It has been desired to develop a pharmaceutical composition, which is used in agents for preventing and/or treating various diseases related to PDE10 (e.g. mental disorder and neurodegenerative disorder). The present invention provides: compounds having PDE10 inhibitory effect, in particular, compounds having a 4-heteroarylpyrazole-5-carboxylic acid amide structure represented by the following formula (I), or their pharmaceutically acceptable salts, or their solvates; pharmaceutical compositions comprising, as active ingredients, the compounds, or their pharmaceutically acceptable salts, or their solvates; and medical use of the compounds, or their pharmaceutically acceptable salts, or their solvates. 

Pyrazole derivative

[Problem] To provide a GPR40 activating agent having, as an active ingredient, a novel compound having a GPR40 agonist action, a salt of the compound, a solvate of the salt or the compound, or the like, particularly, an insulin secretagogues and a prophylactic and/or therapeutic agent against diabetes, obesity, or the like. [Means of solving the problem] A compound of Formula (III): 

Cyclic amide derivative

[Problem] To provide a GPR40 activating agent having, as an active ingredient, a novel compound having a GPR40 agonist action, a salt of the compound, a solvate of the salt or the compound, or the like, particularly, an insulin secretagogues and a prophylactic and/or therapeutic agent against diabetes, obesity, or other diseases. [Means of Solving the Problem] A compound of Formula (1): 

[Problem] To provide a GPR40 activating agent having, as an active ingredient, a novel compound having a GPR40 agonist action, a salt of the compound, a solvate of the salt or the compound, or the like, particularly, an insulin secretagogue and a prophylactic and/or therapeutic agent against diabetes, obesity, or other diseases. [Means of solving the problem] A compound of Formula (I):  (where n is 0 to 2; p is 0 to 4; j is 0 to 3; k is 0 to 2; a ring A is an aryl group which is optionally substituted with L or a heterocyclic group which is optionally substituted with L; a ring B is a benzene ring, a pyridine ring, or a pyrimidine ring; X is O, S, &#x2014;NR&#x2014;; and Rto Rare specific groups), a salt of the compound, or a solvate of the salt or the compound.

3-hydroxy-5-arylisothiazole derivative

[Problem] To provide a GPR40 activating agent having, as an active ingredient, a novel compound having a GPR40 agonist action, a salt of the compound, a solvate of the salt or the compound, or the like, particularly, an insulin secretagogue and a prophylactic and/or therapeutic agent against diabetes, obesity, or other diseases. [Means of Solving the Problem] A compound of Formula (I): (where p is 0 to 4; j is 0 to 3; k is 0 to 2; a ring A is a specific cyclic group; a ring B is a benzene ring, a pyridine ring, or a pyrimidine ring; X is &#x2014;CH&#x2014;, O, &#x2014;S(O)&#x2014; (i is 0 to 2), or &#x2014;NR&#x2014;; Rto Rare specific groups),a salt of the compound, or a solvate of the salt or the compound.
