[0404] The compounds of formula (I) may have asymmetric centers, chiral axes and chiral planes.

[0405] The compounds of formula (I) may exist as racemates, as racemic mixtures and as individual diastereoisomers.

[0406] The compounds of formula (I) include all possible isomers, including optical isomers, and mixtures thereof.

[0407] The compounds of formula (I) may exist as tautomers. Even if only one tautomeric structure is described in the present specification, both tautomeric forms are included in the present invention.

[0408] The compounds of formula (I) include isotopomers in which one or more atoms within the molecule are replaced by their isotopes. In the present specification, an isotope means an atom having the same atomic number but a different mass number. Thus, "replaced by an isotope" in the present specification means replacement by an atom having the same atomic number but a different mass number from those normally present in nature.

[0409] For example, the hydrogen atoms constituting the compounds of formula (I) may be replaced by 2 H(D) or 3 H(T), and similarly, the carbon atoms constituting the compounds of formula (I) may be replaced by 11 C, 13 C or 14 C. Isotopomers replaced by stable isotopes such as 2 H(D) are useful because they sometimes exhibit therapeutic advantages due to higher metabolic stability. On the other hand, those replaced by 3 H(T), 14Isotopologues substituted with radioactive isotopes such as C are useful in the tissue distribution study of drugs and / or substrates. In addition, these isotopologues can be prepared by the methods disclosed in this specification or methods similar thereto using appropriate reagents containing the corresponding isotopes.

[0410] The "pharmaceutically acceptable salts" of the compounds of formula (I) are not particularly limited as long as they are pharmaceutically acceptable. For example, when the compound of formula (I) has a carboxyl group, a hydroxyl group or an acidic heteroaryl group (such as a tetrazolyl group), the base addition salts of the carboxyl group, the hydroxyl group or the acidic heteroaryl group, and when the compound of formula (I) has an amino group or a basic heteroaryl group, the acid addition salts of the amino group or the basic heteroaryl group, etc.

[0411] Examples of the base addition salts include alkali metal salts (such as sodium salt, potassium salt); alkaline earth metal salts (such as calcium salt, magnesium salt); ammonium salts; organic amine salts (such as trimethylamine salt, triethylamine salt, dicyclohexylamine salt, ethanolamine salt, diethanolamine salt, triethanolamine salt, procaine salt, N,N'-dibenzylethylenediamine salt), etc.
