Definitions
- the present invention relates to general formula (I) (Wherein all symbols have the same meaning as described below), a salt thereof, a solvate thereof, an N-oxide thereof, or a prodrug thereof (hereinafter abbreviated as a compound of the present invention). There is.)
- Sphingosine-1-phosphate [(2S, 3R, 4E) -2-amino-3-hydroxyoctadec-4-enyl-1-phosphate; hereinafter abbreviated as S1P. ] Is a lipid synthesized by intracellular sphingolipid turnover and extracellular sphingosine kinase action, and has been proposed to act as an intercellular signal transmitter and intracellular secondary signal transmitter. ing.
- the S1P 5 (EDG-8) receptor is known to be highly expressed in oligodendrocytes (oligodendrocytes) and oligodendrocyte progenitor cells, and the S1P 5 receptor It has been revealed that activation of oligodendrocyte progenitor cells promotes differentiation induction into oligodendrocytes (see Non-Patent Documents 1 and 2). Oligodendrocytes are a type of glial cell that binds to nerve cell axons to form myelin sheaths (myelin). Therefore, a compound having the agonistic activity of the S1P 5 receptor promotes the regeneration of myelin (demyelination) that has disappeared in nerve cells, and thus is considered useful for the treatment of neurodegenerative diseases such as schizophrenia. ing.
- Non-Patent Document 3 See SlP 5 receptor in natural killer (NK) cells are known to be highly expressed, by activation of SlP 5 receptor, migration of NK cells are induced. Further, SlP 5 receptor, since it is involved in tumor immunity is highly expressed in known Patrolling monocyte, by activation of SlP 5 receptor, possibly tumor immune activation is induced.
- the dihydronaphthalene compound having S1P receptor binding ability is represented by the general formula (a) (Wherein ring A a represents a cyclic group, Ring B a further represents a cyclic group which may have a substituent group, X a represents a spacer bond or a main chain of 1 to 8 atoms Y a represents a bond or a spacer having 1 to 10 atoms in the main chain, na represents 0 or 1, when na is 0, ma represents 1 and R 1a represents a hydrogen atom or a substituent.

- R 1a represents a substituent (a plurality of R 1a may be the same or different when ma is 2 or more).
- the definition of each group was excised), and it was disclosed that the compound represented by ( 2 ) specifically binds specifically to the EDG-1 (S1P 1 ) and EDG-6 (S1P 4 ) receptors ( Patent Document 1).
- a compound represented by the general formula (b) (In the formula, ring A b represents a cyclic group, ring B b represents a cyclic group which may further have a substituent, and X b represents a bond or a spacer having 1 to 8 atoms in the main chain.
- Y b represents a bond or a main chain spacer of 1 to 10 atoms

- the linker from the phenyl group to the cyclic substituent has a short linker of 1 atom or less, and the compound of the present invention has an S1P 5 receptor agonistic activity for the S1P 1 receptor.
- An object of the present invention is to provide compounds with an improved balance of SlP 5 receptor agonist activity against S1P 1 receptor.
- the present inventors have intensively studied to find a compound that has improved the balance of S1P 5 receptor agonist activity with respect to the S1P 1 receptor.
- the compound has a dihydronaphthalene skeleton.
- by introducing a short linker of 1 atom or less as a linker from the phenyl group to the cyclic substituent it has been found that the balance of the S1P 5 receptor agonist activity with respect to the S1P 1 receptor is remarkably improved. Was completed.
