The present invention provides a novel carboxylic acid compound, a salt thereof or a hydrate of them useful as an insulin-resistant improver, and a medicament comprising the compound as an active ingredient. That is, the present invention provides a carboxylic acid compound represented by the following formula (I), a salt thereof, an ester thereof or a hydrate of them.
In the formula, R1 represents hydrogen atom, hydroxyl group or a C1-6 alkyl group etc. which may have one or more substituents; L represents a single or double bond or a C1-6 alkylene group etc. which may have one or more substituents; M represents a single bond or a C1-6 alkylene group etc. which may have one or more substituents; T represents a single bond or a C1-3 alkylene group which may have one or more substituents; W represents carboxyl group or a group represented by the formula -CON(Rw1)Rw2 (wherein Rw1 and Rw2 are the same as or different from each other and each represents hydrogen atom, formyl group etc.) etc.; represents a single or double bond; X represents oxygen atom or a C2-6 alkenylene group etc. which may have one or more substituents; Y represents a C5-12 aromatic hydrocarbon group etc. which may have one or more substituents and which may have one or more heteroatoms; and ring Z represents a C5-6 aromatic hydrocarbon group which may have 0 to 4 substituents and which may have one or more heteroatoms.
