  • Patent number: 7968552
    Abstract: A compound which can be used as a pharmaceutical, particularly a insulin secretion promoter or a agent for preventing/treating disease in which GPR40 is concerned such as diabetes or the like, is provided. It was found that an oxadiazolidinedione compound which is characterized by the possession of a benzyl or the like substituent binding to the cyclic group via a linker at the 2-position of the oxadiazolidinedione ring, or a pharmaceutically acceptable salt thereof, has excellent GPR40 agonist action. In addition, since the oxadiazolidinedione compound of the present invention showed excellent insulin secretion promoting action and blood glucose level-lowering action, it is useful as an insulin secretion promoter or an agent for preventing/treating diabetes.

  • Publication number: 20100267775
    Abstract: A pharmaceutical agent having GPR40 receptor agonistic action, particularly a compound which is useful as an insulin secretagogue or an agent for preventing and/or treating diabetes mellitus. The present inventors have examined a compound having GPR40 receptor agonistic action, confirmed that an oxadiazolidinedione compound which has a substituent such as a benzyl group, etc. linked with a substituent such as a phenyl group, etc. through a linker at the 2-position of an oxadiazolidinedione ring, or a pharmaceutically acceptable salt thereof has an excellent GPR40 agonistic activity, and thus completed the invention. The oxadiazolidinedione compound has excellent insulin secretagogue action and anti-hyperglycemic action, and therefore can be used as an insulin secretagogue or an agent for preventing and/or treating diabetes mellitus.

  • Publication number: 20100152165
    Abstract: [Problem] To provide a pharmaceutical, particularly a compound which can be used as an insulin secretion promoter or a preventive or therapeutic agent for diabetes mellitus and the like diseases in which GPR40 is concerned. [Means for resolution] It was found that novel carboxylic acid derivatives or salts thereof, characterized in that carboxylic acid is linked to a 6-membered monocyclic aromatic ring via two atoms and said aromatic ring is linked to a nitrogen-containing bicyclic ring via a linker, have excellent GPR40 receptor agonist action. In addition, since the carboxylic acid derivatives of the invention showed excellent insulin secretion promoting action and blood glucose reducing action, they are useful as an insulin secretion promoter and a preventive or therapeutic agent for diabetes mellitus.
