Publication number: 20090302265Abstract: During the investigation of the mechanism that cellular water in woody plants growing in cold districts keeps liquid state at low temperature, the inventors have studied to identify the causative substances. As the results, the present inventors identified supercooling promoting agents in woody plants. The supercooling ability of identified flavonoid glycoside and synthesized flavonoid glycoside with similar structure was tested. It was found that the supercooling promoting agent comprising these flavonoid glycosides enables to stably supercool bulk water at low temperature for long-term. The aqueous solution containing the supercooling promoting agent of the present invention is useful to store biological materials at low temperature.Type: ApplicationFiled: July 11, 2007Publication date: December 10, 2009Inventors: Seizo Fujikawa, Jun Kasuga, Yasuyuki Hashidoko, Keita Arakawa, Yukiharu Fukushi

Patent number: 7622450Abstract: The present invention relates to novel flavone C-glycoside derivatives or salts thereof, especially those showing an anti-allergic effect, and compositions containing them. Recently, cases of allergic diseases, especially pollenosis and atopic dermatitis have increased to such a degree that they have become a social problem. Flavones and their glycosides have been reported to have the effect of inhibiting histamine release from mast cells or an immunosuppressive effect and expected for application as allergy therapies. However, most flavones exhibit their effects only at high doses, so that effective compounds at lower doses are highly desired. The present invention provides novel components capable of treating allergic diseases at low doses and compositions containing them.Type: GrantFiled: July 3, 2003Date of Patent: November 24, 2009Assignee: Suntory Holdings LimitedInventors: Yoshiyuki Ishikura, Kuniro Tsuji, Haruo Nukaya
