Full Text	1 DESCRIPTION IVDOLE COMPOUND AND USE THEREOF Technical Field The present invention relates to an indole compound which is useful as a medicament More specifically, the present invention relates to: (1) a compound represented by the formula (I), wherein all symbols have the same meanings as defined below; (2) a pharmaceutical composition containing the compound represented by the formula (I); and (3) a method for the preparation of the compound represented by the formula (T). Background Art Bronchial asthma is a pathological symptom, in which airway is contracted by airway contraction and inflammation, causing paroxysmal cough, stridor, and breathing difficulty. The drugs for treatment of it include steroidal agents for inhalation, which have a strong antiinflammatory effect, P stimulants and theophyllines which are bronchodilating agents, antiallergic agents which inhibit the effect of chemical mediators, etc. Histamine, leukotrienes, prostaglandins, TNF-, etc. are known as various chemical mediators which are released from mast cells or basophils which are concerned in bronchial asthma. Among leukotrienes (LTs), cysteinyl leukotrienes (abbreviated cysLTs hereinafter) represented by LTC4, LTD4 and LTE4 have approximately 1000 times stronger contractile effect on airway as compared to histamine. Moreover, cysLTs promote induction of airway inflammation, typically inflammation cell invasion, airway hypersensitivity and mucus secretion in airway, and they are deeply involved in basic pathology of bronchial asthma. The leukotriene receptor antagonists which are clinically used, e.g. pranlukast hydrate represented by the formula (A) (See Patent Document 1), montelukast sodium represented by the formula (B) (See Patent Document 2) and zafirlukast represented by the formula (C) (See Patent Document 3) are widely used as useful agents for the treatment of bronchial asthma and allergic rhinitis, which improves various kinds of symptoms and respiratory functions. 2 However, it is known these leukotriene receptor antagonists are more effective for mild or moderate symptoms than for severe symptoms. It is also known that there exist some non-responders with mild or moderate symptoms on whom the pharmaceutical agent does not have effect. So agents having higher efficacy than the existing agents have been desired. Pranlukast hydrate has a strong antagonistic activity against leukotriene receptor, but it also has problems of physical property and systemic absorption. It is known that a compound represented by the formula (D) wherein all symbols have the same meanings as described in the document, has an antagonistic activity against cysLT2 receptor. Pranlukast hydrate which is a leukotriene antagonist is useful for sinusitis (See Patent Document 5), headache such as migraine, migrainous neuralgia or tension-type headache (See Patent Document 6), endometriosis (See Patent Document 7), dysmenorrhea (See Patent Document 8), Meniere's disease, etc. Patent Document 1: Japan Patent No. 1741466 Patent Document 2: Japan Patent No.2501385 Patent Document 3: Japan Patent No.1955810 Patent Document 4: WO2000/18399 3 Patent Document 5: JP-A-2004-168718 Patent Document 6: JP-A-2002-187855 Patent Document 7: WO2005/058878 Disclosure Of The Invention Problems To Be Solved By The Invention As described hereinbefore, the leukotriene receptor antagonists which are clinically used are known to act on mild and moderate symptoms of bronchial asthma and it is also known that there exist some non-responders among patients with mild and moderate symptoms, to whom the agents are not effective. Therefore, it has been desired to find a leukotriene receptor antagonist which has stronger activity than that of the existing agents, and those agents for respiratory diseases showing higher efficacy than the existing agents have been desired. And since the indole compound described in patent document 4 has a week antagonistic activity against leukotriene receptor, it is not sufficiently effective when administered orally, so it was desired the improvement to be drug.

Biological Example 1: Effect on OVA-induced bronchocontraction involved in endogenous leukotriene in guinea pigs Guinea pigs were actively sensitized by intraperitoneal administration of lml of saline containing lmg ovalbumin (OVA) containing 5x109 killed Bordetellapertussis cells. Two or three weeks after the sensitization, the guinea pigs were anesthetized with pentobarbital sodium (75 mg/kg, i.p.), and a polyethylene tube was inserted into the trachea which had been incised. For administration of the compound of the present invention and OVA, the jugular vein was cannulated. One side of the tracheal cannula was connected to a constant volume respirator and the animals were artificially ventilated with a contsant volume of 5 mL at a frequency of 70 strokes/min. Bronchocontraction was induced by intravenous administration of OVA, and airway resistance was measured by Konzett & Rossler method. In order to avoid the influence of cyclooxygenase metabolites and histamine, indomethacin (5 mg/kg/mL) and pyrilamine (1 mg/kg/mL) were intravenously administered 3 and 1 minute(s) before OVA challenge. Bronchocontraction was measured until the time of 20 minutes after OVA challenge. It was revealed from the results that the compound represented by the formula (I) inhibited the contraction of guinea pig tracheal mustle.

DESCRIPTION
IVDOLE COMPOUND AND USE THEREOF
Technical Field
The present invention relates to an indole compound which is useful as a medicament
More specifically, the present invention relates to:
(1) a compound represented by the formula (I),
wherein all symbols have the same meanings as defined below;
(2) a pharmaceutical composition containing the compound represented by the formula (I); and
(3) a method for the preparation of the compound represented by the formula (T).
Background Art
Bronchial asthma is a pathological symptom, in which airway is contracted by airway contraction and
inflammation, causing paroxysmal cough, stridor, and breathing difficulty. The drugs for treatment of it include
steroidal agents for inhalation, which have a strong antiinflammatory effect, P stimulants and theophyllines which
are bronchodilating agents, antiallergic agents which inhibit the effect of chemical mediators, etc.
Histamine, leukotrienes, prostaglandins, TNF-, etc. are known as various chemical mediators which are
released from mast cells or basophils which are concerned in bronchial asthma. Among leukotrienes (LTs),
cysteinyl leukotrienes (abbreviated cysLTs hereinafter) represented by LTC4, LTD4 and LTE4 have approximately
1000 times stronger contractile effect on airway as compared to histamine. Moreover, cysLTs promote induction
of airway inflammation, typically inflammation cell invasion, airway hypersensitivity and mucus secretion in
airway, and they are deeply involved in basic pathology of bronchial asthma.
The leukotriene receptor antagonists which are clinically used, e.g. pranlukast hydrate represented by the
formula (A) (See Patent Document 1), montelukast sodium represented by the formula (B) (See Patent Document
2) and zafirlukast represented by the formula (C) (See Patent Document 3) are widely used as useful agents for the
treatment of bronchial asthma and allergic rhinitis, which improves various kinds of symptoms and respiratory
functions.

However, it is known these leukotriene receptor antagonists are more effective for mild or moderate
symptoms than for severe symptoms. It is also known that there exist some non-responders with mild or
moderate symptoms on whom the pharmaceutical agent does not have effect. So agents having higher efficacy
than the existing agents have been desired.
Pranlukast hydrate has a strong antagonistic activity against leukotriene receptor, but it also has problems of
physical property and systemic absorption.
It is known that a compound represented by the formula (D)
wherein all symbols have the same meanings as described in the document,
has an antagonistic activity against cysLT2 receptor.
Pranlukast hydrate which is a leukotriene antagonist is useful for sinusitis (See Patent Document 5),
headache such as migraine, migrainous neuralgia or tension-type headache (See Patent Document 6),
endometriosis (See Patent Document 7), dysmenorrhea (See Patent Document 8), Meniere's disease, etc.

Disclosure Of The Invention
Problems To Be Solved By The Invention
As described hereinbefore, the leukotriene receptor antagonists which are clinically used are known to act
on mild and moderate symptoms of bronchial asthma and it is also known that there exist some non-responders
among patients with mild and moderate symptoms, to whom the agents are not effective. Therefore, it has been
desired to find a leukotriene receptor antagonist which has stronger activity than that of the existing agents, and
those agents for respiratory diseases showing higher efficacy than the existing agents have been desired. And
since the indole compound described in patent document 4 has a week antagonistic activity against leukotriene
receptor, it is not sufficiently effective when administered orally, so it was desired the improvement to be drug.

The compound of the present invention represented by the formula (I) may be prepared by known methods,
for example, a method combining the following methods, the method according to these method, the methods
described in Examples and/or methods described in Comprehensive Organic Transformations: A Guide to
Functional Group Preparations, 2nd Edition (Richard C. Larock, John Wiley & Sons Inc, 1999), etc., which are
appropriately modified In each following method for the preparation, salts of the starting materials may be used.
The below-mentioned salts of the compound (I) can be used as the salts.
1) Among the compound of the present invention represented by the formula (I), a compound wherein

may be prepared by subjecting a compound represented by the formula (II)
wherein RI0A-1 represents carboxy which is protected, or 5-tetrazolyl, RJ"\ D1, R5"1, R1H and R12"1 have the
same meanings of R3, D, R5, R11 and R12, and when carboxy, hydroxy, amino or mercapto group exists in
the group, it is protected if the protection is necessary,
to a amidation with a carboxylic acid represented by the formula (IH-1)
wherein E1-1 has the same meaning of E1, and when carboxy, hydroxy, amino or mercapto group
exists in the group, it is protected if the protection is necessary, RQ represents a protective group of carboxy,
optionally foiiowed by subjecting to a deprotection reaction of the protective groups of RQ, followed by a
deprotection reaction of a protective group of carboxy, hydroxy, amino, mercapto or telrazolyl group, if necessary.
The amidation reaction may be carried out by, for example, (1) a method using acid halide, (2) a method

77
using mixed anhydride, (3) a method using a condensing agent, etc.
To explain these methods specifically;
(1) The method using acid halide is carried out, for example, by subjecting a carboxylic acid to a reaction with
an acid-halogenating agent {e.g. oxalyl chloride, thionyl chloride, etc.) in an organic solvent (e.g. chloroform,
dichloromethane, diethyl ether, tetrahydrofuran, dimethoxyethane, etc.) or without a solvent, at a temperature of-
20°C to a refluxing temperature, and then subjecting the thus obtained acid halide to a reaction with an amine in
the presence of a base (e.g. pyridine, triethylamine, dimethylaniline, dimethylaminopyridine,
diisopropylethylamine, etc.) in an organic solvent (e.g. chloroform, dichloromethane, diethyl ether, tetrahydrofuran,
acetonitorile, ethyl acetate, etc.) at a temperature of 0 to 40°C. Also, the reaction may be carried out by
subjecting the thus obtained acidic halide to a reaction with an amine in an organic solvent (e.g. dioxane,
tetrahydrofuran, dichloromethane, etc.) using an alkali aqueous solution (e.g. an aqueous solution of sodium
bicarbonate, sodium hydroxide, etc.) in the presence or absence of a phase-transfer catalyst (e.g. quaternary
ammonium salts such as tetrabutylammonium chloride, triethylberizylamrnonium chloride, tri-n-
octyrmethylammonium chloride, trimethyldecylammonium chloride, tetramethylammonium bromide, etc.) at a
temperature of between 0 to 40°C;
(2) The method using mixed anhydride is carried out, for example, by subjecting a carboxylic acid to a reaction
with an acid halide (e.g. pivaloyl chloride, tosyl chloride, mesyl chloride, etc.) or an acid derivative (e.g.ethyl
chloroformate, isobutyl chloroformate, etc.) in an organic solvent (e.g. chloroform, dichloromethane, diethyl ether,
tetrahydrofuran, etc.) or without a solvent in the presence of a base (pyridine, triethylamine, dimethylaniline,
dimethylaminopyridine, diisopropylethylamine, etc.) at a temperature of 0 to 40°C, and then subjecting the thus
obtained mixed anhydride to a reaction with an amine in an organic solvent (e.g. chloroform, dichloromethane,
diethyl ether, tetrahydrofuran, etc.) at a temperature of 0 to 40°C;
(3) The method using a condensing agent is carried out, for example, by subjecting a carboxylic acid to a
reaction with an amine in an organic solvent (e.g. chloroform, dichloromethane, N,N-dimethylformamide, diethyl
ether, tetrahydrofuran, etc.) or without a solvent, in the presence or absence of a base (e.g. pyridine, triethylamine,
dimethylaniline, dimethylaminopyridine, etc.), using a condensing agent (e.g. 1,3-dicyclohexylcarbodiimide
(DCC), l-ethyl-3-[3-(dimethylamino)propyl]carbodiimide(EDC), l,r-carbonyldiimidazole(CDI),2-chloro-l-
methylpyridinium iodide, 1-propylphosphonic acid cyclic anhydride (1-propanephosphonic acid cyclic anhydride;
PPA), etc.) in the presence or absence of 1-hydroxybenzotriazole (1-HOBt) at a temperature of 0 to 40°C.
The reactions of (1), (2) and (3) are desirably carried out under atmosphere of inert gas (argon, nitrogen,
etc.) and anhydrous conditions.
The deprotective reaction of RQ is known, and for example, when RQ is methyl or ehtyl, it may be carried
out by deprotection reaction by alkali hydrolysis, and when RQ is tert-butyl, it may be carried out by deprotection
reaction under acidic conditions.
The deprotection reaction by alkali hydrolysis is carried out, for example, in an organic solvent (methanol,
tetrahydrofuran, 1,4-dioxane, etc.) using a hydroxide of alkali metals (sodium hydroxide, potassium hydroxide,
lithium hydroxide, etc.), hydroxide of alkaline earth metals (barium hydroxide, calcium hydroxide, etc.), carbonate
(sodium carbonate, potassium carbonate, etc.) or a solution thereof or a mixture thereof at a temperature of 0 to
40°C.
The deprotection reaction under acidic conditions is carried out, for example, in an organic solvent
(dichloromethane, chloroform, dioxane, ethyl acetate, anisole, etc.), in an organic acid (acetic acid, trifluoroacetic
acid, methanesulfonic acid, p-toluenesulfonic acid, etc.) or an inorganic acid (hydrochloric acid, sulfuric acid, etc.)
or a mixture thereof (hydrobromic acid/acetic acid, etc.) in the presence or absence of 2,2,2-trifluoroethanol at a
temperature of 0 to 100°C.
The deprotection reaction of the protective groups of carboxy, hydroxy, amino, mercapto or tetrazolyl
group is well-known and includes, for example, (1) a deprotection reaction by alkali hydrolysis, (2) a deprotection

78
under acidic conditions, (3) a deprotection reaction by hydrogenolysis, (4) a deprotection reaction of silyl group,
(5) a deprotection reaction using a metal, (6) a deprotection reaction using a metal complex, etc.
To explain these methods concretely, (1) a deprotection reaction by alkali hydrolysis and (2) a deprotection
under acidic conditions can be performed in accordance with the method as described above.
(3) The deprotection reaction by hydrogenolysis is, for example, carried out in a solvent {e.g. ethers such as
tetrahydrofuran, 1,4-dioxane, dimethoxyethane, diethyl ether, etc.; alcohols such as methanol, ethanol, etc.;
benzenes such as benzene, toluene, etc.; ketones such as acetone, methyl ethyl ketone, etc; nitriles such as
acetonitrile etc.; amides such as N,N-dimethylforrnamide, N,N-dimethylacetamide etc.; water, ethyl acetate, acetic
acid or a mixture of two or more thereof, etc.) in the presence of a catalyst (palladium-carbon, palladium black,
palladium hydroxide, platinum oxide, Raney nickel, etc.) under the atmosphere of hydrogen of normal or
suppressed pressure, or in the presence of ammonium formate at a temperature of 0 to 200°C.
(4) The deprotection reaction of a silyl group is, for example, carried out in a water-miscible organic solvent
(tetrahydrofuran, acetonitrile, etc.) using tetrabutylammonium fluoride at a temperature of 0 to 40°C.
(5) The deprotection reaction using a metal is carried out, for example, in an acidic solvent (acetic acid, a buffer
of pH 4.2 to 7.2 or a mixture of the solution thereof and an organic solvent such as tetrahydrofuran etc.) in the
presence of zinc powder at a temperature of 0 to 40°C optionally under sonication.
(6) The deprotection reaction using a metal complex is carried out, for example, in an organic solvent
(dichloromethane, N,N-dimethylforrnarnide, tetrahydrofuran, ethyl acetate, acetonitrile, dioxane, ethanol, etc.),
water or a mixture thereof, in the presence of a trap reagent (iriburyltin hydride, triethylsilane, dimedone,
morpholine, diethylamine, pyrrolidine, etc.), an organic acid (acetic acid, formic acid, 2-ethylhexanecarboxylic
acid, etc.) and/or a salt of an organic acid (sodium 2-ethylhexanoate, potassium 2-ethylhexanoate, etc.) in the
presence or absence of a phosphine reagent (triphenylphosphine etc.) using a metal complex (palladium
tetrakis(triphenylphosphine (0)), palladium bis(triphenylphosphosphine) dichloride (II), palladium acetate (II),
rhodium tris(triphenylphosphine) chloride (I), etc. at a temperature of 0 to 40°C.
In addition to the above, deprotection reaction may be carried out by the method, for example, described in
T. W. Greene, Protective Groups in Organic Synthesis, Wiley, New York, 1999.

Biological Example 1: Effect on OVA-induced bronchocontraction involved in endogenous leukotriene in guinea
pigs
Guinea pigs were actively sensitized by intraperitoneal administration of lml of saline containing lmg
ovalbumin (OVA) containing 5x109 killed Bordetellapertussis cells. Two or three weeks after the sensitization,
the guinea pigs were anesthetized with pentobarbital sodium (75 mg/kg, i.p.), and a polyethylene tube was inserted
into the trachea which had been incised. For administration of the compound of the present invention and OVA,
the jugular vein was cannulated. One side of the tracheal cannula was connected to a constant volume respirator
and the animals were artificially ventilated with a contsant volume of 5 mL at a frequency of 70 strokes/min.
Bronchocontraction was induced by intravenous administration of OVA, and airway resistance was measured by
Konzett & Rossler method. In order to avoid the influence of cyclooxygenase metabolites and histamine,
indomethacin (5 mg/kg/mL) and pyrilamine (1 mg/kg/mL) were intravenously administered 3 and 1 minute(s)
before OVA challenge. Bronchocontraction was measured until the time of 20 minutes after OVA challenge.
It was revealed from the results that the compound represented by the formula (I) inhibited the contraction
of guinea pig tracheal mustle. For example, the compound of Example 44 inhibited the airway contraction at an
oral dose of 10 mg/kg.
