Patent number: 7968552Abstract: 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.Type: GrantFiled: April 23, 2007Date of Patent: June 28, 2011Assignee: Astellas Pharma Inc.Inventors: Kenji Negoro, Fumiyoshi Iwasaki, Kei Ohnuki, Toshio Kurosaki, Yasuhiro Yonetoku, Norio Asai, Shigeru Yoshida, Takatoshi Soga

Publication number: 20100267775Abstract: 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.Type: ApplicationFiled: October 22, 2008Publication date: October 21, 2010Inventors: Kenji Negoro, Fumiyoshi Iwasaki, Kei Ohnuki, Toshio Kurosaki, Kazuyuki Tsuchiya, Kazuyuki Kuramoto, Shigeru Yoshida, Takatoshi Soga

Publication number: 20100152165Abstract: [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.Type: ApplicationFiled: November 29, 2007Publication date: June 17, 2010Inventors: Kenji Negoro, Kei Ohnuki, Toshio Kurosaki, Fumiyoshi Iwasaki, Yasuhiro Yonetoku, Kazuyuki Tsuchiya, Norio Asai, Shigeru Yoshida, Takatoshi Soga, Daisuke Suzuki

Patent number: 5196990Abstract: A metal printed board having circuit conductors on the surface of an insulating plate layered on a metal plate, wherein grooves formed in the portions of the metal plate which face the circuit conductor. The electronic parts mounted conducts into the metal plate through the solder portions and the insulating plate just thereunder. Accordingly, the presence of the grooves little impairs the thermal conduction. The stray capacitance between the conductor circuit and the metal plate because of the formed grooves, is considerably reduced, so that the signal leakage and noise sneaking are minimized.Type: GrantFiled: March 25, 1992Date of Patent: March 23, 1993Assignee: Fuji Electric Co., Ltd.Inventor: Toshio Kurosaki

Patent number: 4744236Abstract: Double-stem type extrusion method and apparatus used for extrusion-molding rod-like and tubular products. In order to upset a solid or hollow billet (5, 5A) supplied to a container (1), the end of the container (1) which is on the side of a press stem (6) is closed with a blistering-preventing cover (11) which is not moved relatively to the container (1). A pressure is then applied to the billet (5, 5A) from the side of a die (8) to start the yield deformation thereof from the same side thereof. As the yield deformation movement of the billet (5, 5A) progresses, the air existing between the inner surface of the container and billet (5, 5A) is discharged from the portion of the container (1) which is on the side of the cover (11).Type: GrantFiled: December 10, 1985Date of Patent: May 17, 1988Assignee: Kabushiki Kaisha KobeseikoshoInventors: Akira Asari, Masakazu Ueda, Takahisa Tabuchi, Munenori Soejima, Toshio Kurosaki, Masaru Sugamoto
