylene (1,2-propanediyl), trimethylene, or tetramethylene group. The species of L^1a and L^2a may be the same or different from each other.

In the formation reaction of the linker, the ratio (the amount to be used) of the compound (7-a) [or the compound (7-c)] and the compound (7-b) [or the compound (7-d)] may be the ratio at which L¹ (end group J) and L² (end group K) are equivalent or almost equivalent. The ratio (molar ratio) of the compound (7-a) [or the compound (7-c)] relative to the compound (7-b) [or the compound (7-d)] may for example be about 2/1 to 1/2, preferably about 1.5/1 to 1/1.5, and more preferably about 1.2/1 to 1/1.2 in a ratio of the former/the latter.

The formation reaction of the linker may be carried out in the presence of a solvent. The solvent is not particularly limited to a specific one as far as the solvent is inactive to the reaction. The solvent may suitably be selected depending on the species of the raw material compounds (7-a) to (7-d), the species of the reaction, and others and may include, for example, a hydrocarbon (e.g., an aliphatic hydrocarbon such as pentane or hexane; an alicyclic hydrocarbon such as cyclohexane; and an aromatic hydrocarbon such as benzene, toluene, or xylene), a halogen-containing solvent (e.g., a halogenated hydrocarbon such as methylene chloride, chloroform, carbon tetrachloride, bromoform, or ethylene chloride), an alcohol (e.g., an alkanol such as methanol, ethanol, propanol, isopropanol, butanol, isobutanol, or t-butanol; and a glycol such as ethylene glycol or propylene glycol), an ether (e.g., a chain ether such as ethyl ether or isopropyl ether; and a cyclic ether such as dioxane, tetrahydrofuran, or tetrahydropyran), a cellosolve (e.g., a C_1-4alkyl cellosolve such as methyl cellosolve or ethyl cellosolve), a cellosolve acetate (e.g., a C_1-4alkyl cellosolve acetate such as ethyl cellosolve acetate), a carbitol (e.g., methyl carbitol), a ketone (e.g., a dialkyl ketone such as acetone, methyl ethyl ketone, diisopropyl ketone, or isobutyl methyl ketone), an organic carboxylic acid (e.g., acetic acid), an ester (e.g., an acetic acid ester such as methyl acetate, ethyl acetate, butyl acetate), an amide (e.g., formamide; an N-mono- or di-C_1-4alkylformamide such as N-methylformamide or N,N-dimethylformamide; and an N-mono- or di-C_1-4alkylacetamide such as N-methylacetamide or N,N-dimethylacetamide), a pyridine (e.g., pyridine and pyridine borane), and a nitrile (e.g., acetonitrile and benzonitrile). These solvents may be used alone or as a mixed solvent.

Moreover, the formation reaction of the linker may be carried out in the presence of a catalyst. The catalyst may include, for example, an acid catalyst [for example, an inorganic acid (e.g., sulfuric acid), an organic acid (e.g., p-toluenesulfonic acid), and Lewis acid], a base catalyst {for example, an inorganic base [e.g., a metal hydroxide (e.g., an alkali metal or alkaline earth metal hydroxide such as sodium hydroxide) and a metal carbonate (e.g., an alkali metal or alkaline earth metal carbonate such as sodium carbonate)], an organic base [for example, an aliphatic amine [for example, a primary to tertiary aliphatic amine, e.g., an aliphatic tertiary amine such as a triC_1-4alkylamine (such as triethylamine, diethylmethylamine, diisopropylethylamine, tri-n-propylamine, or tributylamine)], an aromatic amine (for example, a primary to tertiary aromatic amine, e.g., an aromatic tertiary amine such as N,N-dimethylaniline), and a heterocyclic amine (for example, a primary to tertiary heterocyclic amine, e.g., a heterocyclic tertiary amine such as picoline, pyridine, pyrazine, pyrimidine, pyridazine, 1-methylimidazole, triethylenediamine, N,N-dimethylaminopyridine, or 1,8-diazabicyclo[5.4.0]unde-7-cene)]}. These catalysts may be used alone or in combination.

The amount of the catalyst may for example be about 0.0001 to 5 mol and preferably about 0.001 to 1 mol relative to 1 mol of the compound (7-a) [or the compound (7-c)] or the compound (7-b) [or the compound (7-d)].

The formation reaction of the linker may be conducted under a room temperature or a heated condition. Moreover, the reaction can be conducted in air or under an inactive (or inert) gas atmosphere (such as nitrogen, helium, or argon gas). The reaction may be carried out under an atmospheric pressure or an applied pressure. The reaction time is not particularly limited to a specific one and may for example be about 0.1 to 60 hours and preferably about 0.5 to 50 hours.

After the completion of the reaction, the compound represented by the formula (1) [or the formula (7-e)] or the salt thereof may be separated or purified from the reaction mixture by a conventional separation or purification (or isolation) method, for example, filtration, distillation, condensation, precipitation, crystallization, recrystallization, decantation, extraction, drying, washing, chromatography, and a combination thereof.

(Compound Represented by the Formula (7-a))

The compound represented by the formula (7-a) can be prepared according to a conventional method, for example, any one of the following reaction schemes (iii) to (v).

wherein A¹ represents the group A or a residue of the group A; the groups A² and A³ are located at an end of the compound having the group A¹ and an end of the compound having the ring B, respectively, and allow to react with each other to link the group A and the ring B; B¹ and B² are groups which allow to react with each other to form the ring B, B³ and B⁴ are groups which allow to react with each other to form the ring B; the group A, the ring B, the group L¹ and n have the same meanings as defined above.

In the reaction step (iii), the method for linking the group A to the ring B is not particularly limited to a specific one, and conventional addition reaction, substitution reaction, coupling reaction (for example, a cross-coupling reaction such as Suzuki coupling reaction), or other reactions can be used. As the combination of A² and A³, for example, when A² is a boronic acid group [—B(OH)₂] and A³ is a halogen atom, both groups allow to react with each other to link A¹ (=A) to the ring B, and the compound represented by the formula (7-a) is obtained.

The compound represented by the formula (8-a) may include a compound in which A² is a boronic acid group, for example, an arylboronic acid[e.g., a halo-alkoxyarylboronic acid (preferably a halo-C_1-6alkoxyC_6-10arylboronic acid) such as 4-chloro-2-methoxyphenylboronic acid].

The compound represented by the formula (8-b) may include a compound in which A³ is a halogen atom and L¹ is an alkoxycarbonyl group [e.g., an alkyl 4-halo-1-alkyl-1H-pyrrole-2-carboxylate (preferably a C_1-4alkyl 4-halo-1-C_1-4alkyl-1H-pyrrole-2-carboxylate) such as ethyl 4-bromo-1-methyl-1H-pyrrole-2-carboxylate], and others.

The ratio (amount to be used) of the compound represented by the formula (8-a) relative to the compound represented by the formula (8-b) may for example be about 99/1 to 1/99, preferably about 90/10 to 10/90, and more preferably about 85/15 to 15/85 in a molar ratio of the former/the latter.

The reaction of the compound (8-a) and the compound (8-b) may be carried out in the presence of an inorganic base. As the inorganic base, there may be mentioned a metal carbonate (for example, an alkali metal carbonate such as potassium carbonate or sodium carbonate), and others. These inorganic bases may be used alone or in combination. The ratio (the amount to be used) of the inorganic base may for example be about 0.1 to 10 mol and preferably about 0.5 to 5 mol relative to 1 mol of the total of the compound (8-a) and the compound (8-b).

The reaction of the compound (8-a) and the compound (8-b) may be carried out in the presence of a catalyst [for example, a palladium-series catalyst such as tetrakis(triphenyphosphine)palladium]. The ratio (the amount to be used) of the catalyst may be not more than 0.1 mol and preferably not more than 0.01 mol (e.g., about 0.001 to 0.01 mol) relative to 1 mol of the total of the compound represented by the formula (8-a) and the compound represented by the formula (8-b).

The reaction of the compound (8-a) and the compound (8-b) may be carried out in the presence of a solvent. The solvent is not particularly limited to a specific one as far as the solvent is inactive to the reaction. The solvent may include water, a hydrocarbon (e.g., an aliphatic hydrocarbon such as pentane or hexane; an alicyclic hydrocarbon such as cyclohexane; and an aromatic hydrocarbon such as benzene, toluene, or xylene), an amide (e.g., formamide; an N-mono- or di-C_1-4alkylformamide such as N-methylformamide or N,N-dimethylformamide; and an N-mono- or di-C_1-4alkylacetamide such as N-methylacetamide or N,N-dimethylacetamide), and others. These solvents may be used alone or as a mixed solvent. Among these solvents, mixed solvent of a water and an amide [for example, a mixed solvent containing water and an amide in a ratio (volume ratio) of 10/90 to 50/50 as the former/the latter] is widely used.

The reaction of the compound (8-a) and the compound (8-b) can be conducted under a room temperature or a heated condition. For example, the reaction can be conducted at a temperature of about 10 to 150° C. (preferably about 20 to 100° C.). Moreover, the reaction can be conducted in air or under an inactive (or inert) gas atmosphere (such as nitrogen, helium, or argon gas). The reaction may be carried out under an atmospheric pressure or an applied pressure. The reaction time is not particularly limited to a specific one and may for example be about 0.1 to 20 hours, preferably about 0.5 to 15 hours, and more preferably about 1 to 10 hours.

In the reaction step (iv), the method for forming the ring B is not particularly limited to a specific one and a known method for producing a heterocyclic ring [for example, a method described in the fourth edition Jikken Kagaku Koza (Experimental Chemistry Lecture) 24, Organic Chemistry VI, Hetero element/representative metal element compounds, edited by The Chemical Society of Japan, published by Maruzen Company, Limited, p. 463 to 549] can be used. For example, a reaction such as a reaction of a thioamide (or an amide, a ketone) and an α-halo ketone (e.g., Hantzsch method, Feist-Benary method), a reaction of a thiosemicarbazide (or a semicarbazide) and an acid halide, or a reaction of a hydroxyiminoacetonitrile and an alkyl thioglycolate can be used for cyclization. In the cyclization reaction, representative combination examples of the compound (8-c) and the compound (8-d) as well as representative examples of the compound (7-a) are shown in Table 6.

In the formulae of Table 6, Halo represents a halogen atom (such as a chlorine atom or a bromine atom); the group A, the group L¹ and n have the same meanings as defined above.

In the reaction step (v), the method for forming the ring B is not particularly limited to a specific one and a known method for producing a heterocyclic ring [for example, a method described in the fourth edition Jikken Kagaku Koza (Experimental Chemistry Lecture) 24, Organic Chemistry VI, Hetero element/representative metal element compounds, edited by The Chemical Society of Japan, published by Maruzen Company, Limited, p. 463 to 549] can be used. For example, a cyclization reaction of an α,β-unsaturated ketone (or a 1,2-diketone) and a hydrazine (or a hydroxylamine, an amide) can be used. In the cyclization reaction, representative combination examples of the compound (8-e) and the compound (8-f) as well as representative examples of the compound (7-a) are shown in Table 7.

The acid component may include an alkanoic acid (e.g., a C_1-6alkanoic acid) such as formic acid, acetic acid, or propionic acid, or an acid anhydride thereof. In the case where a nitrogen atom is introduced into the ring C², nitrous acid or a salt (an alkali metal salt such as a sodium salt) thereof or an ester thereof (e.g., a C_1-6alkyl ester of nitrous acid, such as isoamyl nitrite) is widely used in addition to the acid component.

In the formulae of Table 8, the group L² and the group Z have the same meanings as defined above.

In the cyclization reaction (vi), the ratio (the amount to be used) of the compound (9-a) relative to the compound (9-b) may be about 2/1 to 1/2 and preferably about 1.5/1 to 1/1.5 in a molar ratio of the former/the latter. Since the organic acid such as formic acid also act as a reaction solvent, the molar quantity of the compound (9-b) may be in excess of that of the compound (9-a) [for example, the ratio of the compound (9-a) relative to the compound (9-b) may be about 1/2 to 1/50 in a molar ratio of the compound (9-a)/the compound (9-b)].

In the cyclization reaction (vii), the intramolecular cyclization of the compound (9-c) in the presence of a peroxide (such as hydrogen peroxide solution) and an organic acid (such as formic acid) forms a 5-membered ring adjacent to both the benzene ring and the ring C³. The organic acid such as formic acid acts as a reactant and a reaction solvent; the molar quantity of the organic acid is usually in excess of that of the compound (9-c) [for example, the ratio of the compound (9-c) relative to the organic acid may be about 1/2 to 1/50 in a molar ratio of the compound (9-c)/the organic acid].

The cyclization reactions (vi) and (vii) may be carried out in the presence of a solvent. The solvent may include a hydrocarbon (e.g., an aliphatic hydrocarbon such as pentane or hexane; an alicyclic hydrocarbon such as cyclohexane; and an aromatic hydrocarbon such as benzene, toluene, or xylene), a halogen-containing solvent (e.g., a halogenated hydrocarbon such as methylene chloride, chloroform, carbon tetrachloride, bromoform, or ethylene chloride), and an ether (e.g., a chain ether such as ethyl ether or isopropyl ether; and a cyclic ether such as dioxane, tetrahydrofuran, or tetrahydropyran). These solvents may be used alone or as a mixed solvent.

The cyclization reactions (vi) and (vii) can be carried out under a room temperature or a heated condition. For example, the reaction can be conducted at a temperature of about 10 to 150° C. (preferably about 20 to 100° C.). Moreover, the reaction can be conducted in air or under an inactive (or inert) gas atmosphere (such as nitrogen, helium, or argon gas). The reaction may be carried out under an atmospheric pressure or an applied pressure. The reaction time is not particularly limited to a specific one and may for example be about 1 minute to 50 hours, preferably about 5 minutes to 40 hours, and more preferably about 10 minutes to 30 hours.

In the compound (7-a) [or the compound (7-c)] or the compound (7-b) [or the compound (7-d)], L¹ (the end group J) or L² (the end group K) may be groups which allow to directly react with each other to form a linker, or may be precursor groups of the groups which can form a linker. The precursor groups can be converted into an objective group by using a known reaction (such as an oxidation reaction, a reduction reaction, an addition reaction, a condensation reaction, a hydrolysis reaction, or a rearrangement reaction). For example, an alkoxycarbonyl group can be converted into a carboxyl group by a hydrolysis reaction; a carboxyl group can be (a) converted into an acid azide group by a reaction with a diarylphosphoryl azide, and the acid azide group can be converted into an isocyanate group by Curtius rearrangement reaction, (b) converted into a carbazoyl group by a reaction with hydrazine, (c) converted into a carbamoyl group by a reaction with ammonia, and the carbamoyl group can be converted into an isothiocyanato group by a reaction with thionyl chloride, or (d) converted into an aldehyde group by a reduction reaction, and the aldehyde group can be (d1) converted into an alkyl group by Clemmensen reduction, and the alkyl group can be converted into a haloalkyl group by halogenation or (d2) converted into an aminocyano group by a reaction with hydrazine.

The reaction for converting L¹ (the end group J) or L² (the end group K) into an objective group and the formation reaction of the linker L may be conducted in respective reaction systems or in the same reaction system.

Specifically, one example of the method for producing the linker represented by the formula (1-a) (a method using Curtius rearrangement) is explained in detail as follows. In this method, a compound represented by the formula (7-h) is obtained by a reaction of a carboxylic acid represented by the formula (7-f), an alcohol represented by the formula (7-g) and a diarylphosphoryl azide (a diC_6-10arylphosphoryl azide such as diphenylphosphoryl azide) in the presence of a base, according to the following reaction scheme:

wherein the group A, the ring B, the ring C, the group L^1a, the group L^2a, j, k and n have the same meanings as defined above. More specifically, a compound represented by the formula (7-h) is obtained according to the following reaction scheme:

wherein the group A, the ring B, the ring C, the group L^1a, the group L^2a, j, k and n have the same meanings as defined above.

That is, the compound represented by the formula (7-h) is obtained by a step for allowing the carboxylic acid represented by the formula (7-f) to react with the diarylphosphoryl azide in the presence of the base to produce a carboxylic acid azide, a step for converting an acid azide group of the carboxylic acid azide into an isocyanate group by Curtius rearrangement to produce an isocyanate represented by the formula (7-j), and a step for allowing the isocyanate to react with the alcohol represented by the formula (7-g).

The ratio (the amount to be used) of the carboxylic acid represented by the formula (7-f) relative to the alcohol represented by the formula (7-g) is not particularly limited to a specific one, and may be the ratio at which the carboxyl group and the hydroxyl group may be equivalent or almost equivalent. For example, the ratio of the carboxylic acid relative to the alcohol may be about 2/1 to 1/2, preferably about 1.5/1 to 1/1.5, and more preferably about 1.2/1 to 1/1.2 in a molar ratio of the former/the latter.

The ratio (the amount to be used) of the diarylphosphoryl azide may for example be about 0.1 to 2 mol, preferably about 0.5 to 1.5 mol, and more preferably 0.8 to 1.2 mol relative to 1 mol of the carboxylic acid represented by the formula (7-f).

The base may be a basic inorganic compound and is usually a basic organic compound. As the basic organic compound, a tertiary amine is widely used. For example, the basic organic compound may include an aliphatic amine (e.g., a triC_1-6alkylamine such as trimethylamine or triethylamine; and an N,N,N′,N′-tetraC_1-4alkylC_1-4alkanediamine such as N,N,N′,N′-tetramethylethylenediamine or N,N,N′,N′-tetramethylpropanediamine), an alicyclic amine (e.g., a triC_5-6cycloalkylamine such as tricyclohexylamine; a diC_5-6cycloalkylC_1-4alkylamine such as dicyclohexylethylamine; and a diC_1-4alkylC_5-6cycloalkylamine such as diethylcyclohexylamine), and an aromatic amine (e.g., an N,N-diC_1-4alkylaniline such as N,N-dimethylaniline or N,N-diethylaniline; and an N-arylpyrrolidine such as N-phenylpyrrolidine). These bases may be used alone or in combination. Among these bases, a triC_1-4alkylamine such as triethylamine is widely used.

The ratio (the amount to be used) of the base is, for example, about 0.01 to 1 mol and preferably about 0.1 to 0.5 mol relative to 1 mol of the total of the carboxylic acid represented by the formula (7-f), the alcohol represented by the formula (7-g) and the diarylphosphoryl azide.

The reaction of the compound (7-f) and the compound (7-g) may be carried out in the presence of a solvent. The is not particularly limited to a specific one as far as the solvent is inactive to the reaction. The solvent may include a hydrocarbon (e.g., an aliphatic hydrocarbon such as pentane or hexane; an alicyclic hydrocarbon such as cyclohexane; and an aromatic hydrocarbon such as benzene, toluene, or xylene), a halogen-containing solvent (e.g., a halogenated hydrocarbon such as methylene chloride, chloroform, carbon tetrachloride, bromoform, or ethylene chloride), an ether (e.g., a chain ether such as ethyl ether or isopropyl ether; and a cyclic ether such as dioxane, tetrahydrofuran, or tetrahydropyran), a ketone (e.g., a dialkyl ketone such as acetone, methyl ethyl ketone, diisopropyl ketone, or isobutyl methyl ketone), an ester (e.g., an ester of acetic acid, such as methyl acetate, ethyl acetate, or butyl acetate), and a nitrile (e.g., acetonitrile). These solvents may be used alone or as a mixed solvent. Among these solvents, an aromatic hydrocarbon such as toluene is widely used.

The reaction of the compound (7-f) and the compound (7-g) can be conducted under a room temperature or a heated condition. For example, the reaction can be conducted at a temperature of about 10 to 150° C. (preferably about 20 to 100° C.). Moreover, the reaction can be conducted in air or under an inactive (or inert) gas atmosphere (such as nitrogen, helium, or argon gas). The reaction may be carried out under an atmospheric pressure or an applied pressure. The reaction time is not particularly limited to a specific one and may for example be about 0.1 to 20 hours, preferably about 0.5 to 15 hours, and more preferably about 1 to 10 hours.

After the completion of the reaction, the compound represented by the formula (7-h) or the salt thereof may be separated or purified from the reaction mixture by a conventional separation or purification (or isolation) method, for example, filtration, distillation, condensation, precipitation, crystallization, recrystallization, decantation, extraction, drying, washing, chromatography, and a combination thereof.

Step 8-1-1

Ethyl 4-(2,4-dichlorophenyl)-2,4-dioxobutyrate

A 20% sodium ethoxide-ethanol solution (17 g) was added to tetrahydrofuran (100 ml), and the mixture was cooled to 0° C. It took 60 minutes to dropwise add a solution of 2′,4′-dichloroacetophenone (9.45 g) and diethyl oxalate (7.30 g) in tetrahydrofuran (100 ml) to the mixture. After the completion of the dropping, the mixture was allowed to warm to a room temperature and stirred for 2 hours. To the mixture, 2-N hydrochloric acid (200 ml) and chloroform (200 ml) were added. The organic layer was collected by separation and dried over anhydrous magnesium sulfate, and the solvent was distilled off. Thus, the title compound (11.3 g, 78%) as a light-brown oily substance was obtained. ¹H-NMR (DMSO-d₆) δ: 7.85-7.74 (m, 1H), 7.70-7.62 (m, 1H), 7.58-7.55 (m, 2H), 6.53 (brs, 1H), 4.29-4.21 (m, 2H), 1.29-1.25 (m, 3H)

[2-(4-Chloro-2-methoxyphenyl)-4-methylthiazol-5-yl]carbamic acid 1,2,3,4-tetrahydrobenzo[4,5]imidazo[1,2-a]pyridin-7-ylmethyl ester

In toluene (50 ml), 2-(4-chloro-2-methoxyphenyl)-4-methylthiazole-5-carboxylic acid (1.11 g, 3.91 mmol) prepared in Example 7-1 and (1,2,3,4-tetrahydrobenzo[4,5]imidazo[1,2-a]pyridin-7-yl)methanol (870 mg, 4.30 mmol) prepared in Example 3-1 were suspended. Triethylamine (475 mg, 4.69 mmol) and then diphenylphosphoryl azide (1.18 g, 4.30 mmol) were added to the suspension, and the mixture was heated under reflux for 2 hours. Chloroform was added to the mixture, and the resulting mixture was washed with a saturated sodium bicarbonate solution. The washed mixture was dried over anhydrous magnesium sulfate and then concentrated. The concentrate was purified by silica gel column chromatography (chloroform:methanol=10:1) to give the title compound (1.34 g, 71%) as a white powder.

1-(4-Bromo-1-methyl-1H-pyrrol-2-yl)-2,2,2-trichloroethanone

Under an ice cooling, N-methylpyrrole (8.10 g, 100 mmol) was dissolved in methylene chloride (100 ml), and trichloroacetyl chloride (20.00 g, 115 mmol) was added thereto. Thereafter, the mixture was stirred at a room temperature for 16 hours. A saturated sodium hydrogen carbonate aqueous solution was added to the mixture. The organic phase was collected by separation, washed with water, and dried over anhydrous magnesium sulfate. The solvent was distilled off. Thus, 2,2,2-trichloro-1-(methyl-1H-pyrrol-2-yl)ethanone (16.3 g, 72%) was obtained. The resulting 2,2,2-trichloro-1-(methyl-1H-pyrrol-2-yl)ethanone (15.0 g, 66.7 mmol) was dissolved in chloroform (150 ml), and N-bromosuccinimide (12.5 g, 70.2 mmol) was added thereto at a room temperature. The mixture was heated under reflux for 16 hours. After the mixture was allowed to cool, a saturated sodium hydrogen carbonate aqueous solution was added to the mixture. The organic phase was collected by separation, washed with water, and dried over anhydrous magnesium sulfate. The solvent was distilled off. The resulting residue was purified by silica gel column chromatography (ethyl acetate:n-hexane=1:9) to give the title compound (14.0 g, 69%).

Example 12-1

Step 12-1

[2-(4-Chloro-2-methoxyphenyl)-4-methylthiazol-5-yl]methanol

Lithium aluminum hydride (380 mg, 10.0 mmol) was suspended in tetrahydrofuran (10 ml), and a suspension (10 ml) of 2-(4-chloro-2-methoxyphenyl)-4-methylthiazole-5-carboxylic acid (1.42 g, 5.00 mmol) prepared in Example 7-1 in tetrahydrofuran was added thereto at a room temperature. The mixture was stirred for 3 hours at a room temperature. Under an ice cooling, 5 drops of a saturated sodium bicarbonate solution were slowly added to the mixture. Ethyl acetate was added to the mixture, and another 5 drops of a saturated sodium bicarbonate solution were added thereto. The precipitate was removed by filtration, and the removed solid was washed with chloroform. The washings and the filtrate were concentrated together. The concentrate was purified by silica gel column chromatography (chloroform:methanol=20:1) to give the title compound (580 mg, 43%) as a light-brown powder.

Measurement of Cell Death-Inducing Activity

The cell death-inducing activity of the compound represented by the formula (1) or the salt thereof was measured as follows.

Human prostate cancer cell lines (PC-3 cells) were seeded to 6-well plates at 1×10⁵ cells/2 mL/well, and cultured in the presence of 5% CO₂ at 37° C. for 48 hours. Thereafter, each compound was added thereto so as to provide 10, 1, 0.1, 0.025 and 0.00625 μmol/L. As a control, DMSO was added. After the addition, the cells were continuously cultured for 48 hours. Then, typical 10 fields were observed in each well to qualitatively evaluate the cell death-inducing rate. When the cell death-inducing rate was not less than 40%, the compound was judged to have the cell death-inducing activity.

Test Example 2

Calculation of IC₅₀ Value

Human prostate cancer cell lines (PC-3 cells) and human fibrosarcoma cell lines (HT1080 cells) were seeded to 96-well microplates so as to provide a density of 1,300 cells/well and that of 3,100 cells/well, respectively. In the presence of 5% CO₂ at 37° C., the PC-3 cells and the HT1080 cells were cultured for 48 hours and 24 hours, respectively. Thereafter, each one of test substances was added to each well. As a control of a medical agent, DMSO was added. After the addition, both cells were continuously cultured for 72 hours. Then, an XTT labeling reagent containing 1 mg/mL of sodium 3′-[1-(phenylaminocarbonyl)-3,4-tetrazolium]-bis(4-methoxy-6-nitro)benzenesulfonate hydrate (XTT) and an electronic coupling reagent containing 1.25 mM N-methyl dibenzopyrazine methyl sulfate (PMS) were mixed at a ratio of 50:1 to give an XTT labeling mixture. The XTT labeling mixture was added to each well in an amount of 50 μL per well, and the cells were cultured for another 4 hours. A culture solution containing a test substance was used as a blank, and the absorbencies of a culture solution containing the XTT labeling mixture at a measurement wavelength (450 nm) and a control wavelength (650 nm) were measured by a plate reader. The difference between these absorbencies was evaluated as an activity of dehydrogenase of mitochondria derived from living cells. With respect to the following model formula of sigmoid curve, the convergent solution of each variable (gain, range, base and α) that minimize the residual sum of squares of the difference between these absorbencies and regressive prediction was determined, and then IC₅₀ (=e^α) of each test substance was calculated.

$\mathrm{Difference}\mathrm{between}\mathrm{absorbencies}=\frac{\mathrm{range}}{1+{}^{\mathrm{gain}\left(ln\left(\mathrm{Test}\mathrm{substance}\mathrm{concentration}\right)-\alpha \right)}}+\mathrm{base}$

Test Example 3

Measurement of Expression Kinetics of p27^Kip1 and Other Substrate Proteins

The possibility that p21^Cip1, p57^Kip2 and CyclinD1 are substrate proteins of SCF^Skp2 has been reported. While, there is also a report that gives a suggestion that these proteins may be substrates of another E3. The following suggestions about Nrf2 have been given: the progressive expression of Nrf2 is an index of the acquirement of resistance by an existing drug (anticancer agent), and Nrf2 is a substrate protein of another E3. Thus, in order to verify that the compounds represented by the formula (1) or the salts thereof are p27^Kip1-selective degradation inhibitors, these molecules in addition to p27^Kip1 were used as objects of analysis.

PC-3 cells in logarithmic growth phase (48 hours after seeding) were treated with 10 to 25 nmol/L of each test substance, then the cells were collected with time, and the protein was extracted and determined quantitatively. The protein groups contained in each extract (the amount of protein: 10 to 15 μg) were separated by polyacrylamide gel electrophoresis and then transferred to a PVDF (polyvinylidene difluoride) membrane. The proteins in the membrane were allowed to react with various primary antibodies to p27^Kip1, p21^Cip1, p57^Kip2, CyclinD1, Nrf2 and β-actin at a room temperature for about 2 hours, then allowed to further react with a biotinylated secondary antibody at a room temperature for one hour, and then allowed to react with streptavidin alkaline phosphatase at a room temperature for 30 minutes. As the final step, the proteins in the membrane were detected by allowing to react with a chemiluminescent substrate containing disodium 4-chloro-3-(methoxyspiro{1,2-dioxetadioxetane-3,2′-(5′-chloro)tricyclo[3.3.1.1^3,7]decan}-4-yl)phenylphosphate.

Results

As apparent from FIG. 1 to FIG. 3, the compounds represented by the formula (1) or the salts thereof increased only the expression amount of p27^Kip1 with time without affecting the expression amounts of other analyzed substrate proteins.

Test Example 4

Analysis of Cell Death-Inducing Action

Human prostate cancer cell lines (PC-3 cells) in logarithmic growth phase (48 hours after seeding) were treated with the compound represented by the formula (1) or the salt thereof, then the cells were collected with time and suspended in 70% ethanol. Thereafter, the cells in the suspension were allowed to stand at −20° C. overnight or more to be immobilized. The immobilized cells were washed with PBS twice, 100 μL of 192 mmol/L of disodium hydrogen phosphate and 4 mmol/L of a citric acid solution were added thereto, and the cells were suspended. The resulting suspension was gently stirred at a room temperature for 30 minutes. After centrifugation, the supernatant was removed. Then, 100 μL of a 100 μg/mL RNase/PBS solution was added to the residue, and the residue was suspended. The resulting suspension was incubated at 37° C. for 30 minutes. To the suspension, 850 μL of PBS was added, and then 50 μL of a 1 mg/mL propidium iodide/PBS solution were added thereto. The reaction was conducted at a room temperature for 30 minutes while gently stirring the mixture by inverting, and then the reaction mixture was filtered through a mesh filter to give an analysis sample. Using a flow cytometer, the ratio of sub-G₁ cells*, as an index of apoptosis cells, was analyzed. *Darzynkiewicz Z, et al. Cytometry, 27: 1-20, (1997) (This paper defines that the sub-G₁ cell is an index of an apoptosis cell.)

Results

As apparent from FIG. 1 to FIG. 6, the results suggest that the compounds represented by the formula (1) or the salts thereof selectively increase the expression amount of p27^Kip1 and then induce apoptosis.
