The present invention provides a novel carboxylic acid derivative, a salt thereof or a hydrate of them which is useful as an insulin sensitizer, and a medicament comprising the derivative as the effective ingredient. More specifically, it provides a carboxylic acid compound represented by the formula (I), a salt thereof or a hydrate of them.
In the formula, Ar represents a 6- to 14-membered aromatic ring group which may have at least one substituent; R1, R2, R3, R4, R5, R6, R7 and R8 are the same as or different from each other and each represents a hydrogen atom, a halogen atom, a hydroxyl group, a C1-6 alkyl group or a C1-6 alkoxy group; X represents an oxygen atom or a methylene group; Y represents a group represented by the formula (II) or (III):
(wherein Z represents a group represented by the formula (IV):
(wherein R9, R10, R11 and R12 are the same as or different from each other and each represents a hydrogen atom, a halogen atom, a hydroxyl group, a C1-6 alkyl group or a C1-6 alkoxy group)); m is 0 or 1; and n is 0 or 1.
本发明提供了一种可用作胰岛素增敏剂的新型羧酸衍生物、其盐或其水合物,以及以该衍生物为有效成分的药物。更具体地说,它提供了一种由式(I)代表的羧酸化合物、其盐或它们的水合物。
式中,Ar代表6-至14元芳香环基,该环基可具有至少一个取代基;R1、R2、R3、R4、R5、R6、R7和R8彼此相同或不同,且各自代表氢原子、卤素原子、羟基、C1-6烷基或C1-6烷氧基;X代表氧原子或亚甲基;Y代表由式(II)或(III)代表的基团:
(其中 Z 代表由式(IV)代表的基团:
(其中 R9、R10、R11 和 R12 彼此相同或不同,且各自代表氢原子、卤素原子、羟基、C1-6 烷基或 C1-6 烷氧基));m 为 0 或 1;n 为 0 或 1。
