TECHNICAL FIELD
[0001] The present invention relates to a compound represented by general formula (I-1):

wherein, all the symbols have the same meanings as described below, or a pharmaceutically
acceptable salt thereof (hereinafter occasionally abbreviated as the compound of the
present invention).
BACKGROUND ART
[0002] Sphingosine-1-phosphate [(2S,3R,4E)-2-amino-3-hydroxyoctadec-4-enyl-1-phosphate;
hereinafter occasionally abbreviated as S1P] is a lipid which is synthesized by metabolic
turnover of sphingolipids in cells and by the extracellular action of a secreted sphingosine
kinase. It is proposed that sphingosine-1-phosphate acts as an intercellular communication
mediator as well as an intracellular second messenger.
[0003] Among S1P receptors, with regard to SIPs (EDG-8) receptor, it is known that S1P
5 (EDG-8) receptor is highly expressed in oligodendrocytes (oligodendroglia) and oligodendrocyte
progenitor cells (see Non Patent Literatures 1 and 2). Oligodendrocytes are a kind
of glial cells which form the myelin sheaths (myelin) by binding to the axons of nerve
cells. Accordingly, it is considered that a compound which has an S1P
5 receptor binding activity, and can mediate the function of an S1P
5 receptor, is useful for treating neurodegenerative disease such as schizophrenia
because the compound promotes the regeneration of myelin which has disappeared (demyelination)
in nerve cells.
[0004] In addition, it is known that S1P
5 receptor is highly expressed also in natural killer (NK) cells and it is revealed
that the migration of NK cells is induced by the activation of S1P
5 receptor (see Non Patent Literature 3).
[0005] Further, S1P
5 receptor is highly expressed in patrolling monocytes which are known to be involved
in the tumor immunity, and therefore, there is a possibility that the activation of
the tumor immunity is induced by the activation of S1P
5 receptor (see Non Patent Literatures 4 and 5).
[0006] Incidentally, as compounds of prior arts to the present invention, the following
compounds are known.
It is disclosed that a compound represented by general formula (a):

(wherein, X
a represents CH or N, R
1a represents a C3-6 cycloalkyl group which has a fluorine substituent(s), R
2a represents a hydrogen atom, a halogen atom, a cyano group or a trifluoromethyl group,
A
a represents a 5-membered heterocyclic ring which is chosen between thiazole, thiadiazole
or the like, B
a represents bicyclic ring which is chosen between a substituent as shown below;

(wherein, R
9a represents a C1-4 alkyl group which has at lease one hydroxy group substituent, R
10a represents a hydrogen atom or a C1-3 alkyl group which may be substituted with a
halogen atom) (provided that the definition of each of groups is excerpted)) has an
S1P
1 agonist activity (see Patent Literature 1).
[0007] Also, it is known that a compound represented by general formula (b):

(wherein, X
b represents C or N, R1
b represents H or an alkyl group which may have a substituent(s), R2
b represents H, an alkyl group which may have a substituent(s), a halogen atom or the
like, W
b represents C, N or a C-alkoxy group, Q
b represents CH
2O or the like, S
b represents a substituent as shown below;

(wherein, R3
b represents H, an alkyl group, a halogen atom or the like, nb represents 0 to 3) (provided
that the definition of each of groups is excerpted)) has an S1P agonist activity (see
Patent Literature 2).
Patent Literature 3 relates to the use of compounds described therein in the treatment
of amyloid-related diseases.
Patent Literature 4 relates to 2-aminotetralins and pharmaceutically acceptable acid
addition salts thereof, which are useful to treat central nervous system disorders,
hypertension, diabetes, sexual impotency and to control appetite.
Patent Literature 5 relates to substituted basic 2-aminotetralins and their use as
medicaments.
Patent Literature 6 relates to compounds effective in the treatment or prophylaxis
of HIV infection.
[0008] None of prior arts discloses or suggests that the compound of the present invention
has a selective S1P
5 binding activity and modulates the function of an S1P
5 receptor.

a solid agent for internal use or a solution for oral administration (internal use),
a sustained-release preparation in oral administration, or injectables, external preparations,
inhalants or suppositories for parenteral administration.
[0096] The solid preparations for oral administration (internal use) includs, for example,
tablets, pills, capsules, powders and granulars. The capsules include hard capsules
and soft capsules.
[0097] The oral solid preparation as an oral preparation is prepared, for example, by mixing
an active ingredient with an excipient (such as lactose, mannitol, glucose, microcrystalline
cellulose and starch), a bonding agent (such as hydroxypropyl cellulose, polyvinylpyrrolidone
and magnesium aluminometasilicate), a disintegrating agent (such as calcium cellulose
glycolate), a lubricant (such as magnesium stearate), a stabilizer, and a solubilizing

soft sugar, gelatin, hydroxypropyl cellulose and hydroxypropyl methylcellulose phthalate)
or may be coated with two or more layers. Further, capsules of substances which can
be absorbed, such as gelatin, are also included.
[0098] The liquid for oral administration (internal use) includes pharmaceutically acceptable
solutions, suspensions, emulsions, syrups and elixirs. In such the liquid formulations,
one or more active substances are dissolved, suspended or emulsified in diluents (e.g.
purified water, ethanol, or mixed liquids of them) which are generally used. Further,
this liquid formulation may contain wetting agents, suspending agents, emulsifiers,
sweeteners, flavors, fragrances, preservatives or buffers.
[0099] And, sustained-release preparations in oral administration are also effective. A
gel forming substance used in these sustained-release preparations is a substance
which is swollen while containing a solvent, thereby, mutually linking colloidal particles
thereof to have a three dimensional network structure, and can form a jelly-like body
which has no flowability. The substance is mainly used as binders, thickeners and
sustained-release bases from a view point of preparations. For example, gum arabic,
agar, polyvinyl pyrrolidone, sodium alginate, alginic acid propylene glycol ester,
carboxyvinyl polymer, carboxymethylcellulose, carboxymethylcellulose sodium, guar
gum, gelatin, hydroxypropylmethylcellulose, hydroxypropylcellulose, polyvinyl alcohol,
methylcellulose or hydroxyethylmethylcellulose can be used.
[0100] Injectables for parenteral administration include solutions, suspensions, emulsions
and solid injectables which are used by dissolving or suspending in a solvent upon
use. Injectables are used by dissolving, suspending or emulsifying one or more active
substances in a solvent. As the solvent, for example, distilled water for injection,
physiological saline, vegetable oil, alcohols such as propylene glycol, polyethylene
glycol, and ethanol, and a combination of them are used. Further, the injectables
may contain stabilizers, solubilization aids (e.g. glutamic acid, aspartic acid, Polysorbate
80 (registered trademark)), suspending agents, emulsifiers, soothing agents, buffers
or preservatives. These are produced by sterilization or a sterile operation method
at a final step. Alternatively, injectables can be also used as aseptic solid agents
(e.g. lyophilized products are produced, and dissolved in distilled water for injection
or other solvent which has been sterilized or are aseptic, before use thereof).
[0101] A dosage form of the external preparations for parenteral administration includes,
for example, spraying agents, inhalants, sprays, aerosols, ointments, gels, creams,
fomentations, patches, liniments and nose drops. These contain one or more active
substances, and prepared by the known method or formulation which is ordinarily used.
[0102] Spraying agents, inhalants and Sprays may contain stabilizers such as sodium hydrogen
sulfite and buffers imparting isotonicity, for example, isotonics such as sodium chloride,
sodium citrate or citric acid, in addition to diluents which are generally used. A
method of producing spraying agents is described in detail, for example, in
US Patents 2868691 and
3095355.
[0103] The inhalants for parenteral administration include aerosols, powders for inhalation
or solutions for inhalation, and the solutions for inhalation may be a form which
is used by dissolving or suspending in water or other suitable medium upon use.
[0104] These inhalants are produced in accordance with the known method.
[0105] For example, in the case of a solution for inhalation, it is prepared by appropriately
selecting antiseptics (e.g benzalkonium chloride, paraben), colorants, buffering agents
(e.g. sodium phosphate, sodium acetate), isotonizing agents (e.g. sodium chloride,
concentrated glycerin), thickeners (e.g. carboxyvinyl polymer), and absorption enhancers,

excipients (e.g. lactose, cellulose), colorants, antiseptics (e.g benzalkonium chloride,
paraben) or absorption enhancers, if necessary.
[0107] When solutions for inhalation are administered, usually, a sprayer (e.g. atomizer,
nebulizer) is used and, when powders for inhalation are administered, usually, an
inhalation administration equipment for powdery drugs is used.
[0108] Ointments are produced by formulation which is known or ordinarily used. For example,
ointments are prepared by kneading or melting one or more active substances into a
base. An ointment base is selected from ointment bases which are known or orginarily

(e.g. mink oil, yolk oil, squalane, squalene), water, absorption enhancers or rash
preventing agents are used alone, or by mixing two or more kinds. Further, ointment
bases may contain humectants, preservatives, stabilizers, antioxidants or flavoring
agents.
[0109] Gel agents are produced by formulation which is known or ordinarily used. For example,
gel agents are prepared by melting one or more active substances into a base. A gel
base is selected from gel bases which are known or ordinarily used. For example, gel

neutralizing agents (e.g. triethanolamine, diisopropanolamine), surfactants (e.g.
monostearic acid polyethylene glycol), gums, water, absorption enhancers and rash
preventing agents are used alone, or by mixing two or more kinds. Further, gel bases
may contain preservatives, antioxidants or flavoring agents.
[0110] Creams are prepared by formulation which is known or ordinarily used. For example,
creams are prepared by melting or emulsifying one or more active substances into a
base. A cream base is selected from cream bases which are known or ordinarily used.
For example, cream bases selected from higher fatty acid esters, lower alcohols, hydrocarbons,
polyhydric alcohols (e.g. propylene glycol, 1,3-butylene glycol), higher alcohols
(e.g. 2-hexyldecanol, cetanol), emulsifiers (e.g. polyoxyethylene alkyl ethers, fatty
acid esters), water, absorption enhancers and rash preventing agents are used alone,
or by mixing two or more kinds. Further, cream bases may contain preservatives, antioxidants
or flavoring agents.
[0111] Fomentations are produced by formulation which is known or ordinarily used. For example,
fomentations are produced by melting one or more active substances into a base, and
spreading a melt as a kneaded product on a support. A base used for fomentation is
selected from bases which are known or ordinarily used. For example, bases selected
from thickeners (e.g. polyacrylic acid, polyvinyl pyrrolidone, gum arabic, starch,
gelatin, methylcellulose), wetting agents (e.g. urea, glycerin, propylene glycol),
fillers (e.g. kaolin, zinc oxide, talc, calcium, magnesium), water, solubilization
aids, tackiness imparting agents and rash preventing agents are used alone, or by
mixing two or more kinds. Further, bases used for fomentations may contain preservatives,
antioxidants or flavoring agents.
[0112] Patches are produced by formulation which is known or ordinarily used. For example,
patches are produced by melting one or more active substances into a base, and spreading
a melt on a support. A base for patches is selected from bases for patches which are
known or ordinarily used. For example, bases for patches selected from polymer bases,
fats, oils, higher fatty acids, tackiness imparting agents and rash preventing agents
are used alone, or by mixing two or more kinds. Further, bases for patches may contain
preservatives, antioxidants or flavoring agents.
[0113] Liniments are produced by formulation which is known or ordinarily used. For example,
liniments are prepared by dissolving, suspending or emulsifying one or more active
substances in a base selected from water, alcohols (e.g. ethanol, polyethylene glycol),
higher fatty acid, glycerin, soaps, emulsifiers and suspending agents alone, or two
or more kinds of them. Further, liniments may contain preservatives, antioxidants
or flavoring agents.
[0114] Other composition for parenteral administration includes suppositories for rectal
administration or pessaries for intravaginal administration, which contain one or
more active substances, and are formulated by the conventional method.
[0115] In order to use the compound of the present invention or the combined medicine of
the compound of the present invention with other drug(s) for the above-described purpose,
the compound of the present invention or the combined medicine of the compound of
the present invention with other drug(s) is normally administered systemically or
locally, in the form of an oral preparation or a parenteral preparation. The dose
varies depending on the age, the body weight, the symptom, the therapeutic effect,
the method for administration, and the duration of the treatment. However, normally,
the dose per adult is in the range of from 1 ng to 1,000 mg per administration, from
one to several oral administrations per day or the dose per adult is in the rage of
from 0.1 ng to 10 mg per administration, from one to several parenteral administrations
per day. Alternatively, the dose is continuously administrated intravenously for a
period of time in the range of 1 to 24 hours per day. Of course, the dose varies depending
on various factors as described above, and therefore, there are some cases in which
a dose below the above-described dose is sufficient and there are other cases in which
administration of a dose which exceeds the above-described range is required.
